  1. Eastern Oregon is my favorite destination for cheese grater roads.  I have so much fun out there that I don't mind the increased wear one bit.
    There's a price to be paid for good traction, for sure...just sucks when freeway commute eats the tire down the middle before you get to enjoy the rest of it in the twistys.
    That's why stuck on the Avon's with dual compound, harder rubber in the centre portion :) 
     
     
  2. I install last week these spark plug CR9EIA-9 stock no. 6289. Start the CP3 engine and overheated pipes red after about one minute. 
    Is there somebody who have or know the reason of this problem please.
     
    Odometer at 10 600 km after one season.
     
    Thanks for your help !
    As other have hinted on here, there's nothing on the NGK site that would indicate that plug type has an effect on how hot the engine will run, rather that one has to select the right plug for the right temperature application. They also list some factors that WILL affect the engine run temperature (and thus affect the performance of the plug), and of course timing is one of them. Assuming that the plug itself cannot make the engine run hotter... was the plug swap the only task performed on this bike? No valve/timing work, ECU flash or otherwise? If not, could it be a bad plug and/or bad electrical connection, gaps not set right?
    That's not how I understood the NGK commentary,  
     
    "...When you need your engine to run a little cooler, run a colder plug. When you need your engine to run a little hotter, run a hotter spark plug..."
     
     
     
  3. The OP states that NGK recommended and he fitted plug CR9EIA-9, and later CocoST mentions an issue of hot pipes.
     
    From the NGK site:
     

    UNDERSTANDING HEAT RANGE 
    One of the most misunderstood aspects of spark plugs is its heat range. It is believed by many that the heat range measures spark temperature or intensity. This is incorrect as the heat range is actually a measurement of the plug’s ability to transfer heat away from the tip of the spark plug. One cannot change the temperature of how hot a fuel burns.
     
     
     
    A hot spark plug has an insulator design that will be slower to draw heat away from the plug tip (thinner insulator mass), whereas a cold plug has an insulator design that will be faster to draw heat away from the plug tip (thicker insulator mass). For a spark plug to function properly it must have a tip temperature hot enough to invoke self-cleaning, while remaining cool enough to avoid pre-ignition.
     
     
     
    For most vehicles, the factory recommended heat range is sufficient; however, on some modified or special-use engines, alternative heat ranges may be necessary. Often hotter heat ranges have been used to attempt to correct an underlying fuel or oil consumption problem; this is merely a cover-up fix and the underlying issues will ultimately have to be addressed.
     
     
     
    The image below is a representation of the difference between a hot and cold heat range. NGK spark plugs’ heat range goes from 2 (hottest) to 11 (coldest).
     
    So clearly different plugs will run the engine at different temperatures. On selecting Heat Range, NGK state:
     

    HEAT RANGE SELECTION Let's make this really simple: when you need your engine to run a little cooler, run a colder plug. When you need your engine to run a little hotter, run a hotter spark plug. However, NGK Spark Plugs strongly cautions people that going to a hotter spark plug can sometimes mask a serious symptom of another problem that can lead to engine damage. Be very careful with heat ranges. If you are changing heat ranges, contact NGK Spark Plugs tech support for professional guidance, 877-473-6767 prompt #2.
     
    With modified engines (those engines that have increased their compression,) more heat is a by-product of the added power that normally comes with increased compression. In short, select one heat range colder for every 75-100 hp you add, or when you significantly raise compression. Also remember to retard the timing a little and to increase fuel enrichment and octane. These tips are critical when adding forced induction (turbos, superchargers or nitrous kits), and failure to address ALL of these areas will virtually guarantee engine damage.
     
    An engine that has poor oil control can sometimes mask the symptom temporarily by running a slightly hotter spark plug. While this is a band-aid approach, it is one of the only examples of when and why one would select a hotter spark plug.
     
    There is also quite a good description on plug basics here Linky Linky to NGK
     
     
    On the NGK site, when looking for plugs for the FJ-09 / Tracer NGK only list a "Standard" plug, NOT an Iridium alternative. The part No for the standard plug is CPR9EA-9 # Stock Number 2308
     
     
    It sounds to me as though the Iridium plug CR9EIA-9 probably is the equivalent to CPR9EA-9 ... but that doesn't explain why there is no iridium listing on the NGK site for the FJ09?
     
     
    Finally as a comment to CocoST, are you sure that you actually fitted the correct plug (id est, did you check the actual plugs? - who know's whether they accidentally ended up in the correct box?
     
     
  4. I had those spark plugs installed recently. Probably have gone a 1000 miles on them so far. Nothing different that I have noticed. But its been freezing, and the only thing I can(not!) feel or notice are my frosted fingers.
    Have you tried those hand warmer things that hang down from the front of the engine?....some say they get toasty red hot.

    Your pipes got red hot after one minute? I don't know enough too comment properly... But I wouldn't think one minute was long enough...
     
    My understanding is that pipes get hot (and turn blue when cooled again) when a bike is running lean, or on preignition, I can only think that plugs are hotter type so igniting the fuel sooner?
     
    Anyone else care to comment?..I'm interested.
     
     
  6. We used to extend dirtbikes throw out arms to do the same thing at the expense of longer travel obviously.. Fwiw that dot should line up with the pointer on the case too when the freeplay is taken up to maximise the leverage effects.
    Yes, the dot & arrow should been aligned, but because the Tracer had bad clutch cables, this bike was swapped out with an R1's (higher quality) cable. The R1 cable is significantly longer measured end-to-end and left me with no more adjustment. 971f1b3ed5ef36a7a19bae961204a7e0.jpg
    R1 cable installed

    Clutch adjustment before Bolt's actuator swap
     
     
     
    I took this chance to shift the actuator a notch outwards, to gain back a bit of cable adjustment on my clutch lever, that's why the dot aren't aligned. On stock Tracer's clutch cable, it is not necessary.
     
     
     

     
    That looks like a good idea. I wouldn't mind doing that to mine. Can I ask with what you swapped the lever arm please? (throw out arm? never heard that expression in the UK but that may just be my ignorance) is that another stock Yamaha part? Would you have a part number (or bike model) please?

  7. Shoei X-Spirit, Shoei GT-Air and Arai Tour X4
    excellent choice sir.  
    I bought an x4 last week to replace my shoei neotec that I bought six months ago to replace my tour-x3, 7 years old. Very pleased with the x4...
     
    The shoei I have given to a friend.
     
    The x4 is better than the shoei, and an improvement on the x3.
    by way of update. The X4 top vents rattled and Arai sent some replacements...except they sent the wrong ones. Anyway I made one good set out of all bits.
     
    Next issue is when I came to fit the pinlock visor, that doesn't fit. And I also discovered multiple cracks on the visor radiating out from the left hand pivot point. Quite worrying for a six month old helmet.
     
    Anyway its gone back to Arai..we'll see what happens next.
  8. Or where you need to lock to cut through surface debris which is shorter.
     
    I agree panic braking, for all but highly tuned motoGP riders and their ilk, ABS will win.
     
    But I haven't had to panic brake in donkeys years..once..but need to lock many times a year to cut through surface dressing clippings and the like.
  9. The point for me at least is, Emergency breaking is extremely rare I can't even remember the last time I hit the breaks hard...yes... once in Wales 3 years ago.
     
    But I have, several times a year, every year and even a few times on the same journey wanted to purposely lock the wheel (only for a split second to cut in) to get through top dressing and debris to hit the tarmac underneath. ABS stops me having that option and consequently stops me stopping.
     
    All the research arguments for ABS is based on tarmac, and assumes for public highways that are not loose. Unfortunately the truth is, it often is, back country roads, wah out after heavy rains, top dressing with an inch of loose chippings are all real frequently encountered realities.
     
     
  10. Tongue in cheek English humour I'm afraid
    Thing is, I'm of English heritage, and I still didn't get it.  I think the paper bag is mine, eh.
    Its irony rather than comedy - On one hand I state that everyone agrees that they managed without, then conveniently forget the ones that phucked up at didn't survive, that, had they survived, would have welcomed ABS.
     
    "They" also say if thou have to explain it, then it wasn't funny. ...I'll get my coat.

  12. Just for the edification of my cousins across the pond, and elsewhere on this inter connected planet on which we reside, I thought you might like to know about
     
     
    SHARP. This is uk government sponsored independent research project into helmet safety. They are (verrry slowly) testing helmets for safety and rating them, with tests that are supposed to be a better reflection of accident conditions.
     
    See here: http://sharp.direct.gov.uk
     
    You can check out your helmet and see how good it is...
     
  13. Alternatively we could all just learn to ride properly - people seem to have managed for the last 50 years without...well, except the ones that didn't survive, of course.  Natural selection  init.
    At some point you could have said the same thing about radial tires, disc brakes, wet clutches, etc.  It's generally called progress.
    Tongue in cheek English humour I'm afraid
  14. Yes, this I believe to be true...and why I leave my ABS on.... 
     
    But equally many including me, see the dangers when you stop on dirt...that shouldn't be an issue for road riding, but in the UK sometimes it is.

    Mind you ABS is becoming so good these days that even on gravel it can far outperform non-ABS. 
    I have attended Simon Pavey's Offroad Skills course in Wales on a number of occasions.  The first time was probably about 9 years ago using the relatively new at that time 1200GS.  On the first day they said, "We've disabled the ABS and whatever you do, don't try and switch it back on!".  In those days you had much more control modulating the brakes yourself.
     
    Last time I did the course was about 2 years ago with the latest 1200GS with its various riding modes including Enduro mode.  This time they said on the first day "We've put the bikes in Enduro mode with the ABS [b style=text-decoration:underline]ON[/b], and whatever you do, don't try and switch it off!".  I must say it was amazing.  Riding down steep, gravelly inclines with slippery roots in your path and the front brake on and the bike just rolled down the hill in a controlled safe manner.  I was suitably impressed.
     
    CS
    Yes. I agree the technology is improving all the time. I'm not sure how sophisticated it is on the FJ/Tracer but I suspect it would out perform my 2009 KTM990. What was true then, may not be true now - I'm no expert on these things!
     
    And again, I'm leaving it on - in fact I might find some dirt and try it out - probably better to do it in a controlled way, than wait for "the day"
  15. 60 - 0 mph, very few riders can stop a motorcycle faster without, than with ABS. Even given perfect tarmac and a few practice runs, you will typically not outperform ABS. Complicate matters with unknown tarmac, variable coefficient of friction and adrenaline running through your veins....ABS is your friend. And the best part??? It's only there if you need it! If you're a braking GOD and somehow don't lock up the front or rear during an emergency, ABS is perfectly happy leaving you in control!
    Yes, this I believe to be true...and why I leave my ABS on.... 
     
    But equally many including me, see the dangers when you stop on dirt...that shouldn't be an issue for road riding, but in the UK sometimes it is.
     
    The idea of ABS front and non ABS rear sounds like a good compromise, but whether that's possible??
     
    For my riding style, I can't think of an incident where I have had to brake hard for the ABS to cut in (other than on loose gravel, where it was a hindrance) ...oh and in just trying it out.
     
    On a bike there is so much feedback through the bars even the slightest squirm is noticeable (remind me to change those Dunplops), on even sports cars that is far harder to detect imho.
     
    Err that's all really.
     
     
     
  16. There a definite pros and cons. Its not the panacea of safety that some believe, nor is it the curse of beelezebub.
     
    The reason I cited that experience was because the Q was asked "when can it ever be dangerous?" Equally one could ask, "when does it have its advantages?", and I think there could be some equally valid example.
     
    Pro and cons, no wrongs or rights, just opinions and preferences
  17. ...I hate abs, I think it's dangerous, and degrading to motorcyclists as a whole lol.
    I understand wanting to have a bike in its pure form without having as many of the electronics.. but how does ABS make a bike dangerous?

    I came down a tarmaced back country road (on a KTM 990 Adventure ABS, not had the Tracer kick in yet) in the village where I live, not THAT steep but rather prone to have gravel and dirt wash to the bottom after rain. 
    The road has a T junction at the bottom, so have to give way (yield) at the end.
     
    The speed limit is 30mph (its within the village) - I was doing maybe 20.  Light front brake, but on the gravel bit ABS kicks in, I stop in the middle of the main road beyond the stop line.  It was so slow and surreal, the bike was choosing to not let me stop, and there was FA I could do about it.  
     
    I have lived here for 23 years, so know every little bump on that road.   Had there been no ABS I could do what I always have done in that circumstance, a momentary intentional lock of the wheel would have cut through the shallow debris, caught the tarmac and the whole thing would have been a non-event.
     
    THAT is why it is (potentially) dangerous.  You don't have full control.
     
     
     
    (Its why dirt riders will switch ABS off, to give full control  - roads aren't always clean and sparkly... in fact today I went to the station down some back road slime mud covered on tarmac road, thinking "oh shit this thing has ABS" - I'm not a fan)
  18. No, easier than that. These are quick fasteners, no need to take the centre out.
     
    TO REMOVE
    Push the centre pin in - this releases the "legs" and allows you to pull the whole fastener out
     
    TO REPLACE
    Push the centre pin back so it protrudes beyond the front face (this also releases the legs)
     
    Place the fastner back into the hole and push the pin so it is flush with the surface - legs are now locked again
