  1. the ones I have bought the 'nut' is pressed into the metal as a shape, not riveted on after the fact. but I come back to my earlier point. If you can't get it off with a solid grip with one hand or two it's on TOO TIGHT. Period. Never use mechanical advantage during install.
  2. I had a sudden and very brief surge then flame out while doing close-quarters battle during rush-hour at 70mph. Nothing seemingly wrong after the fact. But it might have been due to a loose ground wire. Revisit the major junctions and remove and inspect the battery connections and as a test, disconnect and manually short the side-stand switch and ride the bike that way for several days/weeks. It appears that with recent bikes, if the bike is in gear and you put the side stand down the ECU has been programmed to kill the engine. My older bikes did no such thing. It might be a Euro regulation that mandates this.
  3. if it's so tight you need to use the nut, it's on too tight.
  4. ride it cross-country? (kidding) https://www.cycletrader.com/listing/2015-Yamaha-FJ-09-5003810192
  5. DO NOT USE that oil!!! Indicated CST is at 100C, not 40c. see chart. https://sites.google.com/site/forksbymatt/resources/oil-list You generally want a high HVI oil in the 11-13cSt@40 for rear shocks use.
  6. What pressures are you running? I think you need some Shinkos. You should be able to hot-glue a 3" wide piece of car tire onto the middle and get a couple more miles. /JK
  7. Simple, put them in your vise and run a reamer into the hole. Or go oversize, press in an oil-lite and then ream to size. What, you guys don't all have a machine shop in your garden shed?
  8. I've got a set of 0-mile Dunlop GPR-300 if interested. I put Q3+ on the Z900RS not realizing it didn't come with the crappy D214 the sister Z900 comes with. https://www.dunlopmotorcycletires.com/tire-line/sportmax-gpr-300/
  9. and now Nitron is building the Adventure edition shock for us. First one was supposed to be here by now (any day) and I've got 2 more on order.
  10. Welcome to the best FJ09 forum on the planet. There are a skillion threads covering your topic of interest so you'll be reading for a couple of weeks.
  11. um, this forum has less than 5500 users and it's membership is heavily concentrated to North America. Furthermore the OP is a class of two (?) with more than 35000 miles on his engine. So by that reckoning 50% of high mileage engines have failed or tend toward failure. You can't possibly be serious that one can draw any conclusions from forum posts in the general case let alone this one.
  12. A new head does nobody any good if the valves and/or guides are not available. It appears to be a "known problem" at HQ in some circles. Hopefully @vinnie will be in contact soon with the defect investigation team. I don't think it's uncalled-for for Yam to ship a dozen complete heads from Japan and start doling them out for engines showing the same pathologies. With any luck it's probably just a single batch that's buggered. If the parts were truly unavailable there wouldn't be any new engines being built and no XSR, FZ09, nor FJ09 being produced for distribution and sale. Clearly that is not the case.
  13. Print all of it out and have the mechanic/dealer commit to paper (email but letterhead preferred) their observations and the process as they experienced it, all organized into a folder. Some better pics would be nice. Then walk into the reception and insist on the head of customer relations come down and meet you (call ahead for appointment? or as high up the food chain you can go) and also show them your shiny new Zuk and comment for want of a measly couple grand they have lost a customer forever. I would have a second packet ready and address it personally to the CEO. He might not read it but his secretary probably will and again, it could end up being forwarded to the head of CR. You'd be surprised how accessible some CEOs can be though.
  14. Well yes. The point was to say Yam engineering on the FZ07 team at least can still design a lasting motor.
  15. I'll just leave this here. https://fz07.org/thread/10189/78000-miles-and-running-strong/
  16. An air-cooled CB750 lasted well past 90k miles with just oil change and a new valve cover gasket. Yamaha's stance is inscrutable. Are they really so short-sighted that they can't conceive what this could do to them in PR? What does an already shipped head and full rebuild labor cost? $2000? And they think millions in fallout is a good idea? Or at the very least pissing off one dude royally who can easily reach thousands with social media? @vinnie once you get that copy send it to me or if you prefer contact Chris Ulrich at RoadRacing World directly. I think Yamaha's tune will change RIGHT quick. Even if in the USA an FJ might be lucky to see 5000 miles a year that's still only 8yrs of ownership. I can't see nearly all FJ's getting scrapped by that age.
  17. Since the plate is on a T-bar and spacers I imagine canting it a little shouldn't be a problem. Sorry I can't answer in the definitive.
  18. Your leg? Some people have rings of Delrin that purport to protect against minor scrapes. Assuming it's not destroyed just ride the bike with it's newfound character. Or resign yourself to having to pony up for a new can (200-300) and put the money in the piggy bank ahead of time. Looking at it again, the end-cone is going to take the brunt of it. Yosh can probably sell you the end cap and you can have someone chisel off the old rivets and install the new.
  19. The carbon on the old head makes it harder to see but the first angle on the new Intake is broader. I don't know about the angle. I question the angle choices made for the exhaust valve - that ridge is tiny and I'm not the least surprised it succumbed and got pounded flat. Like the new intake, I suspect the exhaust's first angle was too narrow a land and they widened it. It's also not unlikely there was insufficient hardening or incorrect alloy choice. Why in the world they didn't use inserts is beyond me. The width (and/or) angle changes will necessitate different valves for sure even if the pocket itself and the outer recess hasn't changed any. There might more 'surround' supporting the exhaust valve guide and it's hole. Poor lighting in the old head pics doesn't help.
  20. Hmm, this is gonna suck. Pity YAM isn't publishing a way to retrofit an old head with a precision pocket and press in an extended thickness beryllium copper-nickle seat. This level of materials/engineering fail deserves a no-questions-asked head replacement across the board regardless of any "extended warranty".
  21. spray the current studs/nuts with penetrating oil and leave overnight. It's not uncommon for them to corrode and end up coming out of teh engine block instead of the nuts coming off.
  22. crap valving courtesy of Yamaha and morons at KYB. You'll need more than just springs to fix the front (ie. something like my Intermediate or Stoltec's kit) The principal problem with the OE suspension in the crap-tasking valving. Springs can be ridden around, valving not so much. If your suspension guy didn't overhaul the internals when the spring was changed, you're just wasting time. If you look up "Japanese factory suspension since 1975" in the dictionary it'll say "sym. s h * t"
  23. always. They are crush washers and by definition are single-use only. You don't replace them because of mileage (or lack) but because when you install it indents the mating surface and you're not going to exactly match up the new exhaust to the previous indentations. It's a trifling amount ($13?) so having shelled out $6-800 for an exhaust it's just beyond silly not to do the job completely and correctly. If you want to save money, skip the next 3 Starbucks coffees and you're back to break-even.
  24. if the new spring was made to the OE specs, it has too much baseline preload. Yamaha cheated instead of doing the right thing. Get a standard length EIBACH and have a machinist knock out a spacer that yields at least 8mm of baseline preload. I guess I could make said spacer, I got a few OE shocks sitting around here and could figure out the dimensions... More to the point, aside from being short on sag, does the bike ride to your satisfaction?
