  1. To be fair most cars have hydraulic lifters that automatically adjust the clearance/lash. Motorcycles dont/cant have this as the rev ceilings tend to be much higher and the mass of the valve system has to be a lot lighter to avoid exceeding the stress limits of the alloys used. Unless a lifter packs up on a car [sometimes you can hear an engine that has a habitually stuck lifter when cold - a tick that goes away after 20 seconds] then there is zero chance of a valve burning out due to not closing fully, where as a bike which has clearances out of adjustment runs a real risk of burning out a valve and doing some expensive damage. Having said all that I have checked a lot of valves of a lot of bikes [including some 20-valve heads] and have only seen a few exhaust valves that really made me think: 'wow, that is close to valve not sealing and being burned-up'. The maddest thing about jap bikes is that the clutch material wears down and into the oil - which is circulating to lube the entire engine. It's a very contrary design imo, but the manufacturers like it as the costs of manufacture are low and the japs really are quite stuck in their conventions on engine design (very little has changed in 25 years in their engine designs) - it just means oil should be changed at the designated intervals to ensure the oil isnt excessively loaded with clutch particles. Oil threads are the work of the devil....
  2. I used to 'hallucinate' when working on bikes and cars - the empty beers bottle on the bench next to the vice, was always a dead give away that i'd been 'hallucinating' whilst spannering.....
  3. Annoying for you that you eventually ran out - but that is decent economy - 61mpg-uk equals 73mpg-us.
  4. I chopped in my Niken for the current (GSXS1000FA) generation. [Loved the Niken and that engine, but my shortness meant it was only a matter of time before I dropped it]. The engine on the GSXS - which is carried over from my model - is excellent. I dont care about outright performance - but itll cruise at 95mph and at 70mph it's so frugal [70mpg-uk]. Very smooth. But the fuelling was dreadful - way worse than mt09/tracer/xsr/niken - almost dangerous so I had to get it flashed. The guys with the new unfaired bike are saying Suzuki have cured that and it pulls cleanly and hard; and i believe them. The suspension was also crap, the rear shock is as bad as the original mt09s, so i bunged in a YSS unit. I am now starting to really like the bike and this new one looks stunning [the model i have is fugly]. The electronics package is also good. I cant justify p'exing mine, but I suspect these will sell very very well.
  5. I've used Italian roads many many times. They tend to be very liberal about speed limits - I wouldnt speed in towns/villages, but lots of italians do. I cant remember seeing a speed camera, the carabinieri do patrols, but they never seem that bothered about motorcycles [or cars] and unless you are being an idiot pay no interest. No idea about parking for cars - bikes park anywhere [on the pavement/sidewalk often] as long as it doesnt obstruct. Most cities have multistories and towns villages are often pretty liberal about parking. The autostradale accepts most forms of payment - ive just used my debit card or euros cash. It's not too expensive, but on a motorcycle often better bypassed if you can use more interesting routes. Love italy, stunningly beautiful, friendly folk. Worst thing is the lunchtime closing that affects so much stuff between 1130 and 230pm. Where are you going?
  6. Not sure about stateside, but surely - with the bike only a month out of warrantee - the dealer will look at it gratis. Here in the UK the end of the warrantee wouldnt automatically be the end of all intervention. Can you call the dealer or Yam USA and see what they say?
  7. Not sure if I should be in here. My Niken GT isnt dead, but it has been moved on. I genuinely loved it, but I am 5'6" and after nearly dropping it on a steep camber (British roads are very, very cambered) I decided that it was only a matter of time before I did drop it and it was gonna be expensive to sort. Traded it in for a Suzuki GSXS1000, which is not nearly as plush or refined, but has a seat heigh of 30.5" and is much narrower. I enjoyed my Niken, but not for the first time my short stature has limited my time with a bike.
  8. I have repaired worse myself (but do so understanding the risks) and not had a problem. Either some pieces of rounded hardwood or better some rounded nylon blocks. One on the side to strike and one on the other side of the buckle. Use a 20oz hammer on the blacks. You'll be able to get that back to almost where it should be (but not quite as it has yielded). My daily NC700 has had a repaired buckle for 40,000 and is fine. Tyres seal and it hasnt cracked. Cheaper than finding someone and easy enough.
  9. I can see some police forces using Nikens. The stability of the bike is a major consideration for them. Yamaha would be sensible to create a prototype for police forces to judge the merits of it.
  10. The wheels are interchangeable, but tyres are directional. So you can flip the rims across, but the tyres would run backwards.
  11. I've bought low octane (RON not MON) when ive been in Eastern Europe (but on other bikes not the Niken) and not had pinging - the timing is set very conservatively to suit, even at large loads and large throttle delta conditions they wont ping-up. Some modern car engines can detect knock by analysing the signal from the CPK - in the same way they can detect misfires, through looking at small changes in angular velocity against the expected values. I think they look for changes in the 3rd order or higher [angular jerk] and if certain patterns emerge [quickly] then it is calculated by the algorithm as knock/pink/ping and mitigation enabled (retard timing) - i had a few 90s cars where you could trigger knock and hear the system kick in when you gave it a large load. I did remember a motorcycle engine designer saying on another forum, that the high revs means that the valve clatter can be mis-detected as knock by knock sensors (basically a very clever piezo microphone/accelerometer). Although I would have though signal conditioning/signal processing would be able to get around that now - which makes me think that the conventions of bike design are the main factor (like the clutch running in oil or the use of springs for timing chain tension - relatively antiquated, but acceptable and cheap). Given as much timing advance as is safe is good for emissions, and knock is bad for emissions (NOx goes through the roof) that EURO4 or 5 would have been drivers to add the extra sense and adapt function, but they do know what they are doing and slightly retarding is cheap [see above].
  12. The Niken costs £13500 - about us$18500. The GT costs £15000 - about us$20600. Both are inclusive of VAT (@20%). Both are currently available with 0% finance, and i suspect dealers would offer finance on the RRP (the prices above) or offer higher rate finance if they discount. Discounts on Yamahas in dealers are very common, the Niken/GT both have substantial discounts around the UK, probably partly the quirkiness and partly the lockdown and financial downturn.
  13. id do the same. here in the uk, a dropped bike would be worth wholesale salvage - i see no reason why that would be different on the other side of the pond. A small amount off does not cover this and they need to supply a new bike.
