PCV Ignition Module fixed mine.

I think we have a much different sense of humour over here, or u guys r really sensitive, geez. I was having a dig at OUR politicians and bureaucrats for not having Sirius etc. Life threatening, you haven't had it die on you, or surge mid corner?? - read my last post, sorry, please.:tongue:

 

What is your opinion how much of the jerkiness comes from the final drive (not being chain) or the engine? There is jerkiness when there is no load, constant throttle and speed 20-40 km/h (then you have to slip the clutch).

 

G'day Pete2 IMHO the lash in the final drive and output does play a considerable role in the problem in that scenario, there will be heaps of naysayers though I'm sure.
At that speed I would be in either 1st or 2nd though, what gear would you be in at that speed?
There is none or negligible lash in the drive shaft, universal joints and diff, at least on mine. The spring damper mechanism does not seem up to the task, not sure if a chain would fully disguise the "issue" either. However, the only bike that would get me back to a chain drive would be the release of the RCV.

Maybe you are correct. The reason might be then too nervous throttle control on small openings when there is no load on the engine. If so there is nothing much you can do about it (maybe soften it with ignition control and retard it a bit on those problem areas?). Almost everybody seems to be anyhow talking about it. A nice way might be to have a new ECU update (not the existing update that I have and didn't help much).

This is not a big problem and might not be even worth to mension in such a nice bike!

 

You didn't answer about which gear you are in at those speeds. I am a non believer in the ECM update, I think it is a myth, AFAIK Honda do not put flashable chips in their ECM's. I am still waiting for someone to prove me wrong, I wish they would.

 

Gear is either 1 or 2 on those speeds.

 

VFR1200 is the 4th shaftie I have owned. Also test rode quite a number of other shafties, both ST's and cruisers. The Viffer Grande is one of - if not - the best in terms of smoothness and lack of gear lash. Or may be I should say "perceived gear lash", because you cannot engineer lash tolerance completely out of this sort of gear drive without affecting longevity. Honda did a remarkable job to make gear shift transition smooth. My last shaftie - C14 - OTOH was next to impossible to shift smoothly in the lower 2 gears at low revs, regardless of how I tried.

As for drive line noise, I always wear earplugs when riding so... Seriously, even when I do hear it, it doesn't bother me. A bike is supposed to make noise. That's part of the visceral appeal of motorcycling that draws me to the experience. It's like some people complain about the very common off-throttle deceleration pops from the exhaust and would go out of their ways to "fix" it, often by deleting the PAIR valve. Granted, some bike pop louder than others, but the pops are completely normal and doesn't not hurt the bike. To me, I rather like the decel burble of a lot of the bikes I owned, including the VFR1200. The Sprint ST's 1050 especially makes a glorious decel burble. Still, I am not gonna tell those that don't like it they are wrong. Everybody perceive things differently.

Whatever makes your riding experience a better one is fine by me.
