Guys,

I am hoping some of you got input on this.

My bike has 15w50 Fully Synth in it (600 miles on it). I adjusted the chain and it made a substantial different when it was cool. In fact most of the clunkyness / knockyness went out of the gearbox.

However when its well warmed up needle just above the first indent after 30 mins riding ...it becomes clunky again.

Sticking it in first makes the bike jump a bit...its not nice.

What is the clutch mileage on one of these bikes? The clutch seems fine when pulling away from a stop, but ..perhaps its dragging a bit.

Maybe the oil is too thick for my type of riding..oil made a massive difference on the gearboxes on my classic japanese bikes..maybe ?

Any help would be good. I love a nice smooth gearbox :-)

Either fix it or re-educate it with smooth, 'preloaded' shifts...clutch please.

Also, see if shifting into 2nd prior to 1st helps things out (even if at a stand-still). You might want to roll a bit with a careful application of front brake and the clutch to ease entry into 2nd if necessary. Nothing more than the clutch should then be necessary for the shift from 2nd to 1st.

Well, perhaps its not that bad !! ;-)

When its cold the bike doesnt jump going into first.

Which leads me to beleive that there is something wrong with the clutch or the oil.

The bike is VERY rideable. But I am a mechanic with a penchant for machanically perfect machines...

If that makes any sense ! LOL..

Is this motorcycle-specific oil you're using?

Yep.

Silkolene 15w50 Pro 4 Fully Synthetic.

The first thing to do is replace the clutch hydraulic fluid if it has any age on it.

Yep done that first off.

I would like to say at this point that I rode a 96 Daytona today and his gearbox was identical.

It appears I am being to picky. I suspect things will improve when I use a thinner oil next time.

Also also lowered my gear leaver and now have marginally more lift...So I am all together more confident that its all OK :-)

Its not as smooth as an R1 I had recently, I guess thats why I am being picky. Dont get me wrong, I prefer the Daytona, not as fast, but..more fun all round IMHO.

I completely understand your comparison with the R1's gearbox.

IMHO, these bikes need to be shifted differently than the newer lightweight modern bikes which are usually shifted with one stroke of the gear change lever in just one full sweep 'click'.

As I stated above, it's best to shift these transmissions by first 'preloading' the shift lever ever so slightly (up to the 'soft stop') before clutching and clicking the next gear. I know this might sound stupid to some, but once you get it down with the required feel and timing, you'll be experiencing quick positive shifts.

Note: it's best to try this in the taller gears (3-5+) before mastering it out of 1st and 2nd gears. This applies to upshifts only! ... as downshifts are best achieved by blipping the glorious triple.

I have also found that by shifting in the manner above, my transmission's shifting action has actually improved... i imagine smoothing out the dogs & forks.

I don't even think about it these days but you are right on the money Buckwheat that is deffo the way to success....;-)

Thanks Guys, I'll give that a try when the beer wears off :-)
