Looking for opinions on the Factory Pro shift star kit, having some problems with my bike jumping out of gear and some times not wanting to go into gear when down shifting, happend twice yesterday after a flat out 6th gear corner then trying to go down 3 gears for the next corner, just got a grinding noise as you get in a car when the clutch isn't ingaged right, had to slow right down and almost stop before it would down shift. Has anyone else had these problems? Will the factory pro kit sort it?

You sure all linkage is healthy and working?
K5 onwards has same parts as factorypro anyway.

bike is K6 and engine was rebuilt over winter so every thing should be OK internaly (I hope)

Check nothing in rearsets is bent, no friction, nice slick movement.

Hi had the same problem myself..............................
turned out to be nothing more than new boots!!! #-o after click up a gear the lever was resting on my new and much stiffer boots and not returning back to its normal postion then when id go for another cog or try to go down it would just select a box of neutrals............all i did to cure it was extend the gear lever cured it straight away hope this helps might be worth a look

was at the same circuit last week, same boots ect done 60 laps and it never happend once. Race yesterday, 2 false neautrals and 2 times it wouldn't go into gear from 6th. Had these problems last season to but a couple of people told me SV's were common for this.
Have you a quickshifter on?

I do Yvonne.
Fitted the factory pro kit recently and most false neutrals eradicated since - added the clutchless shifting technique as well and now had a broken third gear. Only so much racing treatment a roadbike will take?

It certainly was a problem with the curvy's and I had to fit one, but the K6 hasnt given any probs...... yet!
Did you check all the linkage after the off at Cookstown?

I had the same probs last year Yvonne, its a pain in the **** but I put up with it on the circuits. Dont fancy hitting a false neutral or not being able to select a gear in a road race at a road end though, i'd be through the hedge! Might be what happend at cookstown, but that happend so fast its hard to know, one of the guys after the accident asked me did I hit a false neutral. :confused:
I did notice that your gear linkage (the one on the splined gear shaft) sits futher out than mine from the frame, your linkage seems to have a slight off set where as mine is straight which meens my link rod from my rearset is touching the frame. Maybe this isn't helping things?

They changed the shift star to the similar shape to a factorypro one after K5
You sure all linkage is healthy and working?
K5 onwards has same parts as factorypro anyway.
They are not the same - put them side by side and grab calipers and a mike.
They certainly don't work the same.
I just replaced 05 star and spring with a Factory Pro star and spring in a dl650 and the customer was amazed at the improvement over the late model Suzuki shift parts.

Did you check the dogs teeth on the gears when you had the engine apart, as they will round off, you have too look closely as it only takes a slight wearing of the edges to start causing the cogs to not engage completely. This is made worse by going up the gears without the clutch when racing. Quick shifters make it even worse. The 3rd gear is usually the most worn.

I was thinking - about quickshifters causing dog damage -
A quickshifter with the kill duration set too low might do damage to the dogs because the power came back on before the shift mechanism fully rotated the shift drum to get to where the shift forks slid the gears over and fully engaged the dogs n slots?
We use 2 guys to set qs kill duration on the dyno. Guy number 1 to test the shifting and guy number 2 empirically deriving the best duration based on guy number 1's feedback, all the while throwing in spurious kill duration values to keep guy number 1 honest.
Doing it that way gets it better than +/- a couple ms resolution.
But most of the race bikes we check are kinda "off".

I always seem to say this after someone has had an off, but have you checked that the circlip on the shift rod has not been displaced from its groove? The rod that goes into the crankcase and has the shifter plate on the clutch end. Where it emerges from the crankcase near the front sprocket, there is a groove and circlip to prevent it being able to slid inwards (rightwards as you sit on the bike) and disengaging from the shifter, followed by hitting the clutch basket. Hopefully you're with me! Because the circlip is a tight-ish fit on the shaft when outside of the groove, then it doesn't just slop back and forth, so it isn't immediately apparent.
