Hi all, I need some help here. something doesnt seem right to me.
I have in the last few weeks stripped, cleaned, measured and dialed the inner workings of me beloved xs.
reason for the tear down? dropping out of 2nd in neutral occasionally (though i've read a lot of posts on here and it seems like i'm not the only one)
the other reason is 45mph was the max i could do before it got all vibey and scary-noisy.
having checked the selector drum and shifting forks, im satisfied that they are in good nick. The 'stopper lever wheel' was shonky so i got a better one. feeling good about that.
So now i'm looking at the gear clusters
both the Drive Axle (front sprocket) and the Main Axle (Clutch) seem to have too much side play. I played with these for a while after reinstalling them. popped it into Neutral (amazing, it's never been that easy
) i pushed them as far to the left as they'll go then as far to the right, one at a time then both together. at each stage i checked the freeplay in the shifter forks, to check the clearance between the pinion gears and the wheel gears' dogs.
I CAN MAKE THEM TOUCH!!! sounds horrible even at 15rpm.
as i had a few spare tranny parts around i thought to shim the small needle bearing on the Drive Axle, (between the bearing and the blind bearing housing in the casing) this shim was exactly the same as the one that goes between that same bearing and the 2nd pinion gear. so that has taken up the slack without preload and stops those dogs from fighting. I guess theres a couple of thou movement in it now.
Finally the actual QUESTION. (if you're still with me, I thank you)
Will this be a problem once the engine is hot and expansion does its thang?
and while I'm at it.
Is there a definitive spec for end float on these 2 gear cluster shafts.
I WILL trawl through all those manual PDF's if I have to but I was really looking forward to bolting the cases back together tonight, and i reckon y'all know the feeling and will be quicker off the mark than that job.
