I just got a CBR600 f2 1992 and is seams like it lacks power, it sounds like it miss fire alot and hard to start. I think I'm going to try a tune-up for this; but, for now my concern is when I drive it and I go into 2nd gear, it slips into neutral and think one time it slipped from 3rd into 2nd or neutral. Do I have to replace the transmission parts and gears? Is it a clutch problem?

Please advise!

Thanks!

 

my bike does not slip knock on wood, but do a search i think i have read a bunch of guys had the same problem slipping into neutral from second, it might have been f3s it was common on but just a heads up.

 

not sure if this will help, but my bike was doing the same thing and I noticed that the shifter linkage was loose and wasnt allowing the transmission to go into gear all the way. I tightened the linkage up and it works perfect.

 

my bike doesnt actualy slip out of gear, but ive noticed that if i dont hit 2nd hard i hit nuetral and look like an idiot when im showing off lol. and some times when im in it hard it will feel like i engaged the clutch and just tach out when not actualy tuching the clutch but thats only in like 9 and 10 x1000 rpm, normal or something to look into??

 

You have to make sure you're shifting firmly to avoid hitting neutral on the way to second. The slipping problem sounds like worn clutches or not enough freeplay in your clutch cable, possibly even weak clutch springs. You want about 2-3 mm of play in the clutch lever (measured at the point where the lever meets the clutch perch). If there is no freeplay, your clutches are never fully engaging and therefore will wear quickly.
