Bad shifting

[elavir]

Hi all,

my GSXR750L,1990, is not shifting neat above 10000rpm. It sometimes( not doing it all the time) feels like the dogs of the gears clicking one over before they grip. Is there something to do about it besides splitting the cases :-( 

TIA 

Cheers Richard.

Hello and welcome to OSS.

Please take some time to introduce yourself in General Chat, and post some pics of your 750L.

One fix is to do what I did, install an 1100 engine, so you don't need 10000 + rpm anymore.

and make sure the chain & sprockets are in good condition and adjusted correctly.

Shift at lower revs  and don't wait for the valves to come through your tank before you go for the next gear

The ratchet pawls and springs behind the clutch are worth checking. Other wise its split cases and check the forks and dogs.

Do use the clutch on up shifting? 

Normally a roll of the throttle and firm tap on the lever is enough for the gears to slip in a treat. Clutching slows everything down too much.

Thnx mate, i will check that.

Btw, i do use the clutch because when you dont it isnt good for the gearbox i've been told.

Try without the clutch. I find shifts are smoother and much faster. It's how they are designed to work. 

It's not a syncro box like a car
