My bike feels restricted and the top end is shy of a ton (95mph ish).

If it was restricted where would it be and what needs doing? I've checked the gear sensor and get the same reading on all the contact points. The CDI is just one big plug.

(1990 GK76a SP).

Have a look at your carbs see if the slides can move all the way up.

What happens when it hits the red line? doz it drop down to 2 cyliniders?

Considering mine is restricted, it will accelerate slower and take twice as long to get to top speed.
It will still reach 120 though.

Thanks for the replies.

It's got a dyno session booked tomorrow so hopefully they will find what's going on with it.

well on dyno it made 33bhp but something wasn't quite right and it wasn't restricted.... It turned out to be a dodgy spark plug

After this was replaced and cleared the fuel out (should have seen the smoke ) it made 58bhp.
