Hi guys.. i kind of new here but i'm always checking out this forum and learning new stuff ..

I'm having a bit of a problem with my bike..

I own a 2000 ZX7 and it runs great but when i go into 4th gear it doesn't want to go any faster than 70? but in 3rd gear i can go all the way upto 100mph

anyone have any idea what happened?

 

what about 5th and 6th? same problem?

I've only noticed similar behavior on carbed bikes that were not getting enough fuel pressure (pump going bad etc)

 

yeah same with 5th and 6th gear.

that's what i was thinking .. its not shooting enough fuel into the engine?

 

Has the carb been rejetted? What jet size were used if it has?

 

nope the carbs have not been rejetted.. the bike was sitting for a few years and the carbs were cleaned, and spark plugs changed.

 

and what were the float heights set at?

 

after sitting did you drain the fuel

 

hmm, maybe I read this statement incorrectly

 

Lol ^

 

+1 I am curious also...
