I’m hoping someone can give me some insight on this. Bought an ‘01 CBR F4i about a month ago, it’s a bit of a project but have pieced it together over the past few weeks so now just working out the kinks.

I’ve got 2 issues that I can’t figure out:

- 1st gear has recently become jerky (Not my throttle control, I know how to ride &#128514, it’s not quite an ON/OFF feeling but I feel like I can feel the front sprocket through the pegs but unsure of what can go wrong with those

- 2nd is a hesitation in power, in ANY gear, below 3k RPM, picks up just fine after that

Any help is appreciated!

 

Not exactly sure what u mean by first issue do you have a video?
have u done valve adjustment and throttle body sync?
