honda crf 150r clutch problems

hi

 

I have a honda crf 150r for minimoto

 

we modified the engine with

 

cylinder works 159cc big bore kit

 

fmf megabomb - powercore4

 

boyesen quickshot3

 

Suter slipper clutch

 

 

this winther we mounted the big bore kit and new Prox clutch plates including steel plates

 

but the clutch is slipping as f.ck

 

first we tried with the big diskspring 1700N... had no difference then we tried some different oil.... no difference

 

i talked with some friends of mine and they had no problems at all, and they are using the stroker crank to!

 

 

no parts worn out i think we tried everything but its still slipping

 

last year i had no problems at all

 

do you guys have a guess whats wrong

 

im waiting for Barnett clutch plates and a diskspring about 2400N

 

do you guys have experience with Barnett plates?

 

 

 

kind regards

 

Thomas

Hey make sure you are using motorcycle oil, or dirt bike/Atv oil. Anything but car oil. The additives inside of the car oil not only destroy the clutch but obviously make it more slippery

also try adjusting your clutch cable to make sure that there is at least one eighth of an inch of play on the tip of the clutch lever. If not then the clutch will be in semi engage position which is also bad for the clutch.
