Greetings! New to the CRF world, been riding since 1976, first bike Z-50. I have owned, 1974 cr 125, 1982 kdx, ltd 440, nighthawk s, yzf 600, currently own a FZ1 and little red, 2006 crf 150F.
Enhancements:
Power up kit, 108 main, 42 slow jet. I have the other parts but not in, can't seem to figure it out.
FMF Q-4 pipe
Uni two stage filter
My question is: I bought the power up kit, replaced the Jets, had the main 115 in but it was slightly popping and bogging in the upper gears. meaning when I was puting around in 3rd,4th gear I would get on it,it would bog,pop
clutch it get a pretty good midrange pull out of it, but top end seemed to flatten out.
Put the 108 main in, no pop, no bog but not a good pull. I have not yanked the air box open because I like to cross creeks.
Question is: How do you get the throttle spring out to check the clip?
(I believe the CRF store took me for the carb parts, meaning I have two items I didn't need,or are these items necessary to complete the power up kit?)
I bought the whole carb kit, fuel screw and power up needle.
Besides the fuel screw, is the power up needle stock? Again, how do I get it out to replace it?
Where is the fuel screw located? I have the tool to remove it, just need to find it.
Need some help from the motor heads, thanks Dennis
