| CRF150R Jetting I know some of you may say that this is another jetting Thread..I searched & find mixed info. I'm sure some of you out there feel the same way.....
Just picked it up for my son on Fathers Day weekend (I'm such a good DAD....HaHa)...came in to dealer after the cam recall.....
I have a stock motor, no pipe, stock air filter (with screen). Ride in california 0' to 5500' elevation......Temp now has been about 90-95 deg out....Break in has been done.
Mine came with Stock:
Slow speed Jet: 45 (Yes, 45. might be what they are installing after the cam recall)
Pilot Screw: 2 turns out
Leak Jet: 60
Main Jet: 135
With this setup, it does not bog on low end so much, just a pain to start up when warmed up....it was popping on deceleration, but I set pilot screw to 1-1/2 turns out & it helped with the decel popping.
I here options like this:
Slow speed Jet: 42-45
Pilot Screw: 2 Turns Out
Leak Jet: 50 ------Some don't say to change this, just to stay with the stock 60.
Main Jet: 138
Wire the Acc pump cam (any one have info on how this is done, a picture would be great) I need help on the hot starting problem, as I still have this problem even with the 45 stock slow speed jet..... Any help would be great, Thank you in advance...
