I was just wondering what jetting some of you are running in the 2001 CR125. I have done a search on it and haven't found anything.
Stock jetting is:
Needle- 6BEG20-68 3rd Groove
Pilot- 45
Main 380
Air Screw 2 1/4 turns out
MXA recommends this jetting:
Needle- 6BEG21-69 1st Groove
Pilot- 45 (stock)
Main- 380 (stock)
Air screw 1.5 turns out
Heres the catch, they recommend a 4.5 slide and the stock one is 5.0. I really don't know anything about cutting the slide, and I haven't found a different size to buy.
FMF recommends this jetting:
Needle- Stock 2nd groove
Pilot- 50
Main- 360/370
Air screw- 2.5 turns out
Slide- Stock
Heres the catch with FMF, they say that you need to run 50/50 mix of race/pump gas in the CR125.
I ride really close to sea level, using Motul 800 2T 3oz per gallon with 92 octane pump gas. Stock bike with 50mm cut of the silencer. The bike has very little spooge coming from the exhaust. I have been running stock jetting with the clip in the first position. The bike seems to have a hesitation right off the bottom. I was just wondering if anyone had jetting recommendations for summer and or winter. Summer temps here are 85 to 95 deg with high humidity. Winter temps here are 35 to 55 deg.
Thanks for your replies.
