I have a 2000 CR125 with a new PWK 35mm carb conversion, stock exhaust, pretty fresh motor, and Rekluse auto clutch.
I swapped out the Mikuni TMX carb for the Keihin after having constant jetting problems...now that I put on the PWK I am having the same problems.
I am at about 200' above sea level. I have a freshly packed silencer, clean and oiled air filter, new BR9EG plug, and 32:1 premix with Mobil1 MX2T and shell 93 octane pump gas.
In the 35mm PWK I have:
Pilot Jet - #58
Needle - Keihin DGJ needle
Clip Position - 3rd
Main Jet - #168
The bike runs fine if I slowly roll on the throttle in first, and then runs strong throughout all the other gears. When I crack the throttle WFO from a standstill or even moving slowly it bogs real bad and dies...everytime!
I followed Spanky's Jetting Guide and tried a #55 pilot. The thing is, my airscrew is not having much affect on the idle. I never need the choke to start the bike, but when I do put it on while the bike is running, the idle drops a bit.
I have spooge ALL over the exhaust manifold running down the front of the case, and even out of the top of the cylinder where the plug is (unless it is just splashing up but it looks like it is actually squeezing it's way past the plug which is pretty snug).
Like I said, besides the WFO from a standstill, the bike runs good.
any help is REALLY appreciated!!! Thanks. :cool:
