Hi bud, it should have a phbh26cs carb on it, which i think run a 135 main jet, and 46 slow jets standard i think?

I would check the oil levels in the folks which should have about 360ml of oil in each leg, not sure if the carb you bought will work?

Im sure some one else can help out. fingers crossed mate

I would think the PHBL should work fine, as the later ones used it as I recall. It is a simple carb and may be better than the PHBH in simplicity alone. Insure the fuel inlet(banjo)screen is clean. The round thing!

Even off a GasGas, they all run similar jetting. I would think your pilot jet should be something in the 33-36 range, and the main jet in the 115-125 range. Needle clip in the mid range, the bike should run ok, with small changes depending upon your fuel.

Be sure the jets and small passages in the carb are totally clean, and adjust fuel screw (1.5-3.5)range, for best response.
