He'llo everyone, first time posting in here as I'm new to trialling.
I've got myself a 2006 Rev 3 250, I really enjoy riding it but I've noticed a couple of things.
First off the carb would dribble all the time from the atmosphere tubes so I did the BILLY T mod with the plate tang, replaced the vent pipes with long ones going over the carb.
Whilst I had the carb stripped and cleaned in the bath, I checked the needle to find the rubber hard with a dip in the cone so fitted a genuine needle and body.
The carb also had the standard 30 pilot and 150 main, I've read the I should try the 27.5 pilot and 145 main so I've fitted a 27.5 but I'm waiting on the 145, I've refitted the 150.
Now I'm noticing the bike seems to want to stall easily when I'm slipping the clutch to start moving... This didn't happen until I modded the carb.
What should the basic settings be when rebuilding the carb, what should the air fuel screw be set to, it's set to 1 ¾ turns out.
Also there's a brass overflow pipe under the carb, should the be a pipe on that like the vent pipes?
Lastly, the throttle cable on top of the carb, the metal bend into the top cap, should that be tightened or left loose as I've read something about air getting in at the point and messing with the air fuel ratio.
