Re: Carb problem

I have a set of early carbs somewhere but can't seem to find them just now.
I think the screws are under the front where they go into the manifolds.

Re: Carb problem

Yep. It adjusts the mixture of fuel and air.

Re: Carb problem

As Bladeracer mentioned, it is under the carbs in front of the bowls. It takes a D shaped tool to adjust them. Some jetkits come with it, hopefully yours did. What exhaust are you running? Personally, I would start off with some 120 mains, needle in 3rd position (from the top) and crank those mixture screws out about 3 to 3 1/2 turns.

Re: Carb problem

i didnt need a d spanner it was a phillips head screw i used a flat head to turn. i have standard downpipes with a viper race can with removable baffles. it said to use 122 jets and i put the needles on the 3rd position and set the mixture screws to 2 1/2 turns out like it said in the dynojet booklet. cheers jon

Re: Carb problem

I installed the same kit on my bike. I read somewhere that the mixture screw is set depending on what altitude you are going to ride at most. 2 1/2 turns was not enough for me. Through research I read while the bike is running, blip the throttle quite aggresively. If it hesitates or bogs, you need to turn it out more, then repeat. I went 4 turns out and it runs good now.
Of course you may need to play with the needles. If your bike is stumbling off the line or when you roll of the throttle, you need to drop the needles (go up a notch). It's a pain is the ass cause it's trial and error. Good luck

Re: Carb problem

Do ALOT of plug checks. Got a friend with a faster bike? That is the best dyno on the planet. Do some 4k rpm rollons in 4th or 5th gear and note the results. You'd be surprised how big a difference one notch on that needle or one size different main jet will make.
