pit bike carb screw adjustments
Posted August 19, 2008 - 10:52 AM
I had a problem with my bike fouling spark plugs, its running to rich and i know its to do with the carb settings. the mixture screw probably needs adjusting.... what i wanted to know is a base line to work with on both the idle and mixture screw.
the carb is a mikuni and the only way to adjust the mixture screw is to take the whole carb off since the screw in on the under side of the carb. (i cant fit a screwdriver between the carb and engine)
i wanted to save time and ask for an average setting please. so i don’t have to keep taking the carb off and probably end up rounding the bolts.
thanks for reading, all help appreciated

makes tuning a whole lot easier. I start with the screw between 1.5 and 2 turns out but thats what has worked for me. Search for a tuning/jetting thread by Precision50. Its a great resource, I used it and my bike runs awesome. Good luck

about the carb adjuster on staggs, does it replace the screw thats already in the carb?

Definitely the screw from staggs is a plus, but until he has more in, you can still get the bike right.
If you go less than 1.5 turns from bottomed out and it's still too rich, you need a leaner pilot jet.

I do not believe it will fit under to work on our Pit Bikes....as I have one that looks just like it I use to tune Preformance Six pack Carbs on this Bad Boy
it may work if the bend is under 1 inch
