Carburetor Cleaning & Tuning 101

When it dies open up your gas tank and see if its venting fine or not. Maybe a kinked line under the tank. That's what happened to mine. It would be fine for the ride and mid way through BAM she would shut off and choke would have to come on. With this it was getting to much pressure build up in the tank. Found the kinked lines and it was good as new.

Oh and about the pilot screws, they effect idle and pretty much just initial throttle roll on. Jet needle effects mid range power, main jets effect upper rpm power. Technically, jets don't effect power, they effect air/fuel ratio. In a way I suppose it effects power because if you mess up the ratio, you will lose power.
You would need to adjust them equally. If nothing it wrong with your idle or roll on, then I wouldn't mess with them.

Ex: all 1.5 turns out.
Thanks!

i have another question. is there a cheap carb sync tool i can buy. i dont want to make one because i want to do it right the first time. the cheapest i can find them are 90 bucks? for some tubing and liquid!!! another thing. my bike has alot of power in the low rpm range. i can hammer it and get going but after a certain rpms the power lets off. i kno the power goes back down after really high rpms but mine seems to lose a bit after 8k would this require bigger main jets?

Your bike should pull very hard and smooth through all the RPMs. Even at 12+ when your power band weakens, it should still feel strong and reliable, without hesitation or sudden drops in power. You may need smaller main jets, OR bigger ones. That is for you to test out. air/fuel needs to be the perfect ratio for your bike. If you are getting less air, then bigger jets like you suggested would only throw that ratio farther out of whack.

The rare times I come to cbr forums to see whats up, I always check this thread out. I still can't believe someone went through that amount of effort to write up a perfect tutorial.
The only sort of experience ive had with this business is a little bit of nitro rc toys a few years ago. Just last summer, I took my laptop out to the garage and totally corrected my 5 rpm stutter. I know ill be doing another thorough carb clean this spring considering I accidentally put a little bit of diesel in while rushed to class. lol
Thanks a lot, Dissevered

I got one off eBay brand new for about $50, that doesn't seem too bad. Make sure you get one with 4 guages, or you're gonna want to hang yourself.
