Default Re: To all of those that have drilled their own jets

I had a problem with my bike a couple of months ago, when it was hard to start and ran very rough. I thought it was a bad spark plug or wire, but after an hour or two of checking things out, I discovered that the four bolts that hold down the magneto had become loose inside the cover, and allowing the mag to wobble around. That was all it was! Take a quick look at your magneto bolts. Another clue would be that you reduced the plug gap to make it fire. That's an indication of a weak spark coming from either your mag, CDI unit or bad plug wire, Take a close look at your plug wire connection to the spark plug.
Change is inevitable and progress is OPTIONAL!

Did you drop your carburetor bowl and check your float and the needle valve? Sounds like you might have some gunk on the needle valve and gas is just pouring into your engine.

unfortunetly my carb doesnt have the needle valve i have a dellortoto sha 16.16 i believe and the only way to control the flow of the gas is threw the size of the jet, other than that i figured out my problem or at least wut i think was the problem, about 3 weeks prior to this incident i bought a Flow and Go wich you hook up to your gas can and you can pump gas into your bike instead of having to lift the can use a funnel and all the fun stuff its alot easier, problem was it siphens gas from the bottom of the canister (4 gallon tank) and i had done my mix when i installed this thing and havent bothered moving the can never mind shaking it so my guess is when i filled up for my long trip i sucked more oil than i should have as maybe the gas/oil mixture had seperated a bit and being full throtle for about 25mph or so i guess alot of the oil sat in the crankcase and eventually soaked the plug and i had no spark that is the only theory i could come up with as there was nothing wrong with the air/fuel mixture or ignition it just simply died and refused to fire back up but was fine after taking out the plug, airing out the motor and cleaning the plug, amyone else ever experience such problem???
