But doesn't it make more sense that if you're running an open carb (no filter) you wouldnt you receive more intake? Correct me if I'm wrong.

Well it was doing this exact thing when I got it, and I ended up Checking if the crank seals were bad and I ended up splitting the cases to change the seals and it ended up being the cases were cracked. I doubt there's any oil getting in there but I could check again.. and I don't think it's the woodruff key just because I've taken the motor part 3 times and still does the same thing. and if I leave the gas cap open wouldn't that have the gas flow faster to the carb?
And yes I ended up messing with the tune and the needle adjustment and it revs healthy now, but it still runs like crap. It idles really healthy as well
Did I read this correctly?? There is a crack in the cases?? Where might this be?? Did you repair the crack?? Someone correct me if I'm wrong but can't the transmission oil can be sucked through a crack into the crankcase causing what would seem to be a rich issue? What does your plug look like??
I had a similar problem with a late 90's blaster, it would start up on the first kick but die as soon as it fired off. Turned out that there was a hole in the in the cases around the crank and it would suck in the oil from the transmission. The spark plug would be dripping with oil.
I'd be looking a the crack, depending on where it is. Put the filter back in, top ends are not cheap!!!
Thanks bud I'll put a filter as soon as possible! And I know what a plug chop is.. there's nothing much to these bikes.. they're sensitive. And I had the right plug all along. Thanks for your help bud< Deep sigh...>
You cannot "figure" jetting. It is what the engine needs. A dozen variables to balance.
Buy the right plug because yours will always look rich. A new plug will show mixture clearly.
Warm it up on the old plug and then put the new in. Give it a full throttle run.
The very base of the insulator will show the mixture. Look up "plug chop" to read it.
You can frig around with all sorts of guessing or get it sorted out in a few passes.
