so, im back on the MX bikes...i scooped this 07 ktm450sx for pretty cheap and its very stock, and in good condition. i rode it about 15min after i got it home, and fuel starts leaking out the bottom of the carb. 2 weeks prior, my buddies 06 with very similar carb if not the exact same had a bog issue. his turned out to be a diaphram in the accelerator pump had rotted from sitting up with fuel.
this got me to thinking, should i just burn about $50 and completely go thru my carb since mine seems like it would be a needle seat/float issue. and also,l i though maybe this was cause by the 10% ethanol in our tx fuels and sitting up.
can this be resolved by running straight race gas (100+ octane) or is just a silly issue from sitting up and inevitable from age of the bike.
