Does anybody know offhand what the correct jetting would be for a crf70? or mebbe a crf100??
Or any aftermarket pitbikes in the 70 to 110cc range?
My son's chinese 110 seems to have developed a slight problem.
You can ride it around at part to half throttle all day no problem. But when you hold it wide open for more than 5 to 10 seconds it shuts down.
It sounds like it ran out of fuel. But i cleaned the carb out, checked filter & fuel line, tried fiddling with the float settings, but it still shuts off after a few seconds of full throttle.??
After it shuts down it takes about6 or 7 kicks and it fires right back up, sputters for a second & then runs fine.
Im thinking the main jet is too rich, and combined with this awful heat & high altitude might be flooding it out.
Any opinions?
Oh and PS: the jetting is now primary/idle= 32 , main jet=75.
(sounds kinda lean to me though.)
