Looks Lean/70ccE50

Troy Brown /

Set up. 70cc with head, biturbo, 14intake, 15bing,aftermarket bing filter, 81jet, good point& spark. Wont start unless i use starter fluid, even then it takes 7-8-9- hard kicks. any sugestions?

Re: Looks Lean/70ccE50

hard to start usually equals low compression, or weak or bad spark

Re: Looks Lean/70ccE50

check your timing

check your fuel delivery

Everytime I have had a bike that would only start with starter fluid, it has been a fuel delivery problem.

I'm not saying this is the case with yours, and I'm not saying this is the case _everytime_, I'm just saying.

Will check tomorrow. Would the 81 jet be to small for this setup?

Re: Looks Lean/70ccE50

probably not so lean that it wouldnt start
