(Newby)Startup trouble polini e50 j.c penny pinto, need ideas?!?

Hank Aguinaldo /

After i pedal start the bike lights come on, but once i go to throttle it just cuts completely off? Any ideas what could be causing this? Heard it could be poor oli/gas mix some say jet could be clogged?

More history of previous owner setup, was the engine seized before, what's the what timing, carb, what jetting,

Usually if you don't give no answers you don't get no answers, give no info or poor info you get the same because we can't guess.

Bing 14 carb, dont know current jets

Re: (Newby)Startup trouble polini e50 j.c penny pinto, need ideas?!?

A 14 Bing/14-intake 222 atomizer 24 slide 70 jet will run but 15 Bing is better...

No 70 jet in 14mm bing more like 76-80 jet, 222 atomizer when running a a 14mm bing. Polini reed kits needs a way bigger jet and a rich needle

Mine's ok with a 74 jet in a 14/14, I think 70 might be a bit lean at sea level.

14.14 Sha is not a bing carb that has a needle

It jets different usually less then a bing and I'm not even sure if dellorto Jets and bing a Jets are the same

Jet size chart

Re: (Newby)Startup trouble polini e50 j.c penny pinto, need ideas?!?

yeah sha sizes are bigger than bing by a lot.

i start tuning 14/15 bing polinis at 96 and work my way down. think i've got 92 in my current setup? fat and happy with a chincy china air filter.

E50 polini with estroil pipe and 15mm bing, #2.17 atomizer, I jetted in at #90 jet, #24 slide, 2 ring needle, one clip rich on needle .

E50 polini with MLM pipe and 15mm bing, #2.17 atomizer I jetted in at #92 jet, #24 slide, 2 ring needle, one clip rich on needle ,

Za50 polini with estroil pipe and 15mm bing, #2.17 atomizer, I jetted in at #88 jet, #24 slide, 2 ring needle, one clip rich on needle.

Alternate jetting running a #222 atomizer in a 15mm bing for additional gas cooling with same setups as above jetted in at #84-86 jet but required holes in the slide for the engine to idle.

I meant 14 bing/ 14 intake, I'm not talking about SHA's

Re: (Newby)Startup trouble polini e50 j.c penny pinto, need ideas?!?

Pretty sure this is Calvin's old pinto but de-radified.

Make sure you got plenty of gas in the tank and its on and flowing into the carb bowl mang.
