I put a E50 together using a 70cc kit for a A35 I had lying around. It idles fine but does not accelerate at all just bogs. Has a mikuni vm20 first jet was a 120 dropped down to a 90 no change dropped to a 60 no change. I moved timing around and still no change. Any help would be appreciated.
does it rev on the stand? do reeds look ok?
Targa seat/tank on that korado frame is dope btw
I am going to guess that you have an airleak, combined with poor compression
This remindes me of something stupid i did, changed the Jetting around a ton and didn't notice any change at all, put the Piston in the wrong way so that it spit out gas into the Exhaust.
if 120 main to 60 main theres no diff. it might just maybe be a clogged atomizer, clean and run some filters.
It revs awesome on the stand. I noticed it smokes quite a bit could a bad oil seal on the clutch side cause that?
Thanks. I didn’t like the way it looked stock and had all the parts in the shed.
Your Vm20 should have a ~145-175 jet in it. 90 is waaaayyy to small. If its acting unusually rich and leaving heavy/thick white smoke it needs an oil seal.
Second upjet. Sounds like lean bog. My vm20 e50 has 170 for the cold season
Checking timing then leave it!
Is the piston correctly installed?
Try a new spark plug
Flue delivery
Kill switch wire short
Carb dirty
Huge fucking air leak
if it doesnt have any power have you tried plugging it in
