Bayou 400 crank but no start?

[Kaj Colum]

Pushing the start button the engine turns and will forever without starting. But if I use the kick start it will start with one or two kicks everytime, any idea as to what is going on. New good battery and coil, I'm ready to try anything. It's a great bike, but this is getting anoying. Thank you.

Does the engine turning over have enough speed or is it a slow crank ? I’ve seen starters that crank at a low rpm and that won’t start the bike.

Hi Frank, To me it seems to turn fast enough, but I have ordered a statrter just in case, wondering if it could be anything else though.

[Frank Angerano]

As long as you have consistent spark verified while it cranks and fuel is going into the carburetor then it could juts be a cranking issue.  It usually happens when you have low compression.  I would take a compression reading for sh*** and goggles.  

[Kaj Colum]

Yes, I was wondering about that. I'll have to borrow a tester and give that a go. Do you know what the compression should be? thanks.

It’s in the spec but minimum should be 90 lbs.

Ok, thanks again.

Let us know how it goes.

Hi Frank, Thanks for your help. You were right it was the starter was weak. I installed the new starter today, it works perectly! I honestly forgot what it was like, now I barely have to touch the button and boom, she's running and raring to go!
