I was working on a bayou 220 a while ago and the key on the cam stripped, thankfully I had another bayou 220 engine on hand.

I also got a generic mikuni carb off of ebay for $80ish. It was a 26mmm size though not a 22 (or whatever the stock size is) with a little tuning it worked fine.

Does anyone know the ring end gap specs? I'm getting ready to reassemble the motor and should probably check it before I put it back together.

 

I've got the service manual. I'll try to update post with that in the morning.

 

Thanks. I'm going to buy a repair manual ASAP.

 

The piston/cylinder clearance is: 0.025 - 0.052

piston ring end gap
top: 0.15 mm - 0.35 mm service limit: 0.7
bottom: 0.30 mm - 0.45 mm service limit: 0.8

I'd upload the page that has all the specs, but I don't see a place to do that.


*edit*
*I actually have the bayou 220 manual, but I'd assume they're in the same ball park. at least the service limit.

 

fyi, if your getting a manual, I got my 220 manual HERE. there like 5 bucks.

 

End gaps for the 300 are .2-.35mm, with a 0.7mm service limit.

If you do not replace the jug, make sure you hone the cyl and clean
thoroughly with soap and water to get all the grit out.

 

Thanks everyone. I got it back together about a month ago and it seems to be working great but I have only put around 6 hours on it so far. It seems odd to have it not smoke and burn as much oil as it did gas. Lol.

 

why couldn't a guy put a mikuni (you know a carb with a cable operated slide valve and metering rod system) from, a bike or sled on this and toss the pos oem carb in the garbage??????????????

 

I've thought about it, but aside from the diaphragm failing, the OEM carb works great and is good on gas. Hondas and Suzukis use the same type of carb so they can't be that bad.
The old Bayou is still working good. I put over 100 miles on it on Saturday with no issues at all and burned less fuel than my brother with his 2004 250 Bayou.
