Here's the deal. This past summer while doing some riding foulded a plug on the left side. Normally no big deal, put new plug and go, right. But the next time out on a weed end trip, foulded 8 plugs all on the same side. So when I got back went thru carb (2 into 1 carb) reeds, ended up boring and new pistons and rings crang seals split the cases, basically the hole 9 yards. But this weekend went out and after about a half hour fould a plug agin. Same side always the left side. Check the plugs and the right side looks perfect and the left side is wet. I tried switching plug wires same thing. You can have ti running for 5 mins and tell a difference in the temp of the exhaust pipes. also a lot more smoke comes out of the left side verse the right side. Need help Thanks
