Anybody know how much difference there is between a 5JG 1 (US) carb and a 5JG 2 (European) carb? Bought the 2000 YZ 426 cheap, not running, and previous owner said he broke the corner off the original carb, where the bowl mounts, so he got one off Ebay. It ran before that. He didn't do anything to the Ebay carb, just gave up and sold the bike. I'm just starting on it, with all new jets, needle and seat, etc. but found out the 5JG 2 is standard in Europe. I can't find any differences and am planning on trying to set it up the same as I would the original.
