I took my carb off to inspect it and clean the gunk out if it. I didn’t adjust any screws, change any gaskets or swap out any jets. When I put everything back together, the bike started up fine, but was running hot and the exhaust pipe started glowing hot. Any ideas why this happened? I tried to let it cool then Idle for awhile, but after about 10 minutes and a little revving, it was running really hot again. Need some suggestions if anyone has had any experience with this.
