:banghead rode my bike 2 miles from work to home, and noticed a gassy smell. lookin' around i noticed the right pipe, rear cylinder, had really hot air coming out and the left one wasn't hot at all..... this was after i turned off bike. recently had the tb's synched and tps done. didn't notice the heat or smell for over a week after. also noticed after the synch and tps, the fast idle cable doesn't get the rpm's up as high as it used to. any ideas where to start? plugs replaced, new air filter, new oil. oh, i also let the battery run all the way down on accident just before this happened.
