My bike is an 01 with 5600 miles, aftermarket fishtail exhaust from PO, white spacer mod with two #4 washers. As far as I know all jets are original.
Idle mixture is set to 3 turns out, using Lancers directions - the idle never slowed as I turned it out so I stopped at three turns. I had the carb cleaned at the dealer in June soon after buying the bike. The petc*ck needs replaced, I was having stalling issues and smelled gas in the vacuum line. I am running it on PRI now, with the vacuum line closed off.
I have always had backfiring when shutting down, sharp drop in throttle and sometimes when shifting as a added throttle. I have accepted this as signs it was too lean and planned to order a jet kit from Lancer when they are available again. the header pipe had blueing and some gold color to it.
Then Friday I took my first extended ride, 150 miles on the slab each way at 70 -80 mph. as an aside, I need to look into a seat mod also
Yesterday morning I noticed that my exhaust had turned gold/brown, which I have read is a sign of running rich.
I am confused and not sure what to do. Is running the bike on PRI a problem? I have an ebay petc*ck to replace the current one, but I didn't think that would be a big deal if I waited till riding season is done. I noticed mileage has dropped from 55-60 to 50 or so. but when I do this, I would like to get the carb tuned correctly, but really don't know which way to go with it.
Any suggestions?
