2004 with Yoshimura slipon, K & N filter w/no lid airbox, jetted but I don't know what size needles.
Heres my problem. The bikes runs great at sea level. I went riding in the hills 4000/5000' elevation and it ran horrible. Sputtering, backfiring, flooded basically rich. When I got it back home (322') it ran ok but I could feel heat pouring off right side of the engine like I never have before.
I took it to a shop and they replaced the "thermo switch" and I replaced the radiator fan. I can feel coolant surge in the hoses when I rev the engine so I am assuming that the water pump is working. I have never seen or heard the radiator fan old or new kick on.
When I start the bike up it runs/idles fine for about 3 to 5 minutes and then dies. I can feel heat pouring off of it (still) and I can not get it started unless I choke it. Once the bike has cooled off it will start up fine with no choke and then heats up and dies.
Before I send it off to another shop for some more trouble $$$ shooting, any ideas on things I can check on with my limited mechanical abilities. I have tried searching for similar problems but haven't seemed to find any posted. I have been impressed with the knowledge in this forum and eagerly await any assistance offered.
