Hi folks, I have very nearly finished the re-build of my xr600r engine (wiseco 100mm piston, hotcam, new rod etc.) with only the valves to set and the wiring to plug in. I've just gone to fit the FCRMX (off crf450) and the tank is fouling on the throttle cable housing on the side of the carb, I might be able to get the pull cable on but not a chance of fitting the push cable. I've read up on it so I knew this was going to be an issue. The common solutions appear to be: Heat up the area of the tank with a hot air gun and re-shape Tilt the carb away from the tank at the top Now I tried heating up the tank to re-shape it, but all I managed to do was soften the top surface of the plastic, then I got scared I really can't afford to melt through the tank. Plus I'm worried about making the plastic brittle. So I tried tilting the top of the carb, this could work but how far over can you go before it causes running problems? It certainly doesn't look right. Failing this is it a bad idea to just use the pull cable? Help me before I go back to the original carb!
