Finally getting round to fitting my FCR-mx carb that I picked up cheap (£20). Carb came off a 2007 yamaha wr450. Was planning on purchasing from jets r us but they didn't want to send to the UK.
I searched online to find a baseline jet setup and finally decided to buy the following.
needles OCEMN & OCEMM Was looking for a OBDVR needle but couldn't find one.
main jets I have 175 , 178 and 180
Main air jet 200
starter/slow jet 85
carb is already equipped with a 100 idle air jet, but have a adjustable one as well
Pilot jet 45
I have also purchased a merge adjustable leak jet due to this carb not being drilled for a leak jet and an extended fuel mixture screw.
Seem to be a bit of confusion regarding the knob and cable on the carb. Will be running a push pull throttle but when I asked about the other cable they said it was a choke cable. But online they say it could be the choke cable or the hot start. I personally think it's a hot start cable and the choke works off the pull knob on the side.
Anyway, once I start working on it, I may snap some pictures. Want to get this done as I want to start making some new panels for my bike as the originals have been attacked by UV and they look terrible.
