Remove the anti-smog cannister and blank the resultant holes...then do your carb jetting.Hi guys, I bought an FMX 650 ....Any ideas to what I should do with regards to setting up the carb and jetting? Not really bothered about massive power gains, just want a smooth ride. Thanks.
Is that the tutorial to do it? http://www.xrv.org.uk/forums/dominator-fmx/44310-fmx650-smog-pair-system-removal.html and what does it help with? Also any ideas on jet sizes? I see that you're from East Yorkshire, do you know of any places to get the bike jetted and set up?Remove the anti-smog cannister and blank the resultant holes...then do your carb jetting.
Also ensure valve clearance are on the "loose" side of the spec.
Thanks a lot for the hint, I'll be swapping the pilot jet to 55 and adjusting the jet needle on Tuesday probably, do you happen to know where I could get some washers in the Hull area? Also I'm a newb to carbs so hopefully I will be able to work out where to put the shims, but would be great if you could give me a hint? I've attached the image with 3 possible positions (might be totally wrong). Also, from reading other forums about the XR 650 I see that the shims have to be big enough to raise the needle by 0.5-1mm? Also I doubt that you'll know off the top of your head but what sort of diameter should the shim be? (inner and outer).And since the needle jet is not adjustable, you could try shimming it to raise it slightly
- very small quality washers can be used
Answering my own question for the next guy, no, 13T sprockets are not available for the FMX650. In the past JP made 13T sprockets that did fit, but those were thin and likely to damage the counter shaft.I have a 2007 FMX. I was not impressed when I got the bike but after a full exhaust and Daves mods it feels like a different bike. Thanks for the info guys:thumbup::thumbup::thumbup:
I want a little more snap though.
What is the biggest rear sprocket one can use with the stock chain?
Are 13T front sprockets available?
