I HAVE JUST JOINED ORG YESTERDAY.
I HAVE JUST PURCHASED A HONDA FMX650 - 07
I WOULD APPRECIATE AND TIPS ON TUNING.
AT THIS STAGE I HAVE JUSTE REPLACED REAR SILENCERS WITH REMUS SILENCERS WHICH HAS IMPROVED PREFORMANCE SLIGHTLY.
Hi follow these links. the carb mods make most difference after the exhaust and headers. i wouldnt bother with a dyno jet kit as you can pick up a 2nd hand pumper for the same price but they are a bugger to setup. i wouldnt buy a K&N too, just rip off the mesh on the rear of the oem air filter and cut a big hole in the side of the access cover on the airbox (on the unfiltered side of course!!). just do these mods and you will be happy with the power increase.
as the previous post, the next step is reprofiling the cam, kent cams do this for about £70. then you can get head work done, skimmed, inlets straightened etc etc,,,,
these are for a XR650, BUT ITS THE SAME ENGINE
