[ntula]

in case i have the worse case.. .what carbs fit which m900... part number...

i may need to swap carbs on a '99 m900s

I don't know part numbers, but the 904 motors always came with 38mm vaccuum operated Mukunis. The hot ticket (if you can afford it) are 41mm FCRs.

Yes, FCR 39 or 41.  I have the FCR 41 split singles on my '99 m900 and they work great.  Need to adjust the cable for syncing the carb but what a rush.

I have the original Mukunis carbs for sale if you what those.  I'll sell em cheap if you go the OEM route.

Let me know.
