Hi y'all!
After grinding my OEM 90 cc crank (and 54mm piston/jug), I find that Parts for Scooters no longer stocks standard 90 cranks! Ouch!!
Are there any folks who stock pin/rods for these? I notice that the BWS 100 uses a 14mm wrist pin; mine is only a 12mm. Heck, if I
knew it would fit, I would use the Naraku crank and matching jug/piston together. Anyone know the differences between my long case
and a BWS/Aerox 100 motor internals/peripherals, like shaft splines and sizes? I would ideally like to use my crank wheels and just
replace the rod and pin(and rollers/spacers). Seem to remember someone selling sets here or abroad, but too long ago. Any help is
appreciated, guys. Thanks

Ebay search for Polaris Sportsman 90 crankshaft,usually some good stuff there..Pro X 03.2001 is a close fit,but none available..Will dig around and see if others will work and report back...

Your lucky that there is still support for even the 50cc engines.. It's almost a decade since the heyday of scooter tuning has passed, I mean there is plenty of gear I'd like to buy for my Aerox that is no longer produced and many of the stores we buy from are just stocking the tuning items they are able to get in now.
