Initially my injury was about serval cylinder, thinking back don't think I would even try the new cheetah p/v cylinder. On the road 535 cheetah could chomp though super unleaded at 10 miles to the gallon . Set up as is now 5 gallon tank can see 80-90 road miles

Time wise that works , we have approximately 8 to 10 weeks before weather turns. Have cpi given release date for new p/v cylinder ?

This season the aprilia banshee has been my go to ride , the turn of speed from 40 mph to 130 mph is amazing . Probably say I'm cheetah shy after last attempt Very pleased with the set up as is, but was curious if serval 521 was tried and tested for more.

I've sent email to Redline Are there any other engine tuning companies that could supply ?

I tried posting picture on this site, picture to large for your system. That dyno graph represent ported cylinder or out the box ?

Yamaha rz250 10mil stroked bottom end, white knuckle racing 68mil conversion on original banshee cylinder, 465c.

I've road registered aprilia rs250 fitted with white knuckle racing 465cc bog cylinder engine that mike built. Makes 90rwhp 50 torque Been ultra reliable and very quick. Ive built bike 10 years ago now looking for bit more power . What could I expect swap top end for ported 10mil super serval 72mm cylinder or any other ideas much appreciated.

Putoline RS959 Pump or premix Came recommend by guys who race 250 gearbox karts
