Big Bore Kit (240cc) for Yamaha Blaster

This is for a complete Yamaha Blaster YFS200 72.00mm big bore kit made by Vito’s Performance. This is a bolt on kit, that has shown proven dyno results of 34hp or more! This has high performance port timing, triple exhaust, and four intake ports!

This kit has been on the market for a long time, and still reigns as KING for a reason: HUGE power gains and awesome reliability.

Beware of other big bore kit that are only 68.00mm (stock jug bored out), this is the true 72.00 kit, with more room to bore out.

This can be used with our 3mm stroker crankshafts as well for even more power (the cases do NOT need to be machined for the crank to fit)
