END OF SUMMER SALE! Kick it up a notch with the bolt on power pack top end from Jakes!

Bolt on power like no other! Proven to blow away the Fred-head products.  This Complete kit will work on any 66cc engine, so please specify which manufacturer when ordering!! This Kit includes Jake's Jug ported cylinder, Cut-on Piston, A race proven High Compression Diamond head,  Jakes hog snout intake, Mikuni VM-18 carburetor and gaskets. We have chosen The Mikuni for the quality &  reliability. Solid reliable and smooth, delivering much more bottom end torque than the smaller 14 and 15mm carburetors., this is the right choice. Tuning a Mikuni will require some reading on your part but once you have it dialed in for your area and temp, you'll be very happy. We've found that this is the happier-customer-version. It comes with a .070 main jet, and a .030 pilot jet. Here at sea level in the 70*'s we have found that a 65 main jet and 25 pilot jet are the right combo. you will get these with your order. 

A la Carte total of $350. You Save $$$!

* If you have a Grube engine please specify. You can tell by the piston pin placement. Grube pistons have the pin at the 1/2 way point. centered top to bottom. 

ohter engines have the pin low, just above the transfer cut-outs.
