Highly recommended, fast, durable. Running an Sha 16, larger reed, polini intake, Le partie cdi.
Base gasket requires a .8-1mm base gasket, added to included gasket to clear ports at bdc. This will allow removal of head gasket, w copperkote. Yielding 1.2mm of squish.. cheers!

Good quality.
Very powerful paired with the doppler head, doppler pipe, small volume stock Teknix cases 3 ports, large taper crank, polini single flat reed, 19mm polini intake, 17 to 19mm carb, a racing Doppler variator ER3, doppler engine spring, malossi belt, motobecane"Le Partie" cdi. Best if you have the extra budget is to get a Doppler clutch pulley for super fast take offs.

oh man, where to even begin with this kit! jeez. the thing is amazing in every way. relatively cheap yet the quality is through the roof. ports are chamfered nicely out of the box, single ring piston is really really well machined.
the porting is agressive but makes power throughout the range.
i have mine on polini race cases, so i opened the transfers to match the cases. other than that there's no porting. im running it with the matching doppler o ring head which is a great setup.
50mph with stock pipe
