complete dune ported topend


Recommended Posts

These are the cylinders ive been working on the past few years during my foray into porting 2 strokes. They run very well. It has been to the last 2 bhq rides and snake hunt.

 

190* exhaust with the transfers staggered from 130 to 128. Angles mostly stock. .020 base gasket

It has a stock head that mull engineering cut to match the porting and runs on 91 octane.

Timing is set at +3.

 

It is highly recommended to run this head or if you prefer a coolhead to have dome cut for it. Its a running topend but needs at least pistons if not bored as it has piston slap. Compression is fine. Current bore is 64.75.

 

You will get the cylinders, head and pistons. I can also make the buyer a deal on ported stock reed cages with boysen reeds and low hour stock intakes.

 

Asking $300 or reasonable offer. I dont respond to bs offers. not really interested in trades but will consider them.
