This is one of Duncan`s top end kits. They have been making them for awhile, and updated the cylinder a couple of years ago. This is one of the newer updated versions. This cylinder has had extra port work and polishing and re nikasil coated recently. Basically it is like new and better than new! Included is a like new just broken in 68mm wiesco piston with clearances set at .0025, new 21cc dome included. Requiring 100 octane gas. A 19cc dome would be needed if you were wanting to run straight race fuel. This kit sells for $1800. from Duncan and is the best made! This will beat the new 4 strokes with no problems!
Motor was broken in nice and slow, completeing many heat cycles before running hard. Several idle sessions in driveway, several short rides, and periodically increased time and aggressiveness to break in well.
This makes strong power throughout the powerband!!
This is priced to sell quickly.
$799.00 shipped
I also have a DUNCAN PJ37 Carb with new cable $115. shipped
