New Year – New Project

Elemental bits of a Velo KSS grass-tracker

Elemental bits of a Velo KSS grass-tracker

Out at Team Mork workshop the KSS grass track machine is roughed out frame fittment-wise, foot peg placement, forks and wheels set up, fenders mounted and seat and tank attachment welded into place. Now its time to get cracking on the internals for the prime motovator! So down to the elemental bits for the engine, gearbox and primary.

Off with the head says the red queen and as it is written so it shall be done. Valves look serviceable but will be replaced with new and new guides. Seat pockets are acceptable with a little shaping. Piston is high dome and much work has been done to make it fit and light. .020 with .008 clearance in the bore. Cam is marked K-17 1 with normal wear and rockers to match. A few less fins on the jug but the bore looks good. Rod and crank look to be in good shape with .004 side play at the big end and no perceptible up and down play. Double row roller on drive side and single on timing end.

Timing case needs to be welded up where broken across lower mag mount stud. Probably why KTTs have base mounted magnetos.

So far we are pleased with the over all condition of the bits and the way the project is moving. The team Captain is confident we can have it painted, together and running for the Clubman’s show in the spring and out to Willow for some hot laps at the 2015 meet.

Stay tuned for updates and news.
