New hand built motors and kits with front and rear 8mm mounts

Do you sell 48cc 2 strokes?

Hey, excellent service Lee.
As received from another supplier, my kit had some minor quality control and assembly problems that an experienced builder like yourself would not make. Things like fasteners too tight or too loose, too many washers stacked up and piston too close to the cylinderhead. I think you are offering an excellent service to new riders without the skills and experience to know these things themselves, or who are looking for a "plug and play" motor. The few $$$ you are charging are well worth averted disaster.

A couple things I'd suggest (and you may be supplying them already) for reliability:
1) a better air filter. Stock will not handle dusty conditions.
2) better squish area and gap setup. Prevents detonation and head warp. Stock head squish cut to match gasket.
3) port window chamfer, deburr and slag cleaning. Not a porting, but a 1 minute cleanup.

I really think newbies or non-mechanical types should be buying their kid from someone who has gone over it and serviced it for assembly. I see even the assembled engine as a DIY "kit" part that needs to be verified before running.
