Well I couldn't call 'em Zerodefect motors 'cause all .21 ABC 2 strokes are defective by nature. I'd get sued for false ad.
Need somrthing german sounding........
Zirgoplatz Engine Inc.
A billet block would be tastey, even if it was just a gimmick, eye candy. Still alot of work. I could make toe plates, top plates, delrin bushings, for the top 5 cars out there for the same R&D. I'd use real hard annodizing to. That real hard, ugly, gray-green stuff.
Whoever makes a 4 stroke convo kit for say $200-250 for the O.s. .54, say for truggies would have something special. Or even better, the lighter more powerful Saito.
We could use a good 3-4 port turbo head, turbo crank motor. $300 is the majik fiqure for race engines. Not too cheap, not too expensive. Not exactly big profit either.
1. Build engine
2. ??????????
3. Profit!!1!!1

but I'm not feelin' good about the block and crank case being seperate. 
Getting the sleeve seat milled square to the bottom of the block will be tricky and holding a consistant tolerance (from engine to engine) between those two surfaces of the block & the distance from the crank centerline to the block seat on the top of the crank case is another issue. With +/- .13mm (metric) tolerance being the norm for machining in the EU ... that could mean a total variance of .010"(inch). For me 6-degrees (.21) 8-degrees (.16) of port timing variance from engine to engine is a lot to give up for the privilage of machining an engine in place of casting (and that's an engine built w/in tolerance
). But, that's the way it has to be done if you CNC the block & crank seperate.
