iTeach Posted July 8, 2020 Report Share Posted July 8, 2020 (edited) Hello, I recently got an engine from a pothead for about 800 bucks. The engine is stock, and it’s missing reeds, intake boots, spark plugs, clutch disks, and a kicker. I want to rebuild this engine and make it a sleeper. My main priority is reliability. I’m leaning towards a 421cub. But I’m one of those guys where I ride really hard, I’m full throttle in every gear. Therefore, I need a setup that’s conducive to my riding that won’t break down on me when I’m in the trails. I recently contacted HerrJuggs. Has anyone ever used them? What engine building company would you recommend? Edited July 8, 2020 by iTeach 1 Quote Link to comment Share on other sites More sharing options...

ginger Posted July 8, 2020 Report Share Posted July 8, 2020 Redline, and Fast are both really good. Herrs i have heard mixed reviews. 1 Quote Link to comment Share on other sites More sharing options...

iTeach Posted July 8, 2020 Author Report Share Posted July 8, 2020 I’ll look into redline and fast. I may simply do a 4 mil with stock ported cylinders, cool head, V force reeds, stock carbs and Toomey Pipes for this. What do you all think.

moneybags Posted August 6, 2020 Report Share Posted August 6, 2020 I've used both F.A.S.T and Redline. Hands down the best your going to get. Forget the rest, Fast and Redline are the best. Quote Link to comment Share on other sites More sharing options...
SandSlingerOR Posted August 6, 2020 Report Share Posted August 6, 2020 Fast Racing - Red line - Driveline can't go wrong with any of those. Quote Link to comment Share on other sites More sharing options...
