Now Selling 52mm Bore 85cc Kits! Phantom Killer

[sherron82]

Thanks for the link. I see there is a post that Grubee will also sell this engine,
and there's one post by a user having trouble tuning the engine, but overall,
the engine looks very promising.

I've purchased a avenger and have no issues out the box so far. On my second tank of gas and the engine runs like a beast. I am going to purchase the windowed piston and a reed valve set up soon plus the head and exhaust, should be a absolute killer then!!

I'd save your money on the head, honestly, unless you just really want the looks.
