200cc roost havoc twin :devilish::love::love::love::love: thing is probably scary fast on a drag scooter. i definitely want one of roost havoc's 70cc cylinders if/whever i replace the athena!! rated for 30hp. would need a radiator (cuz its an water-cooled cyl) but thats not that big of an issue.

That engine needs some tuning and an Airbox. Did you noticed the gas vapor when on the throttle, an airbox would help that . Z you want to be impressed. Here you go, Honda NSR 500 some say it had 200 hp out of the 500cc 2smoke . I loved watching these bad boys race . Complete animals.

The guy said it was still being tested and tweeked, not finalized. That ns500 is a beast ? such a snappy throttle response ?

If they are lucky they might get to 100hp but I kind of doubt it.
I really hope you meant Tweeked. I don't want to see an engine twerking. I don't think it would be pretty.:LOL::LOL::ROFLMAO:
Woah why in the hell did my auto correct go there ??‍♂️???? and yeah I mean tweeked (just did it while writing that) not twerked ??
