410 stroker motor

[shawn941]

i just bought or put on layaway i should say, an 89 banshee that has a 410 stroker motor in it. i bought it from a used cycle shop for $2250. all he knows is that it has a 410 stroker motor in it, i looked at the carbs and it has keihin carbs on it,not sure what size they are. i guess what my question is i know a stock banshee comes with about 43 hp stock,,,,could anyone tell what this 410 might put out and what kind of horsepower? and it obviously would have been ported? any replies appreiciated

Hmmm...could 410cc's be a 4mil or a BB stock stroke? I would Guess 70ish without knowing all the details.

Banshees do not come with 43 hp stock.

Banshees are 37HP stock.

Depends on every thing you have. Who did the porting and what type? That would be the biggest part of how much power you would see.

 

Also timing, compression and fuel type too.

if its got a stroker crank with no portwork and bolt ons, it could be around the 45-50hp range.

 

however, if its been ported, depending on what type of port work and the builder, it could easily have over double the stock hp.

That's what i was going to say. Portwork will make or brake it. With the right set up, it will be a very fun bike. I wouldnt focus on #'s but just look over everything and make sure she runs in tip top shape.
