375hp banshees Posted April 23, 2020 Report Share Posted April 23, 2020 Your best Bang for your buck is a port job on your oem cylinders & get crank welded. speak with a Reputable builder, tell them what you're racing against, And how else you plan on riding...done Quote Link to comment Share on other sites More sharing options...
Keno Posted April 25, 2020 Report Share Posted April 25, 2020 Ok?Just to clarify, stroke is how far up and down in the hole. Bore is how big the hole. But yeah, i agree with above, get it ported, or ported for a +4 stroke. Talk to a builder. Quote Link to comment Share on other sites More sharing options...
TheBull Posted April 25, 2020 Author Report Share Posted April 25, 2020 Thank you that's helpful so a stroker motor will have more torque or more horsepower? Quote Link to comment Share on other sites More sharing options...
375hp banshees Posted April 25, 2020 Report Share Posted April 25, 2020 Yes, but not enough to out run you buddies, if doing that alone. usually gets some bottom back thats lost when porting for topend. Porting can more than double your hp. ( if you go all out) but you'll loose most of bottom end to do it. You need to decide before porting if you plan on stroking in tho. If you port it with stock stroke, then decide later to stroke it, you'll have to get other cylinders ( depending on how aggresive you go) when you do that. The port timings will be off. If its just a mild port you might be able to change port timings enough & get cut domes to make up for the 4mil. Stroke & keep same cylinders. And you can't just put in a stroker crank, with out getting port timings matched ported in your current cylinders. When you say race with your buddies do you mean play racing or @ a track all the time? Also if @ a track you'll want to see what class you want to fit in, & build accordingly.

TheBull Posted April 25, 2020 Author Report Share Posted April 25, 2020 I will be on asphalt when racing mostly but just with other buddies that have a little money in their banshees. I also will be trail riding so I just want something mild but not your average banshee either if that makes sense. I'm thinking of the 421 big bore kit. If I do go that road do I need to get new crank also. Quote Link to comment Share on other sites More sharing options...
375hp banshees Posted April 25, 2020 Report Share Posted April 25, 2020 Yep & dont get an ebay kit & i'd stay away from vitos & bp also.What do the others have done? Asphalt as in street or track?Honestly i think you'd be happy with getting your stock cylinders ported & get your crank welded. If you want to go more, i'd look into drivelineSent from my SM-A505U using Tapatalk Quote Link to comment Share on other sites More sharing options...
