cmoore14 Posted June 2, 2017 Report Share Posted June 2, 2017 Just bought a 1991 banshee and I wanna make it a trail bike but I want it to keep up with the 450s. It already had fmf fattys , vforce 3 ,stock carbs guy I bought it from said it was jetted correctly . What kind of port job would be best for me & would I need any other mods Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted June 2, 2017 Report Share Posted June 2, 2017 If you're gonna take it all apart to port it, you might as well do a full tear down and do a +4mil stroker crank. Get the crank porting and through a site sponsor who is a shop so it can be welded. A trail port would be a good start. Definitely get a cool head with custom domes made for your specific set up. Whoever ports it should also be able to do the domes. Also, look in to a timing plate. A few degrees or more can net a good gain. You could always upgrade the pipes and carbs down the road.

SandSlingerOR Posted June 2, 2017 Report Share Posted June 2, 2017 I agree with the last two guys. If it runs good, leave it be for alittle bit and dump your money into suspension and tires and wheels. Also handler bars, steering stem and steering stabilizer. Stainless Steel brake lines is also useful.. hmm what else? Quote Link to comment Share on other sites More sharing options...

bigweav81 Posted June 2, 2017 Report Share Posted June 2, 2017 Trail riding all you plan on doing? I'd imagine slp's would shine on a decent trail port if it's tight woods riding. Sent from my SM-S820L using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...

My buddy has almost the exact same set up right now. vforce 2s, fattys, stock carbs with clamp ons, timing plate at plus 4, and he just got his cylinders bored and an aggressive trail port by Driveline in Michigan with a modified stock head to run interchangeable domes. Depending on what your budget is OP it only costed by buddy around 500 bucks to get his cylinders bored, ported, and head work with domes and pistons. Will still be making decent power with a stock stroke. Quote Link to comment Share on other sites More sharing options...
