drap660 Posted December 19, 2008 Report Share Posted December 19, 2008 Which stroker setup is better and whats the diff between the long rod and short rod as far as performance? Quote Link to comment Share on other sites More sharing options...
dajogejr Posted December 19, 2008 Report Share Posted December 19, 2008 You won't notice a difference in performance from the 110 or 115 rod. What you will have is a more reliable engine...with less stress. The longer rod lessen that angle at which the crank is trying to push the piston through the cylinder wall... 115 is the way I'd go. For stock through .080...you'll need 795 series or "racers choice" pistons. Not trying to be a jerk...but have you thought about the rest of the motor, like porting to match the 4 mil crank, whether you're going to run cut domes/head or a spacer plate, etc?

Wildcardracing Posted December 19, 2008 Report Share Posted December 19, 2008 I'm going to have to agree with dave on this one, the 115 is the way to go. Much less sideloading on the pistons=a motor that will last longer. IMO the best way to set up a 4mil is to run cut domes and have it ported for the additional stroke, spacer plates will raise your durations and be more prone to developing air leaks.

I like the cut head/domes better than a spacer as well... I agree!! Quote Link to comment Share on other sites More sharing options...
tony cub Posted December 20, 2008 Report Share Posted December 20, 2008 (edited) i guess the 1st ? should be what are you going to be doing with this motor?trail riding, track racing or street? reliable is for trails..since you live in the miami area 80% of the time your going to be street racing right??hit me up if you need some help im local too.

Wildcardracing Posted December 20, 2008 Report Share Posted December 20, 2008 You can realize the same power potential from either setup for very close to the same price, might as well go with the more reliable of the two. The ONLY advantage I can see in the 110 setup is that the 513 pistons are available in .010" increments whereas the 795's are only available in .020" increments.

drap660 Posted December 24, 2008 Author Report Share Posted December 24, 2008 I use the bike to trail ride a bit (long cool straights with some turns) Highspeed trails if you will. I dont like tight junjle type trails. The bike right now has a set of wiseco pistons .50mm, 155lb compression with .40 piston to head clearence. Nicely ported cyl's. Bike tops out at 102 with me (260lbs) on it with 16/40 gearing. Alot of locals around here like the short rod setup with spacer, and I have seen them fly, but I keep wondering if I should go with a long rod cause you guys say they are great. I used to be a mechanic at a yamaha dealer here in Miami call R&R jettech. We used to service and repair atv's and jet skis. I have lots of knowledge on any 2 stroke or 4 stroke. I built my banshee myself,porting and all. I have complete access to a full machine shop. I even built a Raptor I had with a 800cc stroker kit and some juice. But, I am completely lost when it come to a stroker on a banshee as far as what works best. The cyl will be match ported to the stroker. Wont the longer rod rev slower Quote Link to comment Share on other sites More sharing options...
