Wreckless_Rider Posted November 16, 2017 Report Share Posted November 16, 2017 Whats up everybody. Just got my shee put together, everything done is listed in my sig. Running a true stock timing curve with +4 added that i programmed into the dynatek box. So its the same as a stock cdi and +4 at the plate. The bike has arm ripping power once it hits power band and never stops pulling. I love it! But when im riding trails in my 20acres of trees, i always find myself in 1st or in second revvin her up and dumpin the clutch around every turn. Its lacking bottom end. Its my 1st shee, is there something i can add to the build list that will improve its bottom end power but now hurt top much? Or is this just the nature of the beast with dune ported cylinders.

ZillaFreak Posted November 16, 2017 Report Share Posted November 16, 2017 I can't see your sig, so could you please list every mod to your engine and please include the jetting specs too. Also, include what tires and size you are running and sprocket combo. Quote Link to comment Share on other sites More sharing options...

Well it's a banshee soooo..... Buy a 4 stroke. 2 Quote Link to comment Share on other sites More sharing options...
RagunCajun Posted November 16, 2017 Report Share Posted November 16, 2017 I have a big serval and it's been years since i road a 450/400ex but if i remember correctly, the 4 strokes were far more snappy, fun, easy and had usable power. So id recommend a 4 stroke for slow trail riding. My 100hp+ engine is an absolute waste for fast riding in tight stuff. 1 Quote Link to comment Share on other sites More sharing options...
SandSlingerOR Posted November 16, 2017 Report Share Posted November 16, 2017 I have dune ported stock cylinders, and I'm guessing 20cc domes, vf4's, stock carbs, pc pipes, lightend fly wheel, +4 timing plate 14-41 gearing 20" tires and Hella rich on the jets. It is a blast to ride, got pretty decent low end, but it's still a banshee. I am going to have Cam do a promod for me one day and a 4mill crank.

gusto Posted November 16, 2017 Report Share Posted November 16, 2017 Couple of things you can try. lean out your jetting move you needle for low end performance I had PC pipes and they’re all mid range. SLP is by far the best low end pipe so that may be an option. 2 Quote Link to comment Share on other sites More sharing options...
specialblend07 Posted November 16, 2017 Report Share Posted November 16, 2017 A banshee will never have good low end power without hurting top end power, you get one or the other and usually the low end never ends up being great. 1 Quote Link to comment Share on other sites More sharing options...

I agree with this statement to a certain extent... Depending on your setup you can definitely get good bottom end power out of a banshee (my experience) but he is right the top-end will not be like they r known for.

The fact that it's dune ported means you're already sacrificing a little low end. And that lightened flywheel is killing you in the trails. They really are more for drag racing where it gets revved up for the run and that's it. When you are in trails you need the extra mass on the flywheel to keep the inertia when you are in and out of the throttle. 1 Quote Link to comment Share on other sites More sharing options...

I've heard of heavy fly wheels helping in that department, but honestly I can't tell a difference. For being a stock stroke this thing rips and is a absolute blast to ride.

RagunCajun Posted November 17, 2017 Report Share Posted November 17, 2017 When I think of low end, I think of power before the power band. SLP pipes just shift the power band much earlier. I wouldn't mind a heavier Flywheel on my bike. Then again it doesn't need one. You mostly see that on two stroke dirtbike to get traction and/or tame the hit.
