ICULOKN Posted November 24, 2008 Report Share Posted November 24, 2008 Hello, I have a few setups I want to get opinions on: First Banshee 421 Trinity Cheetah 4mm Stroker Hemi Head Pro Circuit Pipes PLV Ignition Stock Box with K&N Stock Carb's I think - Need to check I just got this bike this week, runs great on the mid range but the low end and top end dont seem right. I think the low end will be fixed with some K&N's but what size carbs single or dual do you think should be on this bike? Second Shaved head 65mm Bore 4mm Crank Toomy T5's Stock Ignition K&N's On the above bike I have never had a problem with stock carbs and 300 jets. Think a 2 in 1 or bigger carb would help? Both of these bikes would be for Sand Drags, never had a 2 in 1 setup. Can anyone give me the pros and cons of them? Thanks for any help!

It has a crappy low end because the cylinder is drag ported right out of the box. It has a crappy top end because the pipes are choaking it on the top end. Drag Ported Cylinder = Drag Pipe (inframe or out frame) I would recomend a pair Keihin PWK 35's. Quote Link to comment Share on other sites More sharing options...

Think a 2 in 1 or bigger carb would help? Is this machine ported? If not, then that is where you need to spend some money. I would stick with dual stock carbs before I went with a 2:1. A 2:1 suposedly helps out in the mid range but it kills the top end. Quote Link to comment Share on other sites More sharing options...

That bike seems to run well for what it is. Thanks for the tips! Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted November 24, 2008 Report Share Posted November 24, 2008 What are some good Drag, in frame pipes? Toomey's? You pretty much have 2 choices for inframe drag pipes. CPI's and Shearer's CPI's come on a little sooner and Shearer's have a little more top end. I went with CPI's on my banshee because I wanted the power to come on a little sooner. Both pipes come with ok chrome. It isnt the best, and has been known to peel. If you want show chrome then you need to get them from www.cascadeinnovations.net That is where I got my CPI's from. If your wanting the CPI's with standard chrome or bare steel then PM Frogger on here, see what he can do for you. Here is a pic of my CPI's. It will be a huge change if you go from Pro Circuits to CPI's or Shearer's. I ran T5's on the motor in my sig before I got CPI's. It was a huge change going from the T5's to CPI's As for the other bike running T5's what kind of port job does it have? Quote Link to comment Share on other sites More sharing options...
