turbowrenchhead Posted January 18, 2013 Report Share Posted January 18, 2013 I have a set of good stock carbs. Any input on where I should start with the pilots and mains? I just did a compression test and I have 130 psi on both cylinders. Take a look at my sig to see my combination. Altitude here is 900 feet Quote Link to comment Share on other sites More sharing options...
turbowrenchhead Posted January 18, 2013 Author Report Share Posted January 18, 2013 I was thinking around 27.5 -30 pilots and 340-360 on mains Quote Link to comment Share on other sites More sharing options...

turbowrenchhead Posted January 20, 2013 Author Report Share Posted January 20, 2013 I still have to get the rebuild and tors kits for them before I can try them out. Quote Link to comment Share on other sites More sharing options...
bluebanshee98 Posted January 21, 2013 Report Share Posted January 21, 2013 since its ported i would throw a 350 in since its cold ( at least here) plug chop then go from there. a proper plug chop reading will tell you to go up or down on the jets Quote Link to comment Share on other sites More sharing options...
turbowrenchhead Posted January 21, 2013 Author Report Share Posted January 21, 2013 How does one do a plug chop with no chain or sprocket? Even after I get it mobile I still have no where to ride it. Quote Link to comment Share on other sites More sharing options...

sleeper06 Posted January 21, 2013 Report Share Posted January 21, 2013 Why build it if you can't ride it,plug chop is a must or Dyno ,the chain and sprocket thing your on your own,340 s shouldbe fine with a mild ported motor a starting point for sure,I have found FMCS like big pilots and stock needles all the way rich Quote Link to comment Share on other sites More sharing options...
turbowrenchhead Posted January 22, 2013 Author Report Share Posted January 22, 2013 I have no where to ride it around the Milwaukee area. There is a small section of road thats on public land that doesn't see any traffic. Its a pain but I have brought my blaster there to do a wot plug chop. I have to go at least 3 hours to get to the public trails. I was able to tune my blaster the same way. I don't see why I can't do the same with the banshee. Right now I have a 2-1 intake and a 35mm pwk carb. I have the stock carbs and the 2-1. I want to see what one will perform better for my combination.

turbowrenchhead Posted January 22, 2013 Author Report Share Posted January 22, 2013 Does anyone know of a cheap way of doing a wot throttle run while stationary? Quote Link to comment Share on other sites More sharing options...
SAVAGE420 Posted January 22, 2013 Report Share Posted January 22, 2013 Does anyone know of a cheap way of doing a wot throttle run while stationary? Motor needs to be under load. Run through the gears in the open air or on a dyno as said. Quote Link to comment Share on other sites More sharing options...
Paulie B Posted January 22, 2013 Report Share Posted January 22, 2013 My agressive trail port 370 motor with stock carbs had 27.5 pilots- 320 mains. The 320's were a tad rich but kept my motor happy. Quote Link to comment Share on other sites More sharing options...
lms1977 Posted January 22, 2013 Report Share Posted January 22, 2013 you could hold the rear break real hard, and load it that way up in the air while running it through the gears. Make sure you have a fan going to blow air at your head so its like really riding the thing...... but make sure you video tape it so we can all watch sorry I had to good luck with the tuning but yea you need to ride it Quote Link to comment Share on other sites More sharing options...
