wmbw Posted July 3, 2018 Report Share Posted July 3, 2018 I actually have a few questions on this topic, any tips, pointers, or opinions are appreciated. '01 banshee, stock motor and carbs. Only mods are toomey t6 pipes/silencers, tors delete. Running 290 main jet, 25 pilot at 2,000ft. Air screws are 2.5 out. All the way through the throttle, 'shee rips. Plug chops indicate things are running great. However, I still have the tiniest bog when I first touch the throttle. Way below 1/4 throttle, more like only at 1/16th throttle. Am I being picky? Can that bog be cleaned up? I'm running 91 pump gas 32:1 but plan to switch to 100 fuel. Lastly, my next ride will be some pine forest trail riding at 6,000-7,000 feet. Any suggestions on what jetting and carb adjustments I should make? Thank you bansheehq people in advance for your wisdom!

wmbw Posted July 3, 2018 Author Report Share Posted July 3, 2018 I also would like to gather some exhaust opinions. Happy with my toomey t6's but I'm in the process of making her street legal (so that I may ride all forest roads.... and maybe a drive thru, once) I need a spark arrestor and am concerned about noise. Toomey has add-on arrestors but also a hush kit. I hate the idea of the hush kit but will buy if I have to. Any idea how loud the t6's are? 96db is my limit in Arizona.Sent from my SM-N910V using Tapatalk Quote Link to comment Share on other sites More sharing options...
Ayesully810 Posted July 3, 2018 Report Share Posted July 3, 2018 You could run the pro circuits with the forest approved spark arrestors, i think you will like those better than t6s too as far as that small bog, try turning your air screw in. you shouldnt need a bigger pilot with those mods. Look through the jetting page thats sticky and almost all piped stock bikes are fine with a stock pilot, if your riding in cold conditions you could prolly go up a size but 25 is fine where your at now, try turning the air screw in a 1/4 turn or so 1 Quote Link to comment Share on other sites More sharing options...
wmbw Posted July 3, 2018 Author Report Share Posted July 3, 2018 Hey! Thanks. What about jetting for altitude? The temps will be 85-65.Sent from my SM-N910V using Tapatalk Quote Link to comment Share on other sites More sharing options...

Sent from my SM-N910V using Tapatalk better bottom end to mid range. They are a snappy pipe imo i loved them when i had them, you could gear it differently for the road for some more top end too. if i remember correctly, i think a jet size for every 2k elevation change, close to something like that. So for higher elevation you jet leaner because there is less air, so your mixture is getting more fuel to air ratio. So if your a 290 you could run a 270 or 260.

trickedcarbine Posted July 5, 2018 Report Share Posted July 5, 2018 Pro Circuit does have a USF approved silencer. There is also the Toomey stuff, but I've just never been a fan of the Toomey performance. You could also do SLP's and I believe JDS is making sparky tips for them. 1 Quote Link to comment Share on other sites More sharing options...
sleeper06 Posted July 5, 2018 Report Share Posted July 5, 2018 One jet size for every 3000’ above sea level. When you get there drop to a 280 and play with needle and air screws till it’s good. Obviously bring a cpl jet sizes to cover your ass 1 Quote Link to comment Share on other sites More sharing options...
ZillaFreak Posted July 5, 2018 Report Share Posted July 5, 2018 Don't switch to 100 octane, will just be pissing money away for nothing. Have you tried a 27.5? 1 Quote Link to comment Share on other sites More sharing options...
wmbw Posted July 5, 2018 Author Report Share Posted July 5, 2018 I haven't tried changing the pilot jet. I've only recently purchased it and got it running "correctly". I will definitely give it a try as I do more work on it before this riding season. As for the pipes, I'll probably keep them for this season as well. Next summer, I plan to do an overhaul of the suspension and I can get new pipes then. Happy to gather opinions on reasonably priced suspensions and the value of going +2/+4 etc... I ride everything from dunes to forest trails so a balanced setup is ideal.Sent from my SM-N910V using Tapatalk Quote Link to comment Share on other sites More sharing options...
