BansheeGuy_IV Posted December 30, 2004 Report Share Posted December 30, 2004 Holy Cow! That sums it up. I've been doing banshee performance for 10 years. I've built many an engine, including some big bores. Jim's 12 port stroker is the first time I've been a little scared. I've been doing some jetting runs, getting her dialed in. I'm close on the jetting now. I've got a little more tuning to go. The power, when it comes on, is unreal. This is one mod that is for advanced riders ONLY. The low-mid range is acceptable. It's similar to my last 350 setup, even though it still needs to be dialed in. The mid-top however is ridiculous. It's SICK! It's Arm Wrenching. I LOVE IT.

fixitrod Posted December 30, 2004 Report Share Posted December 30, 2004 What til you through some 34mm or 35mm carbs on it. You'll gain from bottom to top. Quote Link to comment Share on other sites More sharing options...

jinx44 Posted December 30, 2004 Report Share Posted December 30, 2004 I would recommend staying away from the TM's. I have ran them because I also had a lot of jets and needles. I the tried the 34PJ's and loved them. With the keihins, you only need one needle and a couple jet sizes to get it right. The same jetting and needle works with 34PJ's or 35PWK's. Your clamp-ons won't clear with the rockets? The rockets I tried had a lot more room than the CPI's in that area. Put some more gear under that thing. It can take it. It will actually do better under a little more load. Try a 15 tooth, you'll like it. Quote Link to comment Share on other sites More sharing options...

BansheeGuy_IV Posted December 30, 2004 Author Report Share Posted December 30, 2004 Still Jetting! I am getting really close on the tuning. I am at 400 mains, 5L1 Needles on the richest clip, #30 pilots. I may actually lean the needles up one notch and give it a run. I think these needles are the ticket though, it really came alive with them. I still may need to drop the main jet to 390's or 380's. As it is now, it runs great. I'm just a stickler for fine tuning. My only beef right now, is getting a smooth idle. I set the idle where I want it... It sits for about 30 seconds and slowly rides up on me higher than I'd like. I turn it down... But then she'll stall subsequently stall. It's a little fickle. It's actually an issue I've had with the 28mm TM's since I've had them. So I've got to work on it. I may need to even go a little bigger on the pilots. I'll go to 32.5 next. But it's a work in progress. The power comes on early and strong. To be honest, I think it may be a little bit much for a trail bike. It doesn't understand the concept of slow any more. Hehe I'll get finished pics up when it's all done being jetted. I'll rewash it, and then post 'em. Probably a few days before I get it where I want it. BG Great to here that!

BansheeGuy_IV Posted December 30, 2004 Author Report Share Posted December 30, 2004 I'm running 14/39 gears right now for because it is mostly a trail bike. I'm trying to keep it tame. I am sure it would pull taller gearing, but I don't have any need for more top speed. I bet right now, it'll do mid 80's, but I haven't checked. My friends ride 4X4's. I don't think I have to worry about them getting me down a long straight. Hehe I rarely top 60mph on a ride. I'm mostly an acceleration junky. Get me from 0-60 in a heartbeat and I'm happy.

superchicken Posted December 30, 2004 Report Share Posted December 30, 2004 i trail ride my shee alot and the 17 is good.alot less shifting and just a tad bit of clutchin when doing some slower technicle stuff like tight turns,and off camber hills.maybe a 16 would fit you well Quote Link to comment Share on other sites More sharing options...
jinx44 Posted December 30, 2004 Report Share Posted December 30, 2004 I trail ride at 15/41 with a stock engine. My ported 350 trail bike also runs a 15/41. Its a good gearing and lets you stay in the midrange better. I run 16/39 on my passion stroker for TT racing. Quote Link to comment Share on other sites More sharing options...

die_infidel Posted January 15, 2005 Report Share Posted January 15, 2005 I run 16/40 gearing on my passion an it still pulls it like a mother $#$@!. Stock gearing i had no control spun the tires way too much. Nice job done JIM!! Quote Link to comment Share on other sites More sharing options...

05bansh Posted January 16, 2005 Report Share Posted January 16, 2005 If you are willing to drop the $$ maybe check out the Lectron Carbs by Packard Racing. Completely illiminate jetting. They run about $300.00 a piece. Quote Link to comment Share on other sites More sharing options...
rebelbanshee2 Posted January 17, 2005 Report Share Posted January 17, 2005 Id gear it up. It will help tame it down on the trails. Too low gearing and it just revs out too fast and seems peaky and burns up the tires. A taller gear softens the power and lets it pull longer, and hookup better too. You just heave to use the cluch more, with is good becasue you can control the power even more. Im running 15/38 its great for woods, I can keep it in 1st and just work the clutch on most trails. When you get the bigger carbs its going to have alot more low end too. I could believe the difference between 33PWKs and 28TMs Quote Link to comment Share on other sites More sharing options...
