I feel kinda bad about rubbing it in...........NOT! I'm sure one of these days the shee's will have to take a back seat to the thumpers. Gotta remember we're riding '80's technology. Naw, I take that back! The Shee's will never take a back seat to the thumpers! It's gonna have to be something NUKE powered to whoop a well built Shee!

It's a Boondocker system. He is running 100 octane. It runs really good, just not as good as a modded shee.... He has a pretty good hit when he's on the bottle.... He is changing from a 15 horse nozzle to a 20 horse...

A group of us went riding at the St Anthony dunes last Saturday. A friend of mine who rides a YfZ 450 has been trying everything he can think of to beat my friends '98 Shee and my '04 Shee. Pro-flow intake, Dr. D pipe, changed the timing I believe, gearing and who knows what else. When he would race my piped Shee, it would be a pretty close race....well, then he decided to go with nitrous and I decided to go with the Trinity Pro TT porting and a single carb. The guy he bought the nitrous from, "guaranteed" him "...it will beat any banshee..." Wrong! We raced up a sandy hill, approximately 1/8th mile, good enough for me to get it wound up in fourth gear. I whooped him off the line and was a good 2 to 3 lengths ahead of him at the top of the hill! I have to admit that watching him climb Choke Cherry, that the nos gave him a pretty good bump up in speed compared to running without it. When he hits the button, it makes a little pop out the exhaust, and it screams (not like a Shee though). Pretty cool setup!

ditto

If your looking for a starting point try 165 mains and 58 pilots? This is suggested jetting for dual 35's from the Trinity site....might be close for your PJ 34??? In my single PWK 39mm, I run a 165 main and 42 pilot at 3000 feet...Good luck.

If your at sea level try a 280 or drop 1 jet size for every 2500 feet in elevation you gain...just a suggestion though (Toomey recommended jetting, worked for me).

It sounds like your tors is kicking in and limiting the rpm. Either check to make sure all of the wires are plugged in or unplug them all. You have wires coming out of both of the tors on top of the carbs, a set of wires coming from your parking brake, a set of wires coming from your thumb throttle assembly and mounted to the frame under the gas tank in front of the petcock there is a little black box. If your throttle sticks with everything unplugged, your engine will rev sky high! You assume all responsibility for making sure the throttle is operating and maintained properly..... Oil mix sounds ok, although I would probably run at least 40:1. What's your elevation? 320 sounds a little rich to me........Check your plugs.

I have an '04 shee with T-6's, Trinity TT porting, blah, blah, blah....you can see the list below. The fact of the matter is, if you get the jetting correct it will run like a stripped @$$ed ape! I really doubt you would notice much of a difference between t-5's and t-6's, unless you dyno both sets. The t-5's may hit harder, but I couldn't imagine that...I can't get hooked up now! My buddy has a '98 shee with T-6's, Trinity MX porting, and everything else the same as mine, and it rips! With his MX porting his hit is a little milder than mine and comes in at a lower rpm. If you are just interested in the most power you can get, maybe, maybe the T-5's might give you a couple more horsepower. Thing is, a better rider with less horsepower can still be faster. Just my two cents......

Sorry, but the plugs do not fire at the same time...If that was to occur, the engine would be trying to fire the air/fuel mixture near bdc (bottom dead center) and the other cylinder near tdc (top dead center). Not gonna work that way. The only coil wire on a banshee is the two plug wires from the coil. You may have fouled the plugs. This can happen pretty easily with two-strokes. Put a fresh set of plugs in and try it again. Opps! I should have finished reading the thread....you got it going!

It all depends on the elevation you will be riding at. I run 19cc domes and 50/50 race/pump gas at 2500 feet with 5 degrees timing advance, and premium pump gas at the St. Anthony dunes (5000 feet). You may not need a 50/50 mix with stock timing and 19cc domes around the SLC area or higher.... You will notice a power gain with 19 or 20 cc domes...especially in the mid-range. My stock compression was 105 pounds and with the 19 cc domes it jumped up to 155 pounds....just to give you an idea.

Thank you all for the info. I will do a little searching on the site and make some calls.

Trinity wants $450 for either the Pro MX/TT porting or the Stage IV. Passion 12 port is $500.

I'm about to send my cylinders off to Trinity for the pro mx/tt porting, but I'm having second thoughts and considering going with Passion racings 12 port. Does anybody have any comments, good or bad, about either of these companies? Any suggestions would be greatly appreciated before I dish out the money. Thanks. Jim

Just outside of Boise

My family, friends and I will be heading over a couple of times this year. We will probably go over as soon as we get some warmer weather and the winter snow disappears for the most part. Maybe April? Depends on how much snow eastern Idaho gets. I tried to plan a March trip a few years ago and Egin Lake access was still snowed in.

My friend and I was there this last weekend. My buddy has a Banshee with basically the same mods as you listed except Trinity head, Trinity mx cylinder, CV 35mm single carb, Toomey tr-6 pipes, 14/41 gears and 20 x 10 x 10 sand devils 8-paddles. With me (experienced rider-175 lbs) on his quad and cooler temps in the morning, and very dry sand, it would pull the hill in fourth gear. My Banshee all stock except for the toomey tr-6 pipes and jetting mods would pull the hill in third under the same conditions. When the quads got heated up pretty good, I ended up having to drop a gear (both bikes) to get up the last little bit. My 04 completely stock with ITP sandstars 8-paddle would go over Choke in second gear... not setting any speed records though One thing that impressed the heck out of me this last weekend was when I pulled up to the base of Devils Dune (on buddies quad), completely stopped, then starting out in first and shifting up to 2nd then 3rd and going over the top with ease! Gotta do some more work on my Shee!!

A small group of us are coming over from Nampa Saturday morning. We will probably grab a bite at Sonic around noon or so, then head out to the dunes. Probably ride again Sunday am before heading back.

Heading to the St Anthony dunes this weekend with my family and a few friends. Gotta take my freshly piped 04 shee out to dust a few thumpers. Four strokes just can't handle the big steep dunes at St A too well. I like the Oregon dunes, thats a good place for a family vacation....mild temps and just a kick to ride the beaches and the trails. But for some serious hill climbs I don't think there is much out there thats better or at least closer for me. St A is a pretty big area several miles long and close to 2 miles wide in a few areas. My buddy and I have to put a couple guys and their YFZ 450's in there place...They have never rode a shee and they think their piped 450's are the fast things around!
