Patriot porting plus Trinity single 35

[oldturtle]

I bought 2000 Banshee in March and only had one ride and that was cut short due rain at Oregon dunes. Got home, checked comp and only had 105 psi both sides. Sent barrels and head to Patriot for their bore with Wisco piston, hot trail porting and full head deck and dome for pump gas ( 21mm equiv). While waiting I deceided to go with the Trinity single 35 mm carb set-up. Trinity offers either an adaptor to use stock air box or a clamp on filter with no air box. Graydon-Proline only offers clamp on with no air box. So I get the Trinity air box adaptor plus a pro-flow clamp-on adaptor for inside the air box. My idea on keeping the air box was it will give more protection for filter plus I would have the option to use lid if necessary to richen mixture on cool evening dune rides.

My present set up is FMF Gnarly and Quiet Core 2, K&N with outerwears and no lid, 195 main, 55 pilot, clip 4th from top. I ran about 3 gallons thru her, breaking in motor per Patriot recm. Now I am just getting to point where I can start turning it on. I am very impressed with the hit. It will pull nicely at low throttle when cruising yet will really hit with authority when you want to, a huge improvement over my worn out stock motor.

Only had 2 problems. First problem is that the adaptor from air box to single 35 mm carb is really a poor fit. I had to shim up the rear of air box about 1/4 inch to get even close to having the carb line up with rubber boot in front and billet adaptor in rear. Rubber boot not all the way up on carb and rear of carb not all the way into O-ring adaptor. Phoned Trinity and they claimed that they have sold hundreds of these air box adaptors and have never had a complaint. Hard for me to accept with all the problems I had. But it is holding together. It just looks like it could come apart anytime. In hindsite I believe I should have gone with the straight clamp on with no air box. So I would sure like to hear from some of the hundreds of Trinity air box adaptor purchasers about how their air box/ adaptor/ carb all fit up.

Second problem was with a tree stump at Winchester Bay, Oregon on only second day of riding. I hope to get report on Dune topic list about broken tie-rod ends, totally ruined wheel, bent A-arms, and not sure what else.

I got the trinity cv mainifold 35mm setup with airbox adaptor.. I was kinda mad at how much I had to grind down on the carb, but its understandable because they make one adaptor to fit the 33 and 35mm carbs, so in order for it to fit both they just made it fit the small one. I just used a file around the outer lip till it fit. I didnt take any length off of it, which is what you make it sound like you did.

 

I too wish I got the K&N setup, but thats only because I hate my airbox more then anything. I have my airbox so modified that its basically not there. But it still causes a pain everytime I want to work around that area.

 

Other then that, I havent jetted mine in yet, only because I dont know how to jet, and my local stealership doesnt have any jets I need..

 

I dont see how you feel it will fall off though, mine fits snugly between the 2:1 adaptor and the airbox piece. Once I start to jet it in I will like it though, just losen the clamps, rotate 90 degrees and bam, easy access to the bottom!

Hockey, I filed only the outside of raised lip on carb until it would slip into O-ring of adaptor but I cannot slide it in all the way to the stop because then it would not clamp onto the rubber boot on intake manifold. I didn't shorten the carb any. I just think it's a poor design.

Trinity had 195 main, 52 pilot, and clip in middle slot when carb arrived and that was their recommendation. With the 52 pilot I had to run air screw out aver 3 turns so switched to 55 pilot with air screw out 2 1/2 turns. I also moved needle clip to 4th from top. Left main at 195. It runs great from bottom to top only I havn't been able to get a good run in 5th or higher gear to get a good main jet plug check. I might wind up bigger on the main. All the extra jets were included with the kit.

sounds to me like something on your bike just doesnt line up right maybe? mine fits perfectly between the 2, and i havent heard anyone else comment on a poor fit.

 

as far as jetting, i think I'm going to move my clip position because I have a poor low end. i just ran at the dunes for like 45 mins and looked today at my plugs and they look pretty good, so my mains are close.

 

I bought it to give me more low end, but I still think my power down low sucks, so thats a sign she isnt jetted in right. We will see...we will see...

 

Do you have a digi cam? Take a picture of how yours fits and post it up.

I had a hell of a time getting that damn adaptor on!!! what i did was dremmel out the front of the front mounting tabs so i could slide the air box in from the back. It seems to work all right but i've had to take it apart to install reeds and what a pain in the ass. Then since i had to file down around the carb it made it sharper so it cut that damn o-ring. It all boils down to poor engineering. I put some silicone around the adaptor just incase it wasnt sealed good enough.

 

BTW im running bills pipes, v-force reeds, k&n and no snorkel. Does 52 pilot, 188 main, and 2nd from top clip position sound right?? it seems to run strong mid to high end, but the power still aint there on the very low end.

I too cut the tabs off the airbox. Mine fits really good no problems. I haven't taken it off yet so that may pose a problem. The trinity sure makes riding more fun though great power and no sore thumb. Jetting takes longer to find my tools and spare jets than to actually jet it.
