i am looking for input on the pipes i have on my sled. it is an 03 viper with speedworks tripple pipes and can on it. my question is should i keep the tripple set up or should i go back to the stock single. the speed works sound good, not to loud i think. but i have been told i am going to be sacrificing sound and power for reliability of the motor. i think it also has clutch work done so would i need to change that to if i did go stock? any advice would be appreciated,thanks
 
i know of a few piped vipers that have been reliable. they can b made reliable as long as all the precautions are taken to battle the heat issues, not just throwing on pipes and riding like alot of people think. things such as a rear heat exchanger, opticool head gasket, and possible getting the head mod to equalize compression between all 3 cylinders. these things along with proper jetting should keep u ok. a big deciding factor is that most get really bad gas mileage with piped vipers. there are many posts on here if u do a search with desputes about piped vipers.
 
i am installing a srx rear heat exchanger and the bender opti cool headgasket. but what is the head mod you are talking about?also i bought the sled used and the pipes came on it so i am not sure what the jetting should even be for the tripples.
 
Vipers have one cylinder that has lower compression than the others. Yamaha did this so u can run the same size jets in all 3 carbs instead of staggered mains like most other sleds. It is reccomended ( but I don't think its absoloutly necessary) to have this changed to equal compression when using triple pipes.
Others on here with them pipes will probably chime in to give u a good starting point for jetting, they will want to know ur riding conditions. When u do it u will still want to read ur plugs and make sure they are burning right to make sure.
 
Tripple pipes can and are reliable. Yours are nice pipes. I ran CPR's. With that said i went back to stock for MPG and i am now a family rider. If it was just me i would have kept the Pipes for sure. Loved the power and the response that you cant get from a stock viper. But i hear Heel clickers will get ya pretty close with stock pipes. Its just up to you and what your looking for.
 
livewire are you saying i should maybe swop out my viper head for something like an srx head? would the srx bolt up to the viper cylinders?
the type of rideing i would be doing is mostly trail and anywhere from sea leval to 2000 feet i think
 
Ran a set of speedwerx triples on an 05 Viper Mountain until one pipe came apart, I think this was due to the fact of not having a torque limiter. The pipes really wake the Viper up, definitely more power. And I loved the sound of them all the way until 9000rpm.
 
srx heads bolt right up but you need to have them cut the thickness of the viper headgasket and you either need a megapower water rail (hard to com by) or need to fab your own from srx water rail.
 
for this season i think i will stay with the stock viper head and hope that with the added opticool and rear heat exchanger it will be reliable for me. after i do that all i will need is some snow. almost january and it has still been in the 50's
 
Stags is correct. Most will buy aftermarket head (but a bit pricey) or just get the stock head machined, I see benders site is like $180 to get it done, other places I assume are about the same but not sure. Torque limiter will help keep the engine from torquing and by doing so helps keep your clutch alignment consistent while throttling it up. From what I hear helps alot when u have the added power of the pipes.
 
I have a modified Viper head from Jeff Simons of Simons CPR for sale. All three cylinders sized the same. it makes any piped Viper more reliable. PM me if interested.

I ran with the stock head, stock gasket, and just the stock rear mtn heat exchanger. Never saw a coolant light once.
 
I have the stock head and gasket...and Mnt Viper came with rear heat exchanger. No issues...

Pipes help out a lot, but also cut fuel mileage in half damn near. If you're going to do a ton of trail riding, you may not like the fuel cost. Mine gets a very consistent 6.02 miles to the gallon, and don't forget they also have to have 91 octane or better. A day for me is 40-45 miles average for our style of powder and hill-climbing riding, so I'd rather keep the higher track speed the pipes give when climbing...
 
one thing i dont like about the speed works pipes is the fitment doesnt seem to be so great. one pipe sits so low in the belly pan that it has melted it in one spot. and all of the pipes just about sit on top of the power valve cables. i was thinking i could use some exhaust wrap on the critical contact areas. has anyone had this problem or know if this fix will work with out hurting the pipes by not letting them cool properly?
 
heat shielding tape or something of that sort should help you, i have seen other posts where people had a relocation bracket for the powervalve servo so it gave u a little more cable to work with to tie them out of the way or whatever u have to do.
i am running into same with my bender pipes, not with the bellypan but even with hoodshims it is pretty tight to my hood and wireing goin to my guagepod, and some foam on the bellypan on the clutch side.

The fitment on Speedwerx pipes have never been that great. Speedwerx told me that when they made the pipes for a Viper they outsourced them to other companies so they all fit a little bit differently. I have a spot on my hood that melted down a little bit from them, yes this was even with the hood shim.
 
i am still looking to see what the correct jetting should be for these pipes does anyone know what might get me close. i am assuming that it has been jetted but i want to check it out to make sure.
 
I ran 162.5 mains, 47.5 pilots, needle at 4.0, and fuel screw at 2 7/8. I think this might have been a little rich but I'm at about 1000ft and like to ride in any temp even if it is -20F lol, so I wanted to be covered everywhere.

I ran a W/W/W primary spring with a 17.2 mm stl (4.5g) rivet in both holes with 8DN-10 weights.
