I got a newsletter from High Lifter, and looked around for performance mods for the TRX680. A HMF Exhaust, Programmer, K&N, Outerwear's. There end price was well over $500. I then looked at Rocky Mtn ATV, and they don't have some or most components. Matt though at ATV Outfitters has the complete kit for way less the HL, but shipping wasn't included.

I'm looking to breath better at 12K feet, but not to wake up the dead either.

Can anyone recommend anything. A different ATV make is not the answer. So keep your off topic comments to yourself.

You should be able to find a pipe that will not be much louder then stock.

A good pipe, and air filter should provide enough power to make a difference.

Are you looking at cams or big bore kits?
Or
Are you looking to keep it simple?

A open pipe is typically good for an 8-10% gain. The filters on Can-am efi's have proven worth 0 gains. I have not had the Rincon on the dyno so I am not sure what its making at the wheels, but the factory crank rating I believe is only something like mid 20s. Who knows though maybe the Honda is takes to mods better than the EFI can-am. I have noticed that it looks like a pipe would be sort of tricky since the OEM is mounted sideways right off the back of the machine, and the rear suspension seems like it would be in the way to convert it to straight rear exit.

Anyway the HMFs are normally pretty loud pipes on big singles. They are not to bad on twins.

I have the HMF ECO Series on my 04, it meets all of noise requirements for the forest service regulations plus an approved spark arrestor.
When I installed my pipe I did not tell anyone in my group, just to see if anyone would complain if it was too loud, I had to tell them I had changed the pipe from stock.

I run a UNI filter, I also have the K&N with outerware but after cleaning and re-oiling the K&N I held it up to look inside and I could see pin holes of sun light shining through it, it sits on the shelf in the garage now. I ride in very dusty conditions and I am not going to chance dirt getting through the holes.

If I were to do the exhaust over I would go with the Super Trapp ISDX , it exits in the same location as the stock exhaust.

The FMF is the only aftermarket exhaust that does not reqire re-packing, (they don't use it in theirs) when the packing in the exhaust wears out, but it is a little louder.

You will need a FI controller to adjust your fuel maps with the addition of a pipe and filter.

If you guys want straight answers from Rincon owners visit this site. Rincon Riders

I seen or read where the 1 muffler meets USFS regulations. The kit includes the programmer, K&N, Outerwear's, and muffler w/ spark arrester.

No engine work as a cam.

I post'D the question on Rincon Riders.

Thanks...

Boy I feel like a fish out of water in here!

Check your PM's. Are you coming to the pot luck?

You are a fish out of water, but since we know just how big of a HONDA lover that you truly are we will welcome you anytime.

I ended up talking to the service guy at the Dealer I bought it from. Kind of or tried to talk me out of a K&N. But he did sell me air box vent filters. He uses them on his Polaris, and said they helped it here in the coal dust. Drill a 1 inch hole in the lid and insert the uni filter(s). I have the lid modified with 12 of these uni filters. I had since ordered a K&N along with an Outerwear's from Dennis Kirk.

At the moment I'm fighting a cold, so a test run of just the airbox lid modification is out of the question.

Hah, you should read my posts on the same matter here and on Rinconriders.com For the last two years my 06 Rinny struggled to get me across the mountains. This last year I did the Dynojet Power Commander UNI filter and 2" tip dyno tuned with a wideband air fuel gauge. It was a negligible gain I hated the noise and I bought a Brute Force 750 two weeks ago. You just aren't going to make more power out of an EFI Rincon. The TRD gear is a risk you can take but that is over 500 bucks and may or may not work quietly or well...
I have my Dynojet PC3, UNI filter, and 2" tip for sale if you wanna try it...

I rode with the lid off so I could put it back on in case of a water crossing.

TX~ I have my 06 since August of 06, your 2 links were written this year.

I had mine since Dec 05. I couldn't find the exact ones I wanted to link off RinconRiders.com I have been crying about my loss of altitude power for 2+ years over there. I wasted 5-600 bucks trying to make mine "more powerful". I just wanted to save you the hassle. The only real improvement would probably be the TRD gear but I wasn't going to risk another 600 bucks. An engineer friend took one look at the gear and said it was a bad idea. Getting more power out of a FI Rincon is like getting blood from a turnip. Good luck with whatever you choose.

Another fish here, I agree with TX, not just the Rincon, but it's true for all quads, it's difficult and VERY expensive to get more power. You can easily lose HP with the wrong pipe.

But I think you are on the right track by trying to get it breathing better with more air. I've seen quads struggle and go from not making it to making it just by removing the airbox lid. Sounds like CO Mtn Man would be a good resource. He rides the same hills I do. Just don't try anything steep at high altitude, you won't make it. Best of luck.

I'm not a mechanic by any stretch of the imagineation, but my take is these quads aren't real big on HP. If you are running say 40 horses and try for a 10% increase which would be huge that is only 4 more horses.

The delima of the Rinny is the lack of a lower gear than 1st and low HP to begin with. There is a lot more loss in the Rinny auto transmission than in a belt driven unit. At 10-14 thousand feet you loose 8-10hp due to air density. So when you start out with only 36hp you are really struggling with 28hp and no low range. A pilot buddy of mine was saying the atmosphere at 15K is about half what it is at sea level. I know our drag cars lose up to a full second just going up to 4-5 thousand feet. My turbo diesel tow pig looses a lot of nuts through the passes up there. Down here I run 34-36lbs of boost yet over Monarch, Raton, Cottonwood I am lucky to make 22lbs of boost.
My buddy with the 800 Bomb can ride wheelies in high and will flip over backwards down here at 600ft elev. Well we unloaded it in Taylor Park at 9800ft and it would not even pick the wheels up in high.
It looks like Cob and I have climbed the same rocks. I am a picture taking fool... It is a good thing though as sometimes people don't believe what they can't see.

Was there a trail that ran to the top of Antero? We got to the lower summit and it looked like the trail was cut out or washed out that went around the corner and up higher. I was scared to go higher anyway since the Rinny was sucking wind so hard a toddler could have held it back, lol.

I'm a mechanic in my imagination too...

I think it's "you lose 4% hp for every 1000 ft you go up. I know here in the Springs, we are down 25% in hp.

Antero is one of the best tests of proper jetting for carbed machines I know of. You can't drive to the peak, You have to walk across the ridge to the north east, looking at the GPS (nice shot) you were at the end of the trail for Antero peak. Basically a rock pile with a trail running around it.

Did you go over the saddle and down to the lake on the other side? One of the best places to stop for lunch I know of. Beautiful. Also a lot of garnets up there. Usually always spot some rock hounds picking away.

Well I guess I'll need decide once I get out there if I want to attempt Antero. Will have to do Flag and Napoleon, then decide if it got any better.

Thanks all that replied, input appriciated.

That Razor is looking better every day.

We finally found Napoleon last year, it was so much fun I did it twice..

American Flag Mtn. is a fun one, pin the gas at the bottom and never let off, untill it levels off.

You'll do fine on Antero Kenny,,,don't miss it. And check out the side trails on the way up.

Agreed. It's not too steep.
Well worth the views!!!
