Just got done with the mod plus a UNI filter, it was worth the time and money. I have a lot of heavy stuff on my Rincon and it will now bring the front end off the ground.

The bottom end and mid is great but I lost about 4 mph on the top; went from 61 to 57 mph? Started at the recommended settings of DJ144 main, clip on second groove, all washers as indicated and then tried the third groove. On both groove positions I tried both 3 and 2 3/4 turns out on the f/a screw. It made no difference on the top speed reached. Left it at second groove 2 3/4. And I did reset the ECU.

Any suggestions? I am at about 600 feet of elevation.

parkgt, can you please direct me to the steps for resetting the ECU?

 

[parkgt]

Jason,
Just type ECU in the search field one ot the posts gives the instructions.

Parkgt,
Does the 4 mph really mean that much? I have yet to go anywhere that I needed 61 mph. I appears that everyone guages their Rincon by doing some high speed.

Thanks Greg!

Ridge Runner,

I agree with you; I would much rather have the grunt down low and in the middle than the extra top speed. On the forest service gravel roads between trails I will cruise at 40 to 50 mph at times.

I don't need the top speed, I just don't want to be missing the best tune possible; if there is such a thing.

I agree with you Greg! I reset the ECU and still with the throttle wide open it only gets to 53MPH on the road!! So i know something is screwy because it is stock! Stupid thing just lost 10 MPH for no reason.....ARG! 03rincon I could use some of your expert advise or help with the bike

we'll check it when i get back from hunting. Its got to be something simple just needs another set of eyes to look at lt.

Greg,
I fully agree. I too installed the Dynojet and the increase in power and response was great. However, I never knew what my top end was stock, and I don't know what it is now.....and it is not important to me. I have had it up to 57 MPH but ran out of straight road. What does that mean for the Rincon? The only concern I have is will the Rincon pull me out of any situation I get into (it has). I have rock crawled, climbed hills, and treated it like I would a small Jeep. Wheelies, going 63 mph, etc. are not what the Rincon was designed for. They did the same thing with the Jeep CJ-5 (later the Wrangler) and that is why the insurance rates are extremely high on them. I am not as youg as many of the riders but I truly enjoy it. I want all the power I can muster, but speed is not necessary. Incidently, I have the 144 jet, the K&N filter w/pre-filter, and the mixture out 2-3/4. Runs great.

i am certainly no engine or carb expert, but i would think that a propperly jettet bike would make more power across the board, ie slow med and high speeds....could some one privide some insight??????

You may be able to go one size smaller on the main jet and move the needle clip down ome notch to add fuel to low and mid range...you may be slightly rich on top which would take some accereration away from the very top.

Check your plug at WOT and see what it loks like. If its black, then you may be able to reduce the main jet as I mentioned....

Guys, reseting the ECM does nothing as far as a performance gain goes.

 

[marine]

let me emphesis that I am not concerned about my speed directly. I am more concerned that I am not using the full potential of my bike. I will not be doing wheelies all over the place or jumping the thing or running 70MPH everywhere. My only concern is that other bikes are doing 60MPH stock (to me this means more power). The fact that mine is slower is a need for adjustment to get more power and acceleration. If I had wanted to go fast everywhere I would have gotten the 450ex ATV...

 

[Yellow650Rincon]

Jason, that's part of what the Rincon is. It's a quick/fast sporty utility. That's why we got it. It's a blast when you can go flying by your buddies at 60mph when they are on their slow utes, and still be able to do the same thing as them when you get to the trails. That's why I love the Rincon, it feels so sporty yet has such great utility/trail abilities.

With your top end problem, I am thinkning you might want to have it looked at. Some people around here have said there are "bad cams" out there in some Rincons. *shrugs*

 

[rhinohd]

Well my jet kit is going in tomorrow and I hope to get the same results. I don't want to lose too much top end because it does in fact matter to me. We do a lot of blasting through long straight flats and would hate to lose out to some of my buddies! I will let you know what kind of results I get...

 

[marine]

Yellow I said that I would not be running 70 EVERYWHERE. Of course I bought the rincon for its sportiness! There are occations (like lake beds, long open trails) that I want to open the thing up and haul some butt! I am simply saying that i dont drive fast all the time and if i had wanted to do that I would have gone with the 450EX. If I didn't want the power and the accelaration I wouldn't be concerned about this "problem" I am having.

I am going to let 03rincon take a look at my bike (he is close and a mechanic, unlike me). If he can't seem to figure out why this bike is acting up then I will take it in to a dealer and let them adjust the valves and check the cam (whatever a cam is LOL). Thank you for your help early 03rincon! If you drink I will have ya covered when you look at my bike...if ya dont drink..well, I will have tons of cokes and tea hehe!

My guess is that you are to lean on top end. I think I posted here about rejetting my rinny where I live (600') and running it at 3000'. At the dunes, (3000') it would only run 54 on a hardtop with stock jetting. Pulled the plug and it was very white. Almost to much so. I did not use the DJ kit and rejetted it to 160 at home the day I left to go back to the dunes. When I ran it there again, it was very rich. Flooded down on steep climbs. I pulled the lid off the air box and it was much leaner. Ran it again on the hardtop and it was up to 60. Pulled the plug and it was still a little white but beginning to turn tan in places. When I returned home, I replaced the lid and ran it again for a day of trail riding and checked the plug and it was a pretty tan. At idle, it runs a little rich but after running it hard, the plug looks good. It definitely has more get up and go. I guess I will give in and get the K&N and maybe the DJ kit. I am supposed to have a Supertrapp exhaust coming my way in the near future and will redo everything when I get it. But for now, it runs great with the 160.

Duramax, what is the 02 Duramx in your signature?

Ok folks,
I too am the proud owner a Dynojeted Rincon. Worth every penny! I ripped abound the block without the normal hesitation it used to have. It also idled better! I then pulled onto my wet asphalt driveway, stopped, and then nailed it. The front end came right up off the ground! Mind you I am a very big guys so I was WAY surprised! Thumbs up on the mod! Oh It took me about 2 hours (putzing around) to do that and change the oil...
