Seems that everyone that has a Rincon has no problem riding wheelies and beating Grizzlys except me.Ive done the jet kit and added a K&N filter but thats it so far.But I just havent seen the performance gains that everyone else has.I know I have the jetting right but it just doesnt have the bottom end grunt that Im looking for.If all else fails I will try the MBRP pipe to see if that helps.If anyone has any other suggestions it would be very appreciated.

Saw this on another site about carb settings:

carb basics :

idle to off idle= pilot (or mixture screw)
off idle to 2/3= needle
2/3 to WOT= main jet

Now, wether you are lean or rich you can tell a few differnt ways, the easiest being checking your plug and the color of it. Black = too Rich, White = Too Lean.

The very first thing to try since you put the Dyno Jet Kit in and you say you are lacking low end. Re-adjust the Air Mixture Screw on the bottom of the carb (you can get to it by taking right panel off, you don't have to pull carb out). Screw it all the way in, then back it out 3 turns. Crank your bike and let it warm up, then try it out. If still nothing, your jetting could be wrong or you could try backing the Mixture Screw out another 1/2 turn (that's what I ended up with).
Try these things tonight and get back to us with results.

When I installed the Dyno jet kit I went buy the instructions (144 main,clip in second groove,2 and a half turns out on the mixture screw)and it had a bad bog on take off so I pulled the needle and moved the clip to the third groove and a half turn out more on the mixture screw and it went away.So buy dropping the clip one groove I am increasing the fuel I think maybe someone on here can confirm that?

Your pilot is separate from your slide, main jet, and needle. When you push in your throttle you lift up your slide and attached needle out of your main jet. The more you move the clip up on your needle the less gas you get out of your main unless you are full throttle. So if you had your clip in the top of your needle it sits for longer in the main jet which might cause a mid range drop. If so move it down one more notch and try again. You must remember when working in the carb that if the machine is at idle and you push the throttle all the way in all at once you are not testing your needle, or pilot, just your main jet. So to finish up this is what I do.

1 Blip your throttle - if it bogs then adjust you air fuel screw
2 hold throttle half way down - if it bogs move you clip down one more notch on your needle
3 push throttle full - does it accelerate smooth? If not go down 1 size on your main and try again.

Also you can not see if your machine is running lean or rich by taking out your plug and looking at the porcelain. The reason why I say this is that if your machine has been at idle for a few min then you are getting readings from your pilot. To see how you machine is running under full throttle you need to bring second gear up to redline and then hit your kill switch and come to a stop pull the plug and now look at your plug. The reason I say 2nd gear is so that your plug has a chance to clean itself.

Good Luck,
Kevin

Before moving the clip I tried adjusting the mixture screw and it didnt help thats why I moved the clip down one then re-adjusted the mixture screw.

Well I just got done doing the exhaust mod and did notice a little increase in power but I just read on another thread where some just put dirt devil 27"s on there Rincon and can still pull the wheels.I have tried everything except buy a pipe to get more power.Change the jetting every way with no results,added the Dyno jet kit,k&n filter and now the exhaust mod with very little gain in power.I only have 250 miles on it could it be that it just isnt broke in yet or is there something wrong with it?

Also, have you had your valves adjusted yet? Made a difference in mine after the break in period. I have 27" 589's and can wheely without even pulling up, and most of the time I can wheely even leaning over my handle bars.

After reading this thread I think my stock settings are wrong. If I understand a "blip" of the gas should not bog the engine. When i quickly go wide open it bogs and sputters. I read on someones repy in this post that its the air/fuel screw? If this is correct it would explain why i cant get the stock tires to raise when i give it gas...please give some advise.

1st when I wheelie I need to be at a stand still with firm ground under my tires and then I just hit the throttle all of the way down. Mine at 1st would bog like yours but after I turned up my idle about 100rpm and took the slack out of my throttle cable all is great.

I tried to take the slack out of throttle cable and was unable to do this...does anyone have a picture of this? Also, how did you turn the idle up by 100rpm? I am so sorry for sounding ignorant, I just havent dont this before. The only thing i have done is on a old kawasiki bayoo 250 i rebuilt the carburator with my brother once...

I took it in around 175 miles and had everything checked they said the valves were fine.But i still have a hard time believing that there is not something wrong with it when someone with 27" 589's can pull the front wheels like he says and mine can barely pull the wheels with me pulling back as hard as i can or standing on the rear rack.

Tim, I was just wondering how many miles yours has on it?

Mine has around 700 miles on it. Yes, it is very true, my 27" 589's will come up not pulling back at all, just hitting the throttle from a dead stop.
Couple of things come to mind. Screw the pilot screw all the way in, then back it out 2 1/2 turns, adjust your idle if it needs it.
My Rinny really gained a lot of power after about 250 miles and it feels as if it is still getting stronger honestly. Maybe you just need to give it some time to break in? When I first got mine and until about 300 miles, I had to pull back on the handle bars pretty good to get the front end up. Now that might just have been b/c it was not tweaked right or whatever, not sure.
Also, my valves were definatley outta whack when I took them in. I felt a big difference in power when I got my bike out of my 100 hour check up. So, maybe the dealer is lazy and didn't check them?

Try those few things, maybe it's just milage?

if you have the stock exhaust, you need to have the 144 dj main jet in and the needle on the second notch. If you make it slightly too rich you will actually loose power. Try your mixture screw at 2 and 3/4 turns out, and make sure all of the stock spacers are in their original place and the dj spacer is on top...

...you should have seen a big gain with the dj kit.

To adjust your idle you need to take off the cover on the same saide as your throttle that says Rincon on it and you should see a black knob that you you turn. To adjust make sure the engine is warm and then turn the knob clockwise half a turn or so. If you don't have a tach then you will just need to just listen or you could bring it to your Stealer. Your throttle is adjusted by pulling back the rubber boot next to your throttle and then you can loosen the holding screw and back out the bolt till you don't have any slop in your throttle.

Hope this helps,
Kevin
