I had the Foreman 500 and my Rincon dyno tuned at mud mania on friday

I will post the actual dyno sheet if anyone is interested. One thing with the foreman 500 is that when they where testing it they Dew point hit and the pressure actually rose so I lost HP but the dyno people said it was only the weather causing it and that I actully picked up HP. These are the final setting. Okay for all you dyno jet fans I must tell you the DJ jets just plain suck. Truegrit sent me a 170 main jet and that is what I have been running. But hwat I have found out is that it was a Mikuni jet. I was a little rich down low on the main and when the bike was run I actually went a little lean on the needle. So they tried a DJ168 main and the bike made no additional HP other than having a fuel air mixture that was right the flow on the main jet was choppy and all over the place. Now the Mikuni jet was a clean nice arce. So they tried a kehien jet and it had the same result as the DJ. They also place 2 small washers under the factory needle to richen the bike a little at higher RPMs. So what they ended up doing was leaving in the 170 main and it was just a little rich. They bike was makeing great power and more torque than HP. But the weather didn't cooperate and I would have had to wait till the next day to have them run it again. But I didn't bother. Bike is makeing a bit over 15 HP and the dyno people have said that with them leaning it out on top some that I probably picked up about 1.5 HP. So I am saying right at 17 HP for the foreman 500. And no I cannot prove that number but I do know it revs alot harder now than when I started.

Okay as for the rincon I had it done also and they spent 2 hours with it costing me $150 for that bike but I got the highest HP reading they have gotten yet out of a rincon. My rincon made 25.5HP at the rear wheels. Also it made a flat 25 Lb FT of torque. Now I must tell you a modded out Brute Force was only putting down 28 Lb FT of torque so no one can say that the rincon isn't makeing power. Now lets get some gears in 'em so we can make that power work.
I will scan in the actual dyno sheets if anyone wants to see them.

I would like to see the sheets, if the DJ Jets suck so much, why did you end up using it?

I didn't use it. They put the mukuni 170 jet back in it. The dyno people were shocked at how bad the DJ jet flowed. It wasn't that the bike made less HP with the DJ jet but the flow chart was real choppy compared to the mukuni jet.

Naw I woulnd't ditch the DJ jet for another. They didn't show a decrease in power, but just the flow of the jet itself was poor compared to the other jets. The job of the dyno tech was to make max power and get the best flow he could out of the main jets. Normally the DJ jets flow fine in other models but the one for the foreman was very choppy. If you were a hard core racer then I am sure that it might matter, but for a normal ride you could not tell the differance.

Thats because my wife rides the rincon. Look around in my pics she rides the black beast. I only ride the bike to play around and go fast, I like my foreman in the mud.

hp torque

Was the 17 hp on the foreman at the rear wheels? What do they think the motor made without running through the drive train? Lastly what was the torque for the foreman. Thanks,
Steve

I have to find the sheets. With all the damage from the hurricane, I can't seem to find much of anything at my house now.
