HW needs help with Carb kit

[Hunterworks]

A minority of people are telling me they are losing top speed with our kit while their mid range and low end are much improved.

As I said this is a minority of people. The problem is I can't duplicate the problem here therefore I can't fix it.

What I need is someone who has the problem, has our carb kit and a air/fuel ratio gauge.

Does anyone out there have this combo?

I need them to do some field testing for me so we can figure out the problem.

I have your carb kit installed and I have your air/fuel setup also which I have not put in yet. I have had the same issues where my low/mid power was impoved but lost about 8 mph but I assumed it was because my jetting was off, which is why I bought the AFX. if I can help then let me know.

WOW perplexing problem. I gained MPH on the top end when I installed your kit Todd.

I am up to a 138 and 140, exactly what you recommended from the get go.

Hold on....am I understanding what you posted correctly? The 138/140 is the jet sizes? my HW kit recommended 144 front and 146 in the rear.

Bill,

Please call me at 1-888-626-7449 and we can work thru it. Thanks!!

JC, Magellan is at a different elevation so he would need the smaller jets.


Like I said this is a minority of people, most don't have this issue and we didn't have it here which is why I can't fix it without help from someone who does have the problem and a air/fuel ratio gauge.

I ride up to close to 6K feet. The HW kit calls for 140/142 for 3K to 6K and 136/138 for 6+. Todd told me the 138/140 would probably be it when I first got the kit, and I was saying he was right, that I am back where I should have stayed initially. Altitude makes a lot of difference. We ride from 417 is the lowest my GPS has registered all the way to 5K on a regular basis. Lots of fun, but makes tuning more tricky. With the HW kit, it is a lot easier, using the TPI vavles to help solve mixture issues by easily controlling the air.

Ahhh...got it.

I've got a tuning issue and I'm watching threads like this on rich/lean issues.

Actually the last tune change I made which was the fuel mixture screw in 1/8 turn...has help a fair amount. I still feel it's not running freely....like there is a lot more in it, and you guys are showing that. I just don't have the $$$$ to make it run that way. It also seems not all Teryx's are equal, be it stock, or the same mods.

guess i got lucky on this one,i dont have any issues with the carb kit

I still need a volunteer, Bill might be a while.

Mines doing the same thing. GREAT bottom and Strong mid then it falls short on top. According to speedo it lost about 5 mph. I have the dyna nonprogrammable cdi, hunterworks jet kit and an exhaust tip. Its jetted with the stock Teryx jetting specs and has a spitting problem at steady engine rpms. Moving the valves open and close didnt change much. Please keep us posted Thanks
