Are they worth the money? Single jets are cheap but these kits come with more than just jets. I am looking to get all I can out of the new HSP pipe/header and K&N on th HO.

 

Personally, I don't think they can be beat. You pay for the time they spent working out a lot of the details so you don't have to and to me, that's worth a lot. If you have loads of info from other guys that have spent time doing what you want to do go with their suggestions but if not, it's an easy way to up your performance. I've done them on my Wolverine, my boy's Warrior and my Rubicon and have had nothing but positive results.

 

I think my Banshee ran a bit better with the DynoJets.

I don't think they're worth the money. You still have to tune your machine, and instead of having commonly used jet numbers that everyone can understand and make suggestions on, you have dyno jets that mean nothing to most of the tuners out there.

Also, you still have to tune your motor! you can't just send someone jets and say they will work, elevation, fuel, mods, weight, tires, gearing, temperature...they all come into play with jetting...so in reality, you're not gaining anything but a headache. Stick with stock style jets.

 

I have had real good performance from the jet kit that I installed on my bayou. I know if it will enhance the performance on my bayou 220 it will definitly improve your quad. The only problem that I see you will face is in the altitude. Like Dill said a difference in elevation plays a heavy roll on the jet kit. They supply you with three different jets for different altitudes. Mine performs really well done here in Florida ( elevation 35 asl, 22 abl ) The same jet may perform a little different around Tennessee or Kentucky even though I would still be in the same elevation for it. They need to give you the numbers in between the jets that they supply so that you can buy them if you need to, just in case you are on the border-line where the difference in two jets are.

 

I don't think the $45 kits are worth the money. I can buy 14 main jets for that at 3.11 each. The reason K&N/Dyno kits use funny numbers is so that you have to go back to them for help instead of going up or down a jet size for $3. Of course the jet kits will work ok, but as Dill said, you still have to tune your machine. You may be close with the jet kit, but more than likely not right on. To pay $45 per kit for the research that goes into is crazy-it's not rocket science to switch out jets until your bike runs right-it only takes about 5 minutes to change a main jet on my Mojave(if the plastic is off-which I left off until I got the jetting right). I took me about 1 1/2 hours (including plastic) to get mine running great. By the way I get my jets from Parker Yamaha 18006728778 for $3.11 each. And if anyone was wondering the Mojave comes stock with a 132 main jet(I had that question some time ago and it was hard to get an answer w/o taking my bike apart first). I'm sorry this is so long, but too many companies are making us pay too much money for parts already for me not to voice my opinion about this.

 

Thanks all for the info. I think I will try the rich winter settings and go from there. The stock jets are cheap and may work just as well if not better than the kit.

 

I should point out that I am only using the needle jets in the Banshee.

Pepprdog,
Was the installation on your wolverine easy??????
what setting did you use? Clip Position
what elevation did you use???What size jets????

Thank you....
