Hi guys need some information. Have been reading your threads about adding a JBS clutch system to your Vikings. So I would like your thoughts as to how I should proceed.

Currently I have 27's on my viking with the stock 12" wheels. The tire's are the Interco Radial Reptiles and are a "All Purpose Tire" ( very aggressive treads.) I can still run 50 Mph with three people in it, and have no issues getting around. I don't plan on doing a lot of modifications except for going to 14" wheels, and 28" down the road.

So can you guys break down what the real benefits of putting a JBS system would be ? I would be getting the whole kit which runs $720 at JBS.

Thanks very much

What does the whole kit consist of? I'm interested in this also & plan on going to that same tire & wheel combo.

Guys, this is just my personal opinion, join up on the hotrod forum and post your questions over there. Almost everyone on that forum has a JBS sheave and the guys are very knowledgeable and helpful. James is on there quite often, there is a Viking section and a lot of the guys from here are members over there as well. This way you can discuss your riding style (mud, street, trails etc..) and the size tire you plan on running. To buy a kit on-line without discussing it with James is a mistake. Let him design the kit around your bike.

As far as the benefits go, they are huge. Slugging the wet clutch makes it engage sooner and makes the bike much more responsive and eliminates most of the whiplash experienced by the engine brake. As far as the sheave and weighted sliders go, it will depend what you are looking to do and your riding style/terrain. Quicker acceleration and better mid range power are the benefits to this. I lost a lot of power going to the 30's and I lost top end. This was all fixed with the sheave.

There are several of us that are still trying different springs and experimenting with different weighted sliders. James is recording all our information along with his own testing, and he does A LOT! Every bike is different in the way it is ridden, terrain, weight, diver....the list goes on and on. At the very least, go over there and do some reading before you do anything.

I put one in my VI because it would power out when fully loaded stopped vertically or buried in thick mud. So far been out once with it no issues. Running 26" mud lites with 2" lift, dealer suggested bigger tires wasn't worth the weight/ loss of power. I'd have to agree for here in Alaska it gets steep n deep plenty of winch time

I've just put on 30x10x12 ITP Blackwater Evolutions (36lb) on STI HD Beadlocks (15lb). Running 18gr OD weights in my JBS setup and WOW what a beast, Hi2 H4 L2 L4 just loved it in every gear. Got up to 88kph in Hi2 and I could of got some more I think but I didn't want to find the limited just yet. Was using the same weights with the stock wheels on last month and same top speeds. Cheers
