450 Sheave Test Results!!!

Well if there was any question before if the JBS 450 sheaves makes a difference.......Well I put mine to the ultimate test this weekend!!! If any of you are familar with W.V. then I am sure you have heard of the "Stairsteps".....After a little liquid courage and alot of ragging from a RZR owner the 450 made it to the 3rd leg of the stairsteps. I would have gone all the way up but it was washed out and my buddy on the RZR had to turn around. For the ones that have rode around the Wagon Wheel in WV yo know what I am talking about!

Want to say Thanks

James and his wife are great! If you are thinking about a sheave, you would be wise to contact them. I have never dealt with any supplier ever who takes calls and works with you like they do. I messed up and lost a slider for my plate and they had another set coming for me immediately. I ended up calling James three times with issues as I am not a mechanic and had never torn into a clutch before and he was eager to help me every time. THEY ARE GREAT. By the way I had a trinity sheave in mine and went to the JBS and it feels like I do have better acceleration. I am going to the dunes next weekend and will have a chance to compare it with a buddys razor, to get an accurate idea of the improvement. He has a 4 seat robby gordon and would beat me 2 lengths. I will post on my results after this trip. I am hoping to be right there with him.

Starter clutch?

I read on an older thread that you stocked these? Still have them? I also have some other questions for you.

Thanks a lot! If I'm gonna order from anyone here it'd be you. I've read about your awesome customer service and wanna get in that!

Servicing the JBS sheave and od weights!

I put my Hot Rod sheave on in Nov. 2011 and have enjoyed almost a full year of increased performance thanks to James.
To date, I've put on 800km of varied riding conditions. Snow, lots of hills, mud, dust, crawling, lugging and WOT periodically. Rode quite a bit of dust this year, more than others.
Lately, I've been noticing a slight decrease in it's low end so figured it's time to service the sheave. Sure enough, there was a super fine greyish powder in the slides that were interfering with the sliders. Cleaned everything up, put back together and the performance is back!!
Just a heads up to guys who think cleaning out the sheave and sliders is too much of a hassle or too much work, it's definitely worth it! I probably should have done it after 600km as I started noticing a slight decrease back then.

One more thanks to James for his product and superior customer service to Hot Rod Nation!

Big Thanks to JBS

First off I have to say James you are the man,,,lol. I just got my first Rhino it was low miles but had set for over a year, Had a ton of issues wouldn’t stay running then it quit all together. I was going to take it to another local shop and well after the way I was treated there I was ready to part it out. I had some one turm me on to James which happens to be local as well. So I go see James and we decide on a few things to make it better , and the more I thought about it I want to make it go faster and faster . SO I work and bunch of OT sold some jeep parts , my Honda and my soul ,,,lol.
So here’s a run down of go fast parts J .
Big bore Kit, Cam and MSD
Full Alba Exhaust
Port work
Clutch Kit , Hot Rod sheave
Purple spring
Camplate
Belt
Card cleaned and jetted
Fuel Line kit Splash Shields
James was so helpful to me and explained everything like How and Why, I had never had a sxs and wasn’t sure I was even going to like it . SO after his hard work and time He called me and said Will it ready and runs really good. So I headed to JBS he took me for a test ride, Then I rode it. It felt fast and had a nice hole shot but I still wasn’t sure about the sxs world. I hung out at the shop for an hour or so petted some dogs shot the shit and headed back to Beaver only to get a call to hit the trails with a brand new can am 1000. So we loaded up and of we went. The can am is nice ,fast bad ass headlights, nice seats but all that comes with a pretty high price. Flat out the can am could take me BUT I will say this there was not a time that he didn’t look behind and there was the lil Rhino that could J he knew I was there and wasn’t going to be the guy that everyone had to wait on. SO after about an hour of his weak attempts to leave me we pulled over. My buddy says to me, I have had a Rhino WTF is up with yours lol it seems fast. I handed him the key and said here you go. After hearing my alba exhaust rip around the trails and 2 cold beverages later my can am buddy pulls back in and said WOW that’s very impressive. But with all that said I am positive now I love the SXS world and can wait to put more parts on it. Again THANKS a ton James. See ya soon.

thanks jbs

well we finally got the sheave in my dads 2012 700 sport all stock tires even. the speedo said 47-49 so from reading that looks about right. he is happy with the 40 mph engine noise now. i think he is gona be trying to catch my 06 660 cuse on gps im getting 53-55 mph but i also got a sheave and black rhino cdi. :banana:

JBS sheave

I was on my way to hatfield Mccoy trails and was going by MT. Hope and decided to give James a call about one of his sheaves. The cell service wasnt the greatest and lost the call so we just stopped in at his place. Not only did he hook me up with a sheave and radiator gaurds he took time out of his day to help me install everything! James is one hell of nice guy and knows his sh!t about rhinos. Gonna test out the stuff tomorrow and let ya know how it works. Thanks again Hot Rod!! You are the man and your dogs are awsome too.

Ordered my JBS sheave!!!

Y'all know when you talk to someone on the phone and you know you can trust them? That's how James made me feel when I called up to ask several questions about my sheave. Heck, I havent even gotten the Rhino yet, but have so much confidence in James' product, that I had to go ahead and grab one!

James, thanks for your patience in answering all of my questions! I know I will enjoy getting to report back to everyone what a difference it is going to make on my machine! You should have all the info in your paypal!

Jbs sheave and or vs msd

Well i first will say i have a 2011 rhino 700 with 14'' wheels and 26'' tires. Other than that all stock.... Im seeing 42 mph on my digital gague. I contacted nate at alba racing and ordered an msd 3d box for my rhino. I put it on a preset tune of #1 from msd and drove it i saw 50 mph screming..... Well last week i called james and he sent me a jbs sheave and clutch kit, tested it and saw 52 mph. I have removed the msd and ran it all stock just with his sheave and clutch kit and see 50 mph. So thats telling me the msd has just added 2mph? I waiting an e-mail back from nate at alba racing for possiably a different map? But these are my findings so far and i use this for recreation and hunting so reliability is of the most important. I dont plan on exhaust because i want the quiet factor and i might do a k&n filter one day but i was hoping for more than 2mph out of the msd. Any insight would be helpfull thanks fellow rhinoriders...

dont yell at me

ok so im pretty sure my sheave in my 06 rhino is screwed. i got a horrible vibration in any gear and also in neutral that goes away when the clutch shifts in. so my question that im gona get yelled at on is. does the dragon fire racing sheave any good? i know jbs is the way to go but cant aford the whole sheave now. give me some input please and thanks

jbs 686 rhino

Just got my rhino back from james after having motor overhauled. The work done was 686 piston, benchmark head port and polish, +1mm valves, cam, corillo welded rod/crank, all new bearings in bottom end, center diff geat support, and a dual muzzy exhaust... James did a great job putting this thing togather could not be happier. On paved roads uphill been running about 54mph on flat ground between 62-64... I also own a rzr s and let me tell you their is not much diff. Rhino will beat it in the holeshot, rzr will catch it in mid range top end is close to same... Just wanna say it again thank you james for all the work you did.. And give james an A+++++ on his motor building skills.. Pic and Video comming soon....

Getting ready to pull the trigger!

I've been hounding the hell out of James and I think I'm going to pull the trigger on a motor identical to his.Keep tuned in.I'm ready to make this thing make some RZRs mad.I'm tired of just being ol' faithfull with a ton of ground clearance and getting left in the dirt.

Rhino 450 with JBS Sheave + 14g OD

Hi James,

I continue to enjoy the JBS sheave in my Rhino 450. The 12g OD rollers have been working great. I'd say that for trail riding or any sport riding, that they are probably just about a perfect match with hard charging acceleration and great climbing ability.

Most of the time, my Rhino 450 sees farm duty. I put a lot of hours on it driving around the farm. Of all my farm equipment, my Rhino 450 get used the most and has the most hours on it. Actually, I'd say that I burn more fuel in my Rhino 450 in a year than I do with my big 90HP tractor. That's why I'm posting this to get your feedback. Figure I'd post it here in the forum in case it would benefit others in the future searching here.

Do you think that switching to 14g OD rollers or maybe even 16g OD rollers would make a big difference in fuel consumption on a Rhino 450?

Normally, I'm just cruising around the farm going from place to place to do different tasks around the farm. Sometimes, I do use my Rhino to tow some heavy loads. For instance, I use it to tow a 60 gallon trailer sprayer for spraying weeds. When I tow the sprayer, I need to go slow in order to get good coverage on the weeds. I don't know if 14g or 16g rollers would really mess up my ability to go slow (<5mph) while towing a heavy trailer sprayer. What do you think?

My primary goal would be to save fuel for the farm duty, but I'd still like to be able to tow heavy loads and climb big hills for recreational riding. I'm hoping I could run with heavier rollers to keep my engine RPM's down in HIGH range (save fuel), and then if I needed to tow a heavy load or climb a big hill, that LOW range would still give me the ability to do so. I guess I'm looking for the best of both worlds. I know that there will be compromises, but since 90% of my riding is done around the farm, then I'd be willing to sacrifice ultimate performance for some fuel savings.

I figure I'd ask the expert and see what you think. Have you tried 14g or 16g rollers in a Rhino 450?

Ed

PS. I'm running with stock size tires.

Talked to James today(JBS)!

Also the cell tower is down so his phones are not working and again please be patient and he will return e-mails and calls as soon as he can..

Another Satisfied JBS Customer

I just got my Rhino 450 back together today with a JBS Hot Rod Sheave along with the OD rollers. I had my Rhino out of commission to put a new set of rings in it (was burning oil and smoking badly).

While I was working on it, I decided to also work on my CVT. I found the primary clutch components badly worn. I decided to replace all the components and thought it was a good time to upgrade to the JBS sheave. Glad that I did. Since I follow the "run it in hard" break in procedure, I was doing some hard acceleration and deceleration to help seat the new rings in the freshly honed cylinder, and I was impressed with the acceleration of the new sheave and rollers. Top speed was good too. I was just driving around on my own property, but at one point I hit 40 mph on my gravel driveway. I do have a Dynatek CDI. I haven't taken it out on the road yet to see the true top speed with the OD rollers. Acceleration is very good. Punching it from a standstill, my Rhino launches very nicely now and accelerates briskly with the JBS sheave. I'm very happy with it so far. I'm also happy with the fact that my Rhino 450 is not smoking badly any more!

I'd highly recommend the JBS sheave. Great product and great customer service.

Needing some install advice..

Starting the install on my 700 with the JBS sheave finally, I had a couple of questions that I figured I would answer before hand.. The Sliders and Weights are greaseless that I know, but is there anywhere I need to grease specifically besides the obvious? Pretty sure James told me Ultra-matic grease only, I got that, just wondering where exactly? Sorry for such a dumb question just looking for tips and tricks from the pros! Thanks!

Belt Rub Cover with JBS Sheave?

I'm looking into getting a JBS Sheave for my Rhino 450 based on the great reviews that people have on it and Jame's service.

Any of you guys out there with JBS Sheaves have any problems with the belt riding so far out that it rubs the CVT cover?

I know that some of the other machined sheaves have this issue. Just wondering if anyone has used a JBS sheave long enough to see if this is also an issue.

Thanks.
