First ride with JBS

Just got back from mountain riding with the new JBS sheeve. It was awesome!  Never had so much fun on the rhino and covered way more territory un the same time. Nothing like doing Brody's on 27,s in the parking lot! so much more getup on tap at any speed.

My two favorite things about it are how quick it revs and pulls when you hit it and how the revs come down at higher speeds when you let up on it a little.  Makes a whole new machine out of it for sure.

Yup I damn near gave up on the Rhino until I found this Forum, everyone I ride with has RZR's and would leave me in the dust and then the magical JBS sheave put me right on their asses and now I love my Rhino!!
Where did you go riding?

Went to American fork canyon. Awesome fall leaves and only saw two other bikes. Best part was the fee station is closed! Free riding until the government reopenes.. Where do you do most of your riding? 
Yeh without the sheeve the rhino top speed lack of torque was getting old quick, It was fine until I'd go with a group of razors or modified rhinos and got sick of eating everyone's dust. Don't think ill be ahead now but at least I won't be to far behind. A big bore kit is def tempting!

Nice ride up there, Sunday we went to Knolls and of coarse it was closed but it didn't stop us lol we try and hit a different place each week. 
Last weekend was knolls the week before was Moab and the week before that was 5 mile pass, we hit the Bountiful mountain a lot because it is only a couple miles from the house but so far American Fork Canyon is my favorite next to Moab.

nice!!

Def not excited for winter! We hit bountiful trail last month for a few hours, wish we had more time as there was trails all over up there. Would like to head up there again before the snow gets to deep. Let me know next time you plan on heading up there and well try and meet up.

The wife and I will be in the Rhino and my son will be on his Sportsman, we are going up this Saturday for a while.

Sounds like a great weekend, don't forget more of your cool pictures.

I have a ton of pics that I could post but I always feel like I'm over doing it when I'm always posting them, just from the Moab trip I have close to 1,000 pictures just on my phone. 
We love taking pictures and also like to share the places we have been. 
Maybe I will start posting them on my Photobucket and just post a link to that so you guys can just look at all the pics on there or something.

that would be great

Hey Dusty. Are you running stock exhaust and filter and motor? What jetting are you running. I had a full exhaust I pulled off snd put the stock back on. Running a 162.5 main and stick pilot. Think its like a 40 or so. The bike seems to have lost some snap without full exhaust. It runs good overall but if I nail it from a stop there's some lag right off the bottom like a short blip before it then takes off and allows me to spin out 360,s. I recalled more torque right off the bottom before without hesitation. Wonder if in a tad rich. I've known others who I thought where close to the same jetting with stock pipe. Ya think I need a high altitude kit? I here those lean it out

I'm running the stock exhaust with a tip, Dragonfire CDI and a K&N filter everything else is stock. 
Not sure on my jetting I only bought the Rhino about 4 months ago, I'm sure I need to get it jetted correctly as mine likes to backfire a lot when I let off the throttle. 
I'm sure I could get a lot more out of it but while I'm still riding every weekend I'm going to wait until it's too Damn cold outside before I do any more to it. 
I have really good low, medium and high end and in low range it almost feels like it pulls the front off the ground but it's probably not lol
My biggest problem is I ride anywhere from 4,500 ft to 10,000 ft elevation and don't really know much about jetting.

On my old 660 I ran a 150 main 45 pilot and a/f screw 1.5 turns out. It ran great from 5000-10,000 feet

I would go with Sugarbear's suggestion and if it starts running better the colder, winter (heavy air), it gets try a 145 in the spring when it gets warmer.  That's what was working for me.  I'd even use a 142.5 when it got really hot.  That would keep the af ratio from 12.8 to 13.5 at wot.

Sugarbear..did you change the needle settings ? if so to what.. This is my next steep , doing the carb jetting..  Brewis :  was that jetting with the stock carb or with the 41 fcr carb? Danny

It was with the FCR, but I just looked at my records and it was running best with a 147.5 with the stock carb, but in July at 78 degrees.  Might start here or try a 150.  Hope this helps.

sounds good Scott..would be great to take it up to 10k..going to try to make a return trip to marysvale utah again next year...Danny
