Pro Rmk big bores?

Hands down rk TEK 858 kit. Awesome service, can't beat the price, and runs real smooth and plenty of power
 
Has anyone dyno'd a Bikeman 860 bb? They are claiming 182hp.
If its actually that much hp,I will be very surprised.
 
Rktek and bmp shouldn't even be mentioned in the same thread, the comparison isn't even close.
 
I hear from a little birdie that Northstar in Preston ID also has a kit that will be available soon, if it works like their drop in then it will for sure be a ripper. Carls's Cycle makes a hell of a kit and so does Brad at PAR. I would put the Carl's kit and Brad's kit light years above RKTek and BMP.
 
Riding a PAR 910 this year. Still working on tuning, but seems to have potential. If it wasnt for me breaking trail, and their track poching, my buddies on their new XM's would never see the back country, at least not the high parts anyways.:face-icon-small-hap
 
I have spent some time on the Carls 900 adnd my buddy has one. These motors are dialed!! It pulls harder than any other twin I have rode(except the 1140 twin) and the throttle response is like no other. I would say is is comparable to a 800 turbo at 6-7lbs. Great package!!

Carl's 900 is very impressive! There is so much torque, and hard pulling power to there set up, it is just completely unreal! IMO this motor is a deep snow, technaical line, pulling dream! A true turn key, gas and go monster. I wish there was more days in the week to ride it!!

Give Carl's a Call and let them give you the run down, ask for Jack himself or Chris in Performance!
 
I have over 400 on mine with no issues. I check it before every ride, it looks flawless! A little story, I ended up in a tight predicament, I was wide open trying to push the sled down the hill to keep from smashing into some trees. I had to grab the brake and lock it up as I was WOT, It pluged the tunnel. As I was trying to save my sled from tumbleing down the hill, trying to get the snow unpacked from the tunnel by using Rev. then forwards. I ended up wasting my clutch drive delt.

I was sure I had messed up the QD belt in all this, toke the covers off to inspect the QD. no problems with it after that rodeo. IMO so far I have jumped hard with up hill landings, flat on the troutle landings, smoked Clutch drive belts wit the extra HP and so far the QD has held up great.

just a note I do have a spare just incasea!

completely happy with the combo of HP and the QD.

That might be the dumbest thing I ever read. Good luck selling that. Sign a contract - are you F'in kidding me!

You should consider the vipec, Brad and I have nailed the tuning for the 910 setup :). I'd love to be able to help you out, and I can tune it remotely :)
 
We ran with 4 other stock pro's over new yrs, and the fuel in the stock pro's was about a 2 to 3 gallon difference by the end of the day.

What I seen was my sled did not need to run as hard to get into the area's we rode in. In short they had to run WOT way more than I did. My feul was used when we stoped and played on the hills, which of course I used more.

All in all there is not a huge difference, I may use my extra gas by the end of the day, when a stock sled would not use theres.

I do know, from a long night of experience you will not go the same miles as a stock sled in a all day over the hood adventure. LOL you will need those extra couple of gallons.
 
because we out west are not hot rod trail riders or lake racers!

Just funen!! :boink:

Dan has a great rep!

I'm well aware!! :face-icon-small-coo


Something to look at is that while the 900s and 910s are animals, they cost around double what an 858 or 860 does. Not starting an argument, but just something to be noticed.
 
Now that you mention it, what is the coast of 858 or the 860 from the other reputable motor kits?
