So after 4 years I finally broke down and bought a stock sled!!
A definate departure from my full tilt 1500cc triple IQR's.
My idea for it was to put my new billet twin motor in the chassis that I am making.
Before the install and testing of the Big Bore 1100 twin for the PRO RMK...
CLICK HERE...I wanted to do some development of common sense bolt on upgrades that will give real-world improvements in the performance of this motor without breaking the bank.
First... The Power addiction 13.6:1 compression ratio head was developed for this motor for use at 5000-10,000 ft... There is also a 12.5:1 head for 0-5000 ft. Other custom CR's can be done on special order.
This cylinder head is designed to run on premium pump gas.
After installation we instantly picked up 20 lbs of compression from the stock 110 lbs to the Power Addiction head with 130 pounds. This head features a much more efficient combustion chamber design than the stock head. Improvements in starting and transitional throttle response, top end power as well as "bottom end grunt" were clearly evident.
Second, I contacted Scott at HPS about his new lightweight silencer. I have to say the fit and finish are top notch and shows the American made quality that he his know for. I really like the sound from this can and it complements the head very well. It drops about 5 lbs from the stock sled weight and frees up some space in that area....This silencer (can) is priced at $339.00
Less than 1.5 hours later I was done with the install and off to the Mountain to see how it all worked.
The throttle response was second to none. I can't believe how much better the throttle response compared to the stock 800. The head plain makes the sled "feel" much better from a performance standpoint .
Anyways, NO adjustments were needed to sled and NO programmer was installed. Still running pump gas.
I will be working on some new clutch setups. I really don't think the clutching will need much from stock. I feel the primary needs a different spring and I will be testing different clutching combos this weekend.
The head in the photo is a Complete Billet Head assembly that is offered for $440.00 with the anodized cover..
A "Cheater head " that retains the the appearance of stock is $340.00 which uses your stock black cover .
Custom laser engraving may be available on special request for an additional fee and a little lead time
Our testing shows shows significant improvements in performance that the rider will quickly see.
