so who is going over to dootalk to break the bad news that the new 850 just went from 173hp to 161hp, bring tissues.

how much weight could be saved using this carbon fiber plastic in the whole sled vs. current materials? does anyone have a current weight of a procross chassis without the motor? this has the potential to end the 2 stroke vs, 4 stroke weight bashing if its light enough. and if its patented than...

castrol super clean, spray it on, hose it off, works great.

it also talks about the engine being supercharged and the cooling running through the frame, and the entire tunnel being made of a new carbon fiber reinforced plastic material.

reading about how cat did not release a new 800 2 stroke that they were all waiting for because of a supplier/vendor problem, i think this may have been the best thing that could of happened. think about it, doo shows their hand with a bumped up 850 motor and 10 more hp, hoping to one-up the...

its a hiem joint the sp was short for spelling. the joints i listed can all wear and develop play. also check the ski spindle bushings.

with the higher seat and bars you have raised the center of gravity of the sled, most of it being you. you can lower the front of the skid, back off tension on the ski shocks, install a larger sway bar to reduce roll 12-13mm, and finally use more body english when driving it, leaning, etc.

when you say extension do you mean riser?, if so c heck that the 4 bolts are tight. if so then the slack is from the hiem-sp? joints, parts 25 and 26, and 45 and 46 and also part 29. each of these wear a little, but it all adds up to a lot.

2000 is too high, 1400-1600 is good and stops the clutch rattle noise.

jumping from 170 to 190 jets is 8 sizes bigger. spend the money on an o2 sensor and quit guessing. 105 is pretty lame and thats because the rpm is only at 10000. it has to run at 10600-10800 for max speed. many say the max should be 10200, but the radar gun says otherwise. my 05 is stretched to...

it must have happened recently or you would have lost oil and bearings shortly after. kind of hard to blame the dealer 6000 miles later. get a used cover off this site and locktite the bolt back in.

if you overdrive the clutches you need to gear down. you also need to set up the secondary to allow for more shiftout. my sled is geared for 112mph, but i have ran 115. not bad for a 144 rx.

had a t-stat go bad on my 03 years ago, would overheat in snow on lake at any rpm over 8000. fix the pinhole first but know that t-stat can go bad.

cat may make 4 strokes but not the high output type that suzuki or yamaha build. i can see these companys staying together for years, as long as both are making money. by sharing tech, both reduce costs and increase profit. cat has the most to gain, as their build quality should go up. by...

that is the same jetting i am running with just a modded airbox. the only way you will ever know for sure about the right jetting is to buy an 02 sensor. mine is ok with the 170 mains, but yours is probably lean. buy a guage and get it right. for now cover some of the airbox. these engines can...

the trophy will have a solid,well sculpted base, with excellect fit and finish, and the top will look like it was put together in grade 8 shop class and will fall apart when you close the door......... but its covered under warranty.

just a guess, but im thinking any damage would be the rail tips stabbing the track, eg. when you catch air and land on the tail, the front of the skid is driven down into the track. see if you have room to mount a set of wheels at the tips on a small shaft.

install an orange-silver-orange primary spring from yamaha in the primary. do this first before adjusting any weights.

the arrows point forward, and you should be able to read the numbers when looking down at the clutches on the left side of sled.

go up 3.25-3.5 inches from the center and mark it. draw a line to the points using a flexable ruler. cut with tin snips, it cuts easy. cover with edging trim if you can find it, i used black tubing cut lengthwise, as i couldent find trim anywhere. the shroud sits on top of the seat. if you have...
