I also like the rangy bikes over the docile throttle responding top-enders. We had a little episode where the creek crossing washed away, so out of a pebble and clay creekbed we had to get up a 10ft virticel and hit a 4 ft wide cattle gate at the top, then carry on up a goose-crap slippery 45degree ...

the trans is the same 88-92 subframe is 87-88 only. Its longer because of the shock mounting (which is higher than the 89+) you probably like the twisting of that knob on the rear shock, that you;ll loose going newer. The wheel would work by swapping bearings and parts. use the caliper from the matc...

people totally forget about timing curves, timing can be the single largest non evasive performance upgrade on a naturally aspirated motor. I am very pleased with the '88 cr250 cdi I installed. Oh, so you guys know, even though the '86 stator coild were only '86 for the 500s, they were '86-'88 for ...

talking about saving some power in the drive line, my guys all ran ernie-glide trannys when they could, dropped all rotating mass, and only coupled the mainshaft to make it drive, brilliant trans, had a 3" od clutch in it to get the car off the line. another trick is using a trans with a ballsp...

Yes its the complete surface of every gear, poor manufacturing is what makes a wear pattern in the gear, If parts were made accurate there would only be a smooth surface. Anybody who's blown a trans or clutch where material has gone thru the gears can see how they "lap-in", that was the ol...

This whole headshake thing is someting thats been confusing me, Me on an '02 250 and my bro on the '04 250 always felt like the bikes rode loose, even looser than the 00's. Then once we rode the 500's we realized just how bad those af frames did headshake, Dad got on the 250 after having a flat on t...

find the right year... '89+ should work. the tranny gears were widened in '88 so you might have issues there and the cases will have to be machined to accept the jug. Plus the '85 is a short rod motor, so you would have to get a jug spacer from cometic. You could probably make it work, but in the e...

In our testing MR-pro2 is 3hp in a tuned ktm125 2stroke
and MRpro4 made 4 hp in a ktm250 4 stroke More than using u-2 or u-4. Thats some sweet pour in power! Ktm canada and honda canada are going to try and use it exclusivly until the dammn '09 no leadded fuel rules get here.
