That would be soooooo! much fun in an R on the dirt, knooby killer hehe.:eusa_think:

Wow....what a cracker of a result!!
Well done guys!!

:mbounce:

I hope to have a ride this Saturday.

I think an extra-long swinging arm and dolly wheels on the back will be the next mod!!!!!!!

That is big HP from a XT motor, I can't believe how much torque this build has produced. Well done Kris you have done well.

This dyno run is against my standard XT660X.

:077: Yes the next mod may need to be wheelie bars !
its a great result and heaps of fun building. its like riding a bucking bronco, it flattens off a bit after 180klms, but gets there fast (I think DL700's 5050 cam would help carry the touque past 6500rpm) have not wound it out far enough to hit the limiter in top gear yet but it will pull 94mph out of 3rd gear. All testing done on the track of course right Kev.

That's right all track tested, not ridden on the public roads at those speeds. :smilies0347:

I met up with Kris today & I have to say this has to be the fastest single cylinder motorcycle I have ever ridden, it just keeps on pulling & that 60 ft-lbs of torque I love it.

wow thats sounds great. can you ship that bike to sweden so i can try it out to see if i wanna make a mod like this on my bike? please :D

Have done a few more mod's

Now running a HDD5050 cam, kw valve spring kit.

Also have converted it back to ULP using a 12.5-1 cp piston machined flat top, still 105.5mm bore. Its much smoother down low with the lower compression and Ulp fuel, but the cam is crazy!! it pulls hard all the way to the rev limiter.

Also got a few other things to do when i get a bit more free time.
