Dale, We have spoke before on the phone and you told me the reason behind using a car dyno to load the Atv. If my memory serves me correct it was because you said it was the best real world load of running up the hill for a good 8-9 second pull. Your bike was set up to a t to run Q. Congrats on that. But answer if you like or maybe Jerry can. If your bike makes say 70-80hp on gas moving a 3500# roller why did it only run mid 50 mph up the hill. And why didn't you run anymore the rest of the time? Just seems weird to drive for hours to make one pass and than drive hours back home.


For clarification on the banshee. I called mat to confirm what it was. Its Toms 100% 425+ # pump gas duner banshee. Not a bad duner either.

And whats all the talk about this other "stock" JH hall bike that was racing when in fact its a 3 mil spacer plate big bore "stock" motor.

Chris,   I'm not sure this covers what your questioning here but...Yes I prefer to tune on the car dyno,  I like the heavy load and longer time duration because I feel it equates more to the riding I do.   Your in the ballpark on HP #s and roller weight...as far as speed..thats the best I could do with that setup I guess , I didnt know that was the goal..did you do somekind of math and think speed should be more??
 I have run that exact setup for 3 years (except for rear suspension) and have rode it beside many of the guys on here at Glamis.  I ride it for hrs through the dunes.. It runs consistent 56-58 mph passes on Olds.

 The bridge broke out of the intake last season,.. trashed things up pretty good, we cleaned it up and I'm running it with no bridge  (didn't want to sleeve it yet, only 88 bore)  which will certainly shorten piston life.  In the process I lost about 3 hp someplace..between new head and cleaning up port gouges.   It still runs pretty good as you saw.
After the race I sat down to drink a water and my son hopped on the same bike and made 8-10 passes with all the other guys on the hill.  He doesn't ride often but had a great time in the mix.  I think he won a few lost a few...My hybrid didn't get much time at all in that afternoon and I wish I would have run it more,..Its actually faster than the small reed bike but is very light and quite a wild handful coming out of the hole..only +4 swingarm,  and even with just 8 paddle haulers.  Big reed, Long Rod, and a little KX piston... way different power curve.

I have a much faster bike but the word was duner bike racing only,.. gas,.. 57" wheelbase type bikes per RK.  I had planned to bring it to show off but couldn't get a last minute ignition issue to straighten out when we gave it a spin on the big rollers...... I was out of time.

The black LT belongs to a young friend of mine Aaron... He is adding performance as his wallet allows. He bought the motor from a friend.. its got a 2 mil stroke, long rod, and runs a Lt piston which is tall so needs a big spacer under the cyl, he just added the 44 carb that trip,..I loaned him a HPR 19 pipe off my other duner.  His next step is porting and he will have a good runner.  It has great lowend as everyone saw.. runs out of breath about 6500 rpm,.. but still he beat most of the bikes there (LT's)

I told RK and the others there I'll be in Glamis this coming weekend if anyone wants to come out and ride/race.  Going out Fri night, going to camp on the flats.  Company Welcome..!  I'll have the same bikes.
