That's almost an exact copy of the R65 Mono torque curve, it dips between 4,000 and 5,000 too. That's it's cruising range and seems to have no effect on performance. I think the R65 Mono just uses some sort of stock cam.

Interesting statistical analysis by the forum soft ware.

It counts 9 votes when there are 10, and 111.11% of those voters have an opinion.

I'd think a 20% drop in torque in the middle of the useful rev range would be quite unmistakable and not at all welcome/acceptable.




btw, What's "asymetrical" or "symetrical" about these cams from Moto Israel.

Different durations on exhaust and intake lobes rather than the same duration for both.

Hi John,

the software counts and displays 9 different voters and shows the percentage of voters agreeing with a vote.

Greetings, Rudi

This is an interesting Trace series, if you need more info, pipe in. I think it's good to notice the significance of this pic

Those graphs have to be from the valve, not the cam for the amount of lift.

I still don't understand why some of you guys that have actually bought some of these cams don't ask for specs with a 2mm lift check point so first off you can actually check your cam timing and secondly so we can compare specs with BMW's 336?

Just curious, what is stock valve lift on an airhead? Anyone know?

Yes I am trying to help. I am very much in the cam market and would love to see some USABLE info. That I am sounding like a broken record because so far we haven't seen much useable info. Most cam comparisons START with comparable specs. No I am not trolling. There are a number of us here that have a lot of experience with 336's and would love to have some comparable specs. Plus there are a number of us that have 320's and whatnot that might want to time their cams, or maybe even compare them to 336's. To do that in any repeatable and meaningful way tuning wise, you need specs with a lift check point. There was that ONE guy in the cam thread that said he was going to come up with some for a couple. He hasn't shown up again yet. It IS a lot of work!

Should I start playing with your name? It is against the rules I believe. It is a lot easier than coming up with comparable specs, that's for sure.
