Russ Collins parts/ designs are still making fantastic results!
My K6 cam has RC295 scratched under it's washer. The best cam it has used. Civilized and wild when needed. I doubt I can find anything better.
And you can still get the same camshaft new today.
The DynoMan DP295 cam is the same camshaft and gives great power throughout the range.
Yes, Dynoman keeps the RC heritage alive. I bought the DP315 that same engine had for a while.
I tested other cams during a few days in my K6 1005cc. Megacycle 125-25 and finally a used a mystic cam I found on eBay USA. The seller did not know which cam it was.
I found RC295 scratched on its side under the washer. Data of RC295 matched what I saw when I timed it. I used it with old NOS RC836 pistons to start with. Now Mikes Billet block 1005cc .
Huge improvement! It pulls really hard from low all the way up. Good idle and response in general. I have not tested the CX-7 cam with existing 1005 cc, 836 only, it came more after 6500. I guess the DP315 and 125-25 are designed for higher CR like 12.5 and more.
Russ Collins made a perfect cam profile (295) back in the days that can continue to make our CB750's happier.
