I got a set of 65mm stock stroke about 2 weeks ago and let me tell you these things scream. Calvin is a personal friend of mine and personally put my motor together for me. They got put on the sandtrax's dyno jet dyno about a week and and a half ago. I have cpi inframes, vforce, stock carbs, 5 degrees of timing, 170lbs of compression, and .065 squish. Still running a little fat(cold nights) and it made 78.9hp and 44lbs of tq. You probably are going to pick up very little from port work because if there was much left in the cubs they would be cast that way but you might get a little. Going to a 68mm will give you some more and a 4mm would help even more. But let me tell you that stock carbs on this cylinder is killing me because they flow so efficient they need a big carb like 36-40mm. We had to jet my bike way down to get it right because the cylinders were sucking the stock carbs main so hard it was running way fat. Sandtrax told me a good set of 38mm would probably pick me up 10+hp....???89hp stock stroke and bore on 100 octane lol????..... pretty impresive!

 

As far as dans dyno goes I dunno. Sandtrax said that his dyno always reads a little high but everybody tells me that sandtrax dyno always reads low soo....

I didn't say he recommended them, that is just what I have. I have been impressed with my shearer inframes, so more than likely I will try a set of their out of frames. FTZ is close to me and if I can get them to cut me a deal, I might try a set of their pipes. Dan also doesn't recommend 36HV carbs, but I am running them. You don't have to do exactly what your builder tells you.

Your right, but when your struggling with something it sure takes a lot of factors out of the equation :)

I think lonnie was more impressed after he rode it but he said he would have like to see the hp numbers a little higher but the tq numbers were huge 44 is what a 4 or 7 mill will make. The problem I see with lonnie, and dont get me wrong he is a great guy, he almost acted like he didnt want to help squeeze ever hp out of my bike like Ive seen him do on his own motors, why, because and this is just my opinon the cub is direct competition to his port work and every porter thinks he is the best porter. Why would you spend 600 dollars on a port job and get 65-75hp when you could spend 875 and make 90. Calvin really opened up a new market with these cylinders, they will allow alot of us that will spend 800-1000 and still use all of are parts that we've already invested in and make huge numbers where we wouldnt spend 2000-2800 on a full out cheetah and have to waste all of are parts we've already invested in.

Granted under ideal conditions (larger carbs and a better ignition) these might make close to 90-95 hp. I dunno anybody that can port a stock bore stock stroke stock cylinder with stock carbs and ignition to make 80hp and 44ft/lbs.

I dont know why he acts like that, he seemed that way when i took my passion motor up there,he is the closest dyno so ill continue to use him and it helps me to go up there and get my bike jetted close, i dont know what the big deal is he will be dealing with the cubs also, Was yours just bolted on or did it have a clean up done on it.
