That's cool,I was showing a buddy those last week saying we have to get some because they looked so good.I needed more cdi's and just ordered 5 of the super charged those cost 95 bucks U.S. plus 35 for shipping then the exchange and duty is almost 200 Canadian so jugs will have to wait LOL but I really do want to try them!I like that the transfers can be corrected much easier and the bridged exhaust port will allow much more width to be used safely.
I am going to have to break down and build one for myself as well. Problem is my bike is running pretty good, and I hate fixing what ait't broke.

Hey @gary55, is that a stock muffler on the end of your outlet tube there?

If so, is it gutted and or did you keep the cap with the little outlet tube?

I've thought of adding a gutted stock muffler just to lessen the cackle, if that'll even work i have no clue :D

Are you still using the SBP pipe?

Have you tried any of the G4 cylinders? A guy came in with a 100.00 Ebay kit and bike last week. It had the G4 cyl. I built the bike for him and it ran like a beast right out of the box with no mods. Had 4mm of blow down, open partitioned transfers, Af80 rod, tall jug/ 2.779" with single base gasket and type B piston. The intake and exhaust ports were large and clean. Clean casting. I was quite surprised how well it ran.
Have you seen the g4 bottom end on ebay? Looks like a Super Rat with the 3 bolt timing cover and has the integrated cdi. Wonder if it has the larger crank bearings. Don't know much else about the SR engines but might pick one up.

Here is the Junker Columbia Klunker with KX65 pipe reconfigured and modified to use the SBP pipe first divergent cone.
With the 40th rear sprocket it has crazy low rpm torque and hill climbing power like crazy.
Tops out at WOT around 34'ish and just pulls like a clydesdale :)

My intake manifolds keep cracking every winter.
This winter i decided to make an intake manifold out of a muffler flange and tube. (Larger inside diameter)
with the exception of a little 4 stroking everything seems to just clydesdale along at low speed, pulling uphill even better so far :)

Will post pics tomorrow of intake.
