Hey everyone! First off, thank you all for your input and advice. It has been super helpful. The old thread was getting kinda long and I have changed so much on the ped that a lot of the advice (although useful for future knowledge) was no longer relevant.

Here is the deal for you that are new to my issues....

I have a 1 HP newprt and a 1 hp maxi. I have put the maxi aside for now and am working on the newport solely. It came with a 12mm carb with 52 jet and 12mm intake and a #2 cylinder. The cylinder had a small metal ring inside of the trapezoid intake port as well as a longer piston skirt which covered up the intake at TDC. It was originally geared at 13 x 45, and would do 20mph and sounded good, and has great compression.

Latest mods are as follows:

I have popped out the restrictor, added a 14.5 mm intake, 15mm bing carb, high compression head, shortened the skirt to fully open the intake, added a bi-turboo exhuast and high flow air filter and changed the gearing to 14 x 38. The 15mm bing came with an 82 jet which we have decided was way too big. I have 66- 72 on order, and they should be here soon to help out with that issue. I currently am running my 12mm bing with a 64 jet and the 14.5mm intake, which is perfect. The 62 was too lean, and the 66 caused 4 stroking.

To make a long story short (too late) My ped still only goes 25 - 26 mph with the current set-up. Shouldn't I be going way faster than that? I have not touched the timing or tried to port anything yet. Thoughts, comments, statements of fact?
