Each tooth you go up on a front drive sprocket is supposed to increase your top speed by 10%. Ryan's shop Rdm sells 11 tooth and 12 tooth drive sprockets for around 50 bucks a piece.i think you can get them for 40 dollars apiece on eBay at his store on there as well. Also i heard mzmiami sells a 11 tooth drive sprocket for 25 dollars as well.

I think he's just trying to get rid of all his old inventory to make room for new stuff. Because I highly doubt he made that big move to a new shop and bought all the expensive machinery just to not go through with his plan. But I could be wrong because there is allot of upset customers of his out there and I'm sure the stress from all that is killing him but all I can say is I hope the best for him because I kinda like the guys intelligence when it comes to these bikes and the bikes and parts he makes are top of the line.

If you want to do that, go big or go home and do what I plan to eventually do. Buy a cdh 110 bottom end and build a 56mm MS660 based saw engine and have a 98.5cc beastie.
Hey so what all do you need for a bottom end to install a phantom 85 cylinder. You have to have a connecting rod that's made to fit a 12mm wristpin and needle bearing like a zmn100 connecting rod huh. A yd100 connecting rod won't work well it.

He brought all that misery upon himself due to his associations with Ethan Smolik as well as the infamous Robert Bianchi, Zeda Mafia and Zeda Motor Sports infamy...Non delivery of parts bought and paid for in over a year or more etc. etc. etc.

All three of them would close up their businesses and work shops for a few months at a time and go to the races together with their bikes etc, not giving a damn about their customer base as reported many, many times here in the forums.

Very bad business manager and customer service follow up with our forum members as well...This is why all three were removed from here.

I will let @ImpulseRocket answer that one for you as he has hands on experience with both these motors.

The ZMN100 rod is ideal, but there are also AF80 rods with 16mm small ends to accept the 12mm wrist pin bearings. There has been a couple of people that have also just bored the small end of a 14mm small end to 16mm to accept the bearing, and as far as I know are working ok.

The most difficult part is just getting your hands on the 16mm small end connecting rods. Beyond that, the bottom end is just a yd100.
