[volks_r_us]

From the stop sign in french, I can bet you a $1000 that this guy is in Quebec Canada.
Probably built by him or Arsene Racing

Id like to see/hear more about this motor. Is it expensive? How many mm's is the bore?

[puma]

this bore 82mm polaris piston very expensive motors 3500 for this kit.

Puma can you post of anymore photos of it, is it still running strong?

[jadleybray]

I would say the cost is comparable to the Puma. Rotax cylinder and head is cheaper, but you have to incur the cost of moving the studs in the cases. Everything else is a wash. Prior to the puma, the rotax (and earlier PSI) were the cylinder to have until you stepped up to the Saber. This one in particular runs very hard.
