Someone please fill me in on how you even get the idea let alone do it.

The other question is why? Why go through all the trouble, performance wise it will not measure up to say a Puma or Saber...and the amount of work and cost is higher than using cylinders specifically designed for the 250R.

Why? Its cool to be different. Not everybody wants to have something somebody else will have.. It looked like the guy in the post above had a bunch of time involved, but it also looked like he was WELL under the price of a puma or saber. Cool read anyways, Id like to hear a ride report. How much is a Puma cylinder?

 

Isnt max pec on here getting some one to build him one?

 

I'd like to know how much machine work was involved... Or was it relatively similar in design.
