New big bore thumper stuff.....

This week at the races, i was pitted next to Rick Peterson from RPMsBigBore since it seems we have a mutal friend.

It was a good oportunity to check out one of Ricks new big bore kits. He is running a stoker big bore 302 kit on the new KXF/RMZ four strokes. As we all have heard, these bikes are running way hot even as stock so you might think a big bore on these bikes is asking a lot.

What Rick has done is made his own cylinder! a very simple idea where a outer cooling jacket is machined from billet and the inner cylinder is fits inside as a removable sleeve- a similar concept to the two piece heads that we have seen on 2 strokes. the cylinder setup has been dubbed the "IceCube". Right now, they are racing this bike everyweek and really hammering these things hard to try and blow them up, its not until when they have good reliablility that they go up for sale to the public. For this reason i dont think some of the kits for the CRF250 are ready yet, but i am sure it wont be long.

cool stuff indeed.

a picture paints a million words!

Hey go easy guys, rent aint cheap out here!

LOL- are you saying i am cheap! :) :eek: :joke:

In all fairness, i think RPM is aiming at the Vet market, they are the ones that spend all the money, right? its obvious you coulnt try and run this at a sancitoned event. My friend raced the bike in the pro class and liked it a lot- his normal ride is a CRF450, but used to race a yzf250- he said the bike had the benfit of both spectrums ie lighter and good handling but the power with the bigger bore keeps it in the pack with the 450s.
