Best low end-mid pipe for 98 kx250

Goat:
I was thinking about going to my driveline shop and buying a couple bearings to cut apart and see what the balls weigh. BBs are a good idea as well. I have seen some in ceramic at some point but not sure what they would weigh compared to ss. Copper coated ones would probably be ok but I think those are too small in diameter. Airsoft might last for a minute but seem to be too light.

We just got another 8ish inches of snow last night. Time to bust out the kdx/quadracer with paddles n skis :P

All good ideas/thoughts...I never thought of the ceramics, they'd probably be quite a bit on the light side compared to ss.
Just starting to flurry here.

Goat. Interesting idea.  Post your findings.   I took apart a spare mechanism and the ramp is built for the 5/16" balls only.  So if a full swap is not available then I suppose I could remove material off the ramp and accommodate a larger ball.  That would be 2nd worse case.  Worse being cant make any moves

ok. same size, that i also want to go ..  could the stock head gasket being modified? 

on my 360 engine, we had to made an o-ring for the outside and a copper ring on the inside.. there is very less space to the studs like you could see it in the pic. left is the 360 with 78mm bore, right is 03 250 cylinder...
