tentative honda cr430 big bore kit from eric gorr coming soon

[Jeram]

The Polaris 800 went to a powervalve about 8 years ago and has never looked back, gained power across entire ranges.

These cylinders which are between 2002 and approx 2006 will most likely be the ones he uses because:

They have a modern port layout
They are non dfi
They have powervalve, one of the best non servo based valves you can get!
The stroke matches the cr stroke better as its only a couple mm shorter (hence the 30cc gain). Whereas the next later model had a short stroke and ones after that went dfi

I was / am looking at putting one on a bighorn 350 bottom end so did my tease arch on the Polaris 800 efi cylinders.

So total it up:

clapped out cr250: $2500
EG open class kit    $2500
revalve work:         $800
new tires, grips, plastics, wheel bearings, steering head bearings, shock bushings, air filter, seat cover...  $1000

Then the bike costs about $7000

What does a new 450 cost?

Am I nuts with this back-of-napkin roll up?

Yes you maybe, But motocyclist's have never been the sanest bunch.

Sanity is a relative term. Still, to get essentially a modern, light, good legs, good handling, open class two stroke for 7k? Sounds pretty competitive with the current crop of 4T bikes on the current market. 'Cept for the pros of course....
