High Compression Head Wanted

(Click here to view the original thread with full colors/images)



Posted by: #8trx450r

I need a high comp head for a DRX50 Water Cooled, Higher than the DRR " High Comp " heads that only make 135-140 PSI. I'd cut one myself but I do not have the machining to cut the O Ring grooves deeper, Let me know what you have and how much you want, I'd like to have it ASAP if at all possible.

Thanks

Have you considered checking on the use of a thinner bases gasket?

This would lower your ports for more MX useable power and also increase compression (if you could still maintain squish clearance)


Or removing some meat from the bottom of the cylinder?

With the cylinder I am using now I do not want to alter the port timing from where its set so a higher comp head seems to be the only option at this point unless I check the squish and have enough room to cut the "Top" of the cylinder with out reducing the squish too much.

We have a configuration that we use that makes 185psi on the water cooled 50. without too much work. PM me for more info.
