I have seen that problem many times, and have seen people throw money at trying to fix them and still have head gasket issues. After head, head mod, gaskets, piston, bore, you are getting pretty close to the same cost as an ESR 310 kit. Would be better money spent and you would be starting off on a better platform without the headache and down time.

Just my 2 cents. Regardless, best of luck

We've been modifying OEM & CollHeads at BDT Motorsports with two high temperature o-rings for >10 years with no issues or leaks. Many Racers & Races have won National 2 stroke classes (both Trike & Quads) with o-ringed OEM Heads. When setup correctly; absolutely no leaks, and better than a head with a gasket IMO.

As far as cylinders go, IMO to this day the most reliable cylinder is still the Honda OEM. A properly setup OEM @ 67-69.5MM bore x 72MM stock Stroke will run with any 310 aftermarket cylinder, while keeping the original Honda OEM quality & reliability.

OEM cut "Pump" or Race "Gas Heads" with two sets of o-rings for all sizes from 66-69.50MM are in stock at BDT Motorsports. Your Head can also be cut & o-ringed for the appropriate application.

Don't want to upset a few or break .NET rules with advertising prices. If you can't find someone to do the work for you, that's a different story; then BDT is here to help. PM sent Justin...
