Needed!

i need 2 no cylinder heads for a 98 honda rs 250, preferably suitable for leaded fuel, anyone got a pair kicking around they may want to sell?

The bike will run fine with the leaded gas and unleaded heads but you might want to check out VHM heads and inserts. Then you could change the cylinder head volume with the gas and also for changes in temp.

Check out this link for the HRC tuning notes and it will give all the settings required.

I have used both heads on my 125 with leaded gas and could tell very little if any change. it was just as fast on the topend for sure.
