Dieco I dont have one of the cylinders with the slots cut in from the exshaust port to the transfer port. I havent even seen one of these so i cant to a comparison on this type. Do you have any pics of this I would like to see it.

I agree with you on the older style engine witht he single runner intake transfer ports. This engine or on mine at least has a much higher compression head than the newer one with the two ports per side. unfortunatly like you say the older engine has the single ring piston which is pretty lousy. In my opinion so far the best set up is to find the older engine and then get the new style two ring piston to put in it.

I didnt get the magnets yet as I havent had a chance to get into town. I checked on my order status yesterday and it says its all on hold till they get the 8 servo extension wires i ordered to. man i hope that dosent take to long. I want my stuff lol.

I am going to try and find some thinner shim stock today and experiment with the reed vave set up.
