I have a few MT's modded by Richey and Palmaris Racing. We use 30% fuel 8 to 12 % oil, with McCoy mc8 and mc9 plugs, they run real good in the 240 temp range.
Also for you guys having problems with Powerline K parts. I placed an order Sat. and it said in my cart that nothing was in stock. I got conformation from them today that they shipped the complete order, So I dunno???
