Thanks for the responce!
I don't worry about the fuel cause i always put 100oct. and find it everywhere!
The barrels have been measured when i did my last overhaul and are the same.(luckily)
I believe 0.2 skimming isn't a big deal, is it?
But youre right i dont race the bike and want to do plenty miles with this motor.
Ok you have convinced me i'll just fit one stock rear head.
Thanks for not letting us newbies destroy our motors...
