It is fair.Caferider said:I dont think "too cheap to make right and left handed pistons" is fair, why not make a piston that works on either side?
After all is said and done even with the extra machining Im still happy with the old hap Jones Piston and I'm still ahead of a what new set of 650 pistons from italy would cost.
Whoever puts the pistons in their engine will end up with less compression than the stock 600 piston would give, so they are not true replacement pistons. With the extra valve pockets they may not even give any higher compression than a standard 650 flat-top, and may even give less power because of the odd surface for the flame front to travel over. With the larger surface area exposed they will absorb more heat, and I already mentioned the extra sharp edges they have.
They were probably pounded out on a cnc tape machine in Japan and they did not want to spend the time to make two tapes and two setups on the production run.
And as far as being ahead what a new set of pistons from Italy would cost, that will only be true if the budget pistons give the same power and don't seize, distort with heat and run like crap.
