Fitting the 1100 (1089cc) block is common practice for a cheap upgrade if you can get a good set but maybe not so if just starting with the s/h pistons.
If you get the cheap 1100 pistons you will still HAVE to buy new rings, circlips, and possibly wrist pins and then the gaskets etc. (all of which are included in an MTC/WISECO KIT )
The price of those OEM parts will not be far off or will most likely exceed the price of a complete new MTC or Wiseco kit and you still end up with a less than perfect job with std comp part worn pistons and no significant performance increase.
False economy.

After looking into these unknown make pistons, I could tell they would be low compression at best and the only advantage I could tell was the displacement increase they would provide. Given the time, cost of boring, gaskets, etc, it would have provided little performance wise and in my book a waste of money. Add to that if a ring was broken while installing them or a miss hap while running them, no replacements would be available. The unknown origin and history also made them a gamble IMO.
Riding a motorcycle is dangerous enough and using CHEAP parts is just asking for trouble. IMO :whistle:

Recently I paid $60 for boring 4 cyl Toyota block. Maybe bike block needs steel plates attached for boring.PLUMMEN wrote: $50.00 or so a hole for boring that gets ya.
