Just 'cuz I said it don't make it right. Make your own informed decision and you'll be happier.
That's the theory, anyway. ;)
My preference for the 200 is a Pro-X for a number of reasons. They are available in different sizes to fit your bike. True, .0005" (The difference between the alpha designations) isn't a great big deal, but as long a you're taking the time to rebuild your bike, why not get what fits?
Wiseco doesn't offer that.
For whatever reason, the oem piston in the 220 just seems to keep having problems. That's generally why Wiseco is the choice in that case.
BTW...if you order a piston from Kawi you won't have the choice of which size Pro-X you get. Generally it will be a 'B' in the box. You will need to order it from a Pro-X source to get the alpha designations. There is a chart listed on the forum with part numbers for different sizes. I'll try to sneak in another chart...not really decent to take up the space, but a quick search didn't find it and I don't have it bookmarked.
**edit***
I can't waste the space.
CLICK HERE for the chart.
It's in post#12.
**edit summore**
In the above thread the subject of discussion is an '89 200, and the chart displayed in that thread is noted as applicable for that year. It's the same piston/chart for an 'H' model. If you have any question, verify the PNs thru Pro-X's website
