See if Race Logic has templates available for you engine. I bought their templates for my old 580 and am pleased with the product and results. There is not much to worry about with polishing, but just remember to keep it to the exhaust side, don't try it on the intake side.

A easy mod for the ZR500 & ZR600 is to double up the base gaskets and remove .018 of off the head surface. Add a set of twin pipes and they come alive!! Its hard to only grind 1/2mm off the transferports as the nicasal is that thick!!

Never heard that before but, I could see where you could have some gains. I would recommend having an experienced person do the porting unless you're really good with a die grinder. Re-plating is expensive. Honestly for the price you'll get more power from a pipe than porting. Either way you should tweak the clutching to realize the maximum performance.

If it don't go, chrome it!

Or bolt on my ZR D&D 720 top end clutch it and pipe it and you have yourself an animal!! But I found PSI pipes work the best on the 5/600s and word really well with the 720 over D&D I found.

Sure did, worked great. But it didnt feel like it made nearly as good power it did in the ZR chassis. Put is pulled and in the works on my 03 EFI F7 motor to be dropped in.
I just pulled the trigger and getting Northern Crank shop to build me a stroker crank so I can use newer 800 polaris or cat pistons for the 22mm and have Kaw 67mm stroke rods to make a 760. He said they where great motors and mine has been one for me but finding pistons were a nightmare, and the wiseco's didnt hold up well at all. I think iam going to put the motor in my S2000(ski doo) chassis that I plan to use to water cross.
