you have a 900 block on 1000 cases? check the engine vin and see if it starts with z1 they are 900 cases, kz means they are 1000's.

correct, my case starts with kz and my block says 903.

there are kz 900's doesnt matter if its a 1000? the piston size is what matters

are there any benefits or downfalls to having a 900 block in a 1000 case?

not really, the obvious slightly less power but unless u want to spend a lot of money to change it back i wouldnt worry

call Z1 enterprises Mon morning and they'll hook u up

I understand that the case size doesn't matter it was more to satisfy my curiosity than anything. I was simoly going to say that if you really want to you can open up a 900 block almost as big as a 1000. My brothers stock 900 is opened up to a 1230 with a stock head with stage 2 porting.

i just got my head back from pit stop. no porting, just cleaned and sealed. i am hoping my bore/piston meas. is ok so i can just throw a set of rings on.

The blocks are almost identical except for the obvious bore differences. The sleeves in the 903cc block can't take as much bore as the 1015cc blocks but are otherwise pretty much the same. The only place you might have some issues (that I can think of) is where they mate with the cases. On 903 cases you have to bore out the area the block sits in to use a 1015cc block. I don't think it's a big deal, but you now have the opposite problem, cases that are bored for 1015cc and 903cc block which means there will be extra material removed from the mating area.

Be Smart.... Measure the pistons with calipers to be sure it hasn't already been bored before you order anything.

i got cha larry.

Joe.. not sure if you still need these measurements....

sorry for the quality the manual would not sit flat to scan so i took camera shots and re-sized...click on the image it should be readable ,sorry it is so shitty...
