Nice link, but it does not reference '96 anything.

My question still stands.
Wireman? How about it?

not directly no, but the 96 does fall into the cop bike section which are all J series motors

The second is the 1000J, or "J model" as it is called, and was built from 1981 until present ( currently only available in police motorcycles)

read it again;)

81-97 j-motor should be interchangable with 81-82 1100 with 17mm pins.people have been building big inch motors out of them for a long time,i just prefer the 73-80 motors myself

im guessing that APE might have some info somewhere on what interchanges for sure;)

I think it's actually 81 to 2005 (last year for the cop bike?).
According to APE Jay he has put 100's (over 100 anyway) of 1075 J kits in the cop bikes, so I'd guess it's safe to say they will interchange

My mistake, 82 was the first year for the J motor in the 1000P, it was a year behind the rest of the 1000's.

or whatever size they actually were,they tend to round things off! although i have noticed you can put 900 emblems on a bike with a 1327 in it !:evil: while the topend is apart with the pistons off try dropping the cylinder down on there to see if you need to clearance the cases for the sleeves;)

:huh: you really think the bottom of the sleeves will hit the crank? have you heard of this happening? thats what you mean right?

OH I c what you guys are saying about the cases, thats something I can do right? But it seems like it wouldnt be that much of a difference between the cases. I'll let ya'll know in a few days.:dry:

and the heads are the same? or do I need a kz1100 head?
I bought that 1000 j head assuming it would fit with the block. Geez Now i'm really doubting it will work.

I got a GPz1100 block in my Z1000R2 (J-engine) fits OK, no boring of cases and head fits also. When ordering head gasket order one for a GPz1100. J-engine as far as I know was used in P-models for ages and therefore parts should be interchangeable.

But IMHO there is no point in just assembling tose part. At least you have to hone and re-ring pirton but I would definately bore to 1109cc (Kaw´s 1st OS) or some wiseco kit. IMHO when you open the engine fix everything as good as possible.

81-82 KZ1100 head is the same as the J head, the 83-84 1100 head is different and much sought after, a 83-84 1100 head will sell for ~$600 or more on eBay, while a J or 81-82 1100 head will sell for ~$200.

Some people have said they stuck a 1100 block on a J without doing anything to the cases, while others have said the needed to clearance the case bores (commonly with a die grinder or dremel) to get them to fit, my guess is it depends on whether the case bores were bored to the high or low end of the tolerance range.

I just measured the diameter of the 1100 and 1000 J sleeves at the bottom of the two blocks I have, the 1100 is 78.64mm and the 1000 is 75.74mm according to my digital caliper.

On a side note, the 1000 J block has been bored for a 1105 kit, and it's easy to see why Jay (APE Jay) does not recommend the 1105 kit in a J 1000, those sleeves are really thin :woohoo:

awesome! I was having doubts about the head matching the block, just thinking about the size of the sleeves and the size of the head chamber. :blink:
