www.overstockpartsgalore.com... 1015cc Kit w/ Cyclinder: OMR

I know this is a dumb question, and it's probably too late anyway given the great deal, but are these J blocks?

Mine isn't and not sure if they offered...

Contact them, they we're very prompt in returning my e-mails...

Ditto on the promptness. It took Gary at the site just a few minutes to confirm that they had J blocks. This is looking more and more like a no brainer for my particular project. New pistons are a must (#1 broke in my hand while being cleaned), but the block is at the shop being mic-ed now. Should know soon if it requires bore or hone.
If I order a kit, is there a reason not to get the largest over bore size available, assuming it's just for a daily-driver type project?

Totally up to you for what you're wanting to do...

For me, this was a no brainer, I'm 49 (soon to be 50). I don't need the fastest bike out there nor do I plan on racing this bike nor do I plan going 140mph. Just wanted a dependable & strong running motor.

Above the 1015cc on a KZ900 this would require grinding of the case for the cylinder sleeves and this was something I just wasn't interested in. I also had the option to obtain a 1000cc cylinder, again, just wasn't really required.

I figured for the extra 60cc, just wasn't worth it to me for what I require.

Basically I needed a cylinder anyways due to broken fins. If I used the original I would need to get it bored & honed. Hell, basically got a brand new cylinder already set up so I actually saved $$$ this way.

I ordered the 1015 kit on Tuesday. I'm doing a little second guessing right now on whether this kit is a "drop in" for my '74 900. I haven't gone to the piston website yet to find out.
OMR, how long did delivery take on yours? I'm not in a rush for sure but would like to know anyway. Also, I've been thinking about ignition systems as the advance curve surely should be different with the higher compression. Back in the day, I ran the stock advancer set up and didn't have any problems. I had all the goodies in that motor and it really ran strong. Still, I've got to wonder what 30 years of technology could do for this motor. I've looked at the Dyna programmable system and they have a curve for 2 valve, high compression motors. That's it for now, ride safe, Steve

~ 5 business days... UPS Ground but you can have them use a faster shipping at your costs of course.

For everything I could find in researching this subject this should not be a problem....

Old Man Rock, Thanks for the lead on the engine parts. I have a 1075 piston kit and block on it's way next week. The timing for this was perfect.

I am glad you found a good solution.

Also, thanks for the link I found the perfect gasket set for my GPZ's and its cheaper than the Ebay ones:)
