1985 GPZ900 Motor
« on: November 12, 2016, 12:16:28 am »
So I answered an ad for a zx900 motor of the 85 vintage being sold for $50. I don't actually have any need for it as I don't own a GPZ900 but I figured if I could talk him down to say $30 bucks then why not and that's what I did. I've always wanted that bike and maybe in the future I can find one that needs a motor for super cheap. So what do you think guys? Worth it?

Yep $30 total. He claims it came from a running bike though I question that because he parts bikes for money. I would think if it were perfectly fine he would know it's worth much more than that.

Maybe a go cart build? :)

If not for sale then maybe a donation? :)

If you haven't already check out a YouTube channel called glassglowz. He does this sort of thing and has a great series on a microburst build.

Head, cams, carbs, clutch, gears, will fit a Connie, and if I remember right, the 900 had smaller combustion chambers...  >:D

Not too sure about the head to frame mounting.... id have to pull boxes down off the upper level, and compare, the 900, the 1000, and the C10...
But when I bought them all, iirc, they differed... the guts were what I was after anyways. :rotflmao:

I have GPZ900 36mm carbs and rubber manifolds, intake cam, steve's 7 degree advance on stock exhaust cam, bafflectomy, and coil sticks. I like the power increase and performance. For what you are paying I only got the rubber manifolds. Steve gave me info on carb jetting, needs a different needle, I got mine from some old CB900F Honda carbs that work perfect.

If they were actually off a 900 you need to measure those carbs.....  iirc, and I have some sets, the 900 had 34mm carbs, the 1000 is where the 36mm units first debuted.
