GPZ 1100 - first of many questions
Posted: Wed Nov 27, 2019 6:44 pm
Hi,
Today my new GPZ1100B1 US import project arrived.
It needs a shed load of work and is an open book to start with. Exactly what I wanted, I didn't want a simple tidy/restore job.
I'm very familiar with my Z1000A1 but never had a GPZ.
I've just spent some time out in the garage bonding with the bike and my head is full of questions.
I'll start with the engine
It's a non runner and converted to carbs
I was thinking of starting by getting it running but bearing in mind the engine will need work anyway this could be a waste of time - maybe ?
I've done a compression test. 3 are 100 PSI the other 120 psi.
So at a minimum it's the removal of the barrels and top end where everything will be measured, checked and replaced where needed. If it needs a re-bore I'll go bigger
My question is, should I check anything else before removing the engine and if I don't should I do a complete engine rebuild to be sure. I guess otherwise it's a risk that I'll put it all back together and have a bottom end, clutch, gearbox etc issue.
For example, I went to check it went into all gears. When not running it goes from neutral to first and back but not to second. I'm guessing this is by design and it won't go beyond first unless it's running ? (the Zed thou ain't like this )
Any advice on the approach to take with the engine will be appreciated.
Thanks,
Jim
