BTW:
As a gasket set use the VESRAH ones.
Do not use Athena ones ! -

Hi Kenny,
the big bore set was offered to me after I have asked a lot of engine reworkers to do that for me, but it was close to impossible !The needed parts are not easy to get and the closest pistons (Ducati) still need some rework.
Find a report with some details of another modified Twin:

This is how the piston surface should look / feel like:
right hand side is a stock piston (78mm), left hand side is a big bore piston (86mm).If it has a “burn-in”-hole, it should still move up and down, but may end up like the poor one.
All the best !
Cheers, Michael

Did you expect that the weight of the inlet and outlet valve is close to be identical, even with the inlet valve having a larger head diameter ?
About 80 grams each.
BTW: Valve stem diameter is 8 mm for both valves, which is very solid.Did you know, that the exhaust valve is made from two different materials ?
Tested it with a ball-shaped…[Read more] -

Well, this was sitting in the garage unattended for a long time.
After checking what would be the next steps I finally decided to get some new or modified camshafts !
There is a company called Megacycle in the US that do that modification, but I have found a company called CAMPRO in Germany and they offer the same modifications.
Lower Price,…[Read more] -

The rear light and it’s holder is welded to the frame in new position.
Looks good.Engine is out of the frame and is already blasted with dry ice (carbon dioxid snow?).
The result is pretty awesome and the cost was below 100,- Euros.Don’t have good photos on hand, just one of the separate blasted sprocket cover.
I am sure you know, how the…[Read more] -

Thank you for educating me.
I have to admit, that I haven’t seen or eaten a Crumpet in my live yet !
Well, I have to go to Yorkshire to meet up with you and get invited to eat a Crumpet and have a brew 😉
So long,

Single carb conversion is/was often done with the Z400/Z440Twins.
Haven’t seen it with a Z750Twin. -

I can’t find a proper translation for crumpets.
Pics at Google show a smaller, big one (which I don’t know) and larger, flat ones like Crepes.

Hi Kenny,
the complete engine is 78 kg !
Remove the valve cover first, that eases the job.
Having the bike on side stand is not too bad, as you have to remove the engine sideways to the right.
Fix the chassis against rolling away. (Strap on hand brake, etc.)Cover the right hand, lower frame tube prior to engine removal with cloth to avoid…[Read more]

Hi Phil,
I have used the wheels, brakes, front fork and swing arm of exactly that model (Z750GP, 1982) to built my caferacer based on a B1 (1976) frame.
Fits perfectly.Cheers, Michael

Michael replied to the topic Glemseck – thinking aloud in the forum Progress Reports 9 years ago
For sure the two outlet pipes in the “bell” are mounted this (stock) way to achieve a spin of gas within the bell.
If you use an external breather bowl, direction of outlets can be changed to streamline the gases into the bowl.Remember, we are talking about 750 cm³ to displace air out of the crankcase with each rev of the crankshaft. And to…[Read more]
