How much fun was getting the motor in? My Suzuki engined Magnum was like one of the Chinese puzzles you used to get in crackers at Christmas. The only way was to lower the frame over the motor, twist, tilt, turn and prey. Never taking that out again! Really easy tbh, lowered the frame over the engi...

Engine in the frame and forks fitted. Apologies for the quality of the picture, it was late and a bit cramped lol.

Yup, had the engine soda blasted to remove the old layers of black paint and then ended up spraying it in the back of me old Maxus van as the garage is full at the moment lol, makes a handy spray booth tbh

So, take two, engine assembled with new gaskets, valve seals etc. just waiting for the cam cover gasket to arrive and it’ll be time to put it back in the frame at last.

Just found this after a quick search

So it may be that I have to omit the "o"rings with a Cometic gasket.

Sorry, forgot to mention scroll to the bottom of the thread

Cheers Al, I'll give that a try, think I've got some machine washers knocking about, I was just a bit concerned about squashing the "o"rings a bit too much and restricting the oil supply.

Quick question folks. I'm just about to refit the cylinder head on my gpz11 with the 1135 big bore kit and I was wondering if the four "o"rings that sit in the barrels on the outside studs should fit under the head gasket or do they sit through the head gasket? The outside 4 holes in the n...

Sorted

I'll definately give Debbens a ring zed, that looks just like the kind of repair I need doing.
Thanks for the help, very much appreciated.

Here's a picture of the head.

If it's a B1 motor then a 'J' head will fit or any with a full hemi (non bathtub) 70mm combustion chamber. Having 'B' engine numbers does not mean it is B spec as the cases are the same as the unitrack and the internals are interchangeable. You need to measure the gudgeon pin diameter as only the U...

I assume I can use either a Unitrak head or a B2 head ? Are there any other's that are compatible? No. Unitrack head has different (steeper) exhaust valve angles to the B2 and all the others. If you have a unitrack bottom end (18mm gudgeon pins) you need to use the Uni head unless you want to get i...

You could try and give Ray / Steve Debben a ring and see if they can do anything with the threads. They really do know what they are doing and if it can be fixed they will be able to do it. Not seen anything they couldn't fix as yet. 01425 474628 AL Cheers Al I'll give them a call tomorrow and see ...

Looking for a Gpz1100B2 cylinder head please or anything compatible
Cheers

Unitrak head will have a boss on the rear by No.1 inlet for a temp sensor. Big Sert's may help, but will depend if the hole is doweled or not. Buying direct from the US worked out cheaper for me. Snapped bolts could be spark eroded by a good auto engineer. Great project! Looks like it’s a Unitrak h...
