At the former rebuild they used a BOGUS gasket set, the footer gasket was very sticky and it took us an hour to remove the footer gasket and cleaning the surfaces. Due to the BOGUS gasket set the cylinder head gasket leaked EVERY WHERE. When installing the barrel ALWAYS use the FOUR O-rings (and NOT THREE as in the former rebuild) on the footer gasket, even when it is a blind hole.

Three different colored spark plugs, the center sparkplug has the right burning proces.. There is something wrong with both: ignition timing and carburettors.

Cleaned the greasy groundplate of the ignition points. Also replaced the ignition points by new points, adjusted the opening of the points on 0,35mm. No we didn't adjust the timing because there is something wrong with the cilinder head gasket. We really NEED this one to be replaced. (later on)

The cause of leaking the brake fluid is found, the seat of the square O-ring for the brake pisten is very rough due to corrosion from the past. We will advise the client to replace this caliper by another one.

Some rust on the piston of this caliper. This means brake flued was leaking.

It was hard to remove one of the M10 inbus bolt from the front brake caliper RIGHT side, what's wrong with it. After disassembling the complete caliper we see that both O-rings on the bolt dispappeared and are pulverized. How is that pssible. Of course now we now whta caused the blocking btrakes.

SITE UPDATE 19082025: Started today with removing the front brake calipers. We noticed that when pushing the bike you needed a lot of force for that. A short test confirmed: Blocking calipers, so clean and in case off rebuild.

All three carburettors cleaned and ready for assembling. And NO, when you don't do it this way with the RIGHT adjustments and jets in the carburettors the GT engine won't run properly and you can start again with celaning the carburettors. You will understand that a leaking, filled with fuel, float is not OK.

Disassembled the complete carburettor block for rebuild. Found a couple of defect parts: a leaking float. The carburettors haven't had a rebuild before, the old 45 pilot jet and the 107,5 main jet's were still inside.

Inside the carburettor is also very dirty. This means (done a lot of CV carburettors) at least THREE hrs of cleaning and polishing.

Never seen so much corrosion on the brass parts of a carburettor. I think they used WRONG FUEL as E10 (Euro 95). Always use E5 or Euro 98.

Although the float bowls are not extreme dirty the carburettor itself is very dirty with corrosion and OLD FUEL residues. These carburettors aren't cleaned for a long time. NOTE: This carburettor block seems to have less wear.

SADLY, the empty oil lines are those lines where they have exchanged the check-valve connections itself. Nope we can't repair this any more. We will replace this oil lines by another refurbished one with SIX new check-valves.

And YES, leaking oil lines at the chack-valve connection. Someone did a bad job. The connection from the check-valve connection hose to the oil line hose itself was loose. QUESTION: How to repair now? The oil lines are very rare at this moment. Try to find one?

Noooo, someone tampered on the oil lines already! When the check-valves are defect we can't change these anymore, because the connection is now different.

CAUTION: Always be sure that the 2stroke oil hose is making the right smooth turn, so NOT LIKE THIS. It is possible that the oil hose will be closed in total, so the engine don't get any 2stroke oil in this position. See a servive bulletin of SUZUKI: OIL STARVATION.

See the picture of the electrical starter engine: When you use 10mm2 on the electrical starter engine its's mandatory to use also a ground wire of 10mm2 from the battery to the frame! This ground wire is much to thin, yoe can see that at the connector it has been very hot already.

We ALWAYS DRAIN the engine FIRST when we get an unknown bike at www.knalnaarpotz.nl. This because we know that after more then 50years the check-valves in the oil lines have defects. In this case NOT OIL but a lot of fuel in the LEFT and CENTER cylinder, this because of OLD and leaking carburettors.

SADLY, they used the wrong bolts for installing the exhausts. The nut on the small exhaust pipe is M10x1,25 (metric fine) so you should use a bolt with the same threading and not with standard threading. The threading in the small exhausts are now damaged. Besides that, the bolt is much TO LONG and can hit the swing arm.

SITE START 13082025: A Suzuki GT750-B came in at KNALNAARPOTZ shop for some repairs and large maintenance. We will repair: Electrical starter, oil-lines rebuild, oil-pump rebuild, cylinder head M10 bolts leaking, rebuild the front brakes and much more also safety repairs. 29082025 After we did some work on this GT750 we discovered that the engine needed a complete rebuild, this because the former owner ran the bike with RUSTY cylinders, so all the rust damaged all the bearings of the crankshaft.
