Today Mohan and Yew came down to do some testing. The battery was flat so we hooked it up to the car for a jump start. After the direct injection of some fuel it fired up but ran ragged and would not rev up. Increase the rev and it would sputter out. So some carb work to be done.
We also checked the radiator. After the initial burping it settled down. Water (no coolant) can be seem circulating nicely. No sign of piston induced pressure. So the radiator may not be the problem. Overheating could be the thermostat, fan switch or the fan itself.
The oil from the dipstick looks OK. No sign of water contamination. Conclusion - water from engine water jacket not getting into the chamber. Gasket may be leaking but not badly blown. So the PO's, "Head gasket gone!" may be an exaggeration.
When I went to inspect the bike at the PO's workshop the mechanic there told me that the bike needs a "top overhaul" (I don't know what ever he means by that) and that would cost between $2,000 to $3,000. I may yet have the last laugh. Like I always say, 'Wish me luck" :-)
All smiles after the test.
The engine is covered by a rubber hood and a plastic heat shield. So we still cannot see the leaky gaskets.
So everything came off - fuel and water hoses, carbs, rubber hood and heat shield.
Lots of oil on the left side of the rear cylinder.
On the right side both cylinders shows signs of leaking oil but not as bad as the left.
Later we removed the rest of the Tupperware including the Trunk and the front wheel cover.
The difference between Japanese and German design. To access the engine on the BMW only 2 huge pieces of plastic needs to come off. For this Japanese bike, it is more like 30 pieces.
This is getting interesting. Plan of action.
Clean the carburettors.
Remove and flush radiator.
Remove and test thermostat.
Remove and test fan.
Remove and test fan switch.
Then re-install the carbs
Clean up the engine and run again to pin point the leak.
Now to go looking for parts to buy. Things are looking up. I am optimistic.
Stay tune for the next episode.
