Thank you, Andy !

Worked on this bike until Sunday, 3:30am, which means it was a long Saturday night !

All relevant things where checked and made good. We have found a lot of failures and loose screws, so we had to check nearly everything.

Engine started when we bought it and it started late Saturday night. Just engine revving, no riding. Suddenly it stopped working. Ok, we went to bed then.

Checked the typical things on Sunday:
– Fuel is coming out of the fuel tap
– Removed, cleaned and checked the carb – ok
– Removed spark plug to check if there is a spark
– Pushed the E-starter button (as there is no kickstarter built in) and WTF …

What is that for a big fontaine coming out of the spark plug hole ???

Well, we found it is a mixture of fuel (1:25) and engine coolant !

Ok, removed the cylinder head and found it was not fastened at all.
Even more worse, the O-ring seal between combustion chamber and surrounding coolant “jacket” was wrongly mounted, partially pressed and destroyed.

All that allowed the coolant to enter the warming up engine.

Just ordered new gaskets/O-rings, turned the engine several times by E-starter. The fontaines became more and more less/low and we dried everything we could reach as good as we could.

We will see how this goes on after reassambling the gaskets and cylinder head correctly.

BTW: We found beautiful ignition sparks at the spark plug 😉

Cheers, Michael

PS: We hope to do the Sella Ronda in the italian Dolomites beginning of October with Nils on Aprilia and Maria and me on our Twins.

Nils as my pillion and me did it on our way home from holidays at Garda Lake (Lago di Garda). He is very impressed of the Sella Ronda and wants to do it on his own bike 😉

Pic shows Nils at Sella pass this Friday 28th Aug, wearing my jacket and featuring Maria’s LTD we have used for the trip.
