While I now have to wait for my tag, was busy today safety wiring a few nuts and bolts as "vibrator" may be her 2nd name..... :goofy:  150cc 50's engine, as expected I guess...

 

Note that this is NOT up to USAF/NASA spec, but one deals with the holes presented....

Had the engine running for a wee while, rode up and down the close; then the engine started to run like shyte. Misfiring, poor throttle response....   But, better now than late at night on the Bridge between Denmark and Sweden I guess.... :tongue: @keny

 

 

 

Can you guess from this picture what caused it?

The points are directly wired to the battery and it worked fine so far..

Main culprit is the piston rings, causing too much pressure inside the carter....  to be continued!

Old skool racer carter vent

But she's an alpha female alright, marking  her territory

IMG_20200601_154602_DRO.thumb.jpg.47aeda0d083b7794cbca29aeb6c91495.jpg

 

 

Piston rings remain suspect, the vent smokes quite a bit. Like a 2-stroke.... 😞

The main leak atm is the oil seal behind the clutch basket.

Busy afternoon...

 

 

With the Gilera engine's piston rings most likely shot, I started on the spare "race" engine. Splittjng the cases to fit the (removed by a PO) kickstarter.

 

It dawned on me that both being 150's, it could be simpler for now to swap heads. That would get me back "on the road" quicker.  The worn head could then go for a refurb/rebore later. 

"those in the know" are verifying if this a straight forward swap...

 

 

"Virginity can be cured

Today I removed a piston from a conrod for the very first time.  Painlessly :tongue:

 

 

Raining today so the wee garden shed had to make do

Helmet.....

 Which helmet to wear while riding the Gilera?

 

 

The Mamola replica?

PSX_20200605_154237.thumb.jpg.3f4873844ce00681f57f8801743e139c.jpg

 

Nah...  Too modern...

 

 

 

Which definately rules out

The helmet is the right image but it's a nice face. And all those teeth. Are you sure about that choice?

Front sprocket is rivetted solid to the clutch basket, so you use it all....
