Thanks, Matt! Yeah, air leaks can be really frustrating. It can already be frustrating on a single-cylinder Lambretta engine, but with a twin, it’s twice as frustrating and means more than just double the work. That’s why I wanted to show that you can also do it in two steps-I hope this approach is helpful for anyone working on a Chimera. 😊
Yes it makes complete sense to do it whilst part built. I would love to build one, and maybe one day when I can afford one I will. It would be a dream come true.
Better to spend the time now than when it's all built up. I've raced 2t motorcycles for years and if there's ones thing I've learnt, it's do the leakdowns. This way any problems with power and running can be attributed to other causes. Great video.
Thanks, @nbodge3693, for your observation. If you look closely, you'll see that the bearing was also packed with grease, and you’re right-normally, oil should be used. However, since the bearing was thoroughly cleaned afterward, I don’t see any issue with it. Of course, using O-rings is also an option-thanks for the tip! Feel free to check out Part 7 to see how the situation develops. 😉
Another great video, nothing worse than chasing air leaks. But a great feeling when you finally see the needle holding pressure 😊
Thanks, Matt!

By chance have you used soapy water on ther drive side bearing??? 😵
use Viton O-rings on bottom of cylinder studs before fitting the barrel
