finally the new crankshaft has arrived I bought a c100 one witch has 51mm stroke now all I have to do is to machine a longer pin but there is no hurry about my v twin because I decided to build a single for this frame and start another more serius build for the v-twin and since I want this bike fast I will go the cheap way

 

[ducaroso]

so this is the cheap way

For some reason, your pics won't open out on my screen. Is it the R7 AJS we're looking at, as in this pic?

Occasionally an exposed pushrod engine cane lose one when the valves float a bit. There are two ways around it if you want to retain the old fashioned style. Either carry spare pushrods with you, or do what Gnome Rhone did with their licence built ABC, and have couple of discreet retaining loops to catch it when it bounces free.

What a truly amazing bike build thread! Your work on building your own engine is downright inspiring.
Wonderful! - I'm fascinated to see how your engine turns out

Is that a microlight aircraft engine? It certainly is very nice
