Off with ‘is head!

Standard

While I’m waiting to hear about availability for the Hercules bits I need, I’ve turned my attention to the Scimitar. The heads need to come off as the posts holding the rockers are being pulled out. They’re only an interference fit and unfortunately have started to move. I’ll get threaded inserts. I don’t mind the work, but I’m not really a car fan – I’d far rather be working on a bike.

Bob dropped some more light reading off the other day. I’m particularly interested in the balance factors different manufacturers used on their flywheels. Anything from 30 to 70%! The chapter on Balance and Torque reactions in P.E.Irving‘s Motorcycle Engineering book is fascinating! Though having said that, I’m no nearer to deciding what balance factors to apply.

I really like designing stuff, it’s so easy to make changes when you haven’t built anything yet!!

The photo shows the rockers on the Scimitar. I’ve fitted roller tipped rockers, which you don’t see that often. Nice aren’t they??

About Sophie Whiptank - aka Bart

I'm just a bloke doing some stuff, the more interesting bits I post on my blog. Scroll down far enough and you'll see me riding from Melbourne Australia to Birmingham, England in 2014. But now I'm working on another project, a single cylinder motorbike engine at 2750cc!
