Heavy Twins

Hi
Would someone be able to give me the correct length of the top distance tube for a bolt up rear subframe its the top tube which is often used for a tank strap buckle. Its a 1954 wideline featherbed frame.
thanks

Hello. Just to set the scene I inherited a 1963 88 sport with a 1966 650ss engine. Well a 650ss crank and head with a 99 barrel anyway.

Looking for information on a 1961 88SS.

Hi All,
I'm a new owner of a lovely 1966 Atlas (got it Fri) which I love more every time I go out on it but it has come to my attention that the front tyre is definitely in need of replacing.

Me again! 

Hi all, I have a Thorspark ignition on my 64 Atlas which I am trying to get going. Everywhere I look a get the timing for fully advanced at 28 to 30 degrees. However, this is if it's running at revs - ie. when the ignition advances. 

Can anyone help?

I think my coil went pop earlier as it came lose and probably shorted out on the frame. Ordered a new battery too as its dead. 
Back to the coils, I use a Boyer  power box 12v system. So how do I know if the coils are non ballast? 

I have just returned from another bedding in run with my recently resurrected 650ss bitsa. I was making progress in top gear on a nice straight road when I noticed extra slack in the clutch cable.
