Hello all I have just joined 

I have just acquired an Ariel 350 single 1939-45 prefix number RBH which I believe was a Royal Air Force dispatch - Engine crank gearbox needs attention but unfortunately frame and rest has rusted beyond any amount of TLC -  I am presently considering a trials rebuild and looking at using the 350 crank with a 500 barrel - I came across a post on here by a guy called Magnon back in 2009 which read -(see below) -  So what interests me is -  does anyone know who he was referring  to regarding the ally barrel maker he knew off that will suit the std conrod (85mm stroke) and Yamaha xt350 piston (86mm).    THANKS Davedent

 

Hi Bob, happy to provide any info and help I can so just ask.

Tried as best I could keep silhouette like original but did use modern geometry.

You need 350cc Ariel bottom end with std conrod (85mm stroke) and Yamaha xt350 piston (86mm).

I can put you in touch with the ally barrel maker.

Many people have ridden it including Mick Andrews and Sammy Miller it would be fair to say all were very complimentary.

Mick, tested it for Classic Dirtbike Issue Five along with my mates AJS.

Yes it turns tight without tucking or pushing, engines a bit sharp off the bottom, so I'll either drop the compression from 6.2:1 or retard ign again.

It might be easier to PM me.

Hi Guy's.

Hi Dave Mick Dickinson is the  guy that patterned and casts the barrels. 

I have links to him on my website, if you look. just type in the bikes named under my name on the left and you will find it.

 

 Hope this helps,

Regards Charlie.
