12. FRAME SHENANIGANS.



The engine could wait for a while i have to check if i can get an engine in. I saw a Dula 2 speed gearbox for sale and rang up SPEEDWAY SERVICES for a bit of advice. "its a modified amc gearbox they used to race big weslake sidecar motorcross using them, pretty indestructable realy" came the reply. That is what i wanted to hear, box bought. 2 speeds is not a disadvantage in flat track racing, at Buxton the shortest track we used last year i used 2nd all day. At all other tracks i shortshifted up into 3rd before turn 1 and it stays there until the flag (or i fall off) so if geared right  2 speed will do nicely . The engine plates arrived from WASP and i went for a trial fit.


she fits with a bit of fettling. By the look of the barrel studs the engine should slope forward. just the way i like it

old suspect cases used as a dummy

clutch actuating arm fouls engine an easy fix

Note Dula gearbox . The bulbous right kickstart casing is gone along with the kickstart and mechanism and a fair bit of exess weight. Gear lever is directly attached to gearchange so its direct no slogger, no slop, just sweet.

With the engine central in the frame the undrilled front mounts could be drilled. 

 

Marked in situ then removed and drilled on milling machine just
 measure gaps and turn up nice alloy spacers to keep motor middle for diddle.
