First cylinderhead on the tractor pretightened and the second also now getting mounted.



Adapters home! Looking good so far! :D

One pair of newly restored Zenith 40 TIN's. Now off to next parts...

Working on the diningtable with the timing chain housings... :) The factory sealants are partly off on the backside. Will be resealed with JB-Weld sponsored by www.anorrback.fi


The timingchain guide mounts cleaned from old sealant.


JB-Weld sealant applied.



Started cleaning and polishing the first of the six cylinderheads now too.

Exploded view of the second Zenith.. :)


The Zeniths compared to the Triumph trottle bodies. Same sizes on the butterflies.


Played around with CAD and designed these adapters. Now ordered and hopefully will arrive in a couple of weeks.


Finally got the exploded tractor wheel replaced with a better used one. Have to wrestle it back on the axle tomorrow... :)

The Triumph ITB's arrived from UK today!

This pair of Triumph ITB's will arrive during next week. Will be adapted to the Doppel engine during the winter.

Scored two sets of these Triumph Sprint ST 955i throttle bodies from UK.
