Looking good but I would hate to get some patina (dirt) on that engine !!!!

Hi Laurie,
Looks very nice job, but I wondered if the dynamo chain might be too tight (looks tight in photo). Best to have some slack in it as there is often some eccentricity in the sprockets which puts a load on the dynamo bearing. Just a suggestion, may be OK as is, but thought I would mention it.

Normal for approx 1/8" slack on the Dynamo chain at mid point. I would also recommend a split link as trying to take the chain of in situ is difficult

thanks for all your comments
the dynamo chain was set with about 1/4" play at its tightest run so hopefully should be ok but must admit looks taunt in photos,there was 3 broken fins on the head but i had some new ones fabricated & welded back on
all the best laurie

hi everyone just started the gearbox now ,straight away  noticed a stud sheared off on the shell then opened it up & it was packed full of old grease ? which i dont think sounds right i thought there should  just be gear oil in there but none at all perhaps someone has had some experiance of working on the gearbox & could enlighten me.nice messy degreasing job for me now
regards laurie

yeah should be gear oil, I just throw some motor oil in mine :o No combustion ,so mine always stays golden in colour, have to top up now and then if i lean bike on a wall to the left, trickles out kick start shaft.I didnt worry about any felt inside to stop that,none comes out when riding .
