| Hey Cibby,
I've only just finished running mine in - so haven't had a look at the head yet.
I'm off to India for a week on a business trip - but guess what I'll be doing when I get Back?
Things may no be what they seem however. I remember when buying the new Hummer, that one of the e-bay feedbacks said the bike wasn't a true OHC - but then the comment had been withdrawn by mutual agreement.
Also, the guys in the Phillipines (who do the hot version of the Zongshen OHC engine), mentioned push rods in their improved components list. I thought it was an oversight at the time and that some text had been mistakenly carried accross from ad they do for the hot pushrod engine. Now however, your observations would cause me think again.
At the end of the day though, Dreamrider didn't say the engine had no pushrods - just that it had an overhead cam. You may find that the operating cam is indeed located overhead - but operates pushrods using some weird ass transfer mechanism.
Anyway, let me know what Dreamrider says on the matter. If there's no clear answer by the time I get back - I'll take mine apart and figure out what's going on.  |
