Does anyone have the specifications for the oil inlet valve spring for early 2 3/4 engines - Part number 424.   I have tried to order one from the club spares but apparently Jeff Swan is indisposed at the moment.

Have you tried the new Drafts feature yet? I just lost a long message today and learned my lesson. It is a good idea to save a draft of any long post you are writing. You can then just keep writing and keep saving a draft, knowing you have a backup if there is a glitch. The draft is automatically deleted when you post the message.

My B29 does not have anything covering the clutch sprocket and chain area as shown in the picture, should there be some sort of guard there?

Type B29 into the members forum search engine....clearly shown in the pics

I did not see it in any photo.  Maybe I was not clear, I do have a chain guard (picture attached) but was wondering if there was any part that wrapped around the clutch sprocket in front as shown in the photo in my first message.

There is a holder srewed on the engine for fixing the front of the chainguard to the engine.
Do you have this?

I will try to find / make a photo for you.

Do you have this part for your B29?

Hi Mark

My 29 600 has the remnants of a front sprocket cover and I have a copy of the factory drawing for a 600cc cover it might be similar to a B29.

too many dougli not enough time!

I have a 1930 H3, nearly similar to the B29, but a heavier flywheel on the engine (ER type engine instead of EN).
On my bike is no front part fitted to the primary drive.
I have thought it is original, but may be, it is missing?

Michael, I do have the bracket you took a photo of, and I currently have the main chain guard fitted.  It just seemed odd that the clutch sprocket area did not have anything covering it on my bike.  The leading edge of the primary chain being exposed to the elements just does not seem right to me.  Daren, that drawing looks like what I was hoping to find, now whether or not that is appropriate for the B29 remains to be seen. 

I really appreciate all the help with this!

Daren, I checked the dimensions on the drawing and the clearance on my bike, and it would not fit.  However I went ahead and made something similar and it works nicely.  The engine and front of the bike stays cleaner, and I believe the chain will stay cleaner too.  It's hard to take a picture of it, but attached is a photo of the guard in place.

Thanks all for the help.
