Hagon Jap Speedway 1972 frame

How do I prime the oil pump? I've put oil into the frame, pumped oil into the oil line going to the pump and have been turning the rear wheel until I was ready to drop. I had bubbles every, maybe 4th turn of the wheel. I haven't seen a drop of oil in the oil discharge box. Should I see oil in the discharge box? My oil adjusters have been in and out so I can see the pump is pumping, but I haven't had any oil being pumped out. The back adjuster is for the crankcase,right and the front adjuster is for the top end Right? Or am I just an idiot. Any help would be ever so helpful. If you can help a brother out, I would be ever so grateful. Thanks my motorcycle brothers.

SPEEDWAY RACER
We have just come into possession of an old speedway racing bike and have some questions that we hope you can assist us with. Details of the bike that we have been able to establish so far are as follows:

FRAME: Hagon - No. 01-539-8416
GEAR BOX: BSA - No. 65-3364
FUEL TANK: JAWA
ENGINE: ??? - No. MSS-8280

From this info, could you please advise the engine capacity and year of manufacture and confirm that the "MSS" refers to Matchless??

Many thanks

I think the engine is a much-modified JAP Twin Port from the 1930s. Ed.

There was a desmo conversion around in the 60's and it would not surprise me if that is one. Maybe?

It doesn't look like a Desmo. But if you look at the timing cover you will see why its a Velo. The latter link is all about Desmo's of all persuasions.

Many thanks for your fast response.

However, are you absolutely certain that this is a Velocette (modified, of course!!) with an engine number of MSS-8280? If so, could you let us know your opinion as to the year of manufacture and engine capacity (in its original state)?

The reason we ask is that, at this point in time, we are hoping to sell the bike.

Kind regards
Linley Green

Quoting from http://www.croesus-consultants.co.uk/v-tec/ :
"Velocette built engines and frames separately, kept them in the stores and eventually built them into a machine. Therefore there is no direct or logical relationship between engine and frame numbers. It is not unusual for an engine to have a much later frame than the next engine in the numeric sequence or vice versa. This causes problems particularly towards the end of the year where the last frame number I can find does not necessarily belonging to the last engine number of that year. "

Therefore it is not possible to accurately date your engine. Carl seems very confident that it's a Velo, and I would trust his opinion. But absolutely certain? No.

thank you for your reply.I have the bike at my friends house as we were going to rebuild and restore the bike however other commitments have forced my hand to probably sell the bike .I will get some photos of the bike and download them for you as soon as I can.The engine is a 500cc and was tricked up and rebuilt in 1980 and never hit the track as I had a very big get together with the safety fence on my spare bike and never fully recovered to ride this girl.Will get back to you shortly.
-Regards Paul.
