Hi Guys. First of all, sorry for the late reply. The bikes oil seal repair had been placed on the back burner for a while due to unforeseen circumstances. I have now fitted them and in the end I rubbed them down to fit, as AWJDThumper suggested. So far so good. Thanks for all your suggestions and help again. Drummie.

Twins / Fork oil seals

Hi all, I've been trying to change the oil seals on my 66 royal star. after getting the oil seal holders off I noticed the new seals are bigger than the old ones. new seal has an external diameter of 46.83mm with the internal diameter being 33.3mm. while the old seal has the same internal diameter the external is 44mm. I have managed to destroy one new seal trying to fit it as its very tight where as the old one can be pushed into place with my fingers. not sure seals can shrink as much as this. Any help in identifying the correct ones would be much appreciated, also tips for fitting them. Thanks Drummie.

Thanks again for all the help. Took the bike to the Glasgow Distinguished Gentleman's Ride Out, and without the lights on it didn't miss a beat, even riding through the monsoon type rain we get here. I've taken it off the road now for the winter, and will be going through everything and changing a few bits ie the rectifier over the coming months. Caulky, I checked the battery a couple of days ago straight after a short run, and it was showing 13.3 volts. I'm going to change it though, and get the new one checked as you suggest. Thanks again.

Thanks Guys. I believe the battery has had it. I was out on the bike yesterday and after around 20 minutes stopped, and still with the engine running switched the lights on. The bike cut out after about 10 seconds, which is a lot worse than before. Switched them off and she started first kick and rode perfectly. I will have a look at the switches and wiring and also the headlight bulb. That rang a bell, as I remember that being a fault on a Honda 400 four I had a few years ago. I was thinking of a possible conversion with a boyer bransden powerbox if need be. Do any of you know of them or better still used/use one. Thanks again Drummie.

Hi again, I've done another voltage check at the the battery and at idle with lights off i'm getting around 14.3v this increases to 16.2v at 3000 rpm.
With the lights on i'm getting 11.2v at idle increasing to 14.5v at 3000rpm. Also Its fitted with a boyer mirco III ignition, if this makes a difference. How do these readings seem to you all. I've also cleaned all the earth points.

Hi Eddie Simpson, I have done some tests this morning and first of all found that my first multi-meter was faulty (now changed). When the bike is running at idle it reads 0 on the ammeter. when revved up it increases to just above 0. with the lights on, it drops just below 0 and back to around 0 when revved (headlight gets brighter when revved up).

With the engine switched off I got a reading of 12.25 volts across the battery terminals. when I switched the lights on for around 20 secs the voltage dropped to around 11.25 volts. When I started and ran the engine for a couple of mins then switch it off, it jumps up to around 12.80v.

I also found that when running i'm getting 14.30v at idle which increases to 16v at 3000 rpm, when connected across the battery terminals.

I was thinking rectifier, but then thought it would of blown the bulbs by now.

Thanks for all your help. I'll have look at it over the weekend. That book does look like a worthwhile buy.

I have checked this morning and the headlight does get brighter when I increase the revs, not to the point bulbs will blow but definitely an increase.
Also noticed a fuse on the lead/wire to the negative terminal on the battery. with the engine off and battery connected i'm getting 12volts from it, but 0volts from positive side. sorry if this is obvious but electrics are not my strong point.

Its a 1966 a50.

Like you said Star Twin I don't think its just the battery, I'm not that lucky.

I've not noticed JulianS, but will check that tomorrow and let you know.

om15 the battery will need replacing. Put it on charge tonight and read fully charged after around an hour. So something definitely wrong there.

Any idea why I cant get a reading from the multi meter. as it fluctuates wildly.

Hi all,

Out on my bike today for a run.  Decided to use the lights.  Haven't needed to use them yet, so today was the first time.  Rode with them on for around 20 minutes.  Stopped bike and switched it off.  Went to start it again after 5 minutes and it wouldn't start.  Checked the lights and they were almost non existent (a slight glow).   Jumped it with another battery it fired up straightaway and the lights were fine.  Connected multi meter to it while it was running but readings were jumping all over the place so couldn't get any kind of reading from it.

I got the same problem using the multi meter when I got the bike a few months ago.  I've done decent trips on it and it has always been fine until today when I used the lights for the first time.
I've had charging problems with other bikes before but always got a reading to show its not charging
Any idea what the problem could be?

Thanks in advance.  Any help much appreciated.

Just a little update. I finally got myself a BSA. It's a 1966 A50 Royal Star. I must be a bit of a poser, as i'm loving the attention it gets when i'm out on it haha. Thanks for the help and advice given earlier in my search, it was much appreciated. I will no doubt be online with a few questions very soon. Drummie.
