I took the BSA out for a ride yesterday- 70miles over the mountains in sun, mist and heavy rain. Biking in Ireland is always like this- 4 seasons in 2 hours.
I thought that the rain and water would get into the magneto - as there is no weather cover- just a metal cap held by a spring. - but It didn't miss abeat for the whole trip.
All went well for 50 miles, then I heard a knock up front. The knock did not follow the enigne revs- so I was sure it was in the frame or wheel area.
I could not identify the problem on the go, so I continued on until I saw the front fuel tank retaining bolt had fallen out and the fuel tank was hitting the frame.
I stopped - but was in the middle of the countryside -so I got a small branch from a tree and stuffed it between the fuel tank and the frame and continued on-
The bike runs very smooth up to about 55miles and hour and then it's a bit too vibey. But at 55, its plenty quick for the twists of the mountain roads around here- also the road surface is crap - so the plunger at the back is bouncing all over the shop.
So it make for a super ride at lower speeds on real twisty roads- so unlikely for me to die.
After a few more miles the branch got crushed by the vibes and fell out- I brought the bike back home with one hand holding the tank off the frame and the other on the throttle.
When I got off I noticed oil on my hand (the one holding the tank) and all over the oil tank, frame, battery and casings.
Looks like a top end oil leak - so I'll have to look for that too.
Also the bolt through the magneto/dynamo strap had fallen out - probably not tight enough.
So after 2 tanks of fuel (300miles) following the rebuild- the only problems are :-
1. Oil leak on top end
2. Fuel tank bolts and rubbers to be replaced
3. magneto bolt to be replaced
4. still no speedo
Not bad for a 60 year old machine that was off the road for 25years
