I enjoy riding the BSA and it has made many trips around my area since I purchased it in 2009. It has run with minimal issues, and aside from routine maintenance, has not required much attention. This changed last summer when it started acting up leaving a few things in need of repair this winter. There have also been a few enhancements I have wanted to make for a while. Here we go......
The clutch plates were at their lower wear limits which I discovered last summer. New EMGO cork plates have been installed to replace the Barnett plates which hook up good but do not let go after the bike has been sitting for a day or two. Breaking them loose is a pain. Using EMGO plates was a Hornet modification and a tip from an old BSA dealer in Hobart Indiana. To keep the primary from weeping oil I went back to 30W. I know I will never get it leak free but I will make it "leak freer". There was no final drive chain oilier hole to be found in the Lightning primary which I thought may also have been causing leakage.
Darn....forgot to loosen the counter-shaft and primary nuts before taking the rear wheel off. Lesson learned again. Reassemble to disassemble ........
An easy way to pull the clutch plates.....a mechanics magnet.
I have had a mystery knock coming from my primary for a long time and I finally found it. The center in the rotor was loose. This was discovered when I tightened down the primary crankshaft sprocket. The center will not move when on the bench but does so on the bike. Luckily I had an extra one on the shelf I could use. It is installed and tightened down with no issue detected. I will need to reset the timing since I do not know how the last rotor was lined up when it was set.
My "Mystery Knock"....the offender....a loose rotor center.
The next fix was to repair the cracks that have been working their way back on my headlight and up the rear fender. After dis-assembling the fender I found a much larger crack that was almost across its entire width. It was not very easy to see so I welded and painted it.
My vintage plate also suffering a terrible fate.
The steering head has had a hitch in it for a while. When I blocked the front wheel off the ground and removed the steering damper it was plain to see that the bearings and cups were damaged. The SRM roller bearing upgrade on my Hornet is silky smooth and I decided to go the same route with the Lightning. This was a pretty uneventful upgrade, just a lot of stuff to take off and reassemble. One area that needed adjusting was the stack up of the bearings as the steering lock rubbed lightly when assembled with the roller bearings.
The SRM Kit ready to go.
Out with the old......hard grease, damaged bearings & cups.
Nothing to do with this post but just plain cool! The original decal - Parson's Auto & Cycle Supply.
While I am eager to get the BSA back on the road and try my improvements it is 20 deg f outside and it will have to wait. Time to finish the wiring upgrades I started before Christmas.
Not very good bike riding weather here....nice for taking photos.
