Today I had a chat with a bloke who knows something about BMs. He suggested I needed to put power on to both the solenoid feed and the main power lead to the starter motor. Do you know what? He was right. The starter motor spun beautifully. I refitted the starter motor and hooked up the cables. I tested it again once fitted. Again it work and this time cranked the engine over (with the spark plugs out). It was fantastic to have the motor spinning under the starter.
I cleaned up the breather hoses and refitted them and finally and hopefully for the last time fitted the air cleaner. I slipped on the engine top cover which means I only have the front cover to fit, once the new alternator is fitted, to have the engine/gearbox complete. It is starting to look like a bike.
This flurry of activity only took an hour so I looked round for a small job. The choke lever assembly caught my eye. I took the assembly to bits making sure that little bits inside did not ping off in the dark recesses of the garage. Off came the cables too. I even took the cables apart. I dunked everything in a bath of WD40 and got the tooth brush busy. Having dried off the bits the worst bits were given the wire brush treatment and back round the WD40 route. The cables were pretty grimy but shooting WD down the sleeve and running the inner cable back and forth and another blast of WD soon had thing clean and running free. Then the tricky bit.... re-assembly. Just to make things interesting everything was covered in grease. Then the cables are fitted to their respective tooth drives. Each tooth drive is located in to its own tunnel. Then it just a matter of lining up the tooth drives equally and fitting the geared lever. Easy? Nope, an extra hand and X-ray vision would have been handy however half and hour later I managed to get everything positioned just long enough to get the circular springs fitted and locked together with the cover and set screw. Then it just has to be fitted to the bike. Guess where it goes? On the left side of the air filter housing. So off came the air filter housing again whilst the choke lever was fitted to it. Putting the housing back on was a bit of a faff. I had to loosen most of the cover bolts again and remove the top cover so that I could get the breather pipe in to position in the left air filter housing. Then put in all back together again...........again.
So here is a picture of where I am up to. Click on it for a big picture.
It is going to be a while before I can afford the major electrical components so I had a think about what to do next. H brought a brew in which was very timely. I few minutes of pondering led me to the carbs. They are bound to be a pain but there are two pairs of carbs in the box. I got them out and tried to figure out which pair was the best. The better looking of the pair had the screw end of the pilot jet snapped off. The other pair where very grimy but at least nothing is broken. I picked the grimy pairs as the ones for the bike and squirted WD40 all over the insides of the carbs and set them to one side. Time to let the WD do its thing. I have to figure out if I know anyone with a parts washer. Predictably, I do but will he be in at the weekend?
