Typical bank holiday weekend

Did manage to get out to the Forest Trophy Trial on Sunday, but the rest of the weekend was bit of write off on the outdoor front. Therefore spent some shed time working on putting the Cota together.

I’ve failed once again to get the engine running correctly on the SWM TLNW project, so decided to switch to the Montesa.

The frame had come back from Redditch Shotblasting who did an excellent job on a fairly corroded frame. Silver is the colour for 1972 bikes, which the frame number indicate [[The dating letter also came through from Roy Bacon to confirm the year]]
So spent some time working on the bike, whilst listening to PlanetRock and the cricket from Manchester, where it wasn’t raining.

-14h00 after ferrying of kids and others around got to the shed around 2 o’clock. Saffron came down also, with overalls, to help. Started by assembling all the bits in the workshop and put the frame on the stand. Checked the engine oil and cleaned it up a bit. The head and barrel really needs blasting and spraying so will get that done at somepoint.
– 15h00 Saffron’s up for some spraying, so painted the exhaust front pipe, the rear brake pedal, as well as the side stand and footpegs. Put the steering head bearings back in the frame. Plenty of grease to hold the ball bearings in place (wonder if there is a taper rolling bearing set for the bike) and put the yokes together. The pressed top yoke looks rather friable.
– 16h30 Front forks into place, which are not exactly massive either, reminds me of the Honda TL125 front end. Not really expecting too much from this bike. It does look rather small.
– 17h30 Need to get back in the van to pick up Tamara, but manage to clean up the ignition coil and connect it in place. No spark, no surprise there so need to spend some time with that later.
– 19h00 Need to prep the Beta ready for tomorrow’s trial, so leave the Cota till tomorrow. Looking good though

Forest Trophy Trial

– 08h30: Its pissing down and blowing a gale, so off down to the shed and start work on the bike. Gavin pays a visit and notices straight away that I’d put the head on back-to-front (I would have noticed when it came to put the exhaust on). No spark from the electrics, so check the earthing and get the meter out of the tool chest.
– 11h30: back from a conference call and a shopping trip. Further debuging of the electrics including trying a couple of alternative coils / plugs etc. Check the connecters and think about removing the flywheel nut; doesn’t want to come off.
– 13h30: back from lunch and continued to look at the electrics. Heated the flywheel nut, but still not keen on coming off, so need to think on another plan. The contact gap was completely out. The listings on Montesaweb indicate a 0.40mm points gap, so set and adjusted them. Also cleaned the faces. The meter shows around 2.5v peaks from the plug gap, but need a little more than that.
– 14h30: still no joy with the flywheel nut; going to need another pair of hands, or an airgun (or both). Decided to fit the exhaust, which is of an interesting design (?) and with a pea-shooter exit pipe. Maybe not getting enough oomph from flywheel, so hence the need to extract it.
– 15h45: England have won the 2nd test at Old Trafford, after a large 1st innings deficit. Still no joy with the electrics, but the rest of the bike is together and now looking the part. Just need to make it run. The stand is a little short (designed for the original 20/17″ wheels) but works. The clutch cable was ok and runs underneath the engine, though is not a one figure pull. Cup of tea and think further about the electrics.
– 18h30 Ended up making dinner. Back to shed, thinking perhaps is an anti-clockwise thread on the flywheel bolt. The bolt itself is only half-way on which seems a little weird. Yep, quick Google [Good reason to have Internet access in your shed]] and it is [clockwise to loosen . Could be a problem with the condensor, handily placed (like SWMs, behind the flywheel).
– 19h08 Flywheel nut off. Now for the flywheel. Not sure about pulling it with a leg-puller, so need to see if I can find right puller (male, right hand thread, 27mm)
