Week's Update
Posted: Sat Jan 08, 2011 1:10 am
While waiting for the big parts to arrive from the UK, this week has been mostly one or two hours each evening, and half an hour in the morning, spent getting small things done on the bike:
- Took the passenger footrests to Ricoh, the local powder-coater. They came back looking new with a semi-gloss black finish. Perfect. Took off the rear shock reservoir hanger and the can hanger, to be powder-coated to match. While purists might disagree, by turning the can hanger black, the silencer will look like it's self-supported which, I think, will improve the lines of the bike.
- Note to self, powder-coat the Al. rear sub-frame the same semi-gloss black, after it's fabricated.
- While at Ricoh, noticed some after-market adjustable clutch & brake levers. Choice of silver or black. Silver wasn't finished as well, and the Ricoh guy said the black had a better, harder finish. New levers were way down on the priority list, but seeing as they only had one pair, at just 400 baht each (GBP8ea. compared to GBP25 + del. from HK) I bought them. If, like me, you like to ride with two fingers on the clutch and brake at all times, you need adjustable levers unless your fingers are longer than Edward Sissorhands.
The clutch lever fitted, no problem.
Honda brake levers, it turns out, have two fittings. On the NC30, the adjustable brake lever requires an adapter to maintain it's position within the brake perch. No problem, a couple of washers would do as a temp. solution, and Ricoh supplied an Al. adapter when I picked up the passenger foot rests. The trouble was, there's a discrepancy between the shape of the lever adapter where it should touch, and therefore turn-off, the rear brake light switch. And here we come to a further difference. Most Honda brake perches include some level of adjustment so that the brake light switch had be swivelled forward or back on it's mounting bolt. Not so with the NC30. In this case, the brake lever fitting requires an additional 2.57mm to activate the brake switch reliably. Note to self, how much will it cost to machine a new brake lever fitting, 2.5mm longer? (Thinks, if I go down this route, perhaps it could include a channel for a tiny bearing race...
)

Note to others: DANGER! Be very careful if you fit after-market levers which require an adapter or washers to attain the correct height on the brake pivot screw. The design is not fail-safe. Should your adapter wear with use, it's soft aluminum after all, it is possible the height of the brake lever could fall 1mm+ whereupon it may come into contact with the brake perch itself, rather than push the brake piston in the master cylinder. If this happens, you would have NO FRONT BRAKES. Of course, this sort of thing only happens at those high-G moments when you need the brakes most... Be careful out there.
- Polished the Al. silencer bracket with Wenol while watching TV. Shiny, but not mirror finish. It really needs a coat of lacquer to hold back oxidation. Note to self, find a local polisher.
- Measured the front brake discs; 3.4mm. They are marked 3.5mm min., while the service manual gives a limit of 3.3mm. Emailed UK supplier for discs. Researched braided lines, like the Venhill's rotating bolt design. The caliper piston seals are expensive! Should I wait to disassemble the calipers before ordering new seals? Noted the master cylinder could do with an overhaul (cost c.GBP30).
- Measured the rear brake disc; 4.8mm. Service limit 5mm. A new disc is around GBP120. Found a second hand NC30 rear disc in town for 1500 baht (asking price!) (GBP30). Need to measure it in the shop before purchase. Brakes are next month's job.
- Removed the scruffy old chain-guard for access to the chain slider. Created a new chain slider out of an old bicycle tyre. Cost 0 baht. Time 30 mins.
- Replaced yet more old bolts and nuts with SS fittings.
