Default Re: what did you do to your motor bike today?

I do all my own bike work. I get parts cheap too, from -- Bicycles, Bike parts, Mountain Bikes, BMX, Road Bikes, Haro Bikes, KHS Bikes, Felt Bikes at Niagara Cycle Works, nashbar, and sometimes a few others like e bikestop.

I don't understand why people (usually pedal bicyclist) want to shift under power. This causes so much more cassette and chain wear. Easing up just a little bit on the pedals (or the gas in your case) will let the chain just fall swiftly into the next gear without the hard CLUNK or worn or broken teeth.

Steel cassette gears will do much better, and a chain checker or metal ruler are essentials for keeping your drivetrain in check. Steel freewheels are still a good deal for heavy use, and can be had in the 34,28-13 varieties called "MegaRange".

Well, my motorized bicycle is fully assembled and ready for tommorow's commute. New exhaist gaskets were doubled where the OEM muffler bolts onto the expansion pipe's silencer. Both of the pipe's slip joints were treated with liquid muffler weld. Then they were wrapped in a saturated exhaust bandage. This should cure the exhaust leak I've been having.

While the engine was out, I opened the pocket bike gear box to check for damage. I had been hearing a noisy bearing, so now was a good time to check. All gears and bearings were still greased. The gearbox has grease not oil, which leaks out and makes a mess. The last time I worked on the box, I cleaned the mating surfaces, but did not replace the torn gasket or use sealer. This time, I cleaned and sealed the box well.

I have a spare gearbox handy, so I'll pull one of its bearings and find good quality replacement ones.

The exhaust fix should cure by 7am tomorrow, when I leave for work.

Got my CNSv2/GenB carb working by using a Manic Mechanic intake.

As well, I adjusted the float tang, put my drilled out NT air filter cover on, tightened the jets, and chopped the choke cable.
