I started properly learning about mechanics with motorbikes as at the time it was a cheaper mode of transport
2023 Honda CB125F
The Honda Cb125f was my first bike, and it taught me a lot about mechanics through my ownership and after I sold it to my friend.
Services:
Oil, air filter, and spark plug chnage.
Did weekly checks to ensure the chain was at the correct tension and the drive chain was lubricated.
Brakes:
Replaced the broken brake hose with a steel braided line.
Changed front pads.
Bleed the front and rear brakes, as it used a linked braking system.
Electrical:
Crimped and made a charger so that I can charge my phone on longer trips. The standard Oxford charger said the parasitic draw wasn't enough to drain the battery, but I found it drained it a lot, so I added a switch under the seat to turn it on and off as I liked.
Drive chain:
Chain and sprocket: I also replaced the cush drive rubbers, as they were a bit worn.
Body Work:
After I sold my bike to my friend, he unfortunately low-sided the bike, and a lot of the bike's plastic fairing was broken, and the front headlight plastics were snapped. I spent my time checking over the bike for anything bent or damaged.
I replaced the footrest bar and footrests because they were bent.
Plastic fairings were changed.
front cowl was changed.
Left side indicators were changed.
Replaced the kickstand switch because the internal metal switch was sending an implausible signal.
2007 Kawasaki Eliminator 125
This was my brother's first bike; unfortunately, it broke down during a day out. Although they're not in any particular order, below are images of the work I did on the bike.
Engine:
I swapped the engine with a replacement.
This was a big task for me, as I diagnosed that the engine had lost compression with a wet compression test, which most likely meant an issue with the rings and explained the smoke coming out of his exhaust!
Removed the old engine stator because the new engine's wiring was cut.
Added new starter motor wire.
Cleaned and painted the old engine mounts, and secured them with red Loctite and torqued them correctly.
Tested new engine compression.
Brakes:
Replaced and bled front callipers and pads.
Replaced and adjusted the rear drum brakes.
Drive chain:
Chain and sprockets were replaced.
Used a Dremel to sand down the sprocket retainer, as it wasn't machined correctly.
Electrical:
Also added a charger to the bike
Crimped a new indicator into the existing wiring.
Battery replaced.
Fixed the horn by cleaning its contacts.
Replaced the side stand switch so the ignition cuts off when the bike is put into gear.
Carburettor and fuel tank:
Stripped and cleaned the carburettor; also installed new fuel lines, as the old ones had degraded.
Replaced the fuel tap gasket.
Bodywork and miscellaneous:
Fixed the fairing with putty, as it is no longer being reproduced.
Replaced the mirrors as they would swivel on the mount.
Replaced the old speedo cable, which had snapped.
2006 Suzuki SV650
My first bike, which I have owned for about a year
Services:
Oil, air filter, and spark plug chnage.
Valve clearance check, but it was within range, so it does not need to be adjusted
Brakes:
Rear pad change
Rear brakes have been bled
Electrical:
Installed a Healtech thunderbox and charger on the bike so the charger switches on once it detects around 14 volts.
Crimped a new indicator as the old one was drooping
Miscellaneous:
Installed an A2 restrictor kit on the bike, as I am only licensed to ride A2-compliant motorbikes.
