I have a feeling that this may turn into a long thread since I'll add to it constantly so I'll just provide some very quick background info. You can skip this paragraph below if you want to go straight to the to-do list.
I have been working on a 1984 Honda CM450E since last year June. I am 20 years old and it is my first-ever motorcycle. I am studying automotive engineering and I enjoyed working on my friend's project cars so I bought this project so I can finally learn to wrench on things myself. When I bought the motorcycle, it had 60,000 km on it, and I don't know much about the history of it, but I am assuming it sat for 20 years as I have found that the last time the bike was insured was in the early 2000s. Before I bought it, the bike was running, idling well, and started on the first crank, and all these things I mentioned, it still does today. I live in Ontario, Canada, where insurance is mandatory, and for motorcycles, I must pay for the whole year for insurance. I have a car so this bike is in no way my only form of transportation, so it being out of service for a week or two isn't that big of a deal to me, however, I want to make sure I won't have any hiccups or problems that could potentially cause my bike to be out month(s). This will be mostly just a weekend bike to enjoy the twisties, maybe some longer distances drive, and going to work here and there.
Now, I have come here to ask, do you guys think I have missed any critical steps, or should add things to the list to ensure that this bike will be reliable and not get me stranded?
Note: I have replaced every part that I needed to replace with OEM spec replacement parts or aftermarket parts that are as close to stock as possible. I did not change the jetting on the carbs and cleaned and reused the old ones following LDRs guide. The only thing I plan on changing from stock on this bike are the handlebars so I will change the cables as well.
So far, I have done the following
- Replaced tires
- Replaced both front and rear drum brakes (servicing the drums themselves as well)
- Replaced both sprockets + chain
- Changed Oil and Oil filter (no sparkles in oil)
- Changed Fuel filter (will change again due to being the incorrect one)
- Changed Air filter
- Rebuilt carbs (following LDRs guide)
- Adjusted valves
- Adjusted cam chain tension
What I have left to do (not in order)
- Compression test (I know, I should've done this first)
- Sparkplugs (replacing it while compression testing)
- Clean rust in the fuel tank
- Maybe a leakdown test?
What I haven't serviced yet, however not sure if I need to
- Fork seals (I remember checking when I first bought the bike and rubbed my finger across it and didn't notice any grime/oil, haven't checked properly since then)
- Wheel bearings (haven't fully tested to see if there are any issues with it, however did not run into any handling issues or characteristics and I have gotten the bike up to 100km/h, in a closed area of course).
- Clutch (no signs of a slipping clutch)
- Balancer chain tension (manual says to adjust every 19,000 km, wanted to get your guys' thoughts on this process on how this process is - looks a little intimidating, but will still do it).
I don't think I am forgetting any important info, but if I am, I will update this.
Thank you everyone for the support and the constant help over the last few months, would not have made it to this point if it wasn't for this community.
