CB450 Tracker

Finally got the frame all finished with lugs in place for the seat, tank, inner rear guard, tail light, rear shocks, battery box and rear footrests. I think I'll get it sand blasted rather than rub it all back, but I'll decide on that tomorrow.

I also got out the powdercoater and did the sidestand and the top engine mounts. I also did the original toolbox, as it was in really good shape and will look good on the bike. I'm quite happy with the results.

My brother came over today and started cleaning up the forks, ready for polishing. What a job, they were quite a mess under the paint, full of sanding marks and scratches. He still has a bit more to go but it's starting to look good. While he was doing that I powdercoated the alternator inner and outer covers, after doing a repair to the inner. It had a broken screw hole at the bottom which I welded up and machined first - damn Japanese aluminium, took a while to get it right...
We are doing the sidecovers in satin black, with polished external covers, and the main cases will be flat black, which we think will look good.

That looks sweet, I reckon you could sell a fair bit of this machined stuff if you wanted to. There is a CB450DOHC facebook group that you could join and I dare say a decent number of members would be interested. Fair few of them in OZ too, but mostly US and EU. Even if you kept your's unique and just offered some other custom bits that would be great.
 
Thanks Liam, I'll have a look at that facebook page, although I'm a little busy at the moment, but definitely something to consider.

Well my poor brother spent most of yesterday and today sanding back the forklegs for his bike. It was a hard job, particularly around the brackets, but well worth it in the end. Tomorrow I get the frame back from the paint stripper so I'll give that a coat of paint over the next few days. Very windy here at the moment, so I'll have to wait for a good day.

Finished off the fork legs with new seals, fresh oil and reassembly, one job out of the way...

I finished powder coating the outer engine covers. I still need to tear the inners apart and paint them, but that will be a bit later.

I also made up some new handlebar levers, as I didn't have a matched set previously. I know that they are only a few bucks to buy, but these are matching and made from T5 6061, so they will be plenty strong enough. The next project is painting the frame. I got a quick coat of primer on it when I picked it up from the stripper, but now it needs the full treatment.

Really like the 6061 levers, not only stronger than stock but won't break when bike is dropped plus easy to re-straighten.If cost isn't too high I'll bet there's a market for them with vintage racers (and others?)
 
Thanks guys, much appreciated. Not too sure there'd be a market there considering they took me a day to make each one...

arent many levers designed to break so that the lever is sacraficed instead of damaging the master cylinder? All Brembos i have seen have a small recess to make sure they snap there, unless they are the folding type of course
 
Dead right doc. I usually leave my clamps just a tad loose so that the whole lot moves if it hits the ground, always works for me.

Got the first coats of primer on my frame and swing arm. I just need to rub it back completely and then put some colour on - frame black, swing arm silver.

In between coats I finished off the clutch lever assembly. I powdercoated the housing and made up an adjuster for the clutch cable. I still need to make up an adjuster for the choke cable which I'll do tomorrow.

Couldn't do any painting today as the weather is miserable, so I made a new arm for the choke lever and an adjuster similar to the clutch cable one. The other arm had the cable coming out at a different angle to the clutch cable and didn't look that good. Next time I'll make the clutch lever before the choke lever and get it right the first time....

Thanks guys.
I was watching the Polish round of the Speedway Grand Prix last weekend and that's the adjusters they use - good enough for them, good enough for me.
 
The weather has been miserable here lately, up until today which was quite good. Unfortunately I have to go to Vietnam tomorrow for a month, so the painting will have to wait until I come back. I did, however, get to make up a couple of new inlet manifolds. The ones that came with the kit are OK, but they are universal types and don't fit very well at all, so I milled two flanges that go on the cylinder heads.

I then machined up the two manifolds in my lathe and pressed them into the flanges.

I then welded them on the backside where the taper is.

and then machined them flat.

Once the engine is in the frame I can select a spot to drill and tap a hole in each one so that I can fit up two small spigots to attach the vacuum gauges for synchronising the carbs.
