filled and primed

At long last I am actually doing some real work on my ’68 Puch 250 SGS. I replaced the oil in the tank with some TC-W3, and I think I’ve burnt off¬† all the old 10-w30 that was lingering in the system, much less smoky now.

I’ve fitted the choke plate and it works great, the bike is a 2-3 kick start; replaced the lower bolt on the chain guard (flowed the brazing to remove the old bold, re-brazed a new one on; filled holes and primed the nacelle; repaired a crack in the fender, banged out a few of the dents, and slathered on a liberal coat of Bondo.

removed a rusted/crumpled section out of the headlight edge.

I initially experimented with trying to stick weld the sheet metal, I know it can be done, but it is out of my skill range and I don’t have the time to practice. I did fill one hole on the nacelle¬† but opted to brass braze the others as it is faster and well within my skill range.

It is hard to articulate just how badly dented the front fender is, it resembles a sheet of paper that has been crumpled and smoothed out again, the shape is there more or less, just very lumpy. This can be seen in the picture where I ground off the paint before the resin filler. I’m using a quick-set filler, must say I love it, really speeds up the fill/ sand cycles.

first round of triage

The fender will make a thud sound when finished rather then the nice ringing ding of an all steel fender. I suppose I could buy a less abused fender off ebay, but that wouldn’t be quite right.

Puch parts – and progress

I bit the bullet and ordered a new (low) Magura handle bar, and a complete headlight assembly as my chrome rim is shot and the reflector is completely fried (see photos). Ed (from the forum) and I grouped up on an RBO order to save on shipping.The headlight is euro spec, with a different build and a separate pilot bulb. Luckily I found I have a euro spec bulb, I think it was thrown-in at a swap meet purchase. I love the Puch logo on the lens.

I took the opportunity to dig into cleaning up the handle bar clamp as it is not available from RBO (I didn’t bother to check other vendors). The clamp was so corroded it was like a flaky bar, I took off a lot of material to get it down to where it was reasonable to try and polish, it came up rather ok, the before photo doesn’t show the actual corrosion eating into the alloy. The levers polished up nicely too, the lever and the clamp seem to be different alloys as they patina differently. I’m not going too crazy polishing, just getting them back to shiny so it looks good with those sparkly new bars.
Its nice to actually do some work on the Puch 250, it has been a long time sitting in the garage, waiting patiently.
