PUCH 250 SGS

Restoring a barn-fresh 1966 Sears Allstate

New tires – old Puch

Original Semperit tire.

Original Semperit tire.

The original equipment Semperit tires on the ’66 Puch 250 SGS are getting a wee bit, well, tired. With my current push to get the old girl road legal I’ve ordered tires and checked the brake pads. Really, it’s time I showed the bike some love, especially after several years of being ridden hard and put away wet at Paris, literally.

I’ve ordered a pair of Duro HF319 from a local dealer, the tread pattern looks pretty vintage so they should look right.

DURO_HF-319

Part number : 113113

  • Designed as a general replacement tire
  • Excellent load carrying capabilities
  • Can be used as a front and rear tire
  • Excellent puncture resistance

I mean really, isn’t that the basic description of a tire?!

I will also look into getting a 16″ rim for the Velorex to lower the hack as it is currently wearing a 19″ – then perhaps I’ll need another Duro.

I came upon this page from a Sears catalogue a while back, it is a great illustration of the Puch badged as a Sears Allstate, although I think the illustrator didn’t understand how brake and clutch levers worked. I’m pretty intrigued by the brown sack outfit the guy on the left is wearing. Is that rain gear?

Amal tips

Amal - high speed modI had my Amal concentric carbs sleeved by Bruce Chessel of Woodstock ON – it was the best thing I’ve done for the bike. Sleeving the carb is actually a bit of a misnomer as it is the slide that gets sleeved, the body is just bored out and the slide is sleeved in brass to prevent galling from like metals.

I stumbled upon this service bulletin in a forum the other day and thought it worthy of reposting. My 750 commando is so thirsty at WOT that i need to open both fuel taps to keep the engine from stumbling – perhaps this will give a bit more top end?

Here’s a note from Dave Comeau (Atlantic Green Technical Services) when I was running 32mm carbs before I got the original 30mm Amals re-sleeved:

The ’70 model you show on your website, assuming it is the one with carb problem would not have originally been a 32mm. However that is not a big deal that they are not 30mm.
Your symptom of rough running at just off idle/light cruise is indeed….. cutaway.
Raising the needle will have more affect at bigger throttle settings.
If you have combat carbs with 3 cutaway, you will do better if you mod them to 3-1/2 or try them at 3-1/4 before you go all the way to the full 1/2.
IIRC each cutaway # is 1/16″ ,,,,,so a 3 cutaway is 3/16″
1/2 is 1/32″ custom 1/4 is 1/64″

’74 850 Commando – start at the fenders.

I’m getting the ’74 850 Norton Commando ready for sale in the spring. Phase one is to dig out the parts and see what’s missing, what needs help and generally what’s what. I’ve never had the bike running as I bought it in mid tear-down and just dragged it all home and put a tarp over it.

Today I got out the fenders and realized they are dirty (paint overspray), dented and looking pretty sad. I decided to do a quick fix on the front fender dents from a bottoming out – the bike came with two front fenders and I think this was the spare. I was in a rush (not much time theses days…) and the final product isn’t perfect but good enough – I forgot how picky stainless is to polish – very similar process needed as with Platinum.

The bike has chromed covers – not my cup of tea but it’s not looking so bad cleaned up.  I see one reason the bike was apart, looks like the oil tank was brazed, needs a lick of paint.

SIP in Southern Germany

A couple of years ago I was on my honeymoon, we stayed in Southern Germany visiting family. I knew I was just minutes away from Germany’s (and worlds) largest suppliers of Vespa parts – SIP. Scooter Innovation Parts (SIP) have an impressive array of parts for classic scoots such as Vespa and Lambretta as well as modern buzz boxes like Aprilla, Benelli Kymco etc. SIP develop a lot of custom performance parts as well as bolt on goodies.

They started in 1989 and have grown to 50 employees shipping over 400 packages a day! Wow! I am jealous of their success. I spent the summer of ’89 working close by in Bavaria,  buzzing around on an ancient small frame loaned to me by my cousins, so I have a soft spot for Germans on Vespas.

Here are a few pictures of SIP facility on Graf Zeppelin Str. in Landsberg, gotta love the street name. They have a small showroom with a selection of great classic scooters.

Choke on this

In response to Ed’s implied question, and I paraphrase here, “What the hell have I been doing?”
I could drag out the usual answer of too many irons in too many fires, but this time I’m being vaguely logical about my target of being up and running for mid June. I asked myself “what need be done to ride?” The obvious answer of a choke sprang to mind. I did start and run the bike, but last time I tried it wanted to be choked… so off to the local Goodwill and $2.02 later I have a dog biscuit tin, soon to be a choke.
Here’s my progress so far….
