... still trying hard. But the net can be distracting ...

It's radial play at the pinion tip. Not to be confused with a loose enddrive housing. Depending on the state of the outer needle bearing (the rusty one) sometimes the complete enddrive dangles to and fro. Hubert

That's been the fun part so far. Now check pos. 22 and 14. These bearings, mostly 22, are the only things that tend to fail inside there, on some bikes at least. If you decide to look after them they might keep you busy 'till spring. Hubert

In another context I read about a speed record established with such an engine: average speed over 250 km/h. That's somewhat funny if you see a frame typical for that era as on the pic above. Hubert

Two cylinders, 4-stroke, 150cc? 1-cylinder double port, 125cc? A crude mixture of several styles. The frame looks German, mid-sixties, the engine Italian, same time, also the lights. I'm not sure about the insurance plates, I've seen them in Italy, but the only thing I know for sure is that we don't have them in Germany. The 'crude mixture' probably comes from the bars (which aren't apehangers in my opinion, more sort of what could be found on 70ies High-Riser bicycles) in combination with the colour. Hubert

You can search near the oil cooler also. Some had it there. If your bike really has come without one it doesn't mean anything is damaged or worn. First it's an unlacquered plastic tank, second you don't fuel up out of canisters, third several filters are built in anyway. One in the petcock, one in the pump, one in each injector. You cannot run dry the tank, so fourth there's always some sump left where debris could settle. Hubert

You tried the 'whack in a torx socket' trick? Hubert

The nice thing with searching the net (or with this Quiz) is what you find and haven't been looking for. I could not find something for the above so far, instead I came over this: http://www.carandclassic.co.uk/car/C457242 You know, it would be mine right tomorrow, alas it's England based Hubert

I would suggest a big hammer instead of heat. If you talk of heat you should think of an acetylene burner, a big one even. Anything else is useless. Take a big hammer in such a case, and a solid iron, and then bounce the head of the bolt with one good punch. You'll be able to tell a good punch, you'll have felt the bolt coming so to say. Use the best quality tools only. A socket that breaks because it's too hard will do damage to you and the part you're working on. Never a length extension on a ratchet. Hubert

Finding the name wouldn't be too difficult. But then, was it someone like Phil Read or Heiner Fleischmann? Anyway, after what I found it's not a real restauration as such, it seems to be rather a 'very way back retro' project. Hubert

Here you go (a little bit bigger at least): http://raresportbikesforsale.com/wp-content/uploads/2010/01/puch-racer.jpg

Gilera? Garelli. He started with double piston 2-strokers. The same basic concept as TWN (in my special case). I read a story about the pre-war DKW racing bikes with similar pipes. Either you outpaced them (hardly) or you kept a good distance. Otherwise you've been deafened for the rest of the day. BTW, you know this: Quiz - Burnistoun ('Music, that's my thing') Hubert

I also heard the "GT" might make a difference.

One Friday afternoon I went to pick up my car after one week of repair time in an official brand shop. When I came there and saw the owner hanging out of the hood and his young assistant sitting inside, stirring the gear shift lever, it was clear that something has gone wrong. He said he forgot to put in some part and now was trying to get it in from the outside, something like that. Well, shit happens I thought and watched him trying for some minutes, his buddy tediously stirring the stick, until he started moaning about endless telephone calls and this and that and finally he said: "Look, a gearbox is a difficult peace of work". Being somewhat stunned by the whole situation I replied "Yes, for a butcher that might well be so". I had my son with me, 4 at that time, means 20 years ago, he still vividly remembers what came next. You just shouldn't say that to an overweight, choleric mechanic, trapped in a somewhat unfriendly position headfirst in a car he hates and his nerves laying blank since 2 or 3 hours maybe. And that was no EFI car and no self-made mechanic. Anyway, it's probably true that most Guzzis get raped by the owner sooner or later, something not so typical for other brands you might think. Hubert

Bullshit. The great thing about the 'Good Old Days' is the fact that we were young then, each in his own time. You didn't think about tomorrow, you just were tomorrow. So why bother about future things to come? They'd come this way or another, quite the same way as yesterdays' things did vanish. Maybe sticking to old technologies is an attempt to get hold of one's own vanishing existence? Hubert

Ebay. 70,- Euros, it was a lucky day

They wouldn't dare this in Germany, at least it would surprise me. I'm quite sure this would remarkably affect their sale numbers. Actually I have the AVON Storm 3D X-M on my bike. 180 on a 5,5 rim. After years of 160s I can't say I would have noticed any negative effect on rideability, be it agility or high speed stability. The last set were Conti Road Attack II. Good tyres, as most others probably, but sadly dissapointing in rain and in terms of durability. The Avons I couldn't really challenge last season, the last three weeks being cold and wet on dirty roads, but so far they feel promising. Hubert

The badge looked like that, but googling 'Horex V-Engine' is not that easy actually. Haven't tried V-Twin, though Hubert Edit: Did it now, found this: http://www.diagnosis2012.co.uk/vtwinnews.html

Do you have a source for linear aftermarket springs that would match the Marzocchi legs? Hubert

Well then, why not. Maybe 'Don't use' was a bit harsh. It may come from the times when 'Battery Joggers' were on the market. These thingies cycled the batteries and told people that would be a good idea. Anyway, as long as your bike doesn't suffer any parasitic drains like from watches or aftermarket regulators a well charged Oyssey doesn't really notice half a year on the shelf. Hubert

End of October I stow away the bike, March I pull it out again and press the button. That's it. It works for me and it works for the buddies I have over here. It does not work for the 6V types I have in my 50ies TWNs. They need charging every 6 weeks or so, depending on how cold it gets. As we actually have the Florida climate here, the mentioned 6 weeks already give a measurable loss of charge. Hubert

Where did he get the tyres? They're the dot on the i ..

The V11 makes life easy for them. Normally. It starts easily and the reg. voltage stays below 14V (as long as you don't mess it up). Add to this the robust nature of this type of battery and the fact that a M/C battery normally is not cycled, and 6 years lifetime are the least you can expect of them. My first battery I ruined with a defect starter (mags came off) at the age of 7 or 8. The second one I nearly shot with a defect regulator which went up to 17V at least. I noticed this only after the second bulb went off after just 1 week or so. It was a good one, Nightbreaker or the like, and it really was worth the money - I thought Anyway, the Odyssey litterally pissed itself during these approx. two weeks, nonetheless it's also in its 6/7th year now. Don't use a tender! Hubert
