PostSubject: Mechanical Atlas misadventures   Thu Mar 03, 2011 10:55 pm

Hi guys. After having several Atlas engines apart these last few months I've come across a couple of consistent problems. I guess the first place to start would be clutch baskets. The OR and Alpino parts are interchangeable but the Alpino baskets use a better grade of aluminum which is much more durable. Ebay in England seems to be a good scource for the things.

Almost all of these engines also had worn out gearbox output shafts where the front sprocket resides. Franky had to have his welded on in his travels through north Africa as it had completely destroyed itself. Why this happens with the ORs and not so much to the Alpinos is another mystery. I welded the material back on but haven't had any luck finding the appropriate cutter to clean up the splines. Once I get this sorted I'll say something.

I'm now able to get first oversize pistons for the ORs. OCT here in Germany sells either the original 76 or a full 77mm Asso. The 1mm is nice but the guy boring the cylinders can get expensive and what do you do when the 77s are also out of limit? 76.4 cleans up most of the normal wear and tear and I can order pistons for almost any desired size.

I'm in the process of building an OR for my wife. I wouldn't go so far to say she's vertically challenged but she's not the tallest camper in the campground so I'm trying to get Wilbers to make an appropriate shock but 7mm shorter. This will equate to a 3 centimeter drop in height in the rear. Together with a slightly flatter seat and 3 centimeter top-out spacers in the fork she should be well settled. Also more to follow.

Cynthia's Atlas is a third series with the exhaust going around the left of the engine. I have an earlier version to use for the moment but I would like to have the later one. I have a couple of scources to build exhaust parts but I need to have several sets made for these guys to produce them at a reasonable cost. If anyone has interest please let me know.

We'll see you all in May in Belgium.

Cheers,
Tom

Hi Tom,

Hagon can make a shorter shock for the Atlas.

Interesting observations about the quality of Atlas parts compared to the 500's. I think my experience with the starter gear and resulting sprag clutch issues supports this. Never heard of the same problem with 500's so presumably the Atlas gear is made of chocolate - is this gear the same on a 500?

Look forward to meeting up in May.

Nick :-)

PostSubject: Front Sprocket   Sun Mar 06, 2011 10:25 am

Hello Tom!

I had the same problem on my solo Atlas during a trip to the Isle of Man races in 2005. I had my sprocket welded on the shaft and it still is today. Now the sprocket is worn and I will try to separate things to weld a new one on the shaft.

Bye

Thomas

Hi Nick. I tried a set of Hagons on my Alpino and I have to admit to not being very impressed by them. Fortunately the Alpinos are light and the shocks cope with it but there's still a lot of movement from the back. Granted for €200 you are not getting a set of Öhlins and they are a big improvement over the dead Konis the bike came with. For a little bit more money you get a much better quality unit with the Wilbers.

Yep the Hagon is a cheap shock but don't confuse it with the stuff that is put on 'classics' - let's face it these are more for the look than function.

The Hagon mono-shock is rebound and preload adjustable has the option of a remote preload adjuster knob and a two year guarantee. Hagon will customise the shock for length and put on a spring to suit your preference. The shock can also be rebuilt unlike the original and some replacement shocks so could last a lifetime.

When I first put it on the Atlas it was set softer than I normally ride with but I was impressed at how well it soaked up the pot holes but didn't pogo. I wound up all the dials when I did some two up work and never got round to putting it back to how it was when I got it - a point commented on by a Morini Camel riding friend who swung a leg over it.

The folk at Hagon seemed pretty confident in their product and if you are an average rider like me then you won't be disappointed. Infact if like me you are an experienced triple pilot you'll be amazed at how much better an Atlas handles - they leave any triple through the twisties hey?

See you at the Rally.

Nick :-)
