If would prefer drilling. If you use a 5 mm drill, the hole in the rubber will be quite less than that 5 mm. It will be dificult to enter a M5 screw or adapter. But it will seal very well. I don´t remember well but think that at the end I had to use a bigger drill than the thread of the adapter

A bent conrod will not be caused only by a broken cambelt :roll: Cilinder and pistons are the nikasil ones, conrods are not the ones from the 350 1st series. If you want to place the motor with its electric starter in a street model frame there might be some trouble (maybe easier in the older, not b...

I´ve done that the same way as 72 degrees and it worked without any problems for years. Just make sure that the screw does not enter in the manifold canal. If I rememer it well, I´ve added an O-ring underneath the head of a simple allen screw. There are some special "plugs" to seal the hol...

I totaly agree! It´s a lot of work trying to reorder such a forum and also would suggest to leave it as it is :wink: I only wanted to show you the structure of our ital-web, that is realy nice. When we changed to this software we already nearly had this structure before. When the spanish Lamanta sit...

If any of the two taps let pass the fuel correctly there should be no difference if you open one or both taps (as long as the conecting fuel tube between the two carbs and their integrated filters are ok). Sometimes there are problems with the electric tap if they are not operating as they should. M...

Have you had a look at the german web-site? i think it has a very good structure. 350 and 500 tecnic in the same department that is divided up in motor, electric, framework ... That makes it easy to find and extend subjects even without the search function. If people have the disciplin to choose a c...

Hey Joe, that´s fine you´ve found a more dished plate :D If it has become flat it´s realy a pain to start from being parked! It seem´s that this problem appears more often with 500 than 350, although the clutch is exactly the same (with the only diference of the bore in the center hub). When will ta...

Do the enter hub have deep marks from the metal plates? If so you can pas a file to make it a bit better. And the second important thing is that one metal plates is still curved/domed! If I remember it well this plate is a bit thinner than the other ones. It used to become a bit blue from heat. If t...

That´s fine!

Hans,
are you burning or swimming right now?

It should be 18 x 2,5 mm

I was talking about the "ignition coil" of the stator. Normaly it´s the one that is wrapped in a yelloy plasic foil. From this coil goes the gren wire to the boxes under the tank via the central electric port under the right side cover. All the other coils of the stator don´t have any infl...

Ma experience is that starting problems begin with less than 170-180 ohm on the ignition coil/green wire. I´ve never had a coil with 300 ohm.

I measure 31,6 / 31,7 mm outer diameter

The only stuff (of all the things I´ve tested) that worked was "Restom 4030". This is not longer available The successor is Restom 4031. A friend of mine told me that it also works
