New to this

Well i wish i could think of a catchier phrase that would get more attention,
First off hello to everyone, mostly in particulat those of you reading this. Im looking into getting my first bike and have decided on a Commando, but in this am also looking for information on them. I am planning on building a Bobber with it and wanted to look into engines/ drivetrains. From what i have researched i think a 73 would be the way to go with the top end hitting 120mp/hr. However i have read that these were rather leaky and that the later drive trains weren't much better, are there gasket sets one should get? or how does one go about strengthing this engine where it is a highway reliable motor or is it already? Any forums or info would be greatly appreciated and thank you for your time.

Welcome in new_leaf.
Firstly you must have a sense of humour to be aloud in here.
Secondly I suggest you edit the word BOBBER out of you post as some of the tribal elders don't like that kind of talk.
Me however, If it's Norton it's good. Always looking to see new ideas.
Lots of great guys here that like to help and show their handy work.
We all like pics of biuld history.
What do you want in an engine.... Bite you head off power or go every where in top gear. ?
Just thought I'd get this going...

Build them right and they do not leak.

My first "proper" motorcycle was a 1973 850 Commando, I beat on it for 9 years kinda/sorta keeping up on the maintenance, it did not leak (much, a hot Norton will generally mark it's parking space a little-bit).
The bike was all I had for 7 years and let me down 3 times in 9 years.
An oiltight, reliable Commando IS CERTAINLY an attainable-goal just follow the instructions EXACTLY!! and more importantly post pictures of your project.
Bobbers can be a touchy subject, they show the creativity and skill of the owner when done-well but the good-ones are VASTLY outnumbered by the bikes that are just "there" and that would be a waste of a Commando.

Welcome to the forum.

As was stated, build it right and it won't leak (much).

Year is unimportant, except if you have a '72 with the "C" (combat) stamp on the head. You must ensure it has the proper "Superblend" bearing refitment, pistons that don't have the crossover oiler slots cut into the sides, and modification to the crankcase sump to improve oil flow.

Thanks, AC, that made me smile

We're all gentleman here.
Or are we ?
Am I the only one that wonders..... Are there any ladies present ?

Oh yeah... Go for an 850,... Torquey, mild compression, go all day and all night.
Show us what your doing.
AC.

73 would be a good choice. They can all leak or they can all be tight. It all depend on your abilities. Preparation, common sense, luck, and proper procedures.

Don't be set on size, a tuned 750 will kick an 850 ass and can be made dependable. An 850
is actually punched 750 at 823 cc's.

Stick with the "Cafe Racer" label and mention "Commando" once in a while and they won't stick you in the "other" category.

Study up on the Cafe Racer genre, it might be just what you are looking for. Performance, customizing and a very rich and colorful history.

Also be sure to check out Jockey Journal, a bobber haven. :mrgreen:
