problems

Hello!
I'm Alex from Russia
In the fall of 2005 I bought an old Savage (produced in 1989) The motorcycle was in therunning order, however I have found several faults in it recently.
First, the carburator could not properly hold idler wheels and the engine unwinded very hard. Having looked inside the carburator I have notised two holes in the vacuum diaphragm. I have ordered a new diaphragm but due to very severe cold wheather in Siberia Russia. These days I can't start the motorcycle now. The question in respect of this issue is what else except for diaphragm can negatively affect the work of carburator.
Another and more impotant problem is when the engine is fading I hear a terrible clank of metallic sound somewhere in or around the engine. I can't determine where this sound comes from and where I have to check first.
Sorry, I'm not much experienced motor-mechanic and my questions may sound a bit silly, but I wound be most thankful if someone will give me some ideas on these problems.
Thank you in advance.
Alex

Welcome!

That diaphragm definitely needs replacing and the carb could probably stand a thorough cleaning. Making sure your fuel tank doesn't have a lot of junk in it and that your petc0ck screen is clean are always good on an older bike. I'd install an inline fuel filter along the way as an added filter before the carb. If you get the clear plastic kind, they are also good visual indicators of fuel flow.

About the sound, I don't know. I would suggest that you search this site (using the search function) and look for backlash and see if that sounds like your symptoms.

Whatever it is, check it quickly and don't drive it before you found the problem, because this sounds like a serious problem!

as everyone said before me fix carb first. and by fading i assume you are talking about decelleration. if the metal sound was something real major you would know what it is by now because something would be coming apart. not take it lightly b/c all sound are major. but it could be something as simple as a cover loose and vibrating due to the harmonic change . now i am not a motorcycle mechanic and i have not taking my s40 apart "yet". but i do work on race car engines for a living, and on our stuff when you close the throttle your timing belt will slap the cover due to valve train pressure and change in crankcase harmonics. and as someone said before me check your cam chain. also change your oil and look at it and your filter very well and run a manet through your oil .

Start it and build some oil presure see how it sounds after the diaphram has been installed...
