Greetings from Montreal =)

Just picked up this beauty, and when I say picked up I mean pushed 5kms - doesn't start, dead battery but clean as a whistle. Not sure I've ever looked forward to winter so enthusiastically!

Apart from the work I did on my Yamaha V Star 1100 Custom, this will be the first work I've done on a bike and I'm really looking forward to it. This forum looks like a great place to hang out, and I'm sure I'll be needing the benefit of your collected wisdom as I get into this project.

Got a cafe racer build in mind, Clymers manual in the post and enough ambition to keep grinning =)

Have a good one, and see you around,

- J

Thanks Cookies! I'm pretty stoked - hooked up a working battery to the bike and at least the electricals seem to be ok (headlights and starter motor anyway)...will be buying a new set of spark plugs and some carb cleaner today, give her some new gas and see if I can get her to start up. Watch this space =)

I wouldn't spray any carb cleaner anywhere around your carbs .

Carb cleaner is very rough on anything resembling rubber . There are essential bits in and around your carbs that are at risk of destruction .

I don't even buy it anymore .

Use brake cleaner instead. It evaporates faster and isn't nearly as hard on rubber as carb cleaners. It also washes the shellac/varnish/goo right off.

If the carbs really need cleaning, spraying some stuff in them won't do anything to fix the problem, and could make it worse. They'll need to be removed and soaked and prodded to clean inside the bodies and passages where you can't see and where the dirt is causing the problems.

See the MacGregor Carb Rebuilding Manual link in my sig for details and a good guide to cleaning your carbs.

Thanks for the input guys - I got the carbs out yesterday and found a lot (a LOT) of rust and gunk in the float bowls. By that time I had already emptied a can of carb cleaner in the things, but was careful to remove any gaskets first. They came out pretty clean - basically all I want to do is make sure I can get the bike to start.

Once I've done that then I'll be rebuilding the carbs completely and giving them a thorough clean (Randakk kits apparently are the go-to but any suggestions welcome). A few of the gaskets are pretty worn and some of the jets look rough as a stucco bathtub from their time soaking in the rustgunk in the bowls.

Will get the carbs hooked back up into the bike today and see what gives =)

Jets are usually cleanable, they seldom have permanent damage unless fingers have prevailed. Soaking them in brake cleaner overnight and blowing them out with high pressure air will often clean them up. If not, carb dip will do it.

Well, after a bit of work on the carbs and some Macguyver'd gasket repair I got the old girl started and running - oh the sound of an inline 4! Maybe not Beethoven (yet) but sure beats the Sounds of Silence =)
