Post 600 Bandit Carb

I own an old 600 Bandit. The carbs recently died and it was going to be a fortune to fix so I simply bought a set that had been taken out of a working bike. Having replaced the carbs the bike will now not start. Any ideas what my next step should be? Do I need to adjust the needles/jets/etc?

Thanks
Emmet

Air, Fuel, Spark, Compression, Timing - jack-up any one of those; the engine doesn't run. I would say you're missing at least one.

So what exactly happened when "the carbs died." That's not a phrase you hear often around the motorcycle repair shop. Batteries die. Carbs get out of adjustment, gum up, leak, move to Idaho.

Of course you're going to need to adjust the needles and jets. Just bolting up a set of used (or even brand new) carbs won't work. It's not like screwing in a new lightbulb. You should go to a mechanic.

Make sure you hooked up everything correctly. While the new carbs may need some tweaking they should still allow the bike to start if they came off of a running bike.

Thanks everyone for your comments. They were all helpful. I am pleased to say that thanks to your guidance my bike is working properly again. I changed the sparkplugs and replaced a fuel hose that kept kinking limiting the petrol flow.

Kenneth: carb death - 1 of the diaphrams ruptured and the other 3 had stretched so much they would need replacing. On top of this the whole unit would need a thourough cleaning. It was just too expensive so I scraped them.

Ah, in other words: someone got Carb Cleaner on the Diaphragms........

(Carb Cleaner makes those rubba' parts stretch-out - you should NEVER clean the diaphragms with solvents)
