Re: Running Rough

fouled spark plugs?

Bad gas?

When was the last time you cleaned your carbs?

Re: Running Rough

getting to them is harder than cleaning them. Now, I've only ridden fuel injected bikes for a LONG time. But have cleaned many a carb on old cars I've had. Get a good can of carb cleaner from your local auto parts store. Piece of cake.

Getting to then is a doddle

And anything special I need to set them back up, when replacing them?
Cheers

Re: Running Rough

A manual would be a good idea. You should take them apart as far as you can to ensure everthing is clean and free, you will need more than one can of carb cleaner also. I would make sure the floats/needle vavle are set and operating correctly. Perfect time to install a jet kit. The 1st thing to look at is the plugs though.
