wants to start....

Hey everyone, I have a 77 gs550 which i've had since last season. Its a great strong bike. When it was time to drain the gas over the winter, I guess I did it from the feul filter side, not the carbs and messed it all up. I took it to a mechanic to have the carbs cleaned out. Picked up the bike, we got it started, it started reluctantly. Rode it around for a while, she purred like a kitten. Went home for about an hour, went back out and no start...the engine turns, and revs to about 4000 rpms then craps out. I did notice that they also replaced my feul filter, but it is a lot smaller than the one that was there before. Could that have anything to do with it? AND to make matters worse, they came to pick up the bike and called me 20 minutes later saying that it started right up. I took it to work that night, it sat for 8 hrs and the same thing happened to me...rev then crap out and nothing, not even a push start helped.
any ideas?????[-o<

Yes, some filters ARE too restrictive for our bikes.
Instead of playing guessing games:
For a sanity check, get a big transparent fuel filter (automotive style) and transparent fuel lines so that you can see if the fuel is actually flowing in all operating conditions.
Some bikes have a filter/screen in the tank itself which makes an external filter unnecessary.

Lose the filter. The petcock has a very fine screen that negates the use of an inline filter. The new filter you have is most likely restricting the fuel flow. Try a straight fuel line from the p/c to the carbs.
