Yes, I'm guilty. :confused2: Let it sit too long while I enjoyed my other motorcycles and other diversions. She was a cherry when I bought her from her first owner in JAN 2001, with only 4950 miles on her odometer. He had just had her serviced at the local Yamaha dealer and brand new Dunlop tires graced her polished aluminum wheels.
Anyway in the past eight years I've only put an additional 5500 miles on her. She has always run well (fast - faster than I need or want).
She's been tucked in a corner of my gagrage and hard to get to (must move three other motorcyes to get her out). I did get her out recently and low and behold - she was hard to start. Put new plugs in her - still wouldn't idle or run without the choke. :bang head:
Googled the problem and came up with this excellent forum. Tried the "shotgun fix" which improved things some, but she still wouldn't transition
from idle to higher RPM without the choke.
Read some more posts, one give me the idea to check for airleaks and sure enough when I sprayed Carb Cleaner around the intake manifold rubber seals - she increased RPM's.
I thought about this overnight and next morning I loosened up all the clamps holding all four carbs to the intake manifolds. Sprayed the upper rubber lips (where the carb bodies enter with WD40) and let her sit for an hour while I thought about how to get the WD40 down between the carb and the rubber holder where the leaks were occurring.
Then it came to me. :ummm:
With the choke off, key on, hit the starter very briefly while spraying the WD40 around the leaking areas. Did this on each carb, never starting the motor, just using the brief turn over on the engine to draw the WD40 into the leaking areas. After several applications, I tightened up all the carb mounting screws.
She ran very well, but still had several hesitation points while going to higher RMPs. So I used an old tip I had learned many years ago. Spray Carb Cleaner directly into the carbs while increasing the RPM's. Several doses of spray into each carb while I blipped the throttle betwenn idle and 5,000 RPM took all hesitation out of the throttle response.
She's a young lady again; ready to kick up her heels and race down the highway.
Hope this helps someone else to get their neglected ride running right.
