The bike has been down for over a month, the last ride I was out it started running worse and worse throughout the ride, and barely made it home. It felt like the ignition was breaking down. I ended up replacing the points and condenser, and still had zero spark.
Today I finally pulled the seat...
These days, I use the big parts washer with solvent for motorcycle/auto parts, and the ultrasonic cleaner for pinball parts. My ultrasonic is too small for most motorcycle bits. It can fit one carb at a time, though.
A buddy and I did about 120 miles yesterday. All was good until somehow the dipstick unscrewed itself and the bike sprayed oil all over itself and my leg.
Luckily I was able to take my buddy’s bike, find a drain plug that fit the threads and get 3 quarts of oil at a local auto parts store...
Time to address the breather box. This is apparently a known issue with the reproduction parts and the fix is to gut the spring loaded flap from inside the box and use a ball valve style breather valve from later model Guzzis.
I cut her open and pulled out the flapper, spring and mounting...
So there is an oil seal there on the crank, although when I swapped out the stator on the GS550 I had, I recall there being some oil in that sidecover too.
The mixture screw will affect only the idle circuit. So if your floats are set correctly and you still need to be 3-4 turns out then I would conclude that the pilot jet is too rich.
Tuning carbs can be tricky but just change one thing at a time, go for a ride and take notes on how it changes...
When you say “four turns out” are you talking about the idle speed or mixture screw? Either way, neither of those are affected by your main jet. Main jet is 3/4 throttle to WOT, so going to a larger main jet will have zero effect on your idle speed. If referring to mixture screw, if it’s on the...
That’s pretty slick. I might steal that idea for mine. I’ve done plenty of rolling with it solo but it is certainly awkward.
