One cylinder acting up and it's driving me to drink (short ride that it is). Here's the deal. It's a Suzuki Intruder VS 800 that sat for two years. I bought it cheap and don't mind working on it, but I'm stuck. I've done all the typical things.
Drained the fuel
cleaned the carbs and jets ( did not remove off the lines so I didn't lose sync)
flushed and reloaded fluids, e.g. break, clutch, oil, ect...
changed the plugs, inspected, but did not change the air cleaner...
and I still have the rear cyclinder running like I have a blocked mid range jet in the carb? The suspect cylinder runs fine if I run carb cleaner into the carb through the over flow...
I have spark. I changed the number two plug again because it looked fouled white...then reduced the air flow to that cylinder and I thought it worked, but alas..same problem. I can blow through all of the jets and drink shots out of the carb bowl it's so clean. Yet when I take it down the road the rear cylinder cuts out and coughs when heading into the mid range. It's no time at all I'm riding a one lung bike while in mid range. If I kick the throttle up to high range the cylinder works fine and the bike runs like brand new?
I'm looking for someone smarter than me on this one. Is there a port to the cylinder I don't know about for mid range? I will look forward to any insight anyone can give me.
Thanks
Tom
I read in the manual I bought the carbs have to be vacum sync'ed to operate together. There's to issues with that...I don't have a vacum pressure gauge and I don't know how to do it nor the specs. If I did I could removed the carbs of the lines and boil them for good measure.
