Hey all,
this is my first post on the forum, hoping you all will have some wisdom to help me out here.
I have a 1975 CB350, it was given to me by my uncle and it has sat in my parents barn out of sight and out of mind for the last 4 years or so while i have been working on my degrees. I have been making an effort to get it running again. So far i have replaced the battery, cleaned the carbs, and put in new plugs. The bike at this point will idle with a little convincing, but it dies if you give it the slightest amount of throttle. I noticed that the exhaust coming from the left side is cool, while the right side is warm. I have tried cleaning the carbs a couple more times thinking it was a lack of fuel supply, but nothing seems to help. My dad noticed the crankcase was under pressure when it was idling, and he think that the rings in the left cylinder are stuck to the piston, so it is not getting any compression. I do not have a compression gauge, nor do i have access to one. Does this seem like a likely diagnosis? I am wroth to drop the engine and do a rebuild or disassembly. I have a tough schedule and will be transferring to a school where i will not have access to a garage or shop to store the bike, so it will go back to my parents till next summer if i do not get it working.
Any thoughts are much appreciated, or things to try that might help.
edit: just pulled the drain plug in prep for an oil change, quite a bit of fuel was in the crank case. To my knowledge this reinforces the lack of compression theory?
thanks,
zeke
