ok in my opinion... and dont´t get me wrong I have a couple of these bikes and they are great fun, but if it needs as much work ars you are talking about... the only way I would pay$600 for it is if it had less than say 2k miles, I picked up my 74 CL all it needed was carb rebulds and I paid $275 for it, it had 9k miles on it with new plugs, wires, tires, points, condensors battery etc. Anyways, off the subject....First, you need 2 carb kits, and when tearing down the carbs... do one at a time, mae sure you get every single little hole cleaned out.. every brass set cleaned and then I usually coat everything with Marvel Mystery Oil... be very careful of the diaphram, these are CV carbs and pretty much suck in my opinion... when you inspect the diaphrams you want to feel the rubber for elasticity, be careful not to tear though, and if there is a tear, you can attempt to fix with superglue, make sure it is very clean (wipe and spray with carb cleaner, let dry then apply glue) If you can´t fix with superglue then you have to track some new ones down.. they usually run about $30 each. Before you tear anything down, get a haynes manual on the 360´s USE IT. take your time and keep at it you´ll get it done, I have a spare set of carbs I have not rebuilt yet so if you have any problems or break or lose anything get in touch with me. The manual will help you set your points and timing and valves... be absolutely sure that you torque the lockdown nuts on your valve tappets, I´ve noticed if you don´t lock them enough they have a tendancy to slip a bit and hold your intakes open enough to lose your compression... not a wonderful time.
