Good afternoon long time listener maybe second time caller.....My back story, owned and wrenched on my own motorcycles since i was 17 now 60. I have been a mechanic all my adult life 20 years out of a toolbox and now another 20 years off the tools in management and training so i know a thing or two and i still consider myself as a mechanic.
I bought a custom hard tailed stretched frame non running project (compete and licensed once runner but sat for years) with an XS650 engine, here is my dilemma, I do not know exactly what year model the power plant is nor the carbs. There are no points, no shaft thru the head and it has a black box (CDI unit) original charging and ignition system with a severely molested harness so this is what i know so far. I have since straightened out the wiring everything rewired and what it didn't need was eliminated. I removed and cleaned the carbs and the bike runs pretty well except i know i need at least one new float (they are brass) but it still runs ok till it sinks....... There are no numbers on these carbs themselves to identify what they are exactly. I bought 2 sets of new brass floats from different vendors online based on visual ID and once installed the bowls interfered with their movement and simply won't float (work) so..... to get the correct set of floats either brass or plastic do i simply just measure the inlet side of the carb to decide what MM they are?
This thing after sitting a couple days i can turn the gas on, set the choke, run the kick thru once or twice, turn on the power and one good kick and bam she's a runnin!!!
After a couple mins running on to a test ride she stumbles and sometimes cracks a little but get her past that and off to the races she goes! like i said my first experience with these engines so any good help and or worthy advice would greatly be appreciated.
I will get it ironed out sooner or later because i always do i would just like it to be sooner......
