Hi all,
I have been a rider for a while going through yami rx100 and progressively getting bigger but stopped as far as the 600 and stopped ridin for good amount of years but recently started riding again, picked up a 93 kat 600, shops treated me like I had the plague..lol. I love the bike though so I have started to get back into fixing things that are in my capacity to do. The problems that I had when I got the bike :

a) wasnt turning over.....pulled the plugs cleaned them....( 1 & 2 plugs black, so im assuming running rich).....fixed start problems
b) idle problem........fiddle w/ the idle screw............temp idle fix
c) RMP's thru the roof when handlebars cranked left or right.........tank off readjusted throttle cable closers so that didnt catch on anything........temp fix
d) Horrible milage 200km/ tank (can smell the fuel thru the exhaust)........put in carb cleaner....(no effect)

Things that I have done since :
- 4 new plugs (NGK)
- engine flush
- oil / filter change (amsoil 3.8 liters)
- air filter cleaned (has a K& N installed)

Things that I have noticed since doing this minor tune up the bike came back to life, power on all gear no more boggin no lazy take off basically bike felt like a new bike. so heres where the things that are toubling me, I rode it for 2 days since the minor tune up and loved every moment of it. Took it for a short ride 10 miles each way last night and noticed a bit of jerking when the throttle was opened up(think its misfiring on the 1&2 cyclinders). Today noticed that my oil level was almost non existent( checked for leaks, spots on floor) bike was burning oil, blowing short burst of black smoke from tail pipe (still fuel smell in exhaust too).

Things to get fixed by a shop:
- clean and sync carbs
- full maintenance
anything else that i should get them to look at??

Sorry for the essay but i felt id give you guys an indepth situation report so that it would help diagnose the problem if anyone had the same problem with their kats. I would like to thank everyone in advance for their input and advice or solutions.
