I got my (new) '83 Kawasaki KZ-750 in March, and I'm pretty happy with it so far (2200 miles). Since this is my first bike, there are some things I don't know how to gauge, like how the engine acts when the weather sucks (like cold and/or humid, as it often is here in Boston). Tonight, riding home, even after letting it warm up (choked) 3-5 minutes, it was definitely sputtering when I throttled up. What sorts of changes in behavior should I expect with changes in humidity and temperature? Thanx to anyone who can describe these effects. Random

Thanx to >anyone who can describe these effects. >Random It is hard to tell what is happening with your bike not hearing it but "sputtering" sounds like to me that you are describing a too rich condition. The engine runs heavy and black smoke comes from the exhaust pipes. It has no power. That is the condition when you have the choke on too long or too much. Try backing the choke lever off just a little until the engine sounds better. Too lean of a mixture or turning off the choke too soon will cause the engine to "hunt" and sometimes backfires through the carburetors. Sometimes when you try to accelerate it will momentarily quit like you turned off the ignition for a half of a second. If the problem is not in the range of the choke, ie. you have the choke all the way off and it still is too rich, then take it back to your dealer and get the carbs adjusted. It is a fairly simple adjustment and you will like your new bike a whole bunch more. Bill Landsborough ---- "Love is patient and kind; love is not jealous or boastful; it is not arrogant or rude...

On my last three bikes (all Hondas), I have found that this balkiness when cold and/or when humidity is high seems to be caused by the paper air filter. I have had very good results with K&N direct replacement filters (same shape as stock filter; *not* the little things that clamp onto the carbs). Harvey S. Cohen, mtuxo!hsc, Lincroft, NJ

Cohen, mtuxo!hsc, Lincroft, NJ That did not solve my problem with my first bike, a Honda 550 Supersport. Touring in the northwest was a real pain since the bike ran very rough whenever it was damp even after the paper filter was replaced with a K&N. The solution I finally found was to buy a BMW..... -- Pria ...!{ihnp4,hplabs,amd,nsc}!amdahl!pag00 (408) 746 7539 (Disclaimer: even I don't necessarily agree!)

The solution I finally found was to buy a BMW..... > -- I had this stop/go problem with my Honda CB175 and CB400 in England and eventually found that the insulation on the coils where the cables entered had broken down slightly and that with a combination of road muck and rain caused them to short out. I removed the coils ( in their black plastic case) washed them and dried them completely, then wrapped them in thick plastic bags and never had a problem again. Apparently this was very common with Honda CB models where any salt was used on the road. Bob Palin, Varian Instruments, Walnut Creek, Ca. zehntel!varian!bob
