Bahamas zx6r mystical overheating problem.
Hello all. I have the strangest overheating problem and living here in the bahamas is no help as there are no decent mechanics that are familiar with motorcycles here, so I have decided to tackle the issue my self after hrs and hrs of reasearch.
Bike was purchased from a friend with an overheating problem. At first I assumed it would be an easy fix as I knew it had a leaking radiator. While replacing the radiator it became apparent that the previour owner had been filling the bike with hard tap water ( very hard here in the bahamas) and all the hoses were full of gunk and calcium deposits. It was all cleaned out and flushed.
So radiator was changed still overheating 230+ while riding at decent speed
water pump replaced with decent used one and brand new impeller...still over heating
Themostat tested and removed.... still over heating
Oil cooler replaced as it had failed.. still over heating.
As a last resort I changed the head gasket and there is still no change. Checked the head and block for warp as per manual and it checked out fine. Heres a pic of the heads after a bit of cleaning.
Bike has lots of power
The strangest thing that I have been noticing is that while at idle the temp will hit 209 fan will come on and temp will drop to 204 200 while on kickstand but if I hold the bike up right while sitting on it the temp will rise pretty quick to 220 225 and if I lean it back on the kick stand again the temp will drop back around 206 200. Also the temp readings are very sparatic , while at idle the temp will hop back and forth 198 212 205 200 211. While riding its more like 218 225 214 230 228 238 224 240
Very strange any input will be appreciated
Sorry for the long post but I wanted to give detail.
Please help me out this beautiful bike sitting in my garage is killing me because I cant ride.
