well...I changed the coolant and then the temp display started to jump 4-6 deg back and forth...then the bike over heated...I added around 2300 ml and my bike holds 25-2600 ml (gsxr600 - 00) on the initial...so removed rad cap after bike cooled down and started bike on idle...the water pump is working because could see fluid enter rad. So I am ass-u-me-ing that there must be an airlock. Any iddea as to what else it could be?
Thanks
