Dear Expert, As i have perchased a Kawasaki zzr 400 1996 model and its second hand. I am having problems with the bike. First problem is that the engine does not revup as fast as it should. I have to realy pull the throtel a lot. Second prob is when im riding long didtance the bike gets hot and the tapids start nocking badly. The bike does not have the front ferring. I was told that there is an air flow system from the front ferring to the air filter. Its not there. Please help me

Given the year of the bike there are a few things you will need to look over

*Check your break pads for even wear
*Change your break fluid
*Check your clutch lever (it should move about a millimeter before it actatually grabs the clutch)
*That bike has carborators. They need to be cleaned (could be part of problem 1 and 2)
*Check the fuel tank for rust. (there are treatment kits if it is rusted)
*your throttle cable should be lubed with cable lube(part of problem 1)/(when you pull the throttle cable then let go it should snap back closed)
*get higher octain fuel (this will help with problem 2)
