Hi
What model of GSXR engine is fitted?
How long has the engine been fitted in this car? has it ever run at the correct temp.
the beetle is a rear engine car and is the radiator getting enough cool air thru it, I know all the Suzuki GSXR's that I
Have had dont like to sit in traffic without having air rushing thru the radiator. and thats the radiator positioned just behind the front wheel, loads of fresh air available.
Check that all comb is dirt free and air can circulate ok.
