Gsxr 400 gk73A camshaft problem

[hosay57]

Hi guys. Well basically my friend's bike has been seeming like its been running on 3 cyclinders and wouldn't rev properly untill about 6-7k and then it would run ok untill the other day when It developed a loud ticking noise from the top end, unfortunatly he kept riding it and now it won't rev up at all. We've had the rocker cover off and the camshaft lobe on the exhaust side of the 2nd cylinder has very obviously not been wearing evenly as you can clearly see a slanted line across it. Is this a common fault and where can I get a replacement camshaft? thanks

I think i have a set of cams somewhere if your stuck.
They dont usually have problems with cams so check the oil feeds are clear.
Will pump up through the pipes that fit behind the carbs.
