What can i use to clean the engine of my bike to make it look better such as my engin block and all the little parts like the clutch cable things like that water and bike cleaner just wont cut it... if i buy an engine degreaser which one do i buy and when i have it do i just spray it all over my engine and then scrub what i can reach then hose it off??

I always like Gunk and brush it on. some bottle brushes and toothbrushes help too

As above, bottle brushes are your friend, go to your local pound shop and buy a set plus they usually do a pack of awful paint brushes that are only good for engine cleaning. I used their oven cleaner on my engine and it cleaned all the crap off plus it just loves grease..!
