steam cleaning
 

So, I've got the back end off and I want to make all the egine etc sparkly, should I jet wash or steam clean? Any down sides or thigs I need to do first?

i wouldnt do either i cleaned my engine with just gunk and some rags just takes a bit longer

Agree with Festa. I wouldn't steam or jet wash either.
I use Gunk on the tough stuff, Muc-off and the more softer muck and wash off with one of those plant sprayers. There's a reasonable amount of pressure but not a lot of flow, ie you don't get a lot of water everywhere and they're very controllable as to where the water goes.
the one I got holds 5 litres, you can even fill it with hot water.

If you lurve your bike NEVER use a steam cleaner or jet woshur!

cool - thanks guys, guess I'll have to do it the hard way!

liberall dose of wd40 or duck oil first just to soak into the dried on mucky bits, leave it for half hour then gunk it off. Brings up the casting pretty smart

going to pick some up at nec - boy that shopping list is long!!
