Dear all,

A question.

I am fitting a GSXR1100WP engine (water cooled model, 1993 year) to my Phoenix.

The bonnet won't close by maybe and inch to give you the scale of the problem, it will close but only with some force (maybe 10kg weight). The bonnet that I have has some history, but basically I can take a few mm out of it (thinning), but I don't really (rather than really don't) want to redo it (i.e. cut another hole) as it looks nice at the moment and in my mind it is "finished".

I can't lower or rotate the engine, as it is in the right place and the sump would be too low, and the exhaust angles would all go wrong (given the top tube). Also the craddle is all made and working.


The clash is on the "cylinder head cover breather", which is a big old aluminium block that basically contains a labyrinth of passages intended to allow the oil out of the air before the air leaves the engine (to the carbs, or to be vented in my case). This unit is about 25mm in height and would normally sit under the fuel tank (on the bike). http://alpha-sports.com/supr/1993%20GSXR1100/18.htm
So,
Can I take off this breather, plate it, and then use a cam-chain breather (basically a breather that attaches to the oil filler hole). That would buy me the distance that I need. I don't know much about bike engines, but the 'busa doesn't have a breather on the cylinder head cover (it has a crankshaft one), which is basically what I will have.

At the moment I have rashly purchased a breather from an earlier model of bike (GSXR750, which is slimmer and MAY have the same bolt spacing), but I suspect it might not fit, or will not gain me the required space.


I think that I have my thoughts straight on this, but any wisdom would be appreciated.

Thanks,


Matt

p.s. no, I don't have a dry sump (in that case I agree the problem goes away).
