Haven't been in here for ages ...!
Winter's coming and it's time to put the GSXR in the garage and get the Katy out again - this thime though I have a little project.
I recently picked up a 540 barrel and piston for next to nothing - and there's nothing wrong with it either apart from some minor scuffing where the piston picked up a little. To go with that I have an FCR39 MX heaved off a 450 suzuki or something..
Anyhoo, I was thinking that it might be a relatively straightforward transplant onto the 400 crankcase but am struggling to find any information about this particular conversion.
Does anyone have any thoughts or ideas??
