Right following on from this, what actually is the stock compression ratio of the RFV engine? I've heard anything from 8.5:1 to the above 10.4:1
Also am I correct that the factory head gaskets are 1.15mm compressed? Looking at head gaskets & depending on the answers to the above, deciding what thickness to go with.
Assuming I'm correct on the HG thickness and that standard CR is 9.5:1 (which seems to be the most commonly stated ratio when looking up RFV) I'm probably going to go with either a Cometic 3mm HG (giving around 8.2:1 CR) or 2.5mm (approx 8.,5:1) but confrimation of the standard numbers from those in the know would be appreciated since there's a £50-odd difference in the price and they're a special order.
Thanks
EDIT- Also, given the crank interchangeability between engines would I be able to order a generic big end/main bearing set listed for pretty much any XU/XUD shells or??? Also any preferred brands amongst engine builders here, I'm seeing Glyco come up a fair bit but have also seen a company called King who seem to be decent. (given how cheap bearings are in general, and the fact the engine is on 160k I'm planning to refresh it before building on it so new bearings, hopefully bores are in spec to just hone and re-ring)
