    go for your life 2007 didnt have them anyway, why would you even consider not riding it? to be honest the hole is that small anyway and dont think it makes that big of a difference with the valve fitted as the water is then only pushed out through one of the other outlets.

    yep, just let the old girl warm up and cool down properly. no stopping sudden after a wot run, then starting back up ten minutes latter to full noise.

    The warmup is ok but stopping for fuel halfway thru a 100 mile endurance makes it hard to do a good cool down. The trigger is pulled hard back against he grip long before the engine fires back up again after fueling. Anyone still trialing different pump fed water-in routing to try and warm up water before the head takes a hit?

    Sounds like where I just moved from, only other side of Aus. No winter. Very hot summer. Oh well back to reality.
