    GTX RFI cooling ???

    Can I safely bypass the cooling channel at the bottom of the crankcase? Will the crank get too hot ? Or, should it be fine for everyday riding?

    On a carbed engine the fuel is sucked right into the case, cooling the crank.

    On the RFI the fuel never reaches the crank since it is injected into the cylinder at the transfer port.

    This and the fact that they run very lean compared to a carbed engine is why they have case coolers on the RFI and DI engines. There is also a cooler for the mag because they run a lot more power out of the mags than the carbed engines do.

    IMO, it would not be a good idea.

    why change it. there is no advantage to it. they are great cruisers but that is all you can really do with the rfi. I had two and they were great great fuel econ. you can not really modify them .

    It was leaking water down there. I pulled the engine today and the water channel had about a 2" crack on it. It was not winterized properly by the owner. My buddy welded it up today, and I'll true it tomorrow then start putting it all back together.

    Good deal.

    A buddy who welds is a great thing.
