Hey Toon,how's it going.
If, you've got a spur you may aswell use it.The problem you had looks like the slipper overheating.The strobe can actually be run as a slipper without over heating.
With regard to gearing it does sound like you may need to gear up a little rather than down.
Maybe this is of some help

Let us know how you like those tyres.i'm thinking about maybe trying the XTM XLB wheels and tyres.
Oh yeah,did you hear about the offer we've put in for Michael Owen.Record offer for the club so it must be over £15 million.
