well as i previously posted my trackbike purchase has turned out to be a bit of a lemon,!

what with the gearbox problem and the engine putting out shit power, after bouncing a few ideas about, the general opinion was not to bother throwing effort and money at it with a transmission overhaul and engine refresh, as this would end up being fairly costly. Instead i was advised to junk the old lump and pick up another. Well after a bit of homework it appears that the 2003 zx6rr and the 2003 zx636 other than parts associated with displacement ( crank,rods,piston,cams) everything else on the two bikes is the same including cylinder head and injection system. Decided to take the plunge and sourced a low mileage b1h 636 engine ( including ecu as this too is model specific) which i picked up today. I realise i will be losing the slipper clutch but as i,ve never ridden with one before i ain`t gonna miss it, and i think i would prefer the extra mid range of the 636 anyway. It,s being fitted this afty so i will report back 2morra with the progress. In the meantime if anyone just happens to have any pointers or potential problems with the switch, please give us reply, cheers.
