grib Posted October 27, 2015 Report Share Posted October 27, 2015 My daughter has been pestering me for a trials bike so I have bought her a Rev 50. I have taken the water pump apart and the impeller looks like it is worn away. Can anyone tell me if this is what a Rev 50 impeller should look like please?

spenser Posted October 29, 2015 Report Share Posted October 29, 2015 It does not look worn to me. Was the bike overheating? Spencer Quote Link to comment Share on other sites More sharing options...
grib Posted October 29, 2015 Author Report Share Posted October 29, 2015 It wasn't overheating but the fan was wired to run constantly as the thermo-switch was not working. I just expected the vanes on the impeller to stick out more than this. Quote Link to comment Share on other sites More sharing options...
