    GPR HO pump

    Hello all....got a sweet deal on a HO pump that I will be installing on my 00 1200r. My current pump is of course stock, and I'd like to know which exit nozzle is preferable.....the 87mm, which is what I have on my current pump, or the 85mm exit nozzle. What effect will the 87mm nozzle have if I install it for now? Thanks!

    I think I read that the 85 was more desirable, maybe boring it slightly larger as well, 86mm?? Don't forget the longer cables or cable extensions if you are running the spacer on a 2000-2002 ski. Nothing worse than getting mid project and missing parts.

    I thought the 2002 ski was the only one needing a spacer? I was under the assumption on a 2000 it would swap right over

    On a 2002 to use it without the spacer you need a different midshaft. 2002 has the shorter odd size driveshaft. With the spacer it will be a direct bolt up for you, but you need 2003 and later cables to accommodate for the longer pump since it now has a 2" spacer. If this is confusing you I can PM you my number and try to explain it over the phone.
