Modded my 06' GPR1300, now it is slower.
Hey guys,
I recently modded my 06 GPR and now it is slower than ever. I purchased - RIVA Pump Seal Kit, RIVA Top Loader Intake Grate, Solas 14/20 Impeller, Riva Ride Plate. Install went well, not sure what went wrong.
It doesn't really pull until around 30mph, very slow off the start however. Top end I did gain about 5mph, dreamometer says 78 was top speed. Takes a very long time to get to the top speed however.
Please help?

Your setup has changed for more top speed so it wont take off as fast now but a Leo's holeshot kit would help improve that and prop might be to tall.

It is not cavitating is it? Just not as quick. You also went from a stock grate?

13\19 would be better unless you get into the motor with a milled head, and fuel controller, remove the CAT and install a D plate and tune from there... those bolts ons that you have are meant more for hook up and will load the pump more, add the fact that you stuffed a 14\20 in there and you don`t have enough azz to use that combo... leo`s holeshot won`t help with bottom end with that impeller, however it will make you plane out quicker with the right set up to support leo`s mod.
your next 2 mods should be a TINY TACH, and a handheld or bar mounted GPS. disregard what the drsamometer says, there are notorious for being 5+ mph off...
you could also change the venturi nozzle to an 87mm to loosen her up a tad.

Cavitation is a pressure conversion on the edge of the prop, boiling the water at low temps, causing air bubbles and ultimately losing thrust.
