Dr Jerry had shimed the both sc's , new ceramic bearings
and metal washers as well as Vortech impellers , i m running both RXP's
foe just 4 hours only after all parts were installed ( only 4 hours )
i m really getting crazy , coz the stock RXP can pass me
by very easy , i hate to say that but this is the truthLast edited by LAB69; 07-01-2007 at 10:58 AM.

My RXP stage one is doing the exact same thing...I am about to ride today after adding oil, it was low, changed spark plugs, and I checked the SC impeller through its intake and could BARELY move it, few mm and then stop....if no improvement I will look a prop pitch and possibly the guts of the S/C....these people can and will help you sooo much...this forum is awesome!

is this the first time you have been out after the install? if so I think you need to send the props to Jerry for tweaking, I had a friend that installed the complete Riva stage 1 wth the 14/17R prop his RPM`s went down to 7800
I rode the ski(RXT) yesterday after Jerry tweaked the prop and it is back to 8080-8100
I think there are alot of props that are off. I have one more tweaked prop to try on another RXT that had the same issue but it will be next week before I get to ride it
so I am betting your props need tweaking

The problems were , i spent allot of money to both RXP's
and at the end i lost power ( RPM ) before i add any parts
i used to get the 7980 rpm but now max rpm is 7550
The first RXP is 2005 is running about 163 hours only.
The 2nd RXP is 2006 is running about 78 huors only .
aaaaaaaaaaaaaaahhhh ,
any way thanx for the help ,,,,,,,,,,,,,,,,,,Last edited by LAB69; 07-01-2007 at 11:06 AM.
