rxp/rxt motor vs mods and life expectency?

[CarFanatic]

ok, so I"ve been on these boards for a few months, and I have read quite a few posts about people loosing compression in a cylender with not many hours on the motor. I'm just really curious to know how reliable these motors are?? Being a 4stroke, you would think it be just like a car motor and run forever if maintained?? Then I read a post saying one guy was buring oil at 100hrs and he has a stage 2. I got to thinking well most of these mods are pretty straight foreward items, just like modifying a car, I dont see why there would be a negative affect to life,(unless you have a crazy setup or tons of boost) if the A/F/R's are correct. Basically I'm just concerend because I want the ski to last and not have to worry about pulling the motor out of 11k ski in a year or so to rebuild it! Maybe thats why you only get a year warrenty becuase brp knows they dont last????

what have you more experenced 4tec guys experenced??

I had 145 hours on my heavily modified motor when i ripped it apart for the build up to the EMS system. The engine looked brand new and had 135 psi compression across the board.

Ride more... worry less!

Just turned 200 hours on my 04 RXP. I don't plan on doing a rebuild until 300+ hours if all goes well.

180 hrs on mine runs great not a single component failed yet.

I have over 320 hrs on my heavilly modded 04' RXP..No engine problems even with a "B" kit SC and 8600 rev limit

Just keep changing the oil often, and keep out any water injestion, and it should last a very long time.

oil changes not a problem, about how many hours you guys change yours at? I hope once I get my riva intake, I dont have any injestion issues ever!

My guess is a properly maintained stock or mildly modified machine should see 1000+ hours before the engine needs a rebuild.

how many hours do you guys change the oil?? 10? 20? 50?
