i just bought my 05 rxt from riva and took it to lake ida for my first ride i rode with the learners key only for the first 4 hours on purpose so i wouldnt overdrive it during break in time. after the 4 i put the regular key in and would bring it to 60 mph no higher. i brought it up(according to speedo) to 71 twice. even tho i know its not even close to that. but for most the day i kept it under 4500 rpm's. my average speed according to the display is 18. 5 mph. is this a proper break in period so far even though i have to go to 10 hours? also what mods would every1 recommend that is warranty safe and basic? i dont want the power cooler or anything crazy. thank you

You need to ride the thing hard the first 10 hours, just no substained runs at the same RPM. You want the rings to seal good which won't happen with the learners key or keeping the rpm's so low. Take it out and give it bursts of WOT (wide open throttle) followed by throttle off. So you want to go on off on off on off with the throttle. Once the rpm's hit 7400 or so let off the throttle.
With cars if you don't run them hard the first few miles your compression will usually be low because the rings tend to seat in an oval pattern not allowing complete compression. Same with these doo's. I heard of one guy who ran with the learner key for the first 10hrs and couldn't figure out why his compression was way too low with a new ski. |

It is true what josh said. Remember to vary your rpms up and down. Keep WOT runs only a few seconds.

Just a hint! Rings are seated after 15 mins. Thats it. Manufacturers tell you longer to save their butts on legallities. Tell pro stock, top fuel, NASCAR, that the rings aren`t seated until 250 miles or 10 hrs. Cross hatches are their for the ring to seat. 15 mins,,,,,thats it. I got on mine the 2 hr of operation. I ain`t let off the throttle since.

With a new engine it is not only the rings that have to seat....lots of other parts need proper break in time. Makes me laugh, these guys who beat on a ski after 2 hours, then are mad because stuff broke. Actually, if the dealer checks the computer, they will know how you broke it in and "2 hours" is grounds for voiding the warranty !!

I`d like to know what else has to break in on a bench ran motor? Not the cam, on any motor the cam is already broken in. If not they would tell you to run motor at initial start for 15-20 mins at 2g! Bearings don`t break in. Rings seated are it. Just my motor building experience with rings is 15 mins.

You mean to told me that you make you mufflers with rings and bearings in them. |

I didn`t told you anything. I will tell you that if I only did exhaust I would not be in business therefore the name of my company is Custom Muffler & Auto Repair

engine break-in is always a funny subject. How do you think engine builders test, dyno, and tune turn key crate engines? They certaintly don't run them for 10 hours or 1000 miles pefore they run em hard and tune em. Same with race engines. Sure a race engine may only last 1 race, but they are run at or near redline for hours on end, not something you see on the road or in the lake.

Bravo,,it seems someone else is in the know!

I am one that also believes from my own experience and research that breaking it in hard, i.e. going WOT quite often and while varying the RPM's during the first hours will yield a better performing ski. Check out this web sight for some more back up to this:

Well here I am to answer your remarks !! Sure race engine builders don't spend 1000 miles breaking in their engines....they are maxing performance out of the engine to the extent that after a thousand miles it probably would be ready for a re-build. They are looking to finish only one race, then will completely tear the engine down and rebuild it. Same with the Outboard Drag motors I used to race. With the single piston rings they use, more than a 30 minute "break in" would be taking time away from the few hours these motors live before they are due for tear down.
However, we are not talking about "race" motors when discussing break in for our 4 stroke PWC. To most people longevity is important. If you want to run them balls to the walls after 15 minutes, fine, but be prepared to spend a lot of money on repairs ! And as I said before, todays computers keep a record of how the motor was run and if you blow it, don't count on the warranty to help you pay for repairs. You ask, what parts should be given time to break in....besides the rings? How about the valves. They need time to seat. Modern engines are made to closer tolerences than those from 10 + years ago, but taking it easy and following the manufacturers instructions never hurts. As for the crank being "pre broken in" from bench running the motor...how many production motors are actualy bench run...one in 50 ? Let me set one thing straight, I am not promoting you to "baby" the motor during break in, it needs to be run at different and constantly varying RPM, with short WOT applications...but to beat it to hell after 2 hours is dumb !!

Ok, first off my valves better be properly seated (sealed) before the heads get bolted on. If not then your screwed from jump. Break in a crank? What the hell are you talking about? The journal surface better be perfect before it gets bolted in. If not,,your screwed from jump.
Gonna have to do better than that! I`ll be shootin` from the hip! |

Is this Really relevant, its your ski, break it in as you want. Beat on it or baby it. but this thread is getting ridiculous. I am a newbie to this forum and have gained a lot of knowledge from everyones Q&A's. but its wasting my time to read all this dribble.. Come on people.
|

Break in is VERY important to longevity of any motor. Yeah its relevant. If you don`t wanna read then don`t. This is not a negative thread at all. In fact just to inform people.

I`m still waiting! Give me and my mechanics some knowledge bro,,,PLEASE! Giving out false information is not what this sites about. This message has been edited. Last edited by: RIVA CREW, I`ll be shootin` from the hip! |

Hoss we read this forum to get info (Positive), it is ovoius that this is getting personal, it's very simple, manufactures want us to break-in these units a certain way, they are going to back your warranty not you, yes everybody has they're opinions. unless the people on this forum want to take risks the can follow what your recomending.
