Hello all!! I may be opening a can of worms here but I just got a 03 Baja from a dealer and he just rebuilt the motor and I will be taking delivery with 0 hours on it.. It will be all stock parts and I bought the extended service contract.. What is the "Right" way to make shure I get the rings seated?? Also as I have a tach(this will be a first for me) what should I stay under?? How quick should the oil be changed?? Any other helpful hints?? Any thing to watch for on this model or year?? Yea I know maybe I should have asked before I got it... But I made my choice due to hints on this form soooo I can trust you all...Right??

 

Damn, you're screwed now. LOL j/k

Don't over rev in each gear and don't lug it around. Ride up about 3/4 throttle in each gear and let the motor rev back to normal as you go back down in gears instead of useing the brakes to stop you all the time. Basicaly go out and ride it, have fun, don't baby it but don't rev the crap out of it for the first tank or two. At at least the 10 hour mark (sooner is better) change the oil. After a couple tanks or so of gas and an oil change ride it as hard as you want. jmo. Nice quad by the way. I like the Baja's especialy the 04 X's. I know you have an 03.

 

This is the RIGHT way to break in a motor. Vary throttle RPM under a load from low to high RPM's. Go through the gears and deaccelerate through the gears. Don't be afraid to run it hard. The crutial thing is to vary throttle RPM, don't stay at a constant RPM!! Don't be afraid to rev it, but don't stay at high RPM long! Running it at a varied RPM and running a little hard is the right way to break a motor in. Some people say to do heat cycles ( running it for a little bit, then let it cool off, running it a little... ect. I believe doing heat cycles is a joke and is no way doing anything in your favor except wasting riding time. Remember the first 20min of running time is the MOST IMPORTANT in a break in process. So be sure to let it warm up properly then do what I told you to do. I guarentee your motor will run longer before needing a rebuild, it will run stronger, better, and have more power than breaking it in like a grandma!

I would recommend doing the first oil change within a couple hours (yes I said couple hours) of running time...... You don't want a bunch of metal shavings in your oil!!! Do the second oil change roughly 8-10 hours of running time later.

Also remember during break-in, ride it like your gonna ride it if it didn't need to be broke in EXCEPT, don't hold it at a constant RPM for an extended period of time and don't hold it wide open for an extended period. Letting it rev to a high RPM under a load and deaccelarating under a load is crutial to a proper break-in.....

Now other people might tell you different.... But chose wisely. My DS650 is almost 4 years old and it has the same compression as a new one, doesn't puff ANY and I mean ANY smoke at WOT under NO LOAD, meaning holding it to the rev-limiter in neutral, and it runs better than most! My DS650 WILL beat any other DS650 with the SAME modifications if it's broke in the granny way....... I guarentee my way is the right way.....

Whew!.....[img]i/expressions/face-icon-small-happy.gif[/img]

 

you have a cdi that won't let you rev to high so the tach may not be much use but if you get a woods cdi you will like having it. it does help with tuning you can see what little changes have on rpm.

 

Well, I use the heat cycle method and it works for me ... No Joke! [img]i/expressions/face-icon-small-smile.gif[/img]

 

I guess I'm from the old school...........Ride it like you just stole it...........Ride it the day you buy it like you will ride it while you own it.

I have a 2000 with 1000's of hours and hard miles on it. I got it new and the first ride was up Four Peak (About 26 miles one way), I hammered the throttle all the way.

Befor the next ride I installed the RWR stage 1 kit. I rode in Glamis for three days. My ds has never missed a beat, the compression is perfect and it runs great.

JMO, Good luck.

 

I just got on mine and rode it, I didn't thrash on it but I really didn't worry about it either.

Pushinthelimit,

99.9% of all DSs fit the description that you just gave. The simple fact is that the machine is very durable.

Malinios,

I'd suggest combining all of the info the people here have given you:

1. Keep it under 3/4 throttle, don't bog it & let the engine do the braking.
2. Don't let it sit at any one RPM, keep the RPMs changing constantly.
3. Don't babuy it too much, but also don't ride it so hard as if you were racing in the Baja 1000.
4. We're talking about a metal engine, and heat cycling is a good thing.
5. Change your oil at 10 hours.

6. If you do NONE of these things, your ATV will probably not show ANY problems from it, ever. However I believe everyone who posted has contributed something that I believe is a good idea.
