i have a new sp450 and this is the first new atv i have ever owned so i am a little nervous about breaking the engine in right, the manual is a little help on this, and also what should the rpm's be at idle, 5mph, 15mph, etc, thanks in advance for the help and any tips

 

First off dont let it idle more then you have to when new, the rings need to be properly seated to the skirt, run it hard in lower rpms you odnt want your engine to be screamin when its new either... you engine should idle right around 1200 rpms +- 50 to 100


Just think of breaking your engine in as bangin for the first time... you dont want to ram it in too hard lol [img]i/expressions/face-icon-small-wink.gif[/img]

Just don't go down on it. lol[img]i/expressions/face-icon-small-happy.gif[/img] Not the first time out. lmao

 

what speed should i not go over in the first few hours,should i ride mostly in low or more in high? and does anyone know what the redline is rpm wise ? when i fist rode it at about 15mph the rpm was around 4000, is that normal? but it seemed to idel at 1100, thanks

 

revv limiter is around 7000 rpms, i would not do over 45 mph and dont forget to vary the throttle and engine rpms

 

Ride it like you stole it! Like polaris500 said get on it hard, vary your speed and throttle but dont go ***** out for long periods. The more you get on it when new the better it will run.

 

I agree, dont baby it , ride it like you want it to run and change the oil at 500 or fewer miles, it will last a long time.

Well Disco after spending about 20 mins trying to remember where I saw this site and then taking the time to give you a quick link. Did it help. You never came back and said.....

 

I read the link above. I had heard this before for 4-stroke boat motors but never knew why. Makes sence when you think about it. Thanks
