hey i was just wondering how long it takes to break-in a 440. :confused:

go easy for half a day then hammer it the rest. TRUST ME;)

Hammer it all day, change the oil after about 2 hours. Then again at about 10 and 20. Run it like you normally would just not at full throttle for more than 10-20 secs. You need to load the rings to get them to seal properly, and nothing does that better than on and off the gas alot.

so what is it go ride it like normal all day or baby it then hammer it

I've always used this method.

dont be afraid to give it ****, just dont max out the throttle. 3/4 range. do alot of high speed de-accelerations as it is good for break in. Warm it up completely before doing so.

Just don't go bouncing off the rev limiter

I did what JE told me - low to mid throttle - don't keep at one rpm -always be moving throttle to keep rpm's moving up & down - when head gets hot shut down and wait untill it completely cools down - then repeat - called "heat cycling" -do that as many times possible (in neutral) before ya' actually ride it & put a load on the motor - I did like 6-7 heat cycles and rode it without reving it up too much the 1st day and then just rode it normal -so far have raced it for 3 years w/ no probs at all
