Any of you guys into building engines? I have a question

Well I know its not a truck engine but I figure it should be the same. I just put a big bore kit in my Kawi V twin quad. It consisted of new nikasil'd cylinders, high compression pistons and wrist pins, high lift cams, hd valve springs and hardwelded rocker arms. I assembled everything as manual instructed, cleaned and dryed everything thoroughly, use the right lubes where needed, and checked clearances on everything. Got it all back together and have been doing this break in method per the kit manufacturer. Warm up, ride it hard 15 min. shut down, cool down to the touch and do it again 5 times. Well I changed the oil after each step and after the 3 time I noticed very fine metal shavings in the bottom of the drain pan. So small that is looked like sparkles in the oil. I didn't pay attention the first 2 oil changes. Now I am freaking out that something is going wrong on the inside. It runs strong so I don't know what could be going on. Any suggestions if this is normal while breaking in an engine? I have rebuilt a few chevy motors before but never paid attention to the oil after changing it.

Sorry for the novel but I needed to vent cuz I am freaking out about it:(

got me on that one. have you tried calling the manufacturer?

i think it will be ok it would be like a new car engine everything has to work in a lil i wouldn't stress just yet

dont panic krewz , its ok and completely normal.. thats why you change the oil after each step... once broke in it will go away.. thought the same thing when i put the big bore kit into my bike... car and truck motors do it too just not as bad

It is OK. The motor was just going through the motions and taking care of some minor clearance issues that it may have had from casting marks and other small parts.

Thats what the manufacturer said too but always want a second opinion. They just want to sell more parts! First hand experiences usually tell more than a factory!

THanks for the input, maybe I can sleep tonight HAHA

yea it's clearing the bearings out of the way so it can realy wing the rod out the side of the case

now just go ride the shit out of it....

Thanks for the reassurrance, pig!


Riding the shit out of it, hell yeah. I am planning a trip to the sand dunes on april 1st to tear it up. That is if the snow melts by then.

go put it thru the ringer man beat on it
