·I have a 900ssie that I'm swapping the pistons and having the heads worked on a little bit, and I'm really apprehensive about the best way to run it in when it's all back together. I did a search but couldn't find anything about breaking in a "used" motor, only discussions on new engine break-in.
I'm worried that I won't be able to seat the rings properly and will ruin my motor the first time I ride it. I didn't have the cylinders honed because I was under the impression that you didn't need to (or actually are unable to) hone the nikasil cylinders due to their hardness. Hell, they look absolutely brand new to me.
Should I try to break it in on a dyno, or will a country road suffice? I don't know how expensive it will be to do it on a dyno, and I don't know if I can afford it, so I'm hoping the backroads will be good enough.
Any tips or advice for piston and cylinder reassembly are also very welcome in addition to advice for the break-in. I guess I'm just paranoid that something will go horribly wrong and I'm afraid of turning my motor into an incredibly expensive paperweight
Oh, one last question, when I took it all apart, the tops of the pistons and the combustion chambers in the heads were caked with carbon buildup. I know that's not normal, but I had no oil consumption before I pulled the motor and I've always used good gas, so I'm wondering what the cause is. Running too rich maybe? Anyways, thanks for the advice!
