A couple of weeks ago, I bought a s-maxx 3.3 from a guy who said it needed a piston and sleeve, I ended up swapping the piston out from my old trx 3.3 parts motor and used the new sleeve. So basically I just swapped the sleeve out to make a running motor. My question is about break in. What would you guys reccommend for a sleeve swap? Do I have to go through the entire traxxas break in procedure???
P.S. I have idled 1 tank through it, but it requires a lot of idle for it to stay running, what are my options there???
