damn, it sold that day before i could even look at it. saw another smoker, GT550 for $1500. all stock and looks even better then the titan.
i only have messed with small 2 stroke engines but i know there's not much to an engine rebuild: rings, bearings, and reeds.
bearings i can usually spec and get some through a bearing supplier. rings i can usually have made if not available. before the CB750 F2 became popular, I had a manufacturer make the correct spec rings for the pistons and it only cost about $150 for all 4. it just comes down to the reeds.
suzuki seems to be the bastard of all the two stroke street bikes. not much can be had through a lot of these suppliers.
