I have been looking for a 400ex engine or a mid 80s yz250 engine and finding killer deals but nothing in my try-state near IN ther is a 400ex on ebay right now it's stock and used for $300 but it would b nice to b able to deal face to face if I could without driving over 300 miles

I live in Indianapolis looking to bye with cash and my quad is a 2003 400ex I would like to put the right engine on it but I put in the part about the mid 80s 1983 - 1985 250 yz 250 or 1998 cr 250 because I have a few top-ends that have been ported for alcohol and used on a micro-sprint I used to race I would need a good bottom-end because the clutch was cut off and flywheel was welded and the kick start removed for use in the micro-sprint I was thinking of maybe building a 250 2 stroke and retrofitting it on there Its close in power to weight ratio and I thank it might fit I have over 10 years of part fabrication

getting the exhaust pipe to fit right might b tricky but engine mounts are easy

I looked on eBay there are a few up for grabs anywhere from $399 to $900.  Is the old engine completely gone ? Can’t rebuild ? 

I looked on there and they are mostly like 900. If u see one for 500 or less let send me url. Yes I got old engine but I think it's cheaper to get new one. Pistons came out the side of trans case
