Well as some of you might remember I ended up getting my girlfriend a Suzuki LTZ400. We got a good deal on it and put another $100 into it. She likes the bike but really just likes the ergo of my 07 YFZ better. So.....I set out on a mission to find a good deal on her one. Found a guy that has a 06 that looks to be in nice shape, looking at pics so far. He bought it from a friend that bought it new and put a big bore kit on it/stage blah blah cams, etc and spent quite a bit of money. This guy got it and pulled the big bore kit and cams out but but left the rod (said he wanted a stock bike) He put a used jug on it, new piston/rings and put it back together then saw he left out the timing chain guide so pulled it back down. When he put it back together he rode it 2 hours and HG let go (he said it still will run but whistles). Figured this happened because he torqued the gasket then tore it back down and then put it back together. Anyway he wants to trade me straight up for the LTZ400. The YFZ also needs a starter. Ive got less than $1000 in the LTZ should I swap him? I hate buying things where people have been inside the motor....what should I look for? Im always worried when people mess with cranks/rods/pistons and change it that they got the wrong combo back in there and well you know what happens. Sorry so long just dont want to make a dumb choice and my gf be out a bike!
