why is it that people want to be cheap in this game? you find motor on cl forsale 650 with 45k miles on it you will buy it cause it looks clean head looks clean but yeah now when you install it your on the forum asking question why am i smoking, i hear a knock 3k rpm, my vvl not kickin in. For some piece of mind ill wait an extra month and get my motor from andreas cause if somethings goes wrong i can deal with him. when you buy a motor of cl your screwed. Never try to save money it will cause you in the long run
