i have a 88 tecate 4 and was wondering how hard it would be to put on a gauge cluster from a road bike or something and if its posible and how hard would it be to replace the engine with a kx 500 engine would it be just a bolt in project or what if any of you have info that would help alot if there is an easier engine too put in it that could beat my friends yzf 450 and my other friends raptor 660 thanks
