hey im new to the site and i just wanted some advice from people that knows these trikes, i just bought a 1985 tecate 3 off of a guy for 150 bucks and he said it would need a sator and flywheel but i would like to puet a kx 500 engine on it instead, would it be a tough job to tackle or would it be worth it i want to drag it at the local drag track this summer thanks mike
