You're going to have to be more specific. To make your bike a 686 all you need is a new piston and the gaskets to put the engine back together. A simple bore and hone and you're all set.

Now if you want some real power out of it you can spend a lot more money. New cam, valves, valve springs, carbs, intake, filters, exhaust, porting, etc. Craycraft, kenz, and other builders have 686 "kits" that will change out a few of these parts as a baseline and you can go from there. You can buy 686 "kits" on ebay that include just the piston and gaskets or piston/gaskets/camshaft/springs.

For reliability's sake I'd suggest making sure you have a stronger connecting rod and the 02 trans update. You'll need to regear to get the most out of the power and a new swingarm and possibly tires will help you get the power to ground more efficiently.

alright well thanks for the info i guess i didnt look into it as much as i should have. i already have a decent set of tires that im real happy with right now. and when u say regear what is it that u mean. like the front and rear sprocket? if so i have that geared down already. i can prolly do more with it but for the kind of riding i do the set up that is on it now seems to work just fine for me.

You must've gotten raped. I'll bet for the price you paid you could have sent it out to a builder.
