The easiest way to get big gains is with a tuned pipe. It will increase your low and mid range torque.

Your top speed, stock should be between 25 and 35 mph.

also i took off the cover to the flywheel and greased the gears and put some rubber in there to quiet it a lil, i noticed there is what looks to be clutch material, is that normal after a week of running? i am really interested in mods!! mainly right now things i can do by myself without spending to much money at this time. i seen some one said they run without head gaskets, does thta work witout leaking.

hey mate.
Iv never heard bout anyone not running with head gaskets but i would highly NOT reccoment it. i reccon that it would leak a bit. the "clutch" material that u talk about might just be wat was left in there from factory, the same thing happed on my bike.

Im not to sure on cheap mods apart from what easy rider said, a tuned exhaust is a good one. I havent had any need to modify mine anymore, it goes quick enough for me.

Good luck with ur bike. ( have u got any pics)

Intake and exhaust manifolds would be my first mod along with new gaskets, plug and plug wire next, then pipe.

You just twist it out counter clock wise and clock wise to install the new one, there is just a screw in there.

does a copper core wire have to be used? can i use a automotive wire?

There is no metal in automotive wire, try a tractor supply or a small engine shop, they will have a roll and can cut you a length. Or you can can one with one end attached. I think you want 7 or 8 mil but you may want to verify that.
I also used a hot glue gun to put a nice seal around it and never had a problem in the rain after that.
