So why, if you are gonna spend the money to have the stock head redone, would you then run out and buy a coolhead (and craptastic orings)? pick one and be done.
I dont understand why everything needs to be so complicated with newbies.
having a stock head done up is less than $100. The more i research and play with my setup the more i learned that dome design is critical for a proper setup. the one mull engineering did for me made all the difference in the world. the bike has loads more power off the pipe and a very nice transition. i rode trails for about an hour just cruising off the pipe with the powerband just a blip of the throttle away.
you can get one from the auto parts store for less than $10. Same as used on honda cars. Its a bit higher pressure though but if anything it will help keep it from boiling over as quick.
check the center bearings and rod bearings for slop and make sure the thrust washers are in good shape. replace the outers with maxloads and have it welded. profit.

cylinders and sometimes the top of the radiator will get hot but the bottom of the radiator will never warm up.
I personally see no need for anything other than a new stock impeller. the gear is iffy. Ive never had a problem but some have. If the bike is over heating you need to look at your setup, jetting or riding style.
mine sits next to the shop for easy access for a brap. or in the barn or whatever depending on the weather. People dont steal shit out here, the ones that do were probably shot long ago.
