Need help! 250r rebuild questions.
Ok guys, need some motor heads help. Gettin' ready to rebuild the R's motor and can't decide how I want to build it. A guy at the local shop told me to use a 87-89 crank and rod with a 86 piston and a spacer plate to get more mid-range and top-end. I started to order the stuff to do it, but have seen a couple of people that said it will be slower. Should I go for this combo or stick to a stock or overbore application. Any help would be appreciated!
