I say you don't know what you're talking about.... The valve adjustments you're talking about are actually cam timing adjustments, and they usually don't add power to the motor unless they were off from the factory, they move the powerband. Sprints are all about torque coming off the corner, so you need to get it dialed in. "Rebuilds" is a very general term, it depends on how much is being done to the engine. Every watch a micro race? They run about 14k rpm the entire lap, they never lift. Alky isn't an option, you either run it, or park it, because it's too much of an advantage. Ever seen the inside of a alky motor? Alky is very corrosive, it eats everything, so you have to rebuild those motors at least once a year if not more. CR
[EMAIL PROTECTED] wrote: Did some research on 600cc maintenance cost. 600cc midget racing here in Pa/DE/NJ is big. Kaw, Yam, and Hon engines stock engines/clutch/cab'd or FI, open air intake and exhaust. Fuel is optional gas or alky. 1. Stock rebuilds range from $1200 to $1750 depending on how many new parts are needed. 2. Pipes around $460 w/muffler for 95 db track rules. 3. Appears as if older (?) Kaw motors are easy to find and less expensive. New motors are faster (better factory porting) harder to find find and much more costly. 4. Apparently dyno generated valve adjustments settings are a big tuning component. Cost is approx $500 just to have this done with no dyno time! After seeing these prices I quite looking for prices on clutch rebuilds. I suspect a 600cc car will cost considerably more to build with a new/used (?) engine and cost more to race. OK Chris R, what say you? Louie Schultz Philly Region PS Noticed other interesting facts. Huge fields. Four car maker in PA alone. A complete 600cc midget with options is priced much lower then new F500 cars ie big market. Also Linda's Speedway, somewhere around Harrisburg, runs a $10K to win race for this class...yea baby! --------------------------------- Don't be flakey. Get Yahoo!
