Guest JohnTabata Posted December 5, 2013 Report Share Posted December 5, 2013 Not exactly what i meant. i was assuming people had a good chassis setup with proper weight transfer, tires, clutching etc. my thought was dollar for dollar for dollar youd be better off building more power and focusing on getting it to the ground. eventually these bikes get heavier as the power comes up due to engine weight,extra wheel base and chassis stiffning. in your example of the light bike vs big bike i would think track would be the smaller lighter bike but on big hills the fat guy with more power would be the favorite. I'd chose whatever is faster. Small motor, big motor, lighter, heavier... fast is fast. 1 Quote Link to comment Share on other sites More sharing options...
fastkid Posted December 5, 2013 Author Report Share Posted December 5, 2013 Well if menz can run a 3.58 on a 421, without a jockey (yes he ran this on his own bike too) then this is a very valid and important discussion we're having at getting faster. Fast is fast, and that 421 is running with large twins, and it's mainly due to power to weight. What have people done on the inside of the motor to lighten?! Any adverse effects on performance running light internals? Quote Link to comment Share on other sites More sharing options...
m671054 Posted December 5, 2013 Report Share Posted December 5, 2013 The menz 421 is far from something people on here can buy. he is a very sharp individual and has spent the time to fine tune every aspect of it.if you dont build motors and spend countless hours dyno testing then that small engine is not a good comparison.

m671054 Posted December 5, 2013 Report Share Posted December 5, 2013 Gonna leave it at this, smaller engines are very efficient. from a 421cc bike up to a 817 your only gonna gain 50-60 hp. Bigger guys need more power or less weight to be competitive. i feel its cheaper and safer to go with more power vs light weight parts. if your 140lbs go with a small mtr lightish bike youll be fine. but 200+ youll need more tq plain and simple.

fastkid Posted December 6, 2013 Author Report Share Posted December 6, 2013 I've read SAE papers that have shown power increases on kart engines from cryo'n the when thing. Off topic but interesting Quote Link to comment Share on other sites More sharing options...

Coupelx Posted December 6, 2013 Report Share Posted December 6, 2013 Ive heard girls cant get preggers if they are on top when you blast them with baby batter. Quote Link to comment Share on other sites More sharing options...
fastkid Posted December 6, 2013 Author Report Share Posted December 6, 2013 Much smarter men have took the time to do the testing and publish a paper about this shit. They don't try and sell a product, they publish results and science.... Back to the topic though, anyone know the cub vs wampus weight? Wampus casting is definitely lighter but is it significant?

fastkid Posted December 7, 2013 Author Report Share Posted December 7, 2013 Anyone know the best lightweight batteries available for using an msd? I remember seeing a company a few years back that had ones that were around 15 ounces, but I don't remember the name. Any quality lightweight batteries out I could use for a msd ignition?

joshb Posted December 7, 2013 Report Share Posted December 7, 2013 The ballistic batteries can be small but I've seen drill batteries as well. Quote Link to comment Share on other sites More sharing options...
RadarRacing Posted December 7, 2013 Report Share Posted December 7, 2013 Ballistic if you want lightweight and small. They feel like they are empty. Quote Link to comment Share on other sites More sharing options...
