kawiking Posted April 11, 2009 Report Posted April 11, 2009 Wth is that? Thing looks like a Praying Mantis all jacked up that high. jk lol maybe .... but it has f.a.s.t. on the motor... lol Quote
BoostedRex Posted April 12, 2009 Report Posted April 12, 2009 I should have mine under 200 lbs pretty easy, I'm actually thinking it will be closer to 180 when I get it all done. Quote
bada450r Posted April 12, 2009 Report Posted April 12, 2009 I should have mine under 200 lbs pretty easy, I'm actually thinking it will be closer to 180 when I get it all done. i think even the TI chassys weight at oround 200 so if you get your bike to weight under 200 let me know what the secrect is Quote
shanYE west Posted April 12, 2009 Report Posted April 12, 2009 i think even the TI chassys weight at oround 200 so if you get your bike to weight under 200 let me know what the secrect is Thats what I was thinking! Quote
bada450r Posted April 12, 2009 Report Posted April 12, 2009 Thats what I was thinking! i call it BS 180 please.........i mean it could probably be done but not out of any type of metal........it would have to be carbon fiber like those light ass bicycles...... Quote

Or.. it might not be built strong enough and will twist up like a pretzel. Quote
BoostedRex Posted April 12, 2009 Report Posted April 12, 2009 Or.. it might not be built strong enough and will twist up like a pretzel. I'm hoping it dont twist like a pretzel... lol The frame I have is all aluminum and so are the a-arms and steering stem. I can pick up the bare frame with one hand and place it over my head . It has been used for 300ft drags and never had a problem. But it has never seen some mean whoops on sand so I'm hoping it can take the abuse. But my rolling chassis weighed in at 83 lbs. That was with dirt tires and spindles on the front. So i figure my spindle mounts will drop around 10 lbs off of that. So unless the motor, carbs, pipes and chain weigh over 130 lbs i'll be under 200. Quote
trex banshee Posted April 12, 2009 Report Posted April 12, 2009 290 as you see it below. Thats ready to run. No bar though Quote
dajogejr Posted April 12, 2009 Report Posted April 12, 2009 I've got every light weight part available and mine is a Jarm chassis on top of that. I think mine race ready is 260 to 280, but once I button it back up, I'm gonna weigh her so I know how much weight I'm saving when i get my new frame. Gotta weigh it with the wheelie bar, too...of course. All aluminum frame? Good luck on that....better get Geico....and Aflack. Quote
shanYE west Posted April 12, 2009 Report Posted April 12, 2009 All aluminum will twist and bend from the torque. It takes twice as much aluminum to match the strength of moly. So the weight savings would be minimal if any.. If the chassis was built correctly.. I saw one on ebay awhile back. No way I would run that.. its just a accident waiting to happen. It will fail... its just a matter of time. Lets just hope your not doing 70+ when somthing decides to go. Quote
Stellar Performance Posted April 12, 2009 Report Posted April 12, 2009 Yeah...I hate to break it to you. But if the aluminum chassis was built with any common sense, it would only weigh a matter of a few pounds less than a chromoly one. On average it takes at least, but usually more than twice the wall thickness of 4130 to be able to build a strong enough chassis, not to mention even more bracing. As far as aluminum arms go, same thing. I can hold any one of my chromoly drag chassis over my head with no problems at all as well. I'm not trying to sound like an ass, so please dont read this wrong. But some where your math is not adding up. Most banshee motors weigh in right around 80 pounds. Most full chromoly hillshooter chassis weigh in around 30-35 pounds. Then start adding arms, shocks/struts, swingarm, chain, axle, wheels/tire, brakes, pipes, carbs, radiator, hoses, electrical, stem, bars, spindles, bolts, nuts, etc, etc.......it adds up really quick. Next thing you know you are still up to 250 or so. Quote
rubberneck Posted April 12, 2009 Report Posted April 12, 2009 So what you guys are all saying is if i want to drop some serious weight off my drag build, the best way is to give up cheesburgers and fries. damn. maybe ill just build a bigger motor, that sounds easier. :biggrin: Quote

Just not cheaper. Hahaha. Quote

rubberneck Posted April 12, 2009 Report Posted April 12, 2009 Good Idea Justin... I might have to try that one!! lol From the looks of those cr500 reeds in your other post I would say you are building a plenty big motor already :thumbsup: Quote
