dco3100 Posted July 28, 2009 Report Posted July 28, 2009 Finally getting close to getting this damn thing on the map :beer: Narrowed it down to 4, 14/15 paddle rippers 22"/73 roll out or 16/18 paddle staggerd extremes 24"/78 roll out. I cant go out and buy all 4 to see what works best so I need you guys on this one! never had something with so much power so im really in the dark here. Just for the record, this DM is going to have a 10mil stroke with a 78mm bore = lots of torque, as ive been told. Also, just for the record, I seen vids of a 4mil running 16pdl staggard extremes 78roll out , launching out the hole like a mad man and whoopin up on everything with 13/43 gearing. I thought I knew a lil something about paddles but I guess I need a bit more research, thus this topic.... I need you guys for this one! Quote
shanYE west Posted July 28, 2009 Report Posted July 28, 2009 Can't give you suggestions if we dont know anything about chassis setup, type of riding, what type of surfaces, gearing that will be used, Primary ratio's and other odds and ends of info that is being left out. Quote

FireHead Posted July 28, 2009 Report Posted July 28, 2009 wheelie bar or no? If you are not on a bar, I would suggest the staggered tires. I ran a generally similar setup on my old 10mil (potentially a little more power), and the only way the 14 paddle Rippers I had would do their thing was on the bar. The 16 paddle SLS staggered tires were the weapon of choice for hill shooting without a bar. I would suggest a longer swingarm if you are not running a bar. I thought I knew better when some folks suggested otherwise, but it turns out that I did not. Quote
shanYE west Posted July 28, 2009 Report Posted July 28, 2009 My opinion would be 14 extremes for no bar.. and 16 extremes with a bar. He left out that this motor would be run on gas.. Quote

As for the 14 extremes, if that lil 4 mil can hook them 16 staggards with an 81 roll out with no wheelie bar , then 14s arent even in the picture Quote
shanYE west Posted July 28, 2009 Report Posted July 28, 2009 You said it was on Gas last time. http://www.bansheehq.com/forums/index.php?...=116692&hl= You are probably talking about Ray's 4mil with the 16 stagerds... I wouldn't use that as a guidline. He'll be the first to tell you that every track is different.. What works at one track might not work at another. He brought that bike to our tracks here and it was WAY too much paddle. He turned faster times with 14's, and probably would have turned better times with 12 or 13's. I still say 14 or 16 extremes will be plenty.. if you want rippers.. maybe a 12 ripper. Since your not running a bar and its in a stock chassis.. stay away from the more agressive tires. my 4mil with 13 extremes and a +12 arm was always reachin for the sky.. What you think a DM is gonna do with a similar chassis setup with ALOT more tire?? Quote

As for the 14 extremes, if that lil 4 mil can hook them 16 staggards with an 81 roll out with no wheelie bar , then 14s arent even in the picture I, too have seen little motors pull ridiculous tires, but those are an anomaly (sp?). ...and gearing and swingarm length have a lot to do with it. I have seen 10 mil DMs on ridgid chassis' with a bar run 14 staggereds, and run 3.6-3.7s. I ran 14 staggereds on both my 14 mil and on my 4mil, and loved them on both. I tried to run some 16 pdl staggered rippers 82 r/o on the stretched ridgid stock chassis in sig, and it twisted the swingarm/chassis/something and wouldn't go straight down the track. I hooked HARD with a 1.35 60 ft, but I'd have to let out of the gas a couple times in the middle of the track to keep from hitting the guard rail. I still have the staggered rippers if anyone wants to make an offer. Quote
No Limit Powersports Posted July 28, 2009 Report Posted July 28, 2009 We have found the more torquey motors like the rippers better. But keep in mind that ro plays a big roll in how a tire will bite. You will find that a 72" tire with 13 paddles will hook about the same as one with 15 - 16 paddles there just starts to get to much flotation on the tire and the blades are not scooping any sand. But the same 15-16 blades on a 80"+ tire will have more "effective" scoops per axle rotation. IMHO i think that motor will pull a 14 paddle ripper in around a 78-80 if the chassis is there to support it and a bar might be a handful without a bar lol! Quote

And a 16pdl Staggard Ripper 82roll out I couldnt imagine what that tire looked like... We have found the more torquey motors like the rippers better.

Some damn good info here, that sounds really good, im leaning towards the 14pdl ripper straight blade 78roll out?? NEVER CAN HAVE TOO MANY OPINIONS, keep em comin fellas! :biggrin: Quote

NEVER CAN HAVE TOO MANY OPINIONS, keep em comin fellas! :biggrin: 14 mil is a Cheetah (593 cc) 4 mil is Cub. Tire is extreme. BTW I run 14 extremes, 84r/o on my 16Mil Cheetah. Haven't gotten a good pass down the track yet due to several issues, but it has run a 1.38 60 ft. The 16 mil Cheetah is roughly the same displacement as your DM at 610 or 611 cc. Not to say that the power output is identical. Quote

He would know what tires works best with his setups.. Just outa curiosity.. who's doing the portwork? Quote

Not to say that the power output is identical. yea, i would think the bigger bore 78mil would put out more torque, whereas the longer stroke motor would put out a bit more horses. I wouldnt want a tire quite that big (84 roll out) As for where im buying everything and doing the portwork, its probably going to be Andy from M&M, seems like a real nice guy with ok prices, ive talked to many of the big names and they all are ok but you can tell that Andy puts out that EXTRA effort to get what you need and take care of you. soooo :geek: Quote
