BAMF87 Posted November 2, 2013 Report Share Posted November 2, 2013 Guys just went to the dunes with some friends, both have 450r,s one is ported and cam bigger piston and dasa, other is same without the porting. Well when dragging the ported one would get me by half a bike if I didn't shift absolutely perfect. He had straight 8 paddles. My bike has a frest top end with HjR dune port, +4 timing, stock crank, chariot reeds, fmf fattys, 28mm pwk's, 13/41 gearing with crappy v paddles. I know I need to change sprockets and get better paddles but I thought I would be pulling harder on him. I rode the ported 450r and it hooks up and pulls hard as fuck Quote Link to comment Share on other sites More sharing options...

Coupelx Posted November 2, 2013 Report Share Posted November 2, 2013 Also put some fuckin tires on it. Quote Link to comment Share on other sites More sharing options...
hercalmighty Posted November 2, 2013 Report Share Posted November 2, 2013 Some cpi or shearers would make a difference. I havent riden in sand before so I dont know about gearing for sand but I had no problem pulling a 15 tooth front with a pretty much stock bbike : Quote Link to comment Share on other sites More sharing options...
Pasi S. Posted November 2, 2013 Report Share Posted November 2, 2013 In my opinion (not a Banshee expert), your gearing is off like you said. With your pipes, you should make enough power to take that 450 down a little easyer. I have 20x11 v-paddle tires on 10" black labels and I have power around 65. I can turn them easy with 14-41 and 15-42. You should do the same. (just my opinion) Quote Link to comment Share on other sites More sharing options...
BAMF87 Posted November 2, 2013 Author Report Share Posted November 2, 2013 Ok thanks Kevin at hjr said I would gain at least 5 hp with shearers so I'm sure it's ported for those pipes. As soon as I get funds I'll get pipes an tires. Maybe Santa will be nice this year. Quote Link to comment Share on other sites More sharing options...
camatv Posted November 2, 2013 Report Share Posted November 2, 2013 ANY "ported half ass motor is going to gain at LEAST 5 hp from going to most any drag pipe over most any "trail pipe" hell i have seen 10hp over fmf to shear just because of the added RPM the shear will support.. its a pipe action thing. most trail pipes run in a lower rpm range. they are made that way to make them more fun in trail riding.. drag pipes are just that drag pipes high rev pipes. most start at about 7500rpm and support up to and over 11,000 rpm's...... then there is the welp its ported for trails. bla bla bla i rember matt posting up a lil 350 that he did with lower than most exhaust numbers ( 191 duration not sure if thats what it really was or what) but that lil motor made a lot of power overall. nice gradual curve on the dyno graph he posted. hell most "trail" ports i have seen were pathetic clean ups and resulted in a 192 to 195 duration exhaust.. so hmm the hjr port should be fine yes the gearing blows.. i really dont understand why anyone runs a 13 tooth on the front. and even worse i have seen some 13/45 bikes and 14/45 bikes out there "shitty V paddles " welp you said it right there. now after you get some real tires the bike is going to want to wheelie like a mad man and then you will have to chop the throttle a lot unless the sand is very very dry. so then there goes the 4 strokes... and at least around here they 4 choke crowd races all of about 200ft. bla other thing i see ALL the time is horrible setup everywhere else. bad ignition, crappy fuel, ( what you mean its bad its been in an open container in the sun for 9 months?) crappy built chassis work, bad flywheel, bad overall tune up on the entire bike.. i'm not saying this is your particula situation but i see things like this a LOT.

BAMF87 Posted November 2, 2013 Author Report Share Posted November 2, 2013 Well guess I know what needs to be done now thanks for the input guys. Quote Link to comment Share on other sites More sharing options...
BAMF87 Posted November 2, 2013 Author Report Share Posted November 2, 2013 These are the paddles I have. Sand sharks I believe. These came with the bike along with the sprockets that were on it. It was set up for trails Sent from my iPhone using Tapatalk - now Free Quote Link to comment Share on other sites More sharing options...
sprinklerman Posted November 2, 2013 Report Share Posted November 2, 2013 Get haulers and sand blast the 450. Quote Link to comment Share on other sites More sharing options...
Pasi S. Posted November 2, 2013 Report Share Posted November 2, 2013 I have the same Sand Sharks. They work OK for me when I do some hill climbing on a rough sand. Better than knobby tires. Quote Link to comment Share on other sites More sharing options...
quadgod211 Posted November 3, 2013 Report Share Posted November 3, 2013 to me it wouldnt be worth the costs for new paddles unless you were just setting there spinning... pipes would help the most ....14 or 15 launch in 2nd a ported 450r with a dasa and big cam no airbox will make 60hp and put most of it to the ground especially in a trail type environment Quote Link to comment Share on other sites More sharing options...
Coupelx Posted November 3, 2013 Report Share Posted November 3, 2013 60hp? Slowest 60hp ive ever seen. Quote Link to comment Share on other sites More sharing options...
RagunCajun Posted November 3, 2013 Report Share Posted November 3, 2013 and at least around here they 4 choke crowd races all of about 200ft. bla They run out of steam in 4th and 5th? I find they do with the mild drag 450's ive ran. OP if your bike is fun, id leave it alone. You add more power, different tires etc and you will probably do better. But what happens when they get faster or someone else is. That's how drag bikes form. You have a VERY clean bike. Id threw some at least some CPI's if not some shearers just because i liked how they work for open runs. I went from t6's to t5's to CPIs. It was crazy to see the top end difference with CPI.

BAMF87 Posted November 3, 2013 Author Report Share Posted November 3, 2013 Thanks I plan on cpi pipes because they aren't that expensive and have midrange power. The 450r made 53 hp on the dyno at racersedgeaz. I'll try and get my setup working good and after they upgrade more I'll go 4mil. Until then I'm happy. They spent way more money on their motors than I did so I'm happy to still win Sent from my iPhone using Tapatalk - now Free Quote Link to comment Share on other sites More sharing options...
