sprinklerman Posted June 24, 2012 Report Share Posted June 24, 2012 Need some pointers in the right direction as to adding some bite to my setup. It is as follows: Soft powdery Sand 4mm Serval (ported) dyno'd @ approx 85-ish HP/45TQ (pump gas) + 6" swingarm set level/slightly up in the back 14/41 gearing stock frame 9 paddle Padla Brats 21x12x8 Comp cut rider 200# Problem is im blowing off the tires thru 3rd gear,just getting good bite into 4th,but by then you are almost done. Need to improve the 1st 60' for sure. Getting tired of reeling people in. any suggestions? I have play tires ,so these can be strictly for drags.

sprinklerman Posted June 24, 2012 Author Report Share Posted June 24, 2012 Thanks for the reply. whats the advantage of those over a say 21x12x8? Let me describe as best i can a typical race. I have to feather out 2nd gear launches , not because itl bog,but because it'll spin the tires so quickly that 3rd gear shift is almost immediate. Then 3rd gear,the tires are trying to hook a little,but still blowing off pretty bad. Click into 4th and they start to bite and it really starts gaining ground quick...but by then you are about ready to shut it down. I have a 15t front sprocket im going to try asap,but i really dont think thats the real solution.... any thoughts? Quote Link to comment Share on other sites More sharing options...
possum Posted June 24, 2012 Report Share Posted June 24, 2012 16-41 12 paddle 22" /done! Quote Link to comment Share on other sites More sharing options...
sprinklerman Posted June 25, 2012 Author Report Share Posted June 25, 2012 16-41 12 paddle 22" /done! Im thinking that might be a little too much for a pump gas motor, yea? Quote Link to comment Share on other sites More sharing options...
Surfrjag Posted June 25, 2012 Report Share Posted June 25, 2012 from what i understand those brats arent that great off the line so like mentioned you may want to look into something along the lines of the skat trak exteme's. as far as gearing i like to gear lower than most so you may consider gearing lower to get out of the hole in 2nd. im guessing your only going 300ft?

Yea, 300'. Problem with gearing lower is im already spinning like crazy launching in 2nd. I can actually launch in 3rd sometimes as it is. So im pretty sure more paddle is needed. Im wondering what difference there is in grip between 21x12's and 22x11's. and i need to narrow down if i need 10 or 11 paddle tires... thanks for all input so far.

Surfrjag Posted June 25, 2012 Report Share Posted June 25, 2012 your blowin your current tires off. but try some 12 paddles stag extreme's and i bet you wont blow them off as bad. guy running a stock cyl 4mil at my track is running 14paddles 22" Quote Link to comment Share on other sites More sharing options...
nastyracing Posted June 25, 2012 Report Share Posted June 25, 2012 A brat is all u will ever need in my imo . Take a tire sipe to the base of paddles if yours arent already cut that far. Most importantly make sure u have a 15t up front 5 psi is key on them tires. What u have now will be pretty equal to a 10paddle extreme. Try gearing first tho Quote Link to comment Share on other sites More sharing options...
Surfrjag Posted June 25, 2012 Report Share Posted June 25, 2012 I agree with trying gearing first but there is a reason why all the fast bikes run extremes or rippers. They have more bite. Quote Link to comment Share on other sites More sharing options...
nastyracing Posted June 25, 2012 Report Share Posted June 25, 2012 Give or take kinda thing 300ft is a short race . But a bigger front sprocket is gonna be like a whole new tire to him. Quote Link to comment Share on other sites More sharing options...
dcalsv02 Posted June 25, 2012 Report Share Posted June 25, 2012 I'm running 22x11x8 10 paddle, extreme, 74r.o super lights. I would recommend those in 10,11 (if they have them), or 12 paddles. Quote Link to comment Share on other sites More sharing options...
camatv Posted June 25, 2012 Report Share Posted June 25, 2012 brats totally suck off the line unless you have let them down to about 1 psi and sit on the grab bar. they work good for shorty swingarm bike. to stockish bikes too ANY scat track tire in the 9-8 " 9 hauler to 11 exxtreme is going to make a huge difference in your "bite" off the line. but just rember got too much and your going to fight wheelies Quote Link to comment Share on other sites More sharing options...

I called Fullerton Tire and they recommended 22x11x8 extremes with 11-12 paddles. going to see if any banshees show up at our riding spot this weekend and talk to the faster guys,,,,if anything but four stroke show up.

RadarRacing Posted June 27, 2012 Report Share Posted June 27, 2012 If your bike sits high in the back that will suck with those tires. Get one of the $30 billet lowering blocks and get your grabbar about 5" lower and it will help a ton. With about that power and a +6 my old gas bike liked 21x12x8 9 or 10 paddle extremes. If you are lighter than 200 lbs go with a 10 extreme in either a 21 or 22. They are both real close to the same size but the 21" is lighter. If you meet up with us sometime I can come up with about every tire to try. Quote Link to comment Share on other sites More sharing options...
