harley_sr Posted August 10, 2004 Report Share Posted August 10, 2004 Ok I am setting my banshee up to run at the local drag strip 1/8th mile. I am woundering about some pipes. What will be better for me? A set of Rocket InFrame Pipes, or a set of Trinity Out of Frame drag pipes. The guy siad that they were better for 350-420 motors.. Is he full of BS or not. I really like the look of the out of frame pipes. The bike will never see the trails again, its strictly drag. But I do not have a heavly modded motor. I am running: Noss Head 20cc Domes V-Force 2 Reeds 30mm D-Slide carbs K&N Clamp on Filters Going to be .60 over pistons Boost Bottle was alredy on bike 6in Swing arm and some other mods, but not to motor. So will I be better with Rocket inframe pipes, or Trinity Out of Frame Drag pipes? Quote Link to comment Share on other sites More sharing options...

harley_sr Posted August 10, 2004 Author Report Share Posted August 10, 2004 will they kill my bottom end? I only ave the 1/8th to make my run.. Quote Link to comment Share on other sites More sharing options...
Cotton eyed Joe Posted August 10, 2004 Report Share Posted August 10, 2004 will they kill my bottom end? I only ave the 1/8th to make my run.. I'm with Oilsmoke on this one. The out of frame will basically facillitate getting the exhaust gasses out of there as quickly as possible with less bends, as are common with the in frame pipes. On the bottom end issue.....you can't have it all unfortunately. One thing you can do is mess your gearing. You can gear a little lower, or get a lock up on the clutch, and just give it hell. An over ride tranny would also be wise. You won't have to touch your clutch but twice. Once to launch and once when ever you let off the gas. An 1/8 mile is still 660 feet. Thats still a distance to travel. Get up on the pipe, in the top rpms and you won't have time to worry about bottom end. Quote Link to comment Share on other sites More sharing options...
harley_sr Posted August 10, 2004 Author Report Share Posted August 10, 2004 dont mean to sound ignorant, but what is a override tranny? Please explain? I got the trinity out of frame drag pipes on ebay for $290. Is that a good deal? Also on the tranny where to get it, and how much? Quote Link to comment Share on other sites More sharing options...

An over ride tranny is a modification to your stock transmission that allows you to shift without pulling in the clutch. The drive dogs are ramped and the shift drums are relieved to allow you to shift into the next gear, which causes the countershaft to spin faster, the ramps on the first gear are now going towards each other, they ramp out and the notch in the shift drum allows the fork to slide to the side. If you let off the gas with out pulling in the clutch, the ramps push the gears apart, (since now the pressure is coming from the rear wheels to the engine, instead of the engine to the wheels...to simplify things a bit I hope) but since you haven't selected a gear that has a relieved notch in a shift drum, it will bend your shift fork. A small price to pay for shifts that only take about 1/4 of a second. On the tranny, I'm sure any of the reputable builders can cut them for you. K&T, GrandRiver, etc. Not too sure on the price. I don't have mine done as I'm not into the drag racing yet. I will be eventually, but right now I prefer to dune. Quote Link to comment Share on other sites More sharing options...
nater006 Posted August 10, 2004 Report Share Posted August 10, 2004 $290 doesn't seem too bad for those. They're like $440+ on Trinity's site, and the low end price is for unfinished pipes. It'd be a good place to start, anyhow! Quote Link to comment Share on other sites More sharing options...
