We initially used the ignition kill in conjuction with the air shifter. We could only get the air shifter to work around 97 percent of the time. The 3 percent it didn't work, seemed like it always cost us a round win. We took off the air shifter and do it manually now. For the 5 & 6 shift we hit a button and the shift lever at the same time. The button is wired into the Dyna shifter counter/ignition kill. As for secrets, I will point you in the right direction. The same as many people did with me over 30 plus years. We have made about 600 runs on our quad in the past 4 years, but most of the know how came from drag racing cars over the many years. Bryan

We use a ignition kill for 5 & 6. It allows for clutchless full throttle shifts.

1-4 override, manual 5 & 6.

Nice try! Now based on your previous info in this post. I keyed on lugging in 6th gear and your 17/39 (2.29 ratio) sprockets. You would be going the wrong way with 2-1 ratio. The key is to have your peak RPM higher at the end of the 1/4 than your peak HP RPM. How much over and how you determine that is up to you. Hint, your MPH will tell you if you are going in the right direction with your gear changes. The lugging you describe could also be that your main jets or power jets are not correct. Bryan

We effectively used any where from a 2.05 - 2.24 ratio and have found one good all around ratio that works on different combos.

IMO the gearing is not right for the 1/4 mile if you only using 5th thru the 1/4. Now for the 1/8 mile it's a little different.

You will be surprised on how to gear a quad for the 1/4 mile. There are very few people that run the 1/4 with a quad. Our quad is in 6th gear before the 1/8 and you wouldn't believe how many feet before. I don't need to BS, our times and MPH speak for themselves.

I forgot to say our rollout on our tires is 73"s and it's measured around the circumference of the tire.

I'm new to the sand and the two times I've made it out; 1st to Glamis and 2nd time to Dumont. The 1st time out I ran 14 paddle 22x11x8 haulers that were borrowed from a friend. The 2nd time out I bought a set of 12 paddle 22x11x8 extremes. I think I like the haulers the best. Our quad is normally on asphalt, but we are having some fun on the sand. You can find our sand videos in the drag forum under asphalt quad @ Glamis and asphalt to sand II (Dumont). Our quads best ET in the 1/4 is 10.23 @ 123mph. We run a 443cc Cub on gas, stock frame, +8 swingarm and I weigh 215 lbs.

Yes, we ran alky for 4 years and switch back to gas this year. No regrets, it's plenty fast in either configuration.

Thanks, 7mm cub on cheap race gas. It will be at Olds on the Feb 14th, maybe even the day before.

According to the Mikuni main jet pocket tuner you will need around a 157 jet just for the elevation change. I didn't take into account the temp or humidity. I think you have to stagger jet your carbs, right? The 157 would be for the high side and 2 numbers down would be your low side.

Yes Sir!

I'll be there and will be staying around wash 2. I can't dune, but I'll be dragging at Olds.

According to ISDRA Sand Dune Guide, Glamis elevation ranges from 200' - 500'. When we were there on Jan. 03, 2009 the density altitude ranged from 200' @ 7:00am - around 1500' at the worst during the day. We use density altitude for all our tuning and it takes into account: temp, relative humidity and barometric pressure. You will also have to richen your air screws, pilot jets, needle position and of course your main jets. What type of carbs or jets are you using; the hex head jets or the round style?

No, just taking a needed break from the asphalt quad stuff!!! Our drag cars is what wins the big $$$s to allow us to have our expensive hobbies. We picked up some new sponsorship for this year and my son landed a sponsored new ride.

NYUK, You wanted more video here it's I hope. Trying something new to me using photobucket. 1st one is my son @ Comp Hill, next 2 are me @ Comp and the last is me @ Banshee Hill.

We went to Glamis for our first time ever at/on the sand with our 1/4 mile asphalt Banshee. We were at Oldsmobile for only one day Jan. 03. I didn't get enough and we are keeping the quad on the sand for a few months. We plan on being there for presidents day weekend and will only be hill racing. http://s143.photobucket.com/albums/r143/BL...w%20Years%2009/ http://s143.photobucket.com/albums/r143/BL...nt=100_0533.flv

Yes, that was me.

Yes sir.

I agree, we had one next to us that was a total mudflower!

I think we are going to keep it set-up for sand for 2 or 3 months. Looking to do a little organized sand drag racing also. I'm at the mercy of my one sand friend when I go out. I haul the trailer out with the 2 wheel drive, but need the 4x4 to get to the hill. I might be able to make prez weekend.

7mm cub on race gas, did we meet or did we run you? Yes, we ran the street drags qualified #1 and won the quick 8.

Actually we had a blast and I'm sorry to say we did take it serious. We took a lot of crap about the hill being different than asphalt drags. We had it dialed in within 4 runs, with help from the Jockey and some advice from Kevin Herr.
