Question for the duners

**twyztid** · 10-26-2009, 04:43 PM

Sorry that this is a bit long.

I am running a stock motor with the bolt-ons in my signature on my green V. When I had installed the 4" swingarm extension I found that the 24" 8-paddle Extremes weren't enough paddle anymore. Before the extension I could keep the front end down and after I couldn't get it to come up. I was wanting to try some wheelies because I haven't really learned to do that yet but with the extension and those tires I could sit on the gas cap cover and still couldn't get the front tires off the ground more than about 6" on flat, wet sand. When I would drag race on wet sand or tilled dirt/sand I could sit on the very rear of seat (almost hanging off) and the front end would only ever come up about 4"-5" on the launch. I realize that is a good launch but I shouldn't have had to sit back that far.

I decided I needed probably a 10-paddle tire so I just bought a pair of 25x12-10 10-paddle Extremes and tried them out in the dunes. I like them a lot and I will be keeping them but I still can't pull the front end up very far from a full throttle start on wet sand. I am assuming it should be easier to do on wet sand than dry sand.
Why would this be?

Is it because my frame is just over 1" closer to the ground by where the front of the nerfs mount than just behind the pegs (sloped forward)?
I already have the lower shock mounted in the rear hole on the swingarm extension and I don't want and less preload on the shock.

Does a stiffer or softer rear suspension cause the front end to come up easier?
I had thought softer suspension would do that but when I went to the Road Magnet springs on my orange V, it seemed like the front stayed down a little better with the softer rear spring.

I realize that more power would cure the "problem" but that isn't going to happen for a while. I was just hoping to find a tire that would launch good if I sat just a little further forward and leaned forward more than normal or would wheelie if I sat just a little further back than normal and pulled on the bars. That's wasn't the case.

What do you guys think?

You can see the frame sloping forward in this picture.

put stock wheels on it and practice on the road and wear a back protector and have ur foot on the back brake and be ready for some pain

Ummmm... NO.

IF I learn to wheelie, it will be on the sand. I could learn on my orange V if I wanted to. That's not the issue. I just thought it was strange that I couldn't do it even with the 25" 10-paddle tires.

What psi are you running in your paddles

Can your bolt on engine pull the 25s?

The +4 moves the weight bias forward as well. The front is heavier so your having to lift more weight.

I tested the very same 25 combo you have at St. Anthonys. Sugar sand though. My 730 did not want to lift with the +4 bolt in. The front would get light but not wheelie. I'm pretty big though so the bike has to overcome my 245 lbs as well.

The 25x10x10 10 paddle extreme or ripper is what I hope to get by next year.

I was running 3psi on Saturday. I had usually ran my 24" Extremes at 4psi. Those worked the best for me at 4psi but I had dropped the 25's to 3psi to flatten them out a little. At anything under 3psi (or maybe at that pressure also) I think there is not enough air pressure to keep the paddles from folding back a little.

The 25's seemed great on it. I raced 3 Raptor700's Saturday about 8 times (one of which had dual exhaust, filter, and power programmer) and beat ALL of them every time.

I am around 180 but I was sitting within about 1-1/2 inches of the rear of the seat. I guess I may have to sit back even further if I want to try to wheelie it. It's funny. I was worried that I would have a problem keeping the front down again with the 25" 10-paddle tires.

They make a 25x10-10? These are a 25x12-10.
Sorry I scooped them from under you... well, maybe not.

Heavier machines requires wider paddles, higher horsepower means you can pull taller paddles.

You may have gotten yourself into a pickle using such big paddles.

I would think that I would have a problem spinning them if they were too big. That doesn't seem to be a problem. I think they did help my speed in a 300'-400' race in the dunes.

It would be interesting to see how the engine tach's out with the different paddles. I wonder if you are loading the engine too early. Perhaps a bit of a clutch tweak may be in order? How did the bike characteristics change when you changed tires?

The +4 bolt in is very effective though.

I thought it 20x10x10. TRUGRIP let me borrow them for an afternoon to try. I just glanced at the sidewall. I really liked them. Better grip but you could still break the rear loose if you wanted too. Not a drag tire by any means but a real good duner.
