I won a little cash on fantasy football this year. Decided to buy myself a new set of paddles. Had the ole champion beadlocks since the mid 90’s so decided to use them. Got the wheels modified and the new gliders mounted up. Happy with the turnout. Just a bit taller and wider than the SS2’s that I’ve ran for years which is what I was aiming for. Glad I went with a 68” roll out 21” tire. Gonna test them out at Glamis next week. Can’t wait.

Pics. 10 paddles have a wicked look.
-
Looks awesome Michael! I like the way 10 paddle skat traks look too, I stared at mine for a long time after putting the 10 paddle edges on for the first time.
-
Looks great Michael. Agree that 10's look perfect on the R.
-
i thought gliders were the 6 paddles for minis.... those arent haulers?
-
Nope. Gliders. Skat trak will make any configuration. John at sand toyz unlimited had these in stock. Said he always stocks a set cuz they are his favorite tire.
-
Same width as a hauler, just 1/4” shorter. We trail ride close together. Wanted a paddle that wouldn’t be too bad to follow. There’s 10 of them to make up some of the height difference.
-
Michael, do you have a ride report?
-
Not yet. Leaving for Glamis this Wednesday. Need to do some jetting before I really rip on them. Switch from a Mikuni to keihin.
-
Your switching from a Mikuni to a Keihin? Is it a TMX from an 01 CR250?

Who wouldn't lmao!!!!!
-
Yes. I’ve had the Mikuni TMX for many years and it has never really felt spot on

Did you swap out the factory S-9 needle jet for an S-8?
-
No. It’s always had the Same needle from ESR. Not sure if they swapped it or not.
-
Not the needle that goes in the slide, the needle jet is the removable emulsion tube that the main jet threads into. The TMX from the 01 CR had an overly rich S-9 needle jet which made them fat in the midrange & made them feel sluggish transitioning from the idle circuit to the main jet. I swapped the S-9 needle jet out to an S-8 on my buddy's 01 CR & put in a 400 main & it woke that bike right up. It was a different animal after that simple jetting change. Those needle jets are $22 from jets-r-us. The Mikuni TMX has gotten a bad rap over the years but there really hard to beat when set up properly. They have more tunability built into them as well.
-
mikuni can lick my taint lol
probably because Im a simpleton, but always feel Keihn were way easier to tune
-
What you described is exactly what it does. Eddie told me to adjust The pilot and needle leaner to make it responsive. I think the midrange was way to lean. But if I richen it, it Is boggy down low. It was running like shit trying to do tree shots. So boggy it would almost die. Good Info to know. My tmx has the adapter ring from ESR. Fits like a glove but I’m switching to a standard bell for a custom no link intake.

I also prefer the Mikuni carbs because they have more circuits to adjust. The PE, PJ, PWK, Air Striker do not have the ability to change the Air Correction Jet, Needle Jet, or the size of the Float Valve Seat.
Needle jets ware out in all carbs. This is the main reason that needle selection varies among those that have the same engine package as others, but need to have a different needle to compensate for the ware in the needle jet and needles. Another reason that Keihin needle jets ware out so quickly, is they are using a bronze needle and a brass needle jet. Common engineering practice is not design mechanisms using similar base metals for components that have two surfaces that slide over one another.
Mikuni uses a brass needle jet and a hard anodized aluminum needle. Using dissimilar metals greatly reduces the ware on these two components. I cannot remember when I measured an old Mikuni needle and found any ware when compared to a new needle. When I measure a Mikuni needle jet and find ware, I just replace the needle jet and not have to spend $200.00 worth of time searching/tuning for a new Keihin needle that will restore the performance to what it used to be when the carb was new.
I have to use a small bore gage to measure needle jets. You cannot use gage pins to check the ware in needle jets, because the needle jets holes become oval in shape.

Ride report. Gliders worked great. Almost no roost. Handled good. Not too loose feeling. I was surprised they didn’t slide more. Seemed to always drive forward like a hauler. The bite is better than knobbies but nowhere near a hauler or edge. Most wouldn’t like that but that’s kinda what I was looking for. Plenty of bite to climb any dune with ease. I was considering a 9 paddle, but I’m glad I got the 10 paddle.
-
I have read on forums in the past that a paddle is unnecessary in the Glamis dunes. As a matter of fact I have read several heated arguments about tire selection for the California dunes. I have always used haulers on all my quads and couldn't imagine running knobbies.

I would definitely use paddles at Glamis... Michael if you don't already have a steering stabilizer there worth every penny & when you set them up on the tight side it makes it easier to throw the rear end around. Even with standard 8 paddle haulers I couldn't throw the back end around very easy without really yarding on it. Now with the stabilizer I just have to do a little twist & it practically throws itself.
-
is the sand there much more coarse?
-
The sand varies Glamis because it is so huge. There are areas where you feel like you are sinking in. It’s definitely different than Oregon though. Oregon seems softer and even when it’s wet it’s still seems softer.
-
I remember glamis being dusty and very course sand. But that was many moons ago when I was there.

Yep same. I went once in March and it was soft, and dusty. Could you ride around without paddles? I'm sure, but I'm also sure it would be a PITA on hills. But I have seen pics from people there in November-December when the sand seems very firm, might be better without paddles that time of year.
-
seems like it kinda depends how much power you have as well as the sand being wet/coarse. knobbies dont work worth a crap on a blaster, put the same tires on a zilla and off you go
