Gearing for Glamis
« on: December 05, 2012, 11:02:48 am »
What gearing is optimum for comp?

Do I want to be running so I hit fifth?  Last time I couldn't hit fourth  :))

But I also like to go wfo on sand hi way to the store, so I still want to scare myself...

Thoughts?

13/40 is stock -

At Silver Lake, this gearing was "ok". 4th and 5th were really fast and I needed to be on the pipe. I want to try 14/42 with my new 2.0 pipe for a little less hairy dune experience. This is with a 20" paddle tire.

It looks like the 42 tooth rear is not a common sprocket.
Ain't ever seen it......but I have heard it.

IMO the 13's are still to small and bind the chain.

Be nice to find a '88-90 bottom end to run instead of splitting the cases ...

We been talking about 4th and 5th gear ratios for over 5 years, Glamis rider reposted  a section on it a few months back, aint cheap to do any more , cost over $300 just for gears, unless you can score a set good used ones.

Wonder what it would cost to have new gears made? Arent they discontinued? Liberty Gear makes banshee primary gears in different ratios. Wonder what it would cost to get 4th & 5th drive and driven made?

And I wonder why you guys are running low gearing? When I thoughy you could run higher gearing like 14/42. Is it in the motor set up no being able to pull it?

13/44 gearing & 10 paddle Haulers is too much for my +4 swingarm & 175 lbs going up the steep hills like Comp, Test, & Patton. But it is fun!

13/45 for now, about to put a 14 on the front.  Tudor dune port, AEM filter, 8 paddle Extremes, Q1.875 pipe, m102 trans, 170#

Pulls really well in 4th and even has some pull in 5th on the str8-a-ways.

I also have a +8" stock swinger. So I think a 10 pdl extreme will work.

The hills are steep enough that regearing is needed to hit fifth and the two dozen whoops at the bottom to negotiate

nothing better then rounding a massive Glamis bowl in 5th pegged.  The g's forcing the suspension to flatten out.   >:D +k2

It's all about preference really.  When i dune i like 3rd to be my low gear.  I click 4th coming out of dune trails into to straight-aways and 5th sometimes in the open areas.  I use 3rd & 4th gears the most.  Although, i do think my gearing is a tad low even for that.  Find myself using 5th a lot.  That's why i'm switching to the 14 front.  Well, one of the reasons anyway.

HRD build, 13/42 stock OEM sprockets, 21" SS1 tire.  I dune most of the time in 3rd.  Use 4th and 5th in the higher speed areas.  With the HPR#19 I can pull 4th up Olds and China Wall.  Oh ya, stock swing arm.  SS2 tires were too aggressive with the stock swinger.  Haulers would have me on my back in the sand :D

I run 15-40 gearing on my 87 .Q pipe cool head and pj 38 carb . The higher gearing still wheelies first through third and flat out moves .
