Anyone running 13/38 gearing?

[flauge]

Ive been trying to get my gearing how I like it for XC and Im wondering how 13/38 would be. I started with 15/38 and most of the time I was banging the rev limiter in 2nd. Tryed 14/38 and 2nd was just too short and 3rd was too tall for my liking. I even tryed 15/36 at my last race, it wasnt too bad, I could just leave it in 2nd for most of the time, but it hurt my bottom end too much.
I looked on the gearing calculator for the 13/38 setup and it looks like 3rd gear would top out just a couple mph above 2nd gear on the 15/36 setup. Sounds good to me. How about yall??

I have never tried going wit that setup but I have tried the 14/38 15/38. I have a 416 kit with a slip on and the stock gearing actually works better. I feel like I dont have to shift as much. Let me know if you try it, I may want to consider it.

13/38 works very nice in the trails. i find that first and second go by quickly but third seems to have a nice speed crusing thru the trails. you are going to lose some top end, but you are running xc so that shouldnt be a problem. bottom end is great and if you need just a little more power downshifting gives you that little extra you need

yeah 15/38 works really good. If the quad is mostly stock its a bit too tall but a pipe, air filter, and a 6 degree timing advance makes up for that tall gearing. 15/38 is my favorite gearing.

I run a 13F/39R set up on my 06' when I'm at Glamis. It's geared really low for hill climbing and tearing around in the soft sand.

Im hoping that with the 13t sprocket itll put it right in the sweet spot in 3rd. I dont really care about top end speed with the 400 anymore, its my xc bike now. Im getting another quad hopefully at the end of the month and that'll be my cruiser.;)

I almost forgot, with the 13/38 will I have to go down to a 92 link chain or can I keep it 94??

[flauge]

anybody?:confused:

man idk how you go lower than 15/38 with all those mods your have.

[skidoome]

my 02 is geared 13/38 for the dunes and I like it. 20 inch sand skate II's. At home in the mtns. I run 13/38 with 22 inchers on and it still works well with the stock chain.

I run 13/38 with 22inch maxxis all trak and the low end is great for hill climbing. I wanted just a lil more speed cause i was hitting rev limiter on the road. I went with a 37 and will try out this weekend.With the 13/38 you can sit on the gas tank and handle bars and pull wheelies and i weigh 250lbs.

Can someone give me the link please for that gearing calculator thing again. I know I saw and used it once but I never bookmarked it.

I couldn't even imagine running 13/38 gearing.

neither can I. 14/38 gearing is resonable but I wouldnt do it because its realy torquey feeling bit the gears seem so short. 13/38 even for a 400ex completely stock seems like you would pull the front end up 1st through 4th and your 1st and second gear would be like a blink lol.

[vAnS_77]

I could, Infact I'm running a 13-38 setup on my crf450 hybrid. You just need to know how to ride agresive. Of course every normal trail rider will not want 13-38 but its awesome for the track. If you have massive HP around 50 ish, you want to run a lower front so your quad just pulls like a beast for the track.

[krt400ex]

im actually running a 15/39 and i love it. i can run 2nd gear almost everywhere. i dont use first, and 3rd pulls really far. i run 2-3rd most of time in the trails so i dont have to shift too much.

I knew I wouldn't have to search long to find someone with the same opinion!!!

I bought mine used and it has 14/38 gearing.
I'm pulling my hair out with it after a little variable riding.

It doesn't stall down real easy when taking off on hills. But it doesn't feel like the torque monster people describe it to be. Yet it winds up through 1st and 2nd so fast that at any stab of the throttle you're shifting instantly, yet 3rd is too tall and lugs down too easy.

I wanted to go for new sprockets and a new chain tomorrow, but I'm unsure which way to go.... down to a 13t or up to a 15t... or some combo of front and rear.

I'm at a loss for what to do....

[DuwBra]

The gearing calculator basically said if i had a 200 tooth front sprocket i would do around 1000mph, i think im gonna go with a 201. What do you guys think?

Now that's pretty funny!! lmoa!:D

a 200 tooth sprocket in the rear would need to probally be accompanied with 25" + rear tires, a huge chain, and a captain insano motor lol. Screw top fuel dragsters if you can get going and steady speed past 300MPH I think we may have found a better way to travel around the states lol

[mooseracerX]

I've got a question about gearing so I'll ask it hear instead of making a new thread. Last race I ran 15/36. Off the line I the 450's are pulling right away but as we got to the 1st turn I caught up with them speed wise. We dropped the front back down to the 14 so the gearing is 14/36. I think that should work better but has anyone tried it? I only got to try it against an CR85 hybrid quad and well I smoked it by the 1st turn. Who would have thought a 400ex would holeshot against a 85 and a 195 blaster? :eek2: :D :macho

[04TRX400EX]

I usually run stock 15/38 gearing on mine because most of the trails I ride are pretty diverse in that there are tight, technical sections where I would like lower gearing but there are also long straight areas where I want top-end speed. I change the gearing to 14/38 when I go to the MX track however because I don't need the speed and would rather have more pull out of the corners. I do have a 13t front for the dunes but have never tried it.

I am thinking about trying a 14/37 combination when I change my sprockets and chain because, according to the calculator, I will only lose about 2mph on the top and still get the low-end affect of a 14/38 setup. Has anyone tried this?

I actually just went to that gearing, cuz my chain broke and rear sprocket was worn. I used to have 14/38 and loved it, but the gears were a tad too short. I also went back to stock, but wanted a bit more torque. With this I have more torque for when I'm clinbing the rocky/muddy hills, and it seems to really pull through the gears, too.

[mooseracerX]

^^ Thats good to hear. I was right there with the when I had 14/38 but I had to shift too much. Now we should be just right.

^^ What compression and cam your runnin? Just wondering.

[mooseracerX]

Actually I'm not sure it was built when I bought it. This winter we're thinking of honing and re-ringing it.

[blaaze416]

Groovy. Mine was the same way. But mine was not set up to race...it was a has been. Knocked it out down to the crank....though i should have gone 416, 11:1. I was thinking reliability, since this was my first 400. Then learned more about it. Now, I'd like just a bit more response. I like the 14/36 gearing, but if i had a higher compression/bigger piston, it would be perfect!

I might splurge and get the 426. If I decide to run the "B" class I would need it. BTW here's a great site to look at for parts it has a little about the different motor kits.

[MtnEX]

Still confused on which way to go for me, so I didn't go either way today.

Who makes good chains and sprockets for the 400EX?

[mooseracerX]

SFR makes a good chain and they are only $19.99 don't worry about the low price I use on for racing and it holds up fine. As far as sprocket JT or PBI are great and cheap. You could probably get all three for about $60.

[blaaze416]

Thanks, moose! I may do a 426, too! But for now, she doesn't smoke....ever!!! So, until she needs it, i can't justify the expense! I don't race yet, and when i do, I want to see what everone's runing and how they run it. No what I mean?!?

Mtnex: I just bought a DID x-ring chain, and JT(?) sprockets. My old, Sherpa brand, ebay 0-ring chain broke inside of two months. So far so good for the DID. From what I've heard, DID is the way to go for chains. (and x-ring).

[mooseracerX]

Yea I totally know what you mean. Everyone around here runs freaking 450's. haha I beat half of them on the old trusty ex. I've never broken a chain in two years. (Knock on wood) I've had it come off twice though. Good thing we have 2 extras in the race trailer. I'd get a DID but they are expensive I think and my dad hates chains with o-rings. Don't know anything about an X-ring chain.

[blaaze416]

Only reason I've done o and x-rings, is due to the wet and muddy terrain I'm ALWAYS in. And that's what everyone I talked to told me I needed. Plus, with my luck, when I get the cheaper stuff, It always breaks! X-ring is like the o-ring, without the resistance, from my understanding.

[mooseracerX]

Oh yeah that makes sense. And if they work who cares. :) I've always wanted to try a Sidewinder chain but no way am I spending $160 bucks on a chain that will be just as good as a $20 one.

[krt400ex]

im running a renthal non-o ring chain for the past yr and i love it. it is time to replace it though as it has worn out from the type of riding i do. i ride alot of mud so it wears the chain out quickly. still, i made it a yr on one chain and set of sprockets. not bad if you ask me.

[blaaze416]

^^^ hmm, I'll keep that in mind. How much is the Renthal? It may be worth it to get two,and keep one for a back-up. I've got a frankenchain right now for a back-up. :chinese:

they def more than $20. i paid like $55 for it i think. it was the R-1 works chain from renthal.

[jedneck]

When I had a 440 with port and polish 12.5 to1 and a stage one cam I ran 14/39 with 20 in tires for xc. Get it in 2nd gear and never shift. On a 200 ft drag it whould stay ahead of a tc yfz 450 and smoke a stock 450r. Now with a crf450 with port and polish and a stage 2 cam I ru n 13/39 but am going to try 12/38.
