Slowing Down my 426 for the trail

[beasleys]

I need to slow down my '01 426. I am trying to ride on some slower trails and my bike is just too fast and stalls to easy. I was told to raise the number of teeth on the rear sprocket and it will lower the speed. Also I was looking in to a flywheel weight to hopefully stop the stalling. Does any have any advice without saying go by a WR. I ride mainly trails and fire road type terrian in Florida where it is either very sandy or very wet and not much in between. I occasionally will head to the track but very rarely.

i would try the weight befor i got to nuts with the gearing. if you lower the gearing too much it can make the bike too responsive. ie wheelies on singletrack etc

[firezwr426]

drop one tooth on the countershaft... quick easy and inexpensive..

[beasleys]

Should the countershaft be done in conjunction with the Flywheel Weight

[wr450fyamaha]

just drop one tooth on the front sproket....that will make a major differance!!!

I have the same basic needs and put a 12 oz. flywheel weight, two extra rear teeth and a Rekluse auto-clutch and the Rekluse made the biggest difference by about 100 miles. I really don't need the lower gearing now as the bike simply will not stall and can motor through anything. I will go back to standard gearing next time I replace the chain and sprokets. Most guys who run the Rekluse are not using a flywheel weight either, although I think it helps smooth things out. The word from me is Rekluse, Rekluse, Rekluse.

How much and where can I get a Rekluse auto-clutch from? Does it change anything else on the bike?

add a tooth to the front sprocket

[ovrrdrive]

add a tooth to the front sprocket

You have that backwards.

Add to the rear or drop from the front.

I dropped one tooth on the front of mine and it helped a lot.

My '02 has the 12oz FW weight, 14/51 gearing, a steering damper and is perfect for the woods. Don't go to a WR, it's too heavy and too sluggish if you're used to a MX bike. I also don't agree that you need a Recluse, now that mine's tamed down I hardly ever touch the clutch at all. I'm in 1st or 2nd in tight singletrack and only use the clutch for a sudden throttle chop if I hit something to save from stalling.

I have an '00 YZ that I use for woods. Go up 2 on the back. I have a stock flywheel and it works fine.

WR suspension is way better in the woods, especially if there are a lot of roots and logs.

You can order it from their website but it also can be found on the TT store (always nice to support the nice folks who provide us with this wonderful site!) It's fairly easy to install. Do a search on "rekluse" on this forum and you'll find a wealth of information--as well as stellar customer reviews.

I agree with OldenPhatt! I installed a Z-start on my 01 YZ426 and now have fun riding trails agian. Best money I have ever spent

I know this is shot in the dark but, does anyone have a 12 oz. weight that they would want to part with?

[beasleys]

For the ones that are running weights. Are you running the added weight to your stock flywheel or have you replaced to the whole flywheel for another heavier one. I was looking on the the stealthy website and they have two options, $150 for the added weight to your flywheel or $200 for the complete new flywheel. Are there any pros or cons to each other than being cheaper?

[Goosedog]

Spend the extra $ and get the complete weight. The bolt-on could decide to un-bolt.

A quick, easy, and cheap test is to buy a 1 tooth and 2 tooth smaller front sprocket and try that. Stock gearing is 14/49- for a long time I ran 12/49 and I really liked it when the going gets tight or steep. I'm currently running 13/52, which is basically the same as the 12/49 setup. I'm really thinking of changing to 14/52 though, lately I feel like I'm running out of steam too fast. A new front sprocket will only run about $12, and it's way cheaper and easier to change than the rear until you figure out what you like.

I had the same problem with the stalling at first. You'll get a better feel for driving the bike in the slow stuff after a while... Another easy trick is to turn your idle up just a bit, I found that it helped a lot for the stalling in the tight and slow stuff, made a big difference.....

[firezwr426]

one tooth up front is about equal to 3 in the rear... make your big change up front, then you can fine tune it with the rear...

[simimi]

just one more input, change the sprockets. Front sprocket from www.rockymountainmc.com = $5.99, and while the rekluse sounds great, it is in the $400 range.

I went down 2 teeth in the front and think that will work best. When I get new chain and sprockets I will 'balance' it out, as I hear the smaller fronts wear chains faster, so I will add as many as I can to the back, and add back to the front, so instead of 12/50 like I am now, I may end up with a 13/53.

one in the front equals about 3 in the back, and the fronts are easier to replace, and WAY cheaper.
