I don't think they have a sprocket that will fit the GX.
He's on a learn to be civil "vacation" from this site for a week... next time, it's permanent Thumpers ain't JM, or the Oz forum.
If they did, I'll add it to the index.
How about adding this then?
No love on the Stock exhaust core eh GB? Actually, you never added the Protect enduro Undermount clamp to the index either....
What? mods can't see invisible links?
Fine I'll use a normal one. About rear sprockets.
Give me some links bro!!
So I purchased a steel shifter replacement and decided to go with the Moose shifter as recommended by Bert Fox (The Thumpertalk Part# 1602-0015 for WR250/450). Upon receiving it I decided not install it for a couple reasons:
1) The shifter sticks out about 1" further than stock, hence increasing the likely hood of it hitting the ground and potentially breaking the shaft.
2) The shifter is uber thick steel and in my opinion wouldn't easily bend in the event of a touchdown.
So back to the drawing board for me. I'll be trying one of the others soon.
Here's a pic of my experience:
Looking at the other recommendations and have a question. Isn't the "99-06 MSR YZ250 shift lever (PN 34-2148)" a stronger aluminum replacement, NOT a bendable stell one? Let me know, thanks.
I bought the MSR shifter and it's a pretty hefty chunk of aluminum. I drilled if full of holes to weaken it some. Guess I won't know how well it works until I throw it down.
I have the 34-2148 mounted on my X. At first look, it appears thicker and much stronger then the steel version, and I was reluctant to install it..but after my stocker finally broke off, I did go ahead and install it...
Soon after, I slid out in a grassy field and bent the aluminum shifter quite badly...but I took out a wrench, and bent it right back...I think it bends where it needs to...
So I don't know what the exact answer is, however it's not as strong as it looks, and they are quite pliable....
For extra safety, i installed a "Brake Snake"...When I fell and bent the MSR, the fall caused the brake snake to break off!! (This pic is with the stock shifter, I can take another of the MSR aluminum one if required.)
toofast: So the MSR shifter end is in virtually the same place as the stocker? The moose one sticks out much further than stock and looks like if I installed it it'd be annoying. Thanks.
FYI - the Touratech F650GS shifter works just fine, and is really bendy.
Do you have a part number?
Folding Shift Lever F650GS (orig length) <-Click Me.
You're right. After using it, I have thought about drilling it to make sure it bends instead of breaking the shaft, but then what's the point, you have to do that to the stocker. I may end up drilling the stock one for use and packing the Moose as a spare if the stock drilled one doesn't survive a bending bak or simly breaks. My apologies!
for changing the front sprocket, how do you guys keep from simply spinning the wheel with the torque needed to losten the bolt? It is not reverse thread right? im somewhat worried to fully force it loose not knowing the thread pattern
First time I took sprocket off it was kinda tough, it was on there tight. I jack the bike up to comfortable working level, remove 3 bolts on front sprocket cover (8mm). Lower bike back down so wheels are weighted (by me leaning over bike from left side to put my weight on it), loosen front sprocket bolt (14mm? from memory) and rear axle bolt (26mm), to provide chain slack. Lift bike back up to work on it. BTW, I've been swapping between 14, 15, and 16 tooth front sprockets. I have the speed vs rpm charts made up if anyone wants me to post them. Or you can go here...
to calculate them your self. The BMW manual has all the data you'll need to input.
May as well post them up. it'd be another nice thing to have in the index I'd say.
