The best thing about the mx track to me is that if your bike breaks down you don't have to push it 5 miles.

Yeah, definitely. Hell I notice something like that on the 450. It's not going to like handicap you or anything but there will be a noticeable sluggish quality when jumping to the 520. Why do you think you need a beefier chain and sprocket? Just want it to last longer or what?

Ride with bros who have a tow strap  Actually, I probably need to add a tow strap to my stuff. Currently have tail bag and front fender bag that I haven't fitted up yet for tubes and irons.

For woods riding elbow pads I like my sixsixone armor suit thing. The elbow pads are gouged up pretty good and I've never had more than a minor bruise on my elbow. I really need to get back in the woods, other than the trials bike around the house it's been at least a year.

Yes but he probably would have broken the bones in addition to a worse knee injury. Damage control.

Just want it to last longer or what? Yeah, I replaced my chain and sprockets when I first got the bike and I've maybe put 100 miles on it since then. It being a peaky old 175 2stroke, I am not real gentle with it and the roller chain wore out fast. The XL175 I believe is running a 520 roller. I was thinking of matching it and gearing down.

Oh ya I would definitely run 520 on a 175 two smoker, without question. Didn't realize that was a two stroke. And yeah, knock off 2 teeth on the rear and that should solve your peaky issues. I always keep the counter stock because it dramatically increases chain wear to run different sizes.

My plan is to shorten it by adding a couple teeth to the rear so I get a more useful 2nd gear for how I use it. My pace on trails with the stock gearing is generally somewhere between the top of 1st and lugging 2nd. I figure if I shorten it I can bang up to 2 a little earlier and be able to ride slower in that gear and maybe get more oomph out of the bike. I don't ever need it to do 55mph like it's currently geared to accommodate.

That's a good idea, I always gear my bike so that first gear is essentially useless aside from putting around the pits. Have you done any mods to the bike to give a bit more on the low end? Changing your reed valve and making sure your intake is unrestricted (like with a snorkel or stock filter with too much screen) are cheap and easy mods to give it more low end. Not sure what year it is so things like exhaust might be hard to find if it's older, but you can mill out the cylinder to give it more compression (more punch) and replace the carb with one that has a higher flow. You can also use a higher compression piston with a bore but that will require using expensive race fuel which is probably not necessary. Also, I was thinking about your chain/sprocket situation and it occurred to me that it may have worn out so fast because it wasn't adjusted properly. They'll wear out really fast if it's too tight especially, that would also explain the unusual roller wear. Make sure you have about 1-1/2" of slack. So basically press down on the chain so its on top of your swingarm, then pull up on it and measure that variance. If it's too loose it'll slap a lot which wears out your rollers and chain guide, and if it's too tight it'll ride funky (it'll feel sort of restricted), wear out your sprocket & guide/roller and also stretch your chain excessively.

I adjusted it every time I went out; ratchet strapped the swingarm to compress the shocks and adjusted based on the rear sprocket at its apoapsis. Mostly I think it's just an underbuilt chain for the abuse it gets - all its miles are in the woods. As far as mods go, it's all stock from 1976 in EPA street legal trim. I am sure it could use a top-end refresh, the piston slaps around something fierce but it starts on the 2nd kick every time and all I have to do is put oil and spark plugs in it. When it finally blows up and I have to work on it, I might get a new MX175-spec carb for it - they're about as expensive as a rebuild kit for the stock carb - and have my pipe made into an expansion chamber. That's supposed to give it a good boost.

Word, that all sounds like a plan to me. However, unless I'm confused on what you're saying it seems unnecessary to ratchet your swingarm up, if you just give the chain 1-1 1/2" of slack while the shock is uncompressed on the stand it will satisfy any tightness it may experience during suspension travel. Just to save a few minutes and effort. But if you've got a good system down then by all means stick to it I'm gonna be unable to ride this weekend due to wisdom teeth extraction  I guess I'll spend the weekend watching racing. If anybody didn't know the entire Outdoor National series will be broadcast live on webcast. Hangtown is this Saturday http://www.allisports.com/motocross/live
