trail riding yz80
« on: May 06, 2013, 02:48:38 AM »
I recently bought a bone stock 2000 yz80 and was hoping to trail ride it, unfortunately, the bike is incredibly difficult to deal with at low speeds in tight sections. Does anyone know of any cheap or free mods to allow for more low end power? (other than a sprocket change)

Torque spacer might help, could make one pretty easy

Flywheel weight?  Check Steahly Offroad to see if there is a flywheel weight for your bike.

It's a small bore two stroke, I'm not sure how much bottom end power you'll be able to squeeze out of it. The right pipe combo might help, also porting it for low end power would, but those are a bit pricey.

There used to be a member on here that used to build bikes and was always talking about ways to make small two strokes run more like a four stroke for woods riding. Something with the reeds I think. Anybody remember him?

I've found that the porting pretty much typifies the machine, in other words, it will be (very) difficult to find low end power in a machine tuned for top end.

Step one, different sprockets.
Step two, make sure your clutch plates are in really good shape. You will use them a lot.
Step three, have a blast!

You have the absolute lightest trail bike out there! It will not be as forgiving of engine usage mistakes but if you can master it you can ride ANYTHING in the woods!

Citabjockey is right (wow that was hard to type  ;D) You many want to lower your gearing by either dropping a tooth on the from or adding teeth to the rear.  Bur most of all, see step 3 "have a blast!"

Honestly the easiest and cheapest way to get bottom end from a yz is to swap it for an rm, the rm has a powervalve and the yz doesnt so the rms power is spread out a lot more. Trust me I had both.

Motocross yz is best, but enduro is where the rm begins to kick ass.

Honestly you won't be able to get much torque, if any at all, out of a yz80. Is it jetted right?
