50 tooth on the rear

[Lildawg]

Changed the rear to a 50 and found it to be the most user friendly by far. Also didn't get much if any squeal form the clutch which has been known to howl from my 250.

i'm gonna try 50t rear on my 300 - it was 13/52 and it was too much... i'm afraid 48 will not be enough..

I like the 13/50 combo on my 300 but 13/49 would be perfect for me if the carburetor was jetted well and the bike had the lighter ignition. A steel 49 tooth rear sprocket is available for under $20 if you know where to look.

13/49 is the magic ticket for me.

i have light ignition, ordered a new ironman combo 13/50(had a 50% off coupon!) it should work well enough i think..
my rear lasted 2 years (close to 1500 miles..) the fronts last about a year. this is spectacular considering....worth every penny.

An old racer told me once that if you want maximum sprocket life, stick to an odd number sprocket on both ends. This way when a chain rolls around the sprocket the links of the chain are wearing on every tooth, not just every second one. If you look at an old worn out even numbered sprocket you'll see what I mean. The inner link of the chain wears out every second tooth. Thus, using an odd number spreads the wear out over the entire part, extending its life. Just a thought but it makes sense to me.

When my 48 wears out, I'll be going to a 49. Sticking with a 13 C/S

where did you get said coupon?! the ironman 51t on the back of my bike has been on it for the past 5 (yes, 5, one of which was a AA harescramble and enduro rider) owners of my bike, and its starting to hook. i would love to put on a new set of sprockets and chain, but the price of ironman stuff, while totally worth it, is awful expensive.

I went from 48 to 49 and now 50 on my 300. I really like a 50T. Hillclimbing is easier. Starting and stopping in second doesn't kill the clutch.

The big gain is with shifting between gears. There is less power drop between gears so traction is easier to maintain by not dropping in and out of power band.......if that makes sense.

As long as when you divide the front teeth number in to the rear number and it doesn't come out even it is a hunting gear set and will wear evenly. 13 in to just about any reasonable number will be fine.
