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.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 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.
where did you get said coupon?!
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
Probably make a pretty good trials bike the way you have it set up.I run a 12 -50 on my 300 I'm 255 lbs and like chugging up hills and over things I rarely need to hit 50 mph around here But i like to ride 1mph without stalling I use a g2 with slow cam to help the o s-it factor. The bike is a tractor.Shes in the basement now and I miss her
