sx 60

51.1 mph with the gp 460 backed the run with my gps, both speedo and gps read the same. the tanaka 47r will do 46.9 both have x can mufflers with internal baffles, elbows and silicone tubes, that reduced the noise, but still a little on the loud side. No db reading but sounds like aroud 90 db, I fly rc planes and they do a db reading before they let us fly so I have a couple of plane in the 90 db range and the bike is about the same. X can with no baffles no elbows, no silicone tubes is extreemly loud.

I am running a 15 tooth on my gp 460 also, I am pushing 6.0 hp. I have 1500 miles on my belt, but I always peddle 7,8 mph before I start engaging the motor, and I ease in to the gas, and the few times I went for top end 56.3 mph I did not give it full throtle untill I was over 30 mph. I baby it!

Do you mean that you have 1500 onthis belt?

How about you previous belt?

My 1st belt only lasted about 1500 miles with a gx 35. Now with the tana 40 i alway look make sure that its centern on the gear. 1000 miles so far. I like the tan way more tha the gx.

gp 460, got it at davesmotors.com. some mods will have 2 b done like much lighter clutch springs and a different muffle. I think a Tanaka 40 would be a better choise!
