4G Huffy Cranbrook

My Cranbrook is now 4G equipped. Originally had a 56t sprocket which climbed good but slow. Now the cranbrook has a 48t. Still climbs good and top speed is almost 29mph. Bike does what i want it to. 200+ trouble free miles since the installation of the 4G. The Grubee HD axle is great. I have a manic mechanic worksman wheel [11gauge] with the manic sprocket adapter that is on the way. At last a dependable motoredbike.

How is the sound compared to the previous exhaust?
Is there a power gain or loss? I read somewhere that there is a slight power loss as it's not a tuned length item.

Is the chain tensioner sprocket the 11t of the 4g drive , the small one that drives the chain?
 
Indeed nice bike. And thanks for the info on the 4G system. I had heard different things about them and didn't know if they were reliable or not. Has helped me make a choice of what my next project will be.
 
I have a grubee cruiser with the hua sheng 4 stroke with the 4G belt drive and a 44t rear sprocket with sik bike parts air filter. This is the most reliable bike I have ever had after owning a few 70cc 2 stroke.
In summer, iit handles the heat extremely well. You fill up in the crankcase just like the lawnmower. It has a centrifigual clutch that never slips, plus it's a auto clutch. The bores I been told is made of steel so it ain't gonna warp easy under heat like the 2 stroke. So far it has done nearly 4,000kms in the 12 months I have had it. Plus I ride it hard too.
No more mixing fuel and oil plus fuel economy is twice better.
Just regular oil change and checking the 4G belt tension is all it needs.
 
How is the 44T sprocket for acceleration? Really the only bad thing i've heard about the 4G is that the bearings were weak on the output shaft, and the belt cover could fall off easily. But that was almost a year ago now that i heard that
