Advice on my 36 tooth sprocket [ speed vs torque ]

[WIZARDOFOZONE]

Yeh, Livefast was it I believe

I think the 40 toother was from livefast like he said above ... No warping after 300 miles ... these are thick and I truly doubt that warping would ever be a problem.

I have one of these 40 tooth sprockets, from livefast on the first MBc I put together. I bent it, when a chain came apart. It was easily straightened and since then I have put over 500 miles on it. In total this sprocket has about 1300 miles on it.

I like the added speed and I can still climb the steepest hills, in my town, without pedaling.

Yeh,that is my experience too ...

The 49 tooth is a right on edge balance of torque ad speed, so I keep eying my untried 36 toother with curiosity. Red Peril is really fast enough and for 2 to 5 mph more I think I'd hate the loss of torque tradeoff. Others say "no problem" with the 36 tooth however . Secondly, I'm getting lazy and my cruiser had that drive sprocket bolt problem illustrated at King's site ... I too had to countersink and use the flat head allen insert type bolts to gain back the precious 1/8 inch clearance between the 9 bolts and the cruiser brake stop lever and mounting bracket, as well as enlarging the center hole to go over the dust cap ... every new sprocket needs redrilled and the center enlarged in this manner and so the 36 toother sits here unless I find a new burst of energy or get so damned bored I do it for distraction.

great thread. i didnt want to go to a 36 tooth because i got this so i dont have to peddle lol. called livefast and what a super individual and price is great. 15 plus shipping for the sproket and mounting hardware which with everyone else i would have to buy seperate. the one that came with engine on mine is a 5 bolt and i think i will like the extra mounting screws. not advertising but i am very excited and will post what i think after i get it and put it on

I have a 36 tooth on my 79cc, very fast on the flats (speedo has seen 35 on the flats) well over that on the down hills. OOOps I should keep that on the DL huh?

BUT

with the torque from the engine the teeth are starting to degrade at a high rate, I think I will go back to my STEEL 44 or look into the 40 tooth, that sounds just right for speed and for take offs from a dead start, traffic light stop sings...

I bought a 36t sprocket and 12g/chrome rim from SPOOKY TOOTH 2 years ago. it's on my old cruiser frame project with twin 80cc engines. if i can successfully leash the power of "twins", 36t will be perfect, even from a dead start.

now all i have to do is FINISH the bike.

Iam currently using a 42 tooth that i picked up at a garage sale . it is a flat sprocket ,not concave like the 44t's i have, but still lines up good with engine sprocket and keeps the chain clear of the frame. .would like a 40t but nothing smaller as theres tons of hills here

40T is a good sprocket for me around here.....

just purchased a 40 tooth sprocket with a three point hub adapter which clamps around the hub of rear wheel,so it drives the whole wheel not off the spokes. Rear sprocket runs true no run in/out and run concentric no up/down wobble,$40 on eBay. Bike is fine with 44 tooth just can't keep it concentric and i get that chain lash,already switched to a high quality BMX chain instead of the cheap Chinese 415 chain. The 410 BMX chain is much tighter and lighter than stock so less noise and vibration. I have a after market spring chain tensioner with a 2015 80cc? slant head on a steel frame 26" Mongoose mountain bike and it does 35 MPH no problem. Besides the chain drive modifications i double stacked the head gasket and put in a NGK spark plug for a jet ski.
