some progress
Hi all.....
I did receive a response concerning my use of the following gear set, but not from here.
It appears I need to find an additional 3:1 somewhere in the drive line??
I'm still going ahead with the 35t sprocket for now, here is what I'm using:
@ 6000 rpm with 10t clutch to a 35t sprocket on the left jack shaft (SBP 4 stroke kit), and
a 10t sprocket on the right jack shaft to a 48t at the crank mated to a 30t that runs to a 7 speed cassette.
with 12,14,16,18,21,26,32 tooth sprockets would it produce the following?? (ball park)
12t 9.57:1 @ 48.46 mph
14t 11.4:1 @ 40.62 mph
16t 13.6:1 @ 34.10 mph
18t 16.8:1 @ 27.62 mph
21t 20.8:1 @ 22.28 mph
26t 24.8:1 @ 18.76 mph
32t 29.2:1 @ 15.88 mph 1st gear
I really don't know if this will work but it seems as though it should......that was my question.
Is this approach reasonable enough to accelerate from a standing start in 1st gear with out choking down, and allow advancing thru the gears to a sustainable 25+ mph.
Just asking for opinions, if I'm all wet that's OK, I just don't wish to spend $150-$300 on a gear reduction 'transmission' when I have a gear that may(might) do the trick
I tore down the bike and have completed painting a have the initial re-assemby done.
Have parts coming in ....
Had to use steel wool on the handle bar and goose neck to clean them up.
Put on the dual brake lever and front brake disk 160mm.
I slipped on a new twist shifter and determined that the throttle and kill switch when installed will prevent it's use, so I'm getting the thumb shifter, hope it works better.
Have new rims, strips, and tubes, rims are Sta Tru with disk brake hubs on both, and a new 7 speed cassette.
Here are a couple of pictures....
