    Front sprocket rubber & 630 to 530 chain

    … my bad — been doing too many numbers and my brain is numb ! at 50 MPH I’m doing almost 4,000 RPM, and I would like to bring the RPM’s way lower this chart pretty much matches the numbers I have recorded

    Front sprocket rubber & 630 to 530 chain

    so the rubber did fit ok, I see so I have a question I hope u can answer … with your current 530 setup ( 17T / 48T / 109 link ), what are your RPM in 5th gear at any given speed, do you have any numbers ? my current 630 setup ( 15T / 38T / 90 link ) is insanely short-geared, and at 50 MPH I’m...

    Front sprocket rubber & 630 to 530 chain

    hello millsmobile so what did you end up doing … did it fit after all ? did you replace with a different one ? I’m trying to do same — go from 15T to 17T on front, and would love to also convert to 530 thanks for any help you can send this way ! — Luis

    SPROCKETS & CHAIN S.O.S. ( from 630 to 530 )

    hello old friends -- my modified '79 CB750F S/S has the stock final-drive setup: 15T front sprocket and 38T rear, with a 90 link 630 pitch chain so the bike runs great, but I wish it was geared a bit taller -- at 4000 RPM I’m doing 52 MPH in 5th gear, and I certainly would like it to reduce...

    Steering Stoppers

    thank you for the advice, JP I was a bit late asking the question, for the fork and al cables and wiring are already in place :-/ , so I'll most likely try to mechanically connect a spacer on each stop -- thanks again for the help !

    Steering Stoppers

    For my current build ( ‘79 Super Sport resto-mod ), I would like to limit the steering turning by about 1/2” on each side — this to allow enough clearance between controls mounted on the clip-on bars, and the gas tank, and prevent contact. Any suggestions out there ? Has anyone done or tried...

    frame-mounted OKI Spark Units and Rectifier

    Now in the process of re-assembling my electrical, I have relocated some of the items: The two OKI spark units and the rectifier. Question: Do these units need to be insulated, or can I mount directly on the frame without insulation ? I am not sure if they use the frame's ground polarity to...

    Fuse Box - '79 CB750F S/S

    In converting this bike into a race-replica, I had to reconfigure the electrical harness, build a junction box under the seat, shorten some of the control wires ... and now I am confronted with the fuse box. I have deleted the turn signals, and I have built a new dashboard which includes the...

    thank you S/A/M I have SHORAI batteries on two of my other motorcycles ( '76 BMW R75/6 and '76 BMW R90/6 ), and I've had these batteries since 2018 -- never a problem, and they still work perfectly, even when I don't ride these bikes more n 200 miles per year at most. At idle, the generators...
