    I had been running stock 16/42 sprockets on my SL350-K1. It runs about 6K at near 60mph. Swapped from a 16 tooth front sprocket to a 14 over the weekend and tested it yesterday. Never hit 50 mph at 6K and didn't want to push it more. BEst news was the stock chain did not have to have links...

  6. 1978 Honda Hawk Rear Sprocket Plate?

    Tires, Wheels, and Brakes
    Hello everyone, I was hoping you all might be able to give me some help. I'm trying to replace the rear sprocket on my '78 Hawk TII. However, I've noticed that all of the replacement sprockets are all just a sprocket unto themselves. The stock sprocket has a back plate of sorts that is riveted...
  7. '72 CL 450 - Putting the motor back in

    Frame, Suspension and Steering
    Today I'd like to put the motor back in to my CL450. I have the service manual (thanks to HondaTwins members for that) and it says put the motor in from the left side in. It doesn't say much more than that other than how to fit the ground cable on (do I need to sand off the powdercoat where...
  8. auto oil schproketz

    Engine Discussion
    I have a '72 or so cl 450 with the oil valve built in to the sprocket, There is a thin metal retainer that prevents the sprocket from coming off when unbolted. I believe it was missing or removed from the '71 parts bike because the sprocket and retainer came right off. What gives with the stupid...

  11. I'm ditching the electric starter. Is removing the starter sprocket necessary?

    Engine Discussion
    Title pretty much sums it up. I've removed the starter, the small starter sprocket, chain and side cover. I can turn the crankshaft just fine with the larger sprocket still on. Is it okay to leave it on there. I don't really want to mess with pulling the rotor and risk messing something up. I'm...

    Hi I've got 1983 CB400T. Wondering if anyone had experimented with different front and/or rear sprocket sizes to improve top end speed and how far is too far in terms of affecting rideability. Thanks in advance, Dan.
  13. CB400T sprocket conversion?

    Engine Discussion
    I'm going to be changing out my sprockets and chain on my 81 cb400T. On my GSXR I had a 520 conversion kit for more off the line power, is there any type of sprocket conversion kit for an old CB? Not to to stunts like I was going for on my GSXR but just for better overall performance of the bike.
