    I searched around a bit and couldn't find much help. I was wondering where to purchase a quality chain and what is a good tooth adjustment either front back or both for more power. I plan on replacing the chain and both sprockets. Thanks in advance.

    JT SPROCKET from what i heard. i heard the 520 chain conversion works(u can search that hear)..mixed reviews on it though. 2 up in back and 1 down in front. or stock front and 2 up in back...i think over all the 2 up in rear offers more acceleration...i think i remember reading. but it will throw ure speedo off.

    Thanks for the response. I think the speed reading for the 86 comes off of the front tires rotation so I wouldn't imagine it being affected by a sprocket change. Or would it?
    Can I get a chain from the dealer and then get aftermarket sprokets with the 2 more teeth in the rear or does it require a different chain setup all together?
    Any info is helpful. Thanks again.

    No chain/sprocket setup will find you more power, but you can improve acceleration at the cost of increased engine wear and noise and worse fuel economy by changing sprockets.

    Stock Honda front sprocket is quieter than any aftermarket cuz of rubber dampers, and you should stick with a steel rear sprocket, cuz alloy will wear about 3X faster.

    You need to find a quality, name-brand O-ring chain online.

    Replacing components is not cheap, and for durable parts that last, you'll need to spend about $140-$180.

    I would stick to 530 and go with a less expensive O-Ring chain, they all wear out sooner or later. If you believe the manufacturers info, the 530s will have higher tensile strength for the money than a 520. Measure the chain under tension and change it when it wears (elongates) 3%, the starting value is 5/8" per link. My 86 came with 16/46 JT sprockets. I ride a lot of 2 lane roads and it works pretty well. I switched to a 750 engine and am getting 46 mpg.

    Are 16/46 JT sprockets stock? How many links does your chain have?

    16 / 46 is stock for 700. i think a 110 link o ring chain will work from my research.

    I know I need a manual. I've been spending on this thing as fast as possible since acquiring it recently. Chain and sprockets and brake pads and fork seals took precedent over a manual. Thanks for the info, I'll have to rely on VFRworld until I can fit the new book into the budget.

    I'll do that as soon as I get 5 minutes to, I had one of these back in 1987 and have had the 2003 VTEC 800, VIFFERS RULE! I had the VF1000R, never should have sold that one.
