    Triple Bypass DIY or Professional?

    Hey all!
    I am new here, as I am also pretty new to motorcycling in general.
    I know there are plenty of posts in regards to a triple bypass but none of them really help me decide what i should do..
    I have owned my 1980 CX500D for almost a year now, and have learned quite a bit mechanically on it; however, I think the time for a triple bypass is quickly approaching.
    I am trying to decide whether I should go to a professional and spend the money or try to tackle this, learn some stuff, and possibly experience some serious headaches, and try to save some money.
    I know at my local shop a triple bypass would be at least $1300, and from what I have collected the parts alone would run me 300-500?
    Thanks in advance,
    1980 CX500D

    It depends mostly on whether you have a good place to work on it.

    Search the forum, search the Wiki.
    Its rare that an original problem develops in a 30 year old machine.

    Your question has probably already been answered.

    I have an empty garage that loves company, and a pretty full tool chest(given that no super special tools are necessary for this) it would probably be my may/june project

    What makes you think that the time for a triple bypass is quickly approaching? Stator not charging the battery? Leaking from the weep hole? Noisy timing chain? Have you done the "dental mirror" check for timing chain adjustment remaining?

    The clicking/ticking sound seems to be getting louder, I have not done the dental mirror and don't really know much about it in general to be completely honest.
    I'm also running at 44k as of two weeks ago. Any tips or suggestions are greatly appreciated

    Have you done a valve adjustment? That could eliminate your clicking/ticking noise.
    I wouldn't tear into it at the beginning of summer unless it's leaking or won't run.

    From what you state, you sound perfectly capable of taking on this task. And with the vast resources on this forum, such as the WIKI (and other links below), you should be fine and dandy. If the simple task of doing the valve adjustments and cam chain adjustments don't quiet things down (which is highly likely) then we can diagnose from there. Get the free to download FSM from the WIKI for your particular year and model. Read up on the triple and post pictures.

    Excellent advice! Those often overlooked periodic maintainance procedures can keep a bike on the road and save $ and time. If that doesnt quiet things down I'd be surprised. No water-pump leak+ quiet engine = good to go!

    I'm with Relic and Wildbill do the adjustments and diag's first. I was never good with a mirror to check the cam chain and ended up buying a cheap USB Bore scope to use with a cell ph. camera. The triple bypass is not hard to do and there is a lot of help here to guide you along. I'd wait till fall if possible to save your riding season as noted. So I'm a non-voter here so far
