Posted May 27, 200420 yr comment_83004 Does such a thing exist? I have the PHH Service Manual (like, 20 pages) and it has some basic info and blow-ups, but is there somewhere a really good tuning and adjustment and explaination document?I have been forced to educate myself because the incompetency of others is greater than the depth of my pocket-book.steve Link to comment https://www.classiczcars.com/forums/topic/11940-mikuni-tuning-manual/ Share on other sites More sharing options...
May 27, 200420 yr comment_83006 Steve, I used the Mikuni manual and an O2 sensor. O2 sensor was added after about 3 months of screwing with them, and I had it fairly well dialed in a couple weeks after adding it. Definitely the BEST thing you can do to aid tuning triples IMO.Wideband O2 is the next thing everyone will say, but I did OK with just a standard O2 and a voltmeter. Our buddy Greg installed an Autometer (I think) fuel mixture gauge with a regular O2 sensor and the guy who dynoed his 510 laughed at him. Then it turned out that the gauge was dead accurate on EVERY pull, and the dyno guy stopped laughing. I do understand that for turbo apps the wideband O2 is a better idea. Can't remember exactly why. I think its because they run a little richer for a little extra ping resistance and the regular O2 doesn't read well there, but for an NA that should be running somewhere in the high 12's to 13:1 range I think the standard O2 is sufficient.Jon Link to comment https://www.classiczcars.com/forums/topic/11940-mikuni-tuning-manual/#findComment-83006 Share on other sites More sharing options...
May 27, 200420 yr comment_83012 Jon, can you post somemore info on this o2 sensor thing? I also have triple Solex's and they could use a good tuning. I'd be interested in how you set it up, and how it works.ThanksScott Link to comment https://www.classiczcars.com/forums/topic/11940-mikuni-tuning-manual/#findComment-83012 Share on other sites More sharing options...
May 27, 200420 yr comment_83013 I used a single wire O2 plumbed into the collector with an O2 bung that I bought at the local muffler shop. Then I connected that to a $6 Harbor Freight volt meter and shot for as close as I could get to ~.75 to .8 volts.

May 27, 200420 yr comment_83016 I should also say that wideband is undoubtedly more accurate, but I had to spend that $400 somewhere else.Jon Link to comment https://www.classiczcars.com/forums/topic/11940-mikuni-tuning-manual/#findComment-83016 Share on other sites More sharing options...
May 28, 200420 yr Author comment_83043 I've never heard of the votlmeter thing, but I guess it stands to reason. You can check your fuel level with a voltmeter, why not your mixture?!?!?Jon, Greg and I have the same gauge installed, the Summit $30 LED one. They have changed it a bit, Greg's is (lean) red red yellow yellow green green (rich) and mine is (lean) redred red red green green green green (rich)Anyone want to comment on EGT in here? I would love to hear the comparisons to A/F readings.steve Link to comment https://www.classiczcars.com/forums/topic/11940-mikuni-tuning-manual/#findComment-83043 Share on other sites More sharing options...
