    Nice work Dex! Have you had it out on the road much in that format?

    That seems like a hell of a long drive to dyno, nothing decent down your way???

      air/fuel is up and down badly , you should pick it up at least 4-5 hp when its all sorted. btw how much did it cost ya, how long were you there?

        Agreed ,, fuel map is " wonky " at best .
        Little bugger pulls like a train as is ,, being thoughtful of mechanical sympathy.
        Should pick up a few more hp and the torque curve should improve somewhat with it .

        Main dyno joint " reds " is on down time due to health concerns,, and other joint seems same .
        So the 2-1/4 hour drive was well worth it .

        Spent an hour up there ,,, usually does 3 runs ,,, bloke up there loved it so much he did 7 .
        Cost $100 , and he laminated the final data sheets .
        Champion .
        A fun day was had by all ,,,cheezy grins ensured .
        its engine oil madge ,,,
        Your soaking in it ,,!!

          I think that is a bargain Dex , I'm sure it would be 2-3 times that in Sydney. well worth going again for a bit of tuning. great post mate!

              I know up here a dyno tune (and only a tune) is in the vicinity of $450

                    Starter motor sprag started to slip .. Seems to be a thing with them as standard .
                    Going to the tb barrel and head made this more aparent ,," loosing the factory decomp " and the comp increace .
                    So a takegawa s35 decomp cam got slipped in yesterday .
                    Start up is quick and direct now .
                    Another dyno day is being organized to get this bazzaz fuel module sorted .
                    its engine oil madge ,,,

                      hey Dex , did you put it back on the dyno to fix the air/fuel ratios ?

                        Occy strap is enough to hold it on dyno. "she'll be right"

                          Bloke has been playing with the program on the bazzaz fuel mod .
                          With some success,, but still an unknown quantity till it ,, the laptop and cords get taken back up north to dial it in propper .
                          Should see power and torque hike up somewhat when its crisp across the board with the a/f mix optimized .

                          Next missiion is to remove the 10,000 rev limit ,, to allow the cam ,and titanium retainers and all mods to realy sing to their full potential .

                          Doubling hp and torque has been cool at the same rpm limits still quite a big leap tho ,,
                          Even with the a/f ,,,,,wonky ,," at best "'

                            Just wondering what sort of fuel range you guys are getting with your z125’s and groms
