Cheers lads. Well we possibly found the reason of the loss of power.. When I checked the ignition map on the laptop, the base advance setting had defaulted back to 10 degrees from the 16 we had set it to, which matched our modified flywheel. We modded it so we could get more max advance rather than be limited by the stock lumps and we found we could rotate the flywheel round on its mounting bolts to raise it up..of course this puts the base advance higher but it doesnt seem to matter. Another way of doing it would be to extend the lump with weld and machining it after to make it look bonny again but because our fylwheel is lightened too we were concerned about the heat changing the strenght of the metal. So, with it defaulting back to 10, we lost 6 degrees from the whole map..effectively giving me only 26 degrees advance instead of 32...this explains why we had to jet down and the loss of power too. Why it would default back is anyones guess and I cant be sure if the whole map defaulted back to the Ignitech standard map either as i didnt save it..but with it correct again, it revs up smoother and a lot sharper too. Shoulda checked it after Brands, my fault entirely...you live an learn, but its not something I expected to happen. A dyno session will help us set it up a lot better..I know Ive said it before, but this time we really need to do it ! Also played wround with the seat position and 40mm further back feels a lot more roomy and means I can get tucked in a lot better, so we will move the mounting lugs tomorrow. Shame about having to scrape away the powdercoating and re-brazing but a rattle can touch up will do and they wont be seen anyway once its done. Looking at the pictures, my seat is now 60mm further back from what the works bikes were in the day...those Italians sure must have been small...or I've got a fat arse? Next week (in my dinnertime at work, ahem) I will make a new nylon throttle tube for the Gunner Gassser with more pull because 1/4 turn is too much for me (I am used to 1/5th or less) and playing around with little spacers on the cable cam today doesnt seem to make it noticeably stiffer either. Getting there... Next round is at Snetterton at the end of April, but really not decided if I will enter as its so fast I may be on a hiding to nothing.. |

Hi there,been keeping a close eye on your progress with your bike and youve done a great job.Ive got an ignitech ignition in my bike and something similar happened to my 900 as i had the ignitech unit too close to my coils and leads.dont know if youve heard of this but these ignitions like to be away from all that stuff.cheers greg |

You raise a good point there Greg, but our ECU is about 12" away from the coils as interference is a killer on any electrics. The Ignitech ECU is mounted behind the headstock in front of the tank and the coils are on the LH lower frame rail...but wiring is a funny business so maybe all is not right? Its interesting to know youve had a similar issue too...we will have another look at the loom and wiring and see if we can see anything that could affect it. Thanks for the heads-up mate, appreciated |

A big thank you! I have probably enjoyed these posts the most. From building the bike, racing and then winning! A real fairy tale ending! Wish you could keep her, someone will be getting a special machine with an awsome history. Best of luck. Lou |
