These are Doug's comments:
Hi All,
I wanted to share with you the easiest mod I've ever done to my bike - I had my igniter unit modified to rev upto 8500rpm, but also to advance the ignition timing by 3° on the top map (the Wide Open Throttle map). This means that at part throttle openings the ignition timing is unaffected (still ticks over smoothly, etc) but at WOT there is a bit of advance. I did a dyno run before and after the mod, with no other changes (other than it was a dry day when I did the second run; a very wet day for the first run, so the second run looks a bit leaner on the air-fuel). Because of the air/fuel mixture difference, I reckon the second run is showing a little less than it otherwise would, so the difference would have been greater if the weather had been the same.
According to SOP Dyno, the bike feels much livelier than even the graphs would suggest, with better throttle response and a huge top-end.
Conclusion - for the small effort and reversibility of the mod, the improvements are significant! I would definitely recommend this mod to anyone who wants "quick and easy gain". |

Doug's dyno shows the T100 increased bhp by 2.4% @ 7,000rpm and peak bhp increased by 7.3%. The torque peak increase is 1.3%, there are also gains of upto 3.6% along the curve. |
