Ok well as most of you know I did a full Area P carbon fibre exhaust, raised the needles 0.06 and removed the snorkal. Been running it like that for few km's now and the bike had its first service today and dyno run.
So a ball tearing, wheel smoking 29.4hp. That translates to a increase of 22.5% if the stock figure was in fact 24hp. Not a very pretty curve at all, and by the looks of it pretty lean. Anyone with the know like to comment? Fuel was Aussie 91 octane.
I'm thinking jet kit next. But for now I might just whack the snorkal back in.
you need a dyno-jet kit, the bik is from the factory set to too litle fuel(emmision isues) and when you put a open exhaust system on, it runs too thin....Dyno-jet is the way to go ! mine with new airfilter has 33,6 hp
yeah i think rejet will be the way to go, just dunno if i wanna spend to much more one the bike, as its running well atm coz ill be upgrading in a year or so but hopefully resale will still be good especially with full zhorst
Like turblown said, you're only too lean in that one spot, and the a/f ratio looks like its going as lean as 14.7 at 7500rpm. That may be where the needle is fully open but the main jet isnt putting out enough. I dont think any more spacing on the needle will help.
Honestly if you want that nice flat curve then you would either need lots of time messing with different jets...or fuel injection.
Yeah I cant 'hear' any pinging... and with the higher octance in today, no change in noises. But it is hard with the AreaP to determine any engine noise. It 'feels' ok through the revs, no lag spots etc. I might hunt for some more washers and give that a shot next weekend, got a pretty big weekend of modding planned for this one. Dont think I can squeeze in re-shimming to.
Oh and give the screws a turn to I guess, it would be better to get it back on the dyno afterwards, but its just finding the time.
