Thats just above stock, just above and no more, how the hell did you ever get it to run on an 84 main jet with an open filter? Mustve been lean, i cant see how it couldnt have been lean if stock is 82 and you lobbed in all that extra air? Unless the open filter was tiny and didnt allow air to flow well?
I am in Scotland, 60mts above sea level, mostly mixed weather from sunny to raining, lots of damp days, some humid days some not, never really too hot. My open filter needs a 92 main jet.
Most online shops advise going upsomewhere between 10-15 sizes as a guideline when fitting a open filter.
It was the size and shape of
this, but it was an unbranded copy and not the polini filter i'm linking to.
I was able to run an 86 jet too, but couldnt feel any power increase, so i used #84 for the whole time i were using it. This were mainly over the summer, and i also tried with the
doppler air box but it kept falling off, due to lack of space between saddle box and rear tire. Even when it fell off, and i were running without any filter, i were running great and powerful, so for me, jet #84 and #86 were the jet needed for free flowing air. If i went any higher than that, it would be flooding. :p
I also tried a tiny filter like
this (possibly a little smaller, i dunno the real size of that stylepro filter), but no matter what jet i had in, i couldn't start the scooter.
