lid off Mike. In my mind, it may be make a f'glass airbox mold or same size which can be cut down and filter added. Would need dyno again check all ok. Or - cut bottom of tank out - hammer! - and see how that goes

as an aside, with airbox off very difficulty to srat from cold and PC had to be disconnected at first as way too lean. Wouldn't suggest running with PC connected before dyno - who knows what outcome

i know of a 620 which has just come of the dyno and is running no air box just trumpets and foam type filters and is making 65 at the rear wheel and has a lovely smooth power curve .

lol go for it

didn't want to spend a £500 or a grand getting it sorted, so back on and >63hp so happy with that. Torq all over the place was worse, and where it was likely to cost lots sorting, whereas now its makes everything just a little earlier and holds it for longer

I can live with a couple bhp

Being 10% down last year didn't slow me too much!

(So I'm sure 2bhp won't slow you too much Bradders)

and I was a lot more than 2 BHP down last year, it also did me no harm.

Ruban Xaus said it all, "Today I win or crash".
Worked for me, well most of the time.

I wasent sugesting you were down on power or he was up on power .i thought you guys were talking airboxes . weather to use one or not so my point was you can get good horse power without the air box .

yep understand Kev, could be different if tuning ecu or nemesis v PC too.

Dyno guy said could be done, but its all about air flow, filter used, getting the trade off between whats fairly straight forward versus more complex, and for 1 1/2 hp or whatever it would be a lot more costs and the benefit did stack up.

means I have to rethink the tank - thats the only reason I was removing the airbox - and looking at how Ron's is done I'm still going to see what i can do. Worst case its an extra 2 kilos

but bike in a far better position than last year. Suspension properly done by people who know what they are doing, engine in good nick and within a whisker of power limits. And without too much complexity for me to worry about

Oi, I'm worried my engine about to blow now?! I know it could do with an extra few bhp but I like to keep excuses in the bag so not going to chase the extra ponies just yet!

I knew the suspension was made from solid bits of scaffolding, but that's all sorted now
