Air Filter Fitted Directly To Carb + Airbox Mods

[SiNX650]

Hi all,

Have read in a few places that these mods help with performance, wondering how they are done properly? (for a Dominator).

Would they affect reliability or servicing?.

Thank you .

I am thinking of altering that enormous air box with aftermarket solution that I would have some space for backup battery, as I am preparing my dommie for long travelling. But still haven't come up with a finished idea.

Answer to Your question would be very simple - all mods _must_ be done properly. That means air intake+carb (jets)+exhaust. All those three components must work in harmony. Increasing air intake without any other proper mods will cause your engine overheating with pricey consequences.

BUT the cheapest mod end up to be buying a more powerful bike

The air filter direct to the carb is called an open or cone filter.

They have the unfortunate side effect of getting wet when it rains and not working anymore, that's why we have airboxes

However, a few tasteful airbox mods and a free flow filter (K&N or similar) can sometimes make an engine breathe a bit better.

BUT as the post above says, the fueling must be checked afterward or it is possible to make things worse and not better.

Airbox or filter mods won't give you any more performance, nothing noticeable anyway. You do that sort of thing to make the bike run better, not to give it more power.

More power on a dommie gets expensive fast, we're talking new exhausts and/or carb, that sort of thing.

If you're looking for KTMlike power, sell the dommie and get a KTM, it's cheaper in the long run.

Thanks for the replies .

The carb needs sorting anyway (bike does the cutting out thing), so thought if there were any mods worth doing might be best to do them at the same time.

I think I've decided not to do anything big, I'm happy with it as it is (it's the first bike I've had over 125cc, so anything would feel like a rocket!).

the very simplest cure is to turn the tickover up slightly using the knurled knob (ooer missus) on the side of the carb

Too late, have ordered a bigger idle jet.

But I like things fixed properly anyway! .

I found that getting it running right at idle meant turning the idle screw so that it just didn't fall out. Now with the #50 jet it's got a bit more margin.

Tweaking the air screw is also a pain though, as it's straight up into the carb, and pretty much unreachable.
