as title really,do i need an airfilter on my t/b's for its soon to be applied for sva

No

thanks,just trying to minimise cost to make sva.

Just make sure if the TBs stick out of the bonnet that they meed edge radius requirements.

i had no bother with no air filters on my bike carbs for sva 18 months ago. probably better without, so as not going to run a rich mixture on emmisions

If you're driving to the test I wouldn't.... Running without filters lets all kind off small particle size grot into the engine which will act like a fine grinding paste and knacker the engine super quickly.....

If you're trailering it then maybe...

Otherwise I'd try and fit some ASAP...
