Right now my budget is limited. Could you please advise what would be better to do first for the next season – restore the EXUP system or install the Ivan’s kit?
I’ll have to go into the carbs anyway (to clean them).
The EXUP system will cost me about €300 with shipping, while the Ivan’s kit is around €200.
I don’t really want to spend money on both at once. I ride about 80/20 city/highway.

K&n - poor quality materials, dont fit and rattle around. Not what they used to be.
Pipercross -, cheap, poor quality materials, coating on the metal to the filters comes away and works into the engine.
DNA - the tightest fitting filters I've ever witnessed. Mmmm love em.
BMC - Look s*xy and fit well! Downside, Italian and can take forever to arrive and expensive!
I have on occasion had issues fitting filters including K&N, in all cases it wasn't the filter that was the issue but owners butchering or having damaged the standard air box. Or trying to force trumpet filters non standard/standard carbs with insufficient space.
As mentioned earlier, if this was as bad as you're telling us. It would be all over forums including car forums, possibly even mentioned in the motorcycling/car press. I've not seen anything directly stating quality issues, only personal preferences.
I know of a fair few who are heavily into racing in all its forms. Many of those use K&N none have told me there is any issues of fit or quality.
There's the poor quality k&n pod filters.
And then the good quality bmc
Im going to order a dna just to prove a point!
