air filter questions - two changes

[swissdean]

Hi, two scoots and two air filter questions:

Lince 125, with casa 185, ancellotti running a 26 m delly with a ramair filter at the mo and for local mot need to show up looking original.

I have a 83 lince so has the kidney shaped airbox and have just invested in a bgm filter for the job...the filter may be ok on its own and lead to no jetting changes etc but just in case what is the approach to drilling an airbox and would it have similar effect as using the ramair do you think?. of note is the lince does not have a air scoop under the seat, just the open round hole. I only want it running roughly ok as I'll probably flip back to the ramair after unless I can get to a point of making no difference

is it best to drill on the side, both sides, back, top, how many holes, what size holes etc..I've googled and see lots of images which all look different in terms of the above questions..advice welcome..just in case i decide to give it a go

li150, rt195, running bgm bigbore and currently 200 manifold and surround MB style panel airfiler on an open mouth 26 mm dellorto. This one has been through the mot as an import with the above casa kit fitted and been ok so far with a ram air. So plan is to fit BGM manifold and switch to ramair...not sure what carb changes i would then likely need to make to suit, if any..anyone running something similar or have any tips?

Thanks as always

The first thing that occurs to me, which may, or may not be right, is that a standard Italian fitting air filter probably won't work in a Spanish kidney airbox. Even if you could attach it to a 26mm carb, which would be awkward.

Why does it have to look original?

I dont think originality is an MOT requirement,if it were the tyres would need to be original and every nut and bolt would need to be as originally fitted.Who knows what was original equipment in the 80s.

The clue is in the name, "swissdean", different country, different rules?

[swissdean]

Yes sorry, MOT or MFK as it here in Switzerland allow no messing with original fittings..so a clubman just about gets through if not too noisy, carb changes are ok as they are not listed, but air filters can be questionable, anything hidden/not visible is fine eg varitronic etc...annoyingly while on my soap box i have even had to frig with the stands to have one wheel off the ground as the rules have a firm' three touch point ' rule and as side stands are not original this can not be applied.

i assumed the Spanish and Italian air filters were the same size..looked it when i took it all off, will have a look this weekend

Oop's,sorry about that,with you saying "mot" I automatically thought that you were in the UK.

As luck would have it I do have a kidney airbox, and as far as I can see there is no way you can fit an Italian filter. As far as I can see the Spanish filter would have to be sealed at one end with a big fat lip to seal it and form a gasket with the elbow.

In fact yer tis....

thanks that'll teach me...so looks like i am now looking at std Spanish filter and therefore must drill hole...so where to drill?

[ToBoldlyGo]

You'll still need a filter, but if you've got the original carb and manifold you could swap them for the MOT maybe? Might be easier, as you've still got the tricky job of connecting the carb to the box and the neck is quite small. And then you'd probably end up altering all your jetting...

If you mean the hole in the toolbox for the filter hose to attach, I think its just a round hole approx. 35-40mm? I removed my toolbox recently to fit a long range tank so could take some pictures at the weekend if you need me to?

Thanks, my lince has the sep kidney shaped airbox not the toolbox type...Ill have a proper look and try this weeked and see what I have and could do, thanks
