Sprint Sprint 900 Airbox Or Cones ?

My previous experience of fitting K&N type individual cone type filters reaches back to the early 90’s, it’s just a pity that my memory doesn’t What I do remember though is that in order to get them to run anything like standard there was quite a bit of work involving stripping the carbs down and fitting different jets, air screws and the like so you may find that your carbs don’t have the correct jets etc for the stock airbox. They never ran as good as stock just gave a more noisy intake sound and if the bike was left out in the rain and the filters got wet they ran like shit.

 

It sounds to me like the fitting of the cone filters was an expedient move, perhaps because for quite some time until recently the standard airbox for T300 models was unobtainable. If it's not running very well it could be that the jetting hasn't been changed to match the freer flowing cone filters?

The genuine, standard airbox IS now available, though it isn't cheap (£61.44 from FOWLERS) and, IMHO looks better and is likely to perform better ..... assuming you are running standard jetting.

I haven't removed an airbox for a long time but I don't recall ever having to remove the carbs to get the box off - it's a right, royal PITA to get the box off but, my spectacularly flawed memory seems to recall it being awkward and difficult, not impossible. It just needs a lot of pulling, tugging, shuffling and swearing ...... and skinned knuckles.

It was - perhaps still is - a common mod. to unscrew and separate the original airbox halves (the originals were made as 'sealed' units but were screwed together) and replace the internal filter with a K&N unit which could be cleaned and re-oiled, unlike the original paper element. This didn't really mean any less difficulty in the servicing, it just meant that you weren't paying a small fortune for the plastic housing every time the filter was due for removal.

The T300s, when fuelling correctly, run very well indeed on the stock set up - I'd be inclined to return to standard and be prepared for a little extra effort every couple of years to replace the airbox.

 

You are doing the right thing by going back to standard. Triumph spent a load of money to get the fuelling right and many have tried and failed to do the same with pods. I believe that the crt kit works well tho.
