I actually don’t think you need to ‘shave’ the rubber inlet at all. The 30 or 32 (can’t remember which) dellorto fitted to tzr’s just has a thinner wall where it fits into the rubber…
Can’t speak for Mikuni though…
You will have to do without it being angled to fit like the 28mm though. Shouldn’t be a problem though. I’ve had 30mm carbs fitted to Vespa’s that were mounted at horrific angles and still worked fine 🙂 We never used to bother with any air filter either, just a bell mouth on the Lambretta’s, maybe…
I know an old hardtail fanatic biker who used to mod z1000’s and other bikes. He told me that RamAir used to make a foam filter kit for flatslide Mikuni carbs, included in it was a ‘jet correction’ kit that was a brass threaded insert for the power valve. You had to drill & tap the existing P/J casted hole and thread in the replacement.
Interesting was that they didn’t recommend changing any other jetting on the carb...
Okay so I think I’ve solved it, if you cut away the tab/loophole that the coolant line at the rear feeds that’s attached to your air box (don’t worry everything still follows it’s original route and looks clean) you can then take off your battery tray and unbolt your air box and remove the whole system air boot included with absolutely 0 effort at all. To refit you simply the procedure in reverse, to fit it it all in you have to approach from the exhaust side and twist
All that’s required is you remove your rear exhaust/silencer, rear quarter panels and seat
I shit you not, what is usually a 45 minute job with lots of profanity is now a piece of piss
@SpookDog it is a a lot of money yes but they are suppose to be so good, look them up online on the reviews they are suppose to make the performance so much better, also takes the stress out of jetting been wrong on traditional carbs Ect, which I think is a pretty common problem on DTs is carb related problems
The whole goal of my project is to build a old school looking two stroke but have a more improved or up to date component structure
I’m pretty sure everything’s on the stock set up on the carb although the pilot screw is at 1 and 1/2 turns out I’m planning on doing a top end rebuild and maybe getting the cylinder wall honed if it needs it but I’m gonna keep the standard 56mm bore also putting some boysen reeds in it to make it a bit more responsive
my mates got a 1988 model with a hand welded pipe from Portugal and with reeds and no snorkel and I think he went Down to 230 main jet and standard on everything else so I’ll keep mine on the 240 and see what’s it’s like after I’ve done it he said the reeds make it a bit richer so may have to go down a few
