Thread: *+%#@%$ air filter assembly


Started 3 years, 6 months ago by Motor31
I did a small job again today and learned once again how much of a pain in the butt it is to do something as simple as changing an airfilter on a K75RT. I would really LOVE to meet the teutonic twit who designed the airfilter assembly. I wanna meet him in a dark alley with a 2x4. The one good thing is that I saw the crankcase vent line was oily and leaking. Of course like usual I ...

You know how those teutonic twits designed the K-bikes right?? They took a string from which they suspended the airfilter, then proceeded to built the bike around it. .....

Mine just sort of slides and wiggles out to the right while I hold the top cover up. My biggest fuss is reinstalling the left rear lid clip. I ended up with a really long, long nose pliers.

Did you take the right kneepad (between the fairing and gas tank) off to do the job? It should not be that hard compared to other K75's.

I took off the entire right side of the fairing off. You have to to get access to it. I have an RT. The hassle was that it was very hard to ...

I put a K & N filter kit on both my bikes long ago (over 150,000 miles) for the very reason that it is soooo much easier maintain. One screw, pop it off, clean, oil, replace. I've heard a lot of negative comments about K & N filters but I have not experienced any problems after making the switch. It also opens up the area above the engine and helps move the hot air out. The kit consists of one...

Looks really nice. What is the flat metal base for? I had negative results in the desert with K&N, but I also remember when street bikes came without filters. I wonder if a fine foam overwrap would help the K&N. It looks more like a motorcycle with the K&N.

That is an idea I Gotta Steal! I'd just want to add a cowling from in front of the radiator side coverpoint to rainproof (hat tip > jdiaz) and decorate/conceal the entire assembly. 41077...Salute! I wonder how that affects fuel/air ratio... My R11HR has K&Ns at the venturis of each injector intake. An exhaust gas analyzer showed 18-21(!):1 where 14.7:1 is optimal & mid-high 13s is ...

Silk 100........ I hate you! I did see that when I was looking at oilhead RT's. It's one of the reasons I was / am seriously considering them for a replacement for the K75. I just have to find an 04 that I can afford. It may take a couple years or decades though......

I suspect a lot of filter element replacements are premature. I connect a Filter Minder and do a full throttle run through the gears every so often to check.

Looks like there might be a second bolt back by the fuel pressure regulator, to secure the plate a little better and maybe give the bracket a little stronger platform to sit on. But if that plate were out of there, you sure could keep food nice and...

Question, I want to know what happens in a hard rain. __________________ Jon Diaz I pull over and wait, seriously we were surfing with the semi's one time and the wheel wash soaked us, but had no effect on the bikes performance.

Sounds as about as much fun as replacing the airfilter on the RS/GT/LT K's....remove both right and left fairing, front cowling, unbolt fuel tank, disconnect quick connect fuel lines and pray they don't decide to spring a leak, THEN from the bowels of the bike, remove the filter cover, pull the old filter, hoping the pound of insects on it an entomologist would die for don't fall down the throat before you can vaccum out. The...
