    So I tried to install the R6 throttle (2C0-26240-00-00) yesterday, and I can’t get it to work properly. I Shaved down the parts like you are supposed to, but it still doesn’t move freely. And it binds or something when I turn the handle bars to the right. Any tips?

    So I need to get new tires. I’ve looked through a bunch of threads and most of the tires mentioned are out of stock. What is in stock: Pirelli diablo Rosso III, Metzeler Sportec M7 rr, sportec M9 rr. And some cheaper ones like shinkos which don’t really have any reviews so Idk about those. I’m...
  6. Ninja 400 Complaints, Issues And Problems
    I have a 2018 Ninja 400 with just under 3,000 miles. I just changed the oil and flushed the old coolant and replaced it with Engine Ice. After about 15-20 mins of idling the temp gage is all the way up and the red light comes on. I tried squeezing the coolant lines and letting the coolant drain...

    I’m about to order some heavy duty clutch plates cause my clutch is almost burnt. Curious if I should go ahead and replace the steel plates as well? Or do they not wear out as fast. Also, noticed on nortonmotosports they have 2 options for the clutch plates, normal and a ‘track only’ option...

    I noticed this rattling/scraping(?) sound while I was riding earlier, it progresses with the rpms once it passes 6k. Doesn’t really seem like a normal sound. I’m curious if this is the horn or something loose rattling, or part of the engine. Just listen to the video, you may need to wear earbuds...

    Hello all, Around a month ago I purchased my first bike, a 21’ Ninja 400 with ABS. As anyone who gets their first bike they begin to look into upgrades, accessories and the whole nine yards. I’ve learned little by little about ECU flashes, power commanders, sprocket and chain upgrades, quick...

    I have a ZG corsa smoke windscreen for sale. I got it yesterday and looks great. Did a 30min test ride today, but it’s just not what I was looking for. Works great for tall riders, and it looks great on the N400s. No scratches, original packaging. Shipping out of Austin, Texas area. Asking $90...

    ++++++UPDATED: 05/04/2021 - pics added++++++ I thought I would do, what may be helpful for some, a rating of the mods I have done to my Ninja 400. This can help people who are looking at the perspective mods and deciding whether or not they are worth it or beneficial. I will put my former mods...
  16. Kawasaki Ninja 400 Videos
    Not sure if any of you have seen this video, but you can tell this rider was trying to show off to the two guys on the Groms. I saw this video for the first time a day before I picked up my own 2021 Ninja 400 ABS! I feel bad for the Ninja 400, the guy is a tool and deserved what he got IMO...
  17. What did you do to your 2018+ Ninja 400 today?
    After waiting for a fuel rail for nearly 2 weeks, I finally got it in Monday (4/12/21) and put her back together that very day. It is unreal how much of a difference these mods have made to the appearance, and especially, the performance! It pulls harder and has a more sporty feel, sounds...

    I got a Delkevic full exhaust system (13.5" titanium pipe with the stainless headers). I also got a Power Commander V that requires you to take off the fairings, gas tank, and air box. The tank was not easy to get off due to the rubber grommets in the front holding it in pretty strongly. I...
  19. Ninja 400 Complaints, Issues And Problems
    So I’ve been having an issue were the throttle free play increases in higher gears or speeds. Which creates an issue when rev matching and braking hard. It’s not a huge problem but I do want to fix it. I keep the throttle free play pretty tight, but to where it still idles at 1,300 rpm and no...

    Just out of curiosity, has anybody replaced the swing arm with a non oem one? I don’t mean stretched or whatever, just keeping the stock wheelbase or close to it. Also how would a lighter weight or different style swing arm make the bike handle?
