After they sell a new bike they switch over to synthetic on the first oil change. I recently bought a secondhand 2013 690 Duke which had done 4000km. It had it's first service at 1000km and the next isn't required until 7500km. This seems a bit long between oil changes to me. On all my other bikes I usually service them once between the recommended service intervals, (every 4 - 5000km). The KTM gives you bigger power, better brakes, and a more sporting suspension. However, that performance comes at a price. With an MSRP of $3,999, the Honda is exactly a grand shy of the 390 Duke’s $4,999 price tag. If you are a new rider concerned more about price than performance, the Honda may be more your speed. Remove the inspection plug from the clutch cover. A cheaper alternative ($1.00), would be to go to the hardware store and buy a bolt with a 14mm head on it, and 2 nuts that fit the bolt. Spin both nuts on to the bolt, and lock them together. Now insert the 14mm head of the bolt into the inspection plug. At first I was able to make the 690 forks close to the same by simply removing some shims to match closely the EXC. However there is a big difference in how the large chamber and small chamber works. I just gave up and installed the large chamber exc forks and use them very happily. Also I have .48 springs in the EXC. I had the stock .52 in the 424 posts · Joined 2017. #3 · Feb 1, 2018. Goodlife said: Hello fellow Duke enthusiasts, I am a prospective buyer of a Brand new 2017 Duke 690 off the show room floor. I love the bike, I'll buy it now, but I have one hang up, oil consumption. I've read a bit about others experiences with the 690 and it seems to be a coin toss, some have oil In this video I show you how I change the oil in my KTM. I also install a pro shift kit to eliminate false neutrals and improve shifter feel. My bike: 2015 KTM Duke 690 Instagram: Summary of Contents for KTM 690 Duke EU 2012.

(Mineral = dinosaur juice) Dot 3,4,5.1 brake fluid is corrosive and can damage paint, but is less prone to absorb moisture. The slave and master cylinder seals are usually built to suit what ever This must be a year issue, so let's be a little bit more detail oriented in answering (and asking I guess) questions. The cover of my 2018 690 Duke says to use DOT 4 or 5.1 only; Pg 109 of the manual, "Checking/correcting the fluid level of the hydraulic clutch" reads, in part: Warning skin irritation Brake fluid causes skin irritation; blah blah brake fluid; more blah, brake fluid; etc etc Fkjjiwd.
