The Problem With KTM 390 Timing Chain Tensioners.....

[@Boardinfourlife]

Thanks for the video my friend that little pin is exactly what I found lodged in my crankshaft oil port 🥴 unreal..

[@RhoadsChristopher]

Oh wow! Do you mind sending me a photo of it?

[@Boardinfourlife]

@RhoadsChristopher sorry man just threw it out before high grit sanding down the more prone to abration remnants of the conrod bearing off the main crankshaft journal.. that indeed was the culprit tho..

[@finophile]

Again another great presentation. I've got a gen 1 bike with less than 3000km (yes) on it which I acquired from a friend. I have to say after many decades of motorcycles all these issues are just mind boggling. Even my 89 ducati was less problem

[@sluota]

I totaly agree with author, I have upgraded original tensioner to manual and now there is no problem at all

[@robinkarlsson1460]

Nice vid dude, ty. Would it be hard to make a custom pin for this you think? Before breaks

[@RhoadsChristopher]

I've seen what looks like a revision on possibly the new models. I haven't had a chance to fully investigate.

[@vernonhochstetler7608]

How has the 400 KT manual one done for you/ Any issue or things to keep an eye on?

[@RhoadsChristopher]

No issues, but to be fair my bike is down while I change out my water pump seal. Bike seems to run nice and quiet now.

[@vernonhochstetler7608]

@@RhoadsChristopher I only have 4167 miles on my 2021 Duke 390. I have already done 3 oil changes, new plug. new tires, new front 16t sprocket, new rear 45t, BMC air filter, Coober air lid and RB EVO. I am not top of stuff and wanting mod it to last. I am wanting to switch the tensioner out. What else do you suggest to do or keep an eye on. And upgrade the coolant cap to the 1.8 bar flushed all the stock coolant out. Put Engine ice in it. Lots done so far. Any more I should do? Any help would be respectfully appreciated

[@RhoadsChristopher]

@Vernon Hochstetler the biggest thing is to run good oil and do your oil changes on time. The only thing I would consider is the spal fan.

[@khmerghost]

Owh by the way. Are the shim on duke 390 outer diameter is 8.7mm?

[@JH09SUMIT]

I believe they're 10mm on 390, 8.7 on 200s

[@khmerghost]

That is really bad. Could cause a catastrophic failure to your engine thats a big chunk of metal goes missing.

[@khmerghost]

Would be better to modified it using a long screw + nut and threadlock.

[@RhoadsChristopher]

I am not using a manual tensioner

[@khmerghost]

@@RhoadsChristopher no I mean the rubber cap on that tensioner

[@DuzBee]

10:00min in what could have been said in 3min…… just wasting people’s time man, sort it out. ‘Tensions on 390’s break often, take a look here, end of video’…. done!

[@RhoadsChristopher]

Ummmm okay lol.

[@RhoadsChristopher]

I have the following suggestions: 1. Make your own 3:00 minute video covering the topic. Then let me know and I would love to watch it and any other content you make. 2. Don't watch anything else I've made. It is clear you are very to the point and my videos are not something you enjoy. Thanks.

Didn't waste my time
