Splitting the cases !

Squeaky back brake? Hard to control at 30mph/40kph?

Hi fella's..... interesting chat.....

Just wanted to ask what oils and how often you changed them..... curious only, not pushing any agenda ;)

I'm deciding what to run in my SDGT from it's 15k km service (currently using 15w50 semi synth Motorex Formula 4T, thinking of going to 15w50 full synth Mx TopSpeed). I don't follow KTM's recommended oil change interval (15k kms for the GT is way to long for my thinking so I change at 5k kms for the semiSyn and will do 7.5k kms if I go fullSyn).

Cheers

Ps My shim buckets in the Blackbird have done 130k kms and look like new - in fact the valve clearances haven't changed, except for the ex valve beside the Cam chain (a typical IL4 trait) which wasn't quite at the change point when I had a new cam chain & tensioner installed at 115k kms..... we put a shim in anyway as the cams were out and now i know not to bother to check them again for the next 50k kms (I'll keep changing the Motul 5100 oil every 6k kms as usual)...... good design - shim buckets in an oil bath! :D..... hope my KTM wears as well as the Honda eh :mrgreen: - lots of bikes have finger followers for high revs/performance, lets hope they don't wear like they did in Hondas in the 80's VF engines.... ;)

Hi Dave

Up until mid last year, I religiously used Cross Power 10W50 every 3500km or every 6 month, what ever was closest. The reason for this is during summer, bike has long periods of not being used and it gets pretty humid and hot this time of the year "Adelaide - the heat wave capital !". When I discovered my bucket problem, I thoguth, fuck it and got the equivalent Ipone Katana oil for under $100. I use 10W50 with Ester because the clutch is the most happy with this oil and the 0.5mm oil jet.

Cheers mate...... i've heard about the clutch oil jet....... it doesn't like too tick an oil. Thankfully no issue with mine so far (and KTM tech is ok with what I'm using though I have wondered if I should run 10w50).

Not much more you can do to preserve those shim buckets (frequent oil changes & good oil) - hope the rebuild was/is successful. I wonder if the rear cyl on your motor might have an oil feed/pressure/heat issue?

Shell Rotella T6, 5w-40. (I read a long winded but convincing article that was floating around for a while on lighter weight oils that highlighted flow over pressure and besides that I like to buck the system) I was doing oil changes every 2.5k mi with oil and filter every 5k mi. I may just do the every 5k mi change, I haven't decided yet. Seems like a waste of time and money to be doing it every 2.5k mi.
The bucket issue appears to be piss poor metallurgy and not wear related.

Yep, rebuild a success, I did 3500km in two months last spring.

The faulty buckets were caused by some c**t at the local KTM dealer using my bike as a parts bin in 2015 when it sat in their workshop for 7 weeks waiting for parts from KTM Australia. How I know this: my bridge bolts were rounded off. No work was ever authorised to lift the cam bridges and bolts don't magically round off :evil:

Cheers mate...... well, as much cheer as you can handle in the extreme heatwave you are about to endure ;)

That's good to know! Pity you probably can't find the guy and get him sacked or made to cover your costs.

At least you have an answer to the mystery, and the lingering doubt has been erased...... you should be good for 100,000 kms now eh 8-)

I've got doubts it was any of the technical staff, but believe it was somebody with access to their workshop after hours. Doesn't matter anyway. This Stealership has a long history of doing dodgey shit and turning it around to be my fault. It was the last straw. So, I didn't waste my time engaging them over this matter. I "burnt the bridges" with a google business review that summarised 20 years of sh*tty experiences with this dealership. Bye bye Kessner Motorcycles.

There is cam damage as a result of the buckets swap. I will monitor. That's why I just said f**k it and started using non approved <$100 oil. My attitude now is this bike only has to last another 2 years. By then, I will have saved up for a Jap bike.
