5w40 ?

Hi!
Made on oil change on my 950 yesterday and the only full-synthetic oil I could get was Motul 5W40.
It seems like my clutch does not work as well as before. On the bumpy road here the gear sometimes jumped out (might have happened before as well?).
I hate to replace this very expensive oil after only a few km`s but do not want to risk that I eat up my clutch further south as it gets hotter...
Any suggestions?
There is a shop here who has 20W50 semisynthetic and 10W40 synthetic if I remenber correctly.
Of course I could ride to Guate and search in other shops than Canella...

Your fine using Motul 5w-40 oil, I've noticed different brands of oils of the same weight can make the bike shift different. On your next oil change try a different brand or for warmer climates a thicker oil. I've had good luck running Rotella T6 5w-40.

So, you mean I can run it as it is? No concerns regarding heat and clutch?

The manual states weights are 5w-40 in lower temps and in higher temps 10w-50.

If it's cooler where you are run 5w-40. If it's hotter out run the 10w-40 and it'll be fine.

Regarding the clutch, it will be fine to run either as long as the oil is for motorcycles and has the JASO MA certification. You can find this certification label on the back of the bottle. The JASO MA certification is specifically for wet clutch operation.

However, yes, you might feel a bit of difference in the clutch operation when switching oil weights. Not to worry though. Normal.

Do not run the heavier 20w oil. It's ok to go a bit lighter but going heavier in oil weight can cause problems. The engine parts need to move. Going too heavy to the 20w could restrict engine parts movement more than what the KTM engineers intended. This engine was designed around a certain oil weight.

It is definately warm here and will get hotter. I am in Guatemala heading towards Panama. The guys here use 20W50. Someone said even as a semi-synthetic would be fine.

norschweger, where in Guate are you?, we are in Xela and will be here for another two weeks studying Spanish, two weeks in I am up to Spinglish so half way there.

We could not get syn oil except for 5-30 at our last change so we are using mobil 20 -50 4T dino oil, the engine is quieter than with synthetic!!!!???

Engine temps are no different and I am very happy having 50wt oil in for the heat, will change this at 5k tho not 7500 like with syn and this will work out perfectly when we do valves etc.

semi-spinglish, no? No fumar espanol? : ) Nice to hear from you again!
I am in Antigua!
I am really undecided what to do. Feels not right to throw away 742Q and 3 hours. But I really do not want to fuck up my clutch. The one ride I did from Guate C. to Antigua (about 60km) I had the feeling that it is more sensitive to start.

Yeah that is a bugga but you should be sweet running it, just try and avoiding lugging it which is sometime bloody hard to do and couple with heat .... I am hearing ya.

We will be in Antigua in two weekends time.

Has Taz not got the right stuff?

It is called 300 V. I do not see a JASO MA on the back but it is for mc`s and it even says that it guarantees the perfect function of a wet clutch. BUT: what about the temperature? Is it that big of a deal?

Who is TAZ?
I will ride 2 up for a week. I do not have to ride a lot and I can take it easy. Otherwise I have sent a package to friends in the States, 8kg less : )

Yeah 300V is good oil. Motul makes great oil. It'll work great. It'll work fine in the heat.

Funny, I have met Taz and talked about oil and stuff but we did not introduce ourselves. : ) Found him cause I was looking for a helmet to borrow. Nice guy. even had dinner with him and his girl today and the first beer since a while. Even had to try the rum from Honduras (?)...: )
Oil stays for a week, than I decide if I change. Do not think so...
Thanks for all replies!
