im in india and only straight oil recommended is50 for my road king im using straight 50 veedol thats the only straight oil we are getting in india rest its all multi graded as in 20X50 and so on and im really satisfied with this oil hope it does not cause any problem in the future
2) is it good to order a crank position sensor and keep it in spare
3)is there any liquid recommended for my tubeless tyres looking at the roads in india like something thats seals the puncture

 

1) I have no idea,

2) it wouldn't hurt if you think you might damage yours during an oil change, but you probably won't since you already know what it is and how sensitive it can be,

3) look at a product called ride-on. It balances and seals punctures.

Good luck.

 

1-50 weight is Okay especially in a hot climate just give the bike a little warmup time before throttling it hard.
2-ct sensors are quite bullet proof your choice
3-tire plug kit along with any sealer available unless your talking major tire damage.

 

I can barely understand your post but regarding the tires just get this stuff. I should get paid a commission for this. Watch the video.

If the bikes new enough to have a crank sensor you run 20/50 not straight weights and there are a number of good reasons for that including the factory manual says so .

 

Oil viscosity depends on ambient temperatures...

And that's what ALL manuals say. The only reason for a multi-weight oil is if you run in a colder climate. I live in south florida, and ever since the yankees came south with their 'knowledge of oil needs', I've found it harder and harder to get a straight weight oil that is used in our climate.

It's gotten better in the last few years, but I tell you, in the late 80's it was difficult to find the correct straight weight oil because of the northern vacationer's preferences driving product stocked.

 

Im kinda curious what the difference is at full operating temps between 50 weight and 20w50.

 

My understanding of it is that there is NO DIFFERENCE at operating temps. That is not the reason for Multigrade (ie 20w50). it has a lower viscosity at cool temps to enable it to slip around easily in the engine until the operating temps rise....then it acts like 50 weight oil.

Did I get that right?

 

limeyhusker is correct...

 

20W-50 may "act" like SAE50 when hot, but it won't hold up quite as well. But you need not worry about that as long as you change the oil regularly. Cold starts are hardest on an engine, those first couple seconds are torture! That's the whole reason behind multi-grade oil, the easier an oil flows at start up, the faster the engine gets lubricated!
