Update :: 46000 kms. Took about 29 months to clock 18000 kms from the purchase (@ 28K kms). Minimal rides in the last 8 months.

The CBR will be getting new tyres as the old ones are almost on the last legs. The braking is a little softer + there is uneven wear on the tyres (like zig zag). Not sure whats causing the issue.

The rear brakes are a little jammed as well making the tyres rotate less freely. The headlight switch has a loose connection too.

Did some shopping for the bike! It should go for an overhaul next week. Planning to get it dismantled completely and clean it off the rust and dust. The open parking is causing a lot of nuisance.

Oh lovely, I was waiting for some one with a CBR to express their first hand review of the LiquiMoly products! Awaiting yours!

Falls in the perfect timeline, I'm running on Shell Rimula R4 which will nicely flush the engine before I put in a synthetic oil. I wanted to try something new other than the Shell Advanced Ultra! Looking forward!

I believe some of the products are for your four wheeler too?

Yes he has a Ford Fiesta for which the 5w30 is.

Don't fill truck specific oil like Rimula in a bike. None of them have the JASO MA/MA2 standards that a bike requires.

You don't need to flush your engine unless it is clogged with soot and oil deposits. Once you have completely drained the old engine oil, fill the new one in, and make sure the rating matches what your manual specifies, beyond that you can pick whatever fancy brand, Liqui Moly, Amsoil etc, or just plain old Mak / Servo type, that matches whatever rating and weight your manual specifies.

And @Ratish - you probably need to rotate / balance the tyres on your bike the same way as on your car, given the uneven wear.

Yes, a Fiesta D.

Yeah! Plus, I have ordered new wheel bearing as well, incase!

Plenty of options; Indian Oil 10W30, Motul 7100 10W40, Castrol 10W40, Wurth 5W40. Basically every leading manufacturer caters to the need.

I did not understand this. How do you rotate tyres on a modern bike which has totally different sizes (and tread) front and back?

Cheers, Doc

Sir, this oil is tried and tested on the CBR by many, and there are pages of discussions which prove that this oil acts as an ultimate flush plus adds the ZDDP layers on the engine internals which are abundant in this oil.

Even I have used this oil some cycles ago, and I do this Rimula cycle once in a year for some ~1500 KMs and then switch over to the synthetic oils.

People have used this oil for 10x the KMs I'm using it for.

Sorry @swiftandfurious for hijacking this thread for a different topic!

Awaiting your LiquiMoly review!

Sure, but its going to have to wait a little bit..coz this goes in first . Been reading about this and wanted to try out once for about 1000kms. As luck would have it, a Chennai - Bangalore ride is coming up over the weekend.



The bike's at Motodynamics as of today and it's getting dismantled for a good clean up.



The oil drain. Seems not all that bad as the running was minimal during the last 1 year.



This one or an LED will go into the headlight.



Few other items thats changing:

1. Oil filter
2. Strobe replacement - old one broke off
3. Front & back wheel bearings
4. Air filter
5. LED pilot lamps
6. Tyres
7. Side stand
8. Rusted nuts and bolts - as many as available.
9. Painting the aux light frame - lots of rust

Few things that have to wait

1. Meter cover - will be getting via Karthik, Highlander during my weekend trip
2. Brake pads - both front and back may need a replacement in the next 1000 kms
3. LiquiMoly oil

If your engine needed zinc additives (not to mention mineral oil) I am sure Honda would have been very glad to specify it. Pages of discussion on biker forums are one thing, what Honda specifies after extensive testing is another thing altogether.

Lovely, please share the odometer readings before and after the Rimula oil change, when that happens.

Dear Sir, I'm a fairly new experimenter in this regard, and hence someone like ashwinprakas or aargee or Vijay Anand Sir will probably tell you how much this oil has been tried and tested in various automobiles. While I understand the general notion of straying away from OEM Engine Oil specifications, not a SINGLE negative review or a blown/seized engine has taken place because of the R4. From my limited knowledge, it primarily acts as a flush, and a very mild one at that.

Hence I'm only using it for 1000-1500 KMs. As long as the engine is well lubricated, the very basic principle, I think the Honda should be fine, afterall it's over engineered.

@swiftnfurious, sorry for the OT.

.

The odo is at 46,xxx now. A to & fro Chennai-Bangalore trip will add about 1000 kms. As soon as I hit 1K kms, the plan is to replace Rimula with LiquiMoly.

Even the Motodynamics guys feel the suspension is smooth and are wondering whether its the tyres or the bearing. The wheel bearings are being replaced for both wheels today / tomorrow.

Boss, the origin of this topic is from a very very senior expert & also happened to be a very close friend of mine who experimented & have measured the outcome (although I remain unconvinced)

There's a whole lot of discussion regarding this on xBhp in CBR 250R ownership thread where many owners across India have tried, tested & have provided a positive feedback over last 5+ years.

Here’s why I’m not convinced

There’s a statement about zddp levels - a zinc friction modifier. That spec is in Shell Rotella which is their premium range of diesel oil and not in Rimula which is a regular mineral oil.

Most friction modifiers aren’t a very good idea for motorcycles anyway and Diesel engine oils often don’t contain very much of those. Friction modifiers plus a wet clutch = trouble.

The initially heavier weight of the diesel specific oil might prevent smoking (which seems to be a favourite complaint among cbr owners). However diesel specific oil will shear and get thin at high engine heat. You’ll find yourself doing very frequent oil changes.

Besides diesel oils with an api c* rating (ch4 or ci4 for Rimula) are for compression based engines - diesels. The api s* spec (sm/sn) are for spark engines - petrol ones. While there might be some base level of support for api s* standards in a dedicated diesel specific oil it is generally not a good idea.
