Re: Honda CBR 250R

Let me post it another way, perhaps you can discern my earlier post in a concise manner. I've clocked more than 12k KMS specifically on 300V on my Pulsar 220, lord knows the can count of 300V in my home. But all the 33k KMS it ran, it has seen oils from different manufacturers, but always the specified grade, until the last oil change which was Mobil Delvac before being sold. 300V is a "wise" choice for those who intend to use it on their engines which are specifically used for racing purposes, where-in the engine oil is meant to last a very short period unlike day-to-day activities. I've always had a strict schedule of draining the 300V in and around 3 to 4k KMS perhaps it was a one-time event when I did a trip to Leh, it extended to 5 to 5.5~ish range. There was a drop in the drained oil level on the 300V but that's an altogether different topic which would unduly extend this post

Well, Sid, I've been patient enough spending close to 7000 Rupees and 12,000 kays, so perhaps yes, I should have been a tad more patient.

Cheers!

Well i guess 220 is the culprit here.. 300V works great only on liquid cooled engines ( All Motul FS ) as far as i have heard. I have seen a guy who made 300V like a melted Tar,after ripping his 220 for some 1000 odd kms and Motul FS generally results in head leak in air cooled engines.( Telling these from what i have seen personally ). So try it on you 390 and you'll love it. 250R loves shell FS i guess, so let shell do the job in 250R. And yes 7100 is equally good if you are a sane rider who love to cruise at average RPM all day.But i didn't get the 300v feel at higher RPM with 7100.

Ps: Am not supporting or telling anything blindly. For the price you pay, it gives you very long drain interval and butter-smooth engine. Only thing it works perfectly only on liquid cooled engines.

Re: Honda CBR 250R

One thing which always bugged me was how bullet riders recommend 300v for their rides. Its even the stock oil for used in most service centres.

Honda CBR 250R

Yup i have no idea on this.. I always thought 300v was for High Revving engines. I was surprised to see people using 300v on bullets that too with positive results. Never seen/met a guy using it. So sorry i don't have any idea how well it works on bullets Stock oil?? I have seen only huge RE made oil drums in service centre with the famous "Gun" quote on it.

Re: Honda CBR 250R

My friend had an Electra. He and his bullet club riders used 300v and so did the company trained mechanic who serviced his bike. Its still a mystery to me.

Off topic, I would like to give a shout out to [MENTION=32286]psr[/MENTION] sir for guiding me today, his advice has been invaluable, and hence proves once again, the success of this forum! Thank you sir!

Re: Honda CBR 250R

I am currently using shell advance ultra fs 10w-40 for past 3-4K kms . though engine is super smooth, but mileage has been dropped from 34kpl to 29kpl ( bike is been used on highways only + almost same gear shift pattern and rpm ) is it because of changing engine oil ? How much mileage you guy's are getting ?

Re: Honda CBR 250R


I used to face the same issue, and I switched to Speed. Mileage has considerably increased to a healthy 32 in the city and about 36 on the highways. This might be an isolated event, but just my two cents.

Re: Honda CBR 250R

i have always got 34kmpl since day one now its 2.5 years plus and 30,000 km + but changing oil never dropped or increased my FE. i would rather suggest using a diffrent fuel bunk.
most of the bunks these days do a lot of crap.

Re: Honda CBR 250R

When was the Last time you checked, and cleaned/replaced your Air Filter ? While many manufacturers had claimed cleaning at 3,000 Kms and replacement at 10~12 K Kms, riding in city spoils the Air Filter badly, and require frequent cleaning at shorter intervals(1,000 Kms) and replacement (6~7K Kms).

Re: Honda CBR 250R

Sir does this apply to the viscous type filter of the CBR too? As per the manual, it is to be replaced every 18000 km. The user manual also mentions not to blow dry the filter as there is risk of damage and reduced efficiency. For this type of filter, what is your recommendation on the cleaning method and frequency?

I finally decided to refresh my bikes look as its been good buddy for long time. This is the first glimpse of it.

Re: Honda CBR 250R

The Viscous Air Filter is a Pleated "Paper" type filter with a sticky coating to trap dust through it's stickiness. Like all Air filters it will gather dust and prevent it from reaching engine. In the case of "Wet" or Sticky filters, the filter is prone to get dirty much more easily. In the Dry Paper type, the dust loading has a chance of falling off the Element on bumpy rides, while the wet element will still hold the dust...in effect the Viscous, wet type filter element is good for filtering dust, but dust loading is cumulative,and so gets dirty sooner than dry type. to clean any Air Filter first tap the filter on ground to loosen up the dust, then blow air ,uniformly, at low pressure From Inside of Air Filter . This will throw the dust clinging to the element and open up pores to make the engine breathe better.
If this is done wrongly.ie., Air being blown at very high pressure , then the Element itself will rupture leading to it's destruction..For this reason it is not advised to blow high pressure air to clean the filter element.
Regarding cleaning interval and Replacement interval, it is governed by the filter element's dust loading...it can happen after 10,000 Kms or 1,000 Kms depending on the environment...So no Hard and Fast rules in this regard. You have to inspect the Air filter Element every 1,000 Kms in moderate dusty condition, and at much lesser Kms in very dusty condition.

Re: Honda CBR 250R

If nothing has changed, then I can only request you to watch the way in which your throttle is opened + the amount of throttle that is opened; to be on safer side do not open more than 70% of the throttle or pls increase the speed upto 100 gradually & then cruise around 110-112 & keep the throttle open just to do that speed & DO NOT open beyond that; your FE should be around 29-30 Kmpl

Air filter has to be changed every 12000 Km per owner's manual & I found with Chennai's weather it has to be changed every 4000-5000 Km. It CANNOT be cleaned to perfection, pls replace.

What does the finished product look like?
