Re: Honda CBR 250R

Is it a leak from the engine head ? or from the drain bolt nut area or some other place ? Head leaks are mainly caused by busted gaskets, can be solved by replacing the gaskets, for a more permanent fix gasket sealants can be used, but then removing the head for any work can get a bit tough and messy.

For drain bolt area, try changing the drain bolt washer and check if the leak is plugged, if not, might be because of thread slipping and you might have to get some work done there.

Re: Honda CBR 250R

Could be a gasket leak. I face the same problem after my 2nd servicing.

Re: Honda CBR 250R

They've asked for time till Wednesday to arrange the bike, have no choice but to wait.

Re: Honda CBR 250R

no it was changed last time. He said, its all right, we will change next time. They even have it in stock. I dont understand why. Anyways, I will chance it soon. Wont it be a problem, replacing the filter, with engine oil still in the engine? Or they need to drain?

Honda CBR 250R

Oil filter needs to be changed every alternative oil change starting from 1st service. If it was changed last time, u need not get it changed again. Owners manual clearly states so. U can change the oil filter without fully draining the oil by tilting you bike to it's left while changing the filter.

Re: Honda CBR 250R

I think it the drain bolt issue. The cowl below the engine is oiled. No oil on the crankcase though. Will visit svc tommorow.

Re: Honda CBR 250R

Drain bolt leaks are nasty, if a washer change cannot plug it then it gets to be a pain in the arse.

P.s: 3rd free service over, replaced the air filter, oil, oil filter. I had this problem of oil leaking from the dip stick area, because of the oil seal getting damaged, changed that as well..

Now she is done 12k in 6 months, last few months seeing almost very less riding.

You are theoretically correct. But I trust the R&D capabilities of honda. I am sure they would never do anything that would harm the life of an engine. Yes old oil filter does contain used oil and some metal particals , but it is designed in such a way that they don't enter back Into the oil. Now v think of it , there are vehicles without oil filters which are doing well too ! Like the zma.

Re: Honda CBR 250R


Oy, where did my comment go ??


Ok, so here is what i had written for that tag.

I make it a point to replace the oil filter each time because, after 6k kms the filter has done its job it has all the gunk and dust or dirt particles that it has filtered, and also when you do not change the oil filter close to 150ml or so of old oil is also left behind. Now when you pour the new oil in which is to live for another 6k kms, what happens is that the new oil gets mixed up with this old 6k kms oil which is near to 150 ml and it gets contaminated, and now this new oil is to be filtered by the same old oil filter which has done its job nicely for the last 6k kms and has all the gunk and dust particles in them, so basically what happens is when you try to filter the oil, it is actually just getting mixed with the old dust and gunk.

This is why i always insist the svc guys to change the filter each time i change the oil.

Re: Honda CBR 250R

HI

yes sure ZMA has a mesh type 'Filter' but still that also needs to be cleaned periodically. other wise the new oil will need to dissolve the particle on the Mesh filter and new dirt also. on a filter type if not replaced then old filter 1st is oil will get bypassed by the filter and keep collecting dust till it saturates earlier than usual.


Also try a vehicle with old oil filter and new oil see the range and how bike feels to ride, then try the same with new oil and oil filter. there is a big difference in overall performance. the Mechanic is the one telling us no need since it is a easy fix for him/her to complete the days service out put quota.

See the Manual it will state replace place oil and Oil filter for every oil replacement service.

Re: Honda CBR 250R

Just a query from above post. Do you change oil only after 6K or top up at certain intervals.
One FZ guy out here changes engine oil after 4/5K and top up oil after each 1K or so. Is it correct for CBR too ?

Re: Honda CBR 250R

In that case you surely must have got the oil filter screen cleaned, how clogged was it?

Re: Honda CBR 250R

The svc mechs saying no need to replace is a different story, it is less work for them and also stock of spares stays intact. Even about written in the manual, the proper way of doing is this. The filter gets dirty, then it's filtering efficiency is lowered considerably, no the filter is designed not to let the dirt out or not. If you have a filter doing overtime work you know it is bound to get nasty, just take into consideration the water filters materials, would you take the risk of maintaining the same filter just because company says so , or would you change it when you feel it has done enough filtering with the current one and it's efficiency has gone for a toss.

And about vehicles without oil filter , take the pulsars for example, it has a centrifugal oil filter and not exactly a "filter" element, so naturally the manual says nothing about cleaning it, but during periodic services, people who know about it get the clutch assembly area opened and get the filtering area thoroughly cleaned.

Mate, about refilling, it all depends, if you find a small drop in the level of oil you may refill. Depending on the running conditions the fully synthetic oil tends to "disappear" in many cases like heavy traffic riding conditions , so on and so forth. So keeping an eye on the oil level and topping up when necessary is a good thing.

Not sure what you meant by oil filter screen, but let me just take a guess, if it is the oil stained in the drain bolt area, then yes, it was removed and cleaned thoroughly, and so was the whole area of the oil filter, the oil was drained, the filter area was opened, cleaned out, filter replaces, the filter cap seals replaced and filter cap cleaned and new filter dipped in fresh oil and put back in.
I never take chances and never let it get clogged, as i make it a point that all these things are done every 5k kms (Yes, i get it changed every 5k kms.)

Re: Honda CBR 250R

Is there truth to the fact that the red ABS model only comes in the red-silver colour combination? The dealer is telling me that the full red colour is only available in the STD model and that honda only makes the red-silver colour in ABS.

Re: Honda CBR 250R

The honda website lists both abs and non-abs for the full red bike.
