Re: Honda CBR 250R

Guys i did unbelievably stupid during my last DIY oil and oil filter change.

I had forgot to put drainbolt washer back after draining the oil and now by bike has been running without drain bolt washer (only drain bolt is tightened in oil sump) since last 15 days. There has been no oil leaks though.
Should i drain the oil again and put back drain washer? Or should i wait till next oil change?

The crush washer must be installed, as they form a perfect seal between the crankcase the bolt face. Now that we don't have a leak, which is positive. With the engine totally cold, ask someone to tilt the bike towards themselves to the max lean position they can. Now, remove the drain bolt very slowly and the moment the bolt is about to come loose, immediately block it with your finger. Now, with the crush washer installed on the bolt, slowly remove your plugged finger and simultaneously start screwing in the bolt, you're all set. The leak, if done right should be extremely minimal. If one is apprehensive, he can top up a few ML for the lost ML.

Disclaimer: This should be done on a cold engine, and the above method doesn't infer user induced error and henceforth advises caution.

Cheers!

Re: Honda CBR 250R

Changed tyre set on last Saturday and from the time it was fitted something is blocking the rear wheel to freely move. I showed it to a local mech and he said chain is causing the problem and made some minor adjustment, but prior changing the tyre it was not there. I tried to lift the rear and move the wheel but didn't understand what's the problem, the only thing which I found was that nuts for both sides of the chain were loose.

The orange part nuts were loose at both side and green part was not in proper place. I am due for a service centre visit and change the chain-sprocket, but just wanted to know what could be the reason for it?

Did you check the wheel alignment post fitting the tyre? I am surprised that the tyre change was done outside the SVC, of all the things that can happen a simple misalignment can cause the tyre to jam up, at the worst the axel and bearings are bust.

No, fitting was done from tyre vendor. No alignment, will check it on my next service.

What do you mean by no alignment? is the tyre not at all aligned? do not wait for the next service take it as soon as possible.

No no, I meant at tyre shop they just fitted the tyre that's it! Yes I'm not using the bike right now and taking it to SVC on Friday or Saturday.

About the front suspension oil... I found this thread https://www.bcmtouring.com/forums/th....32743/page-93 which quoted to use the 20W Motul at 350 ml mark. The default I guess is 15W 331 ml (according to the manual, thanks for uploading!)

I was wondering if someone had done the same here and what were the results...

hehe thats my post on bcmtouring ages back

331ml is stock yes but i have been using 350 ml since 4 years and its doing good. get motul or castrol

the tyes has not been fit properly on the axle and due to that chain adjustment has gone bad.. the nuts on both ends might not be at same distance hence will cause issues like bearing dyeing soon and also chain might run very tight or loose and will accelerate chain-sprocket wear and tear.

Hi guys,

I've been following this thread for quite sometime. Quite helpful I must say. I've a CBR which is about to hit 80k kms. Have done K2K, Ladakh and numerous shorter tours. It has kept me amazingly happy. Apart from the routine perishable part replacements... hasn't given me a lot of problems.

I'm currently in Chennai

I had a fall and most of the damage was taken by the left clip-on, but since then the bike's balance and front suspension have been funny(heavier when turning left than right). Few weeks ago, a local technician diagnosed and fixed a minor bend in Triple Tree that fixed the balancing to some extent.

But, now... the front forks make a "thud" noise under sudden changes (hard braking, steep speedbumps) ... similar to what my rear spring did in Ladakh (had to be replaced).

So, needed some advice as to what exactly might be the problem... the springs/oil/the enclosing hardware. Moreover, I was thinking of putting in a heavier grade forkoil (Motul 20W mostly)... read somewhere in this thread that it helps with the squishy front. Any thoughts on the matter will be appreciated.

TIA!

its your front wheel bearing 90 percent done with its life, 10 percent its coneset..
if your last bearing and coneset change was done 25-30k km from current odo. get both changed. they are done for their life.

for front bearings you can get OEM ones for 70 bucks. if you want better quality get NBC else SKF - bearing number 6302.
also change fork oil.

that thud can be just a loose coneset too.

I'm due for a chain-sprocket change, fork oil replace and general service checkups. The problem is I am fed up with Honda ASVC as the CBR mech is too busy and not available on weekends due to high volume work outside city. And for the other ASVC guys in the city, I am not that confident or you might say I do not know them.

I have sourced a local garage who handles 200cc+ bikes and local people are quite happy with them. Now when I asked them to fix this wheel blockage problem, they showed the confidence but that didn't reflect in their work. I bought the chain-sprocket, handle bar ball racers, fork oil and fork seals to be replaced. Should I opt for that local mechanic and do the service from them or wait for the Honda mech to be free? Right now not using the bike from last 3 days due to this wheel moving issue.

In last 4.5 years I never serviced the bike from locals apart from minor adjustments like chain tight and engine oil change, now the big service is here, i.e. fork oil change, chain change and all. What's your opinion guys?

Why in good sense did you even give the bike to local guys in the first place? even at oil changes, the oil strainer is supposed to be cleaned. The manual clearly states what are the things that are user servicable and which are not , now if the Honda guys messed things up you still have a way of taking action against them, not these local guys.

Considering how serious the damage can be and the things that are supposd to be replaced, go to the official service centres.

Re: Honda CBR 250R

Due for a service this week, last time when I visited SVC, mechanic told me to change the spark plug, but I said him what manual says. Bike has done 26k kms in 4.5 years. There is no point of replacing it, but is there any necessity to open it and clean it? Also for engine smoothness anything needs to be taken care? Oil has changed just 2k kms ago.

Did you change the chain kit? How much was the labor outside?

No, all will be done in this service and will update here. Couldn't manage to convince myself to service it from outside as it will be one of the most major service till date.

Well, the authorized dealer managed to screw up my cbr's spark plug replacement, to the end result that I had to tow the vehicle back to the SVC as the improperly fixed plug started vibrating at 5k rpm and finally disintegrated into pieces inside the engine. Don't ask them to clean it unless you personally know the mechanic, they probably will muck it up more.

Just before signing the job slip after the work is done, inspect the engine oil level, check if the fairings are fixed, and take a small test ride with the mechanic.

That's a fear. Yesterday watching Youtube channel Fakira and his chain was messed by Benelli Kolkata ASVC guys. Those guys tightened the chain so much that it broken off in the middle of highway.

BTW, did you serviced your bike from any local mechanics? This is my first time and I am still in a dilemma. Waiting for the CBR service guy to be available from last couple of weeks, but still I'm dialing SVC number and he is not there.
