Re: Honda CBR 250R

Lucky guys,
A bad worm has entered my mind!. Clip-on alignment issue:
Since we were discussing handle bar alignment issues - just checked mine. This is what I found.
When I look where the clip-ons are bolted, keeping direction straight, it looks both are aligned. As per post from [MENTION=51754]theironhorse99[/MENTION] to check proper alignment - when I turn handle to extreme right - I see about 2 inch clearance between tank and right piece where as when I turn to extreme left - I see about 2.5 inch clearance between tank and left clip-on piece.

Question time:
Should I venture to align the clip-ons or leave it as it is?. Any side-effects by riding it as it is?. During initial days - I had slight right shoulder discomfort, but went away over time.

Thanks.

Re: Honda CBR 250R


ideally they should be aligned however in short rides it wudn't cause any harm. people who started riding new might have issues or pain etc.. but in long term it might just make you habitual of riding that way. though it can be fixed and the body would again get aligned to new posture.. its your call whether to get it right or leave it as it is...


the only discomfort i found was in city rides that one side of the palm gets numb left/right.. due to uneven presurre.. due to constant clutch and accelerator movement. on highways it might be of major discomfort. but why not just get a 10 rs number 6 allen key and fix it an see how it goes...

you can always go bck to where it was.. make a small mark with the black board chalk peice on old setting and check it out..

Re: Honda CBR 250R

I cannot understand as to how your clip-ons are misaligned in the first place. This is presuming that they are mounted correctly.

Below the clip-ons, you will see a metal plate. At both ends of this plate, clamps grips the left and right fork tube. Where the two opposing sides of each clamp face each other, there is a distinct gap.

A stud from the bottom of the clip-ons slots neatly into this gap. There is barely 1 or at max 1.5 mm of space between the stud and either the forward or rearward part of the clamp's opposing arms so there is virtually no chance of one side at a different angle compared to the other.

Please check the following:

1. Is the stud settled into the aforementioned gap? If yes, then the clip-on rod itself is bent. If no then go to 2 below.

2. After the stud settles into the gap, are the clip-ons aligned? If yes, problem solved. If no, then (a) the clip-on rod is bent and/or (b) the gap is too much and one clip-on is forward of the centre of the gap while the other is towards the rear of the centre of the gap. Loosen the clip-ons and set them BOTH at either the forward or the rearward position.

3. Steps 1 and 2 should solve the issue. If not, you have more serious issues like central spine bent to the right.

Re: Honda CBR 250R

When looking from top, these clip-ons look well aligned. But when twist the handle to extreme left, I see more gap between tank and left handle compared to gap with right handle and tank when handle is to extreme right. This is how I say that clip-ons are not aligned.

Front fork oil and seal change

Since the last couple of days, I had observed that the oil seal in the right fork tube was bust. Took time out in the morning and went to the local ASC, "Five Star Auto Agency", Junagadh.

The agency had a Honda-trained tech sp chap who was, as things turned out, quite knowledgeable about the maintenance issues plaguing the 250 model.

First, oil seal change. The fork was dismantled, front wheel removed etc. Then the chap told me an interesting thing. Se the diagram to understand the explanation:



Part No 13 is "Pipe Seat". This is secured to the bottom of the fork tube by Part No 20 " Socket Bolt". The pipe seat holds the inner tube to the outer tube.

To remove Part No 16 "Seal Set", the socket bolt is loosened, the pipe seat is removed, the fork tube is removed, the kaput seal is removed and then the sub-assembly is re-assembled in a FOLI (First Out Last In) manner.

Now, the Pipe Seat is actually a 1.5 cm Allen bolt. Apparently, for the CBR 250 range, Honda has not supplied the requisite Allen key to remove this bolt to ANY ASC. ASCs have the key for all other bikes including the CBR 150. But not the 250. So, the ASC has to do some "jugaad" by welding a 1.5 cm bolt to a long T bar. This bar now works like an Allen key and is used to grip the Allen bolt type Pipe Seat in place while the socket bolt at the bottom is removed.

This particular ASC had not faced a fork oil seal issue with any 250 till date so the mechanic was kind enough to go into town, obtain a 1.5 cm bolt, get it welded to a T bar and do the job. Hassle one solved.

Hassle No Two. Check the images:



The above is used to fix the oil seal firmly onto its base. The inner ring goes into the base of the outer rammer, the seal is placed on the base, the rammer tool is slipped onto the tube and the seal is literally rammed home.

Here, the inner dia of the inner ring was not enough to allow it to slip onto the tube. Sigh. The whole farking tool was useless. So, we had to do it the old fashioned way - using a wide screwdriver to seat the seal properly.

Hassle No 3. The fork oil cannot be drained through a convenient drain bolt at the bottom of the fork outer tube. The whole tube assembly has to be removed, the end cap unscrewed, the tube tilted upside down and then the oil moves out. Fortunately, the mechanic was aware of this and the oil from from both tubes was replaced before they were fitted back. BTW, the old oil was black with dirt while new one was clear. How did dirt find its way thru a layer of seals is anybody's guess...

Seal + oil for both tubes + labour = Rs 670/- I was surprised to see a 12.5% service tax levied on Labour Charges. Classic double jeopardy

The front suspension is now markedly firmer but more pliant. Preload and rebound damping have both improved drastically, less of the Pogo stick tendency seen earlier.

You have not clarified whether the stud is in the gap or not. Don't look from the top of the clip-on, look at the bottom first (and that is not a naughty comment). Is the stud in the gap???

Re: Honda CBR 250R

Hi Manan,

They have charged you much more (or that's what it seems to me).
They should not charge for chain lubing at all (at least during the free service).
I still don't pay for chain lubing in Haiku Honda or Sapphire, Bangalore (but that is my personal relation with the service staff their).
Also they have charged you more for engine oil as i believe our bikes do not take all 2qty so they pro rate the engine oil charges.
If you have time, call them and tell them about their mistake.
If they dont listen give them the reference of the first service bill of the someone else (one pasted below your post).
Honda tries to provide a good service but these ASC's always spoil the experience with such petty tricks to steal money.
Anyways Silicon does not have a great reputation when it comes to service.
Talk to them as only crying baby gets the milk.

Hope it helps.

Regards
Piyush

Re: Honda CBR 250R

thank you, I always suspected these silicon people. okay I will talk to them. Tell me, of haiku and saffire, which were the showrooms you went to?
Regarding the engine oil, I told them to fill to the limit, assuming one oil has only a liter I told them to fill it to the max.
The chain lubrication? perhaps it was my mistake to tell them that there were rust spots in the chain, other wise it could have been free. at least they used motul
I will try saffire honda central mall jp nagar for my next free service or any paid service.

Noob question, can I renew my insurance at saffire, but I purchased my bike from silicon.

Thanks for pointing the other showrooms out.

Manan.

Edit- talked to them about the bill they kept on spinning me around citing this and that, got really angry at them, but for the sake of maintaining a civil tongue I left them at that. I am not going back to silicon for a considerable period of time.

Edit- anyone knows to whom I can refer the matter to in their hierarchy? a mail address would be preferable.

Re: Front fork oil and seal change

Thanks. Will do in day light and see. By the way, I am beginning to feel that it is not clip-on alignment issue, but rather another strange issue.
The left side fork tube top (I don't know what to call this but - position where left clip on fits to middle handle piece) is about 1.5 inch from the tank when handle is at extreme left.
The right side fork tube top (I don't know what to call this but - position where right clip on fits to middle handle piece) is about 1 inch from the tank when handle is at extreme right.
Any thoughts?, observations?.

Re: Honda CBR 250R

Bro if the bike came with synthetic oil from factory why your ASC replaced it with mineral oil ? See the discription scooter oil ?Also if it is your first service why coolent was changed ?Pls remember to enquire about it & fill up with synthetic oil next time.Also Chain lube if done with O ring lube spray the ASC people charge from 100 to 200,otherwise they use 90w gear oil.

Re: Honda CBR 250R

Its Suryalanka. Its located in Andhra Pradesh

Oh no.. Am not aware of that .. I use Shell in Yamaha as per Shell i thought it to be FS.. Thanks fro ur point, i ll change it once i run 1000kms. and reg coolant some of the coolant got spilled out from the drain valve on the day i was taking the delivery those guys told me its an over flow.. during service that mechanic told i ll top it up as the level is lil low and i said fine go ahead.

Re: Honda CBR 250R


Oh This... I had this problem...

Its really simple.. below the cone, on the triangular component which holds the forks and the cone,
On both sides of it you will find a block of metal which comes in contact with the movable block attached to the forks.
These come in contact when you steer the handle bar to extreme left or right.

The problem is.. That block was worn out.
Remedy.... The ASC will weld a small chess piece over there and your problem will be solved.

Re: Honda CBR 250R

Thanks, that's a relief, worm is almost dead. So, that is the reason that right side handle has bit more rotation than the left for me?. It is hard to believe that part wore out so quickly .
In that case, since it is not a alignment issue - I guess if I leave it as it is, I should be OK? (till right side comes way close to tank).

Re: Honda CBR 250R

Egad, so much of a storm in a teacup. Mmm, right time too, it being the monsoons.

After the oil seal change, my bike is pulling to the left. Not much but enough for it to want to go left when the handle bars are let go of. One headache over, the next one starts. Hangover to hangover, it seems.

Probability One - I have a feeling the rear wheel has move forward on the left side just a wee bit by say 3 or 4 degrees off true thereby causing the pull.

Two - I feel I am ignorant about the sequence of actions to be followed while refitting the fork to the base plate. This may have caused an incorrect alignment of the tubes at the base plate.

Any ideas?

Re: Honda CBR 250R

Went to ASC and asked them y did u fill mineral oil when i repeatedly said fill synthetic oil , those guys are saying they filled synthetic only but the bill shows its the cost of mineral oil. They told me they have filled 2 800ml bottles and so it costed u less. Am not at all convinced. Wat to DO !!
