Yes, got a DL 3 months ago..

Hope to get more info on these required checks by referring to previous pages of this thread.. Thanks..

I had some work doen on my biek today.

I had the stem nut adjusted again....Im yet to properly test it out.

I had the brake master cylinder opened and there was a good bit of dust and crap settled at the bottom. God only knows how it happened since its always sealed. This was probably blocking the 'feeder holes' to the brake hose and Im guessing thats why I was having a squishy brake. I asked the mech to bleed out the brake fluid...but he just filled some new fluid only in the master cylinder, pumped the brake a few times with the valve at the caliper closed. I wanted to give him a piec3 of my mind for not sticking to procedure but I was also curious about the outcome....so i let him go ahead with it. It turns out that my brakes are firm and fine......atleast for the 5-6 km I drove today. And it cost me 15 minutes and rs 22 for fluid and 25 for labour compared to rs 100 for a full bottle of fluid alone. That seems like a good outcome for this experiment....god forbid that i'll have to deal with brake failure in the near future because of this.

I also asked about the recommended fork oil level and according to my mech..."saar its pakka 150 cc according to company specification and ive filled it exactly that much". He offered to remove my fork and show it. I trusted him and declined. But why does my suspension feel stiff and my bike stance taller? the mech claims its perfect to the point of getting angry with my denial. Is there perhaps another setting that needs work?

I remember nads saying that his mech 'andaaj'ed the fork oil level on the gs to be 10 cc more than slingshot. my mech says slingshot fork oil level is 140cc. fortunate coincidence for nads if this is true.

If source of slime/grime in break oil was not from outside, it must be from inside. Any/all the moving parts in Master-Cylinder assembly or the Oil itself!
GS suspension is Coil-Spring and Oil damped.
suspects and analysis:

1. Fork Oil:
If fork oil has worn out then replace it with new one within recommended grades and volume.
- it was about recommended amount 150cc, was it of recommended grade?

2. Coil-Spring:
IMO, major and the only player in recoiling the suspension to its original position.
- since your bike's front has taller stance, we shall assume the spring hasn't lost any of its original properties.

3. Oil Damping:
Damping fluid(Fork oil) moves across one or more orifices to provide additional damping. Smaller orifices restrict the flow of the fork oil more and give greater damping. Heavier the fork-oil higher will be its damping effect.
I'm not sure about this one, however for argument sake there has to be some orifices for the flow.

I think the cause may be one of the below:
- fork oil was not of the recommended grade. I guess it's medium weight 7.5wt or XXw30 grade or about 34 cSt @40'C
- oil damping is not working properly, probably due to misaligned/blocked orifices

If you happen to open the front fork for some reason, please take some pictures and share them with us.

what's the name and grade of the fork oil that was used?

PS:
I'm the guy who once said "switching to heavy Engine-Oil from an lighter one might affect the speed of the bike at any given RPM!" so take me lightly.

A nice article on the subject in discussion:



Excerpt:

^^^^ Thanks for taking the time to trouble shoot. Your explanation makes sense to me. I did ask my mech if there was any sort of valve or some regulating mechanism that could be the culprit in this case. It seems that our suspension doesnt have any such mechanism since there are no adjustments to set preload and damping. I wish I had a copy of the service manual....that'd make things much easier. I'll just open up the fork myself sometime. Only need to buy a proper toolset.

The fork oil is company recommended grade as well according to him. It didnt occur to me to ask him any more details than that. I'll make it a point to ask about this. The oil is yellow in colour is all I can say for now.

Regarding that information about the brakes.....my brake was soft and with inconsistent bite, not hard. Ive read that the brake fluid readily absorbs moisture but I wonder where it comes into contact with moisture in the first place, since its in a sealed environment.

Understanding SparkPlug Nomenclature

I visited SVC @ Value Suzuki Yelahanka B'lore asking for GS's Spark-Plug. To my surprise what I got was Champion Power P-RZ9HC. I was riddled with confusion; Owner's Manual says NGK CPR7HSA as standard model. I returned the plug. At this SVC you'll find female personnel handling spares division, hence there were no ego clashes.

Few days later, I visited SVC @ Saptagiri SVC Rajkumar road B'lore. Head on ego clashes and delays. I even ended up paying for the Spark-Plug without looking at the model. It was again a Champion Power P-RZ9HC. I asked "I want NGK model for my GS150R" with a question mark on my face. Response was "Sir, we give you what company supplies". As it was busy counter, even some of the buyers joined the voice "it's what company supplies". I left the place nodding my head with disapproval.

Today while I was going through my Access's "Owner's Manual" I found out Champion Power P-RZ9HC was the recommended spark plug. In fact after searching over the internet, it was the most common model for many scooters across scooter manufacturers.

Although we can find several substitutes for a given spark-plug across manufacturers, we'll never be certain of operating quality.

Attached herewith some nomenclature files. Guess, they're not complete.

Pop that plug in, compare performance with ngk and let us know. Im guessing that if there is a difference, it will be hard to discern. Champion is a well known company....so, there isnt much to be bothered about quality.

On a separate note, NGK, on their USA website, claims that all their plugs, regardless of application, adhere to the same standard of manufacture according to some company internal policy.....dont know how true this is for those manufactured here.

Are there any parallels to our plug from bosch?

Does the heat range have a common measure between companies? If so, then you've been given a colder plug than recommended.

Spark Plug NGK or Champion

Hello,

If it comes to sparkplug NGK is world known brand, and its quality is good.

Wait

But that doesn't mean Champion is bad, champion is also equally good.

Many brands in india (not only indlan brands) uses champion spark (and recommend too) for their bikes.

Earlier in my splendor herohonda recommends and used champion plugs.

My splendor bike (now sold out) was more than 1 lakhs kms old and I changed spark plug only thrice, do I need to mention the spark plug I used was champion.

For daily commuting purpose these two spark plugs doest show any major diffrence in bikes performance or mileage.

Going by the heat cross reference chart attached herewith, Heat number ought have been 7 or 8. 9 per champion is a hotter one. I'm surprised that Access125 has hotter operating range!

We don't have sufficient and effective measuring devices to draw thin lines between the performances of Champion Power P-RZ9HC and NGK CPR7HSA. I've mileage as reference, measuring at different consistent RPMs will be tedious and time consuming compared to invested amount, ₹ 74/-(and mileage loss/gain). For now, I'll go with both deliver same performance and mileage at different operating conditions.

I couldn't locate any Bosch nomenclature chart; however I guess W and 5 will be present in the part number equivalent to NGK CPR7HSA.

Access 125 runs NGK CR6HSA as per stock factory settings.............6 is in cooler range.

Yes, both NGK CR6HSA and Champion P-RZ9HC are recommended spark plugs for Access125.

Going by the heat cross reference chart attached earlier, in NGK smaller the number hotter the operating heat-range.

Can somebody share the price of NGK CPR7HSA (GS's plug)? Also the most likely place where I can get it!
Inquiry at few SVCs turned out futile.

got my new gs150r 2012 model

Hi all got the bike delivered last saturday. bike is great. very smooth, no vibrations at all . need to wait till the run in time.
engine's sound while accelerating is superb.

enjoy riding and welcome home,

post some pictures of your gs

sorry for the OT guys...

wow!!It took me almost 3 years to realize that i stay a km away from Joel's garage..Immediately after i got to knw the address,picked up my bike's key and ripped to his place.. The sight of those exhausts,roaring r15 and pimped rtr's gave me multiple orgasms..
I couldn't believe what i was seeing..

For those who doesn't know about Joel.check this out http://www.xbhp.com/talkies/pit-stop...rformance.html
