Re: Suzuki GS150R

But, you didn't tell me if it's a free flow in reverse direction.
Yes, the middle. This is how famous people fumble while trying to display their panache. I guess he intended for a `Happy Sign`.

- We did alright with brake fluid bleeding. Note I mentioned earlier, bite was lacking after cleaning/lubing front disk setup. It remained same after bleeding.

I can guess:
- There is air inside brake hose which didn't budge during bleeding. We did see bubbles coming out & we made sure to pump it till there were no bubbles.
- bite will be back after couple of days.

Will check it today & update.

Re: Suzuki GS150R : Front Disk Check/Clean/Lube : Periodic Maintenance

By Ordinary grease i mean castrol wheel bearing grease. It can withstand high temperature. But i do feel a slight pressure on the front wheels from the brake after releasing the lever. Thanks for the tip.

Re: Suzuki GS150R

When new brake rotors have very fine cutting marks(as shown in the picture) on them as a result of Honing. So the "bite" will be more. After riding few KMs the surface polishes out, and brakes feel less "bite"er. In my case i don't feel the sudden stopping power like when it was new.

Suzuki GS150R : Adjusting Rear Suspension

In the above photo, marks on that disc seems to have been generated by a rotatory honing machine. I believe for maximum contact friction between brake pads & disc we need circular grooves; similar to erstwhile vinyl records.

Bite was good today, I'm satisfied with it. The repeating kat-kat sound from cone set & thumps felt on my palms are reminding me of remaining DIYs.

For better disc braking, I think:
1. surface of the disc has to be oil-free of any kind, so don't even touch it with your hands let alone some waste cloth.
2. groves on disc have to come in sync with brake pads(rough surface).
3. there are no air pockets inside brake hose; which is hard to test.
4. other parts in brake assembly are in optimal condition. i.e. hose, brake fluid, calipers movement etc...

That kindles another question:
Do we have to lube cup pistons?


Adjusting Rear Suspension:
Rear suspension has lost its smoothness after 3yrs of operation. Riding on proper tarmac is alright but it's the rough road that are bothersome. So, I adjusted it to loose setting 5, the last available option. You can do that with your bare hands by twisting to desire setting or by gently tapping on teeth that are marked below:


Make sure setting on both sides is matching; i.e. anyone of the levels 1, 2, 3, 4 & 5.

How long does GS's stock rear suspension really last?

Re: Suzuki GS150R : Adjusting Rear Suspension

I heard GS150R's rear suspension is prone to early damage.

I mailed Suzuki about the charging of head gasket replacement and i received a call from the service manager saying that he can refund the extra money they charged. So i got Rs.350 back. The bad news is i think the head gasket leak is still there.

Re: Suzuki GS150R : Adjusting Rear Suspension

Real bad news is, such incidents further distances customers & SVCs. Which is really a bad development, like a vicious cycle.

Can't comment on Head-Gasket & Rear suspension at the moment.

By ordinary grease I mean all petroleum greases including that lithium based bearing grease. Do not apply any grease other than the synthetic (silicon based) grease suitable for caliper pins. Other greases damage the rubber caliper boots - at least.

It is not necessary. Just be sure that the caliper moves easily by lubricating the pins. If ever you decide to lube it, use nothing other than the type of grease you already applied on the pins and, that too, meagerly.

The gap between the disk and pad is less than 1 mm.

That suspension adjustment makes it very soft and it bottoms out at all humps and ditches especially if you are not so light.

If you feel the ride very harsh, check the tire inflation too.
There is a clamp wrench in our tool kit to adjust suspension.


Mine is 38,200 kms old, ridden through rough village roads and smooth highways. Still in good condition. Lucky me!
Glad to hear that they have refunded that amount. Actually you deserved a refund of, at least, Rs. 450/-.

Re: Suzuki GS150R : Adjusting Rear Suspension

Tire pressure is alright, it just that I followed(tailed) couple of white GS150Rs lately & found rear suspension is action. Let me ride in loose setting for while.

My tool kit is at my native.

Is it free flow in reverse direction for brake fluid?

Re: Suzuki GS150R : Adjusting Rear Suspension

The brake fluid moves freely between the master cylinder and brake bleeding nut if the brake lever is not pressed.
Here is an animation showing how it works.

Re: Suzuki GS150R : Adjusting Rear Suspension

Guys which is the best engine oil for gs150r?

Re: Suzuki GS150R : Adjusting Rear Suspension

Most of the workshops use bearing grease to lube. caliper pins. They don't melt or damage rubber boots, but because it is of higher viscosity the caliper movement will be slower.

Do you have any statistics for the rear suspension damage that occurs on GS150R? or how many GS Owners do you know?. Do you think every GS owner who visit this thread reports every problem they face on their bike?. I have seen people complaint about not receiving their spare rear sturts from the company after their bikes rear suspension got damaged. The service manager himself told me GS150R's rear suspension might damage early, but the front suspension can last more than 1,00,000KMs. I think he might have a point because, considering the softness it provides the gas sturts have to work overtime compared to other bikes and may get damaged early. Now think who has got illusions and hallucinations.
The charge for replacing gasket is Rs. 400 +12.36% taxes and gasket costs RS. 91. So total charge becomes 550.
I deserve Rs. 450 if you consider the petrol charges for getting there.

Are you out of your mind? How do you think these million of cars and bikes get serviced at the service center?
They changed the gasket in front of me.

Sometimes i also follows some bikes and see how well it works.
In good workshops they use bleeding machine to bleed the braking system. The machine supplies the pressurized fluid to the reservoir and you only have open the nipple at the slave cylinder. The fluid flows directly to the slave cylinder from master if no pedal is applied.

Re: Suzuki GS150R : Adjusting Rear Suspension

Any JASO MA2 certified Engine Oil, preferably in below order.

1. 20w40
2. 15w40
3. 10w40

---- Overboard
4. 15w50
5. 20w50


And choose Mineral, Semi-Synth or Fully-Synth based on how deep your pocket is.

You got ₹ 350/- back man, nothing short of an achievement. He was speaking from his experience and nothing else.

Thanks to this site esp punarvasu, I'm taking care of my GS.

Take pictures of your DIYs and share, however crappy the photos may be.

share & prosper.

Re: Suzuki GS150R : Adjusting Rear Suspension

Any 20w-40 mineral or xxW40 semi synthetic or fully synthetic is enough.

They are more experienced and their practices cannot be questioned. But I don’t believe everything the mechanics do are correct and trustable. Otherwise, how did they dare to lube the caliper pins with lithium based grease and tell you that its viscosity is hindering free movement where free movement is essential?
[QUOTE=dip097;1058763] They don't melt or damage rubber boots, but because it is of higher viscosity the caliper movement will be slower. [QUOTE]
Let it be true.
And the higher viscosity may be causing the slow movement as you said though what I have heard about it is different.

I am guessing everything. The actual figure may be different from it in your state. If you have a reliable statistics, let all of us know about it.
By strut you mean this?
[QUOTE=dip097;1058763] I deserve Rs. 450 if you consider the petrol charges for getting there. [QUOTE]
I need not be bothered about it but just pointed out that they levied too much which led to the refund of at least 350/- rupees.
[QUOTE=dip097;1058763] They changed the gasket in front of me. [QUOTE]
Good. But the leaking is still there. Well experienced mechanics and more well experienced service manager. They are national assets wasting their expertise in a small Suzuki workshop.

Don’t know why, editing and replying multiple posts becomes more and more difficult.

Re: Suzuki GS150R : Adjusting Rear Suspension

Done. I think you format text, size & colour and those codes take space. Go with default text, size & colour; speed should be better.

Re: Suzuki GS150R : Adjusting Rear Suspension

We, dip097 and I, are still good friends or we were so at least up to a few weeks ago. Yet, let there be peace everywhere and let it begin with you.
Thanks for the tip. The problem is that, due to my ‘rich vocabulary and perfect grammar’, I need more editing and hence more time.
If quoting the full post, it is OK but when trying to edit it, it is difficult to select and delete a part.
