Re: Suzuki GS150R




Oil Leaking issue in my bike.

I could see wet patches near gearbox [photos attached], it leaks 3-4 drops a week while parking.

Is this a serious issue??.

Re: Suzuki GS150R

Welcome to the thread ! I too have idle-d my GS for long. What cables did you change? How many kilometers has your GS done?

Re: Suzuki GS150R

Good to see activity on the GS 150 ownership thread. Its time the rest of us pitched in as well.

In between my travels I haven't had much time to use the bike and took it out for servicing today after a long time.
And boy, after the regular service and a couple of cable changes, it feels like new again.

I was looking for an option to change the tyres as well since I was still running on the stock ones and needed a new pair of shoes for any long rides that I may take.
Decided to switch over to tubeless as that would be more useful when on a drive.
Was looking for options and could not find much.

The websites for Michelin and MRF do not offer much options for 18 inchers.

MRF has the stock Zappers, front FS and rear Y in tubeless.
Michelin had the City Pro available in tubeless but not the Sirac as per their website.

Was also wondering if I should upgrade the size to a little fatter one than stock and try if that makes any difference.
I know it is recommended to stick to the stock size, but what the heck, you can always change.

Was trying the forums but did not have much help on for choosing the right tyres.

Finally decided to go out and explore in the shop directly and find out what options I have.
After some window shopping and asking around , finally found and concluded on the following set.

Front : Michelin City Pro 80/100 47 P Tubeless
Rear : Michelin Sirac Street 110/90 61 P Tubeless

Its still the first day and I will wait before I pass the verdict, but they do feel good on the first ride.

My choice for 80/100 was only that I wanted to move away from the stock size, and theoretically the 80/100 should be bigger than the 2.75
But side by side, there isnt much difference between the both, and if any, I felt the 80/100 was marginally bigger than the 2.75 by an mm or two.

And the 110/90 obviously since I wanted a bigger tyre, and also since it was a Sirac and it was Tubeless. (though Michelin's website does not tell you so)
BTW 110/90 does fit comfortably.

So all in all, I got the tyres what I was looking for, and hope it helps others who are trying to find a fit for the GS.

Got the tyres done at MV Tyre Plaza near Satyam Theatre , Ameerpet , Hyderabad.

Cost - 1800 for the front, 2800 for the rear. 200 for the steel valves for tubeless and 60 for fitting. discount -100. Total - 4760.

Re: Suzuki GS150R

Reporting back on the thread after a very long time (more than a year to be exact).

Did a few things with the GS (lights, seats, new rear tire, changed spark plug and air filter) but other than that it has been a year of quiet ownership. Good to see people here doing their best to keep the thread alive.

This post is because I read a couple of pages back about the Service Manual. I too had downloaded the Spanish one years back and sometime back, had it translated to English using an online tool. It worked well I must say. Only the images rendered in the translated copy might seem a bit fuzzy at the edges. But then again, that could just be me. You could always look up the original Spanish version for original HQ images.

Here's the link btw. Hope it's helpful.

EDIT: So I scrolled through some more sections of the translated stuff and it seems formatting is a bit off, especially when it comes to tables and items within them. Sorry if anybody got their hopes too high and was disappointed subsequently.

Re: Suzuki GS150R

Changed the stock tyres after 51k to Michelin sirac street .
Grip is good..but front side of the bike is swaying to the right side while turning and also feels heavy while turning the handle bar..
What could be the reason?

Re: Suzuki GS150R

Sad looking shocks there..my front shocks do have traces of rust already..spots here and there,. I dunno if it is psychological but I'm seeing differences in the suspension while riding..like it is softer and wobbles a bit more than usual, but I'm not sure if that is due to the newly laid Chennai bypass. I was thinking of getting the shocks rectified from a local mechanic..but if replacing them would be better so be it.

Atleast out of the known problems, I seem to have addressed the poor headlight problem of my GS.

Re: Suzuki GS150R

Better to replace it as a pair.

Early leaking of shock absorbers at rear is a known problem in GS. I have not used my GS for the past 7-8 months and this is how the inner tube of the shock looks. At my best, I can remove the rust with WD-40 before moving the vehicle but any rust not removed would definitely puncture the seals, even if I remove the rust, the "pit/hole" created would lead to a leak. Similar rust on front shock inner tubes - my guess is that Suzuki wanted more strength for these (rear shocks and front forks) and Gabriel added more iron/steel and overall they didn't do extensive/longer field testing.



But I wonder why no GS'pian changed the shocks to CBZ/Hunk/ZMA/RTR - such a swap is not possible?

A Honda Shine parked a few meters away from my lot and not used/moved an inch for last 2 years doesn't have rust at those places.

P.S. Am not regular with the maintenance but manual doesn't mention any long-term precautions for rear shocks. Front wheel bearings, cylinder head gasket and rear shocks leaking early are known GS flaws (According to owners reports here) along with poor headlamp and bad rear brake. My area is less than 2 kms away from coast - salty air adds to the damage as well.

Re: Suzuki GS150R

Michelin sirac street is absolutely fine and i use it in rear wheel, will provide you nice grip.

Re: Suzuki GS150R

Hey guys.. Is 41K kms okay to get the rear shocks replaced?.. My GS seemed to leak oil after a service at 41k..I thought it was probably lubrication from the newly replaced chain sprocket..serviced at 49K at SMK, nothing rectified and now service at 52K, another service center says it is the rear shock leaking and it needs to be replaced...cannot be rectified.
My qn: Is this the life of the shock absorbers?
Should both of the rear shocks be replaced at the same time?..won't replacing just one interfere with suspension quality?

Re: Suzuki GS150R

hi

its time for tyre change.

how about michelin sirac street TT.

any other suggestions are welcomed.

thanks

Re: Suzuki GS150R


True that. ~83@6000 RPM is the sweet spot indeed though it is sure capable of cruising at 105-110 for hours which I did on Pune-Belgaum route. (320km in 4 hrs, Only slowed down at diversions, speed breakers, traffic & a 10 min break)







Have topped mine to 131, with stock parts no performance mods, with some wind assistance and road decline. P.S. not in the above ride.

Re: Suzuki GS150R

If one is after performance/speed with GS150R there are several things at fault here : GS is jack of all, master of none.
Weight of the bike & the rider; GS's power-band is of a road commuter. If you ask me, Ninja 300 should be affordable for those guys who constantly fit in after markets on stock motorcycles.
As for GS, even cruising beyond 6000 RPM on an empty highway is pointless. ;-)

Re: Suzuki GS150R

I have a Brand new engine done 4 months back and the bike has good power in all gears, I have pushed it to 100 but did not push it above am not sure it can go over 110 unless I try sproketing that too might make some diff, the only option is NOS kit, (single dry fogger), few guy in North india have installed a nos kit in a pulsar 150 and results are great, i.like gs for the smooth engine and 6th gear, try nos but be very careful,

Re: The 150cc beast with 148kmph 🔥

I'm sure folks here would be glad to help. But the speeds you have posted must be with the bike on stand i bet! It'll take ~11k rpm to reach 148-156 kmph unless you've changed sprockets. Don't mean any offence but I would laugh off such claims anyday.

The 150cc beast with 148kmph 🔥

Hello guys , this is my first post and I already apologize for any mistakes made in the following.
So I own a GS150r , near bike which was my brother's choice as he is an automobile engineer .
It is now 9 years old and still goes around 130 on 'economy'.
The most I took out from this bike is 148kmph and my brother took it to 156kmph !
Yes , this beast is overly powered and heavy.
It's really well maintained since 9 years only had one tyre change and has minor scratches .
I need to modify this beast now and I am really confused as I don't know anything about the technical aspects.
Please help !
-I need to thicken the tyre in the back .
-Need a little more fuel efficiency because tyre would effect so I guess I'll need balancing , it currently gives 42kmpl easily , thou I ride rough.
- need to change mudguards as I am basically changing it for looks
Please help !
