Re: Suzuki GS150R

Hello guys,

I have noticed some kind of feeling developing on forums concerning Gixxer and related lightweight motorcycles offered by Suzuki (Gixxer SF, V-Strom 250, etc.), now that both GS150r and Inazuma are gone (I believe globally). It seems like a void is being created for a new motorcycle that could be a true replacement for GS. Call me nuts, but IMO, a touring Gixxer (with raised handlebars, more comfortable single seat, decent brakes and tyres, good lighting AND lower weight compared to GS) could be coming from Suzuki. Of course this may never happen, but it would be nice, don't you think? BTW, I am not sure if a 6-speed, 150cc bike like GS is ever coming out of Suzuki's stable again, but that would be absolutely welcome. I mean, there are people complaining about how uncomfortable Gixxer is, and many have deplored the lack of 6th gear on the bike. Just my thoughts.

Anyway, regarding GS these days..! I have found a difference between mineral and semisynthetic oil; after 2,500 Kms, level is exactly the same with semi (Repsol 10w40 Sport) AND power is still great; I am thinking I could push the oil to about 3,000 Kms, as planned, without any noticeable loss in performance. I do not think I am going back to fully synth for some time, as I don't think GS needs more expensive oil. My CR9EHIX spark plug is running great as well. Also, I have washed the modified air filter a 3rd. time with good results, one more time. I don't believe I should buy a new air filter, as the mod on my filter took me about 2 hours to finish, and it is a bit expensive here! I thought I should mention tappet noise is kept at minimum levels and valves seem to be in top shape, considering performance alone. My next project is removing the carburettor to copy the settings that have worked so well on my bike, just in case I switch to a Special Edition one.

Talking about mods, upjetting the bike some months ago was probably the best investment on the bike, as even the exhaust sound is that of a bigger cc bike and the engine cooled down even though I rutinely hit 8500 rpms on the open road. This could actually increase engine life, and at 23K kms, the engine on my GS is still young. My advice is guys, before considering getting a bigger motorcycle, go for refinement and a trusty engine and just keep your GS! In other words is, keep your bike in top shape --modify it if you want-- and trust Suzuki India will continue to provide parts for a few more years. Dealers in Mexico are handling demand quite decently. The parts I am not getting as a direct fit for GS I get from Gixxer or they order them for me.

I am still deciding which tyres to fit on GS. Has anyone switched to 110/120 mm lately, how about other improvements?

Cheers,

Gil

Re: Suzuki GS150R

Hello xbhpians,

I have Recently bought used Suzuki gs150r.

I am new to biking and I have no idea about the service centers here in bangalore for this bike. I stay near ramamurthy nagar.

Need your help on finding the best service center here.

Thanks

Re: Suzuki GS150R

This issue with choke cable occured again and this time rather than replacing the cable, I just cut it near carburetor leaving a little length looped which I can pull to choke the fuel circuit. Would be a good fix for people having similar issues frequently with their choke cables. FYI.


I recently moved to Bangalore and found Value, and Meghavath Suzuki closest in this area, though haven't been to one yet.

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 !

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.

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: 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


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

hi

its time for tyre change.

how about michelin sirac street TT.

any other suggestions are welcomed.

thanks

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

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

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

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

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

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.
