Re: Suzuki GS150R

Hi Everyone!


Yet again, I need some information and since I am out of town, I don't have my bike with me...please, it will be great help if anyone can find time to reply.


Attaching an image, drawn by hand so, it's very rough/approx. Maybe the terms I have used are incorrect, so I would like to explain - when I say "Throttle", I mean the extreme right end of the steering handle bar which we twist to increase/decrease fuel supply (and hence, the bike speed)


I would like to know what is the value/measurement of 'X'(the diameter of the actual part of the throttle which we twist/throttle) and 'Y' (the diameter of the edge of the throttle...this part is fixed and cannot be twisted).


Thanks..happy riding!

Re: Suzuki GS150R

Hi Everyone!

My bike is just a few months old and the engine oil is still mineral oil (the same which is supplied/changed at suzuki center during servicing), running smooth without any problems. I have read here in comments that some people have done a tour of several KMS (300...upto 600 Kms..maybe more) in a single day. Some have even done more than 1000 kms in a single day. Well, I have few questions:

1) I want to ask if while doing these long trips on bike (with or without pillion + luggage) should there be a need to stop the bike and give it a break to cool down? I mean, o fcouse, the rider will also need a break every once in a while, but I'm just talking about the machine which has mineral engine oil which is in good condition (ie the oil has not clocked and will not clock 4000 kms of it's life during the present bike trip/tour) - should there be a need to stop the bike to let the engine cool down during long rides?

2) Also, just wondering, if mineral oil can handle long hours (8-10 hrs in a day) at mildly higher cruising speeds (60-70-80 Km/hr) or should one change the engine oil to semi synth or total synth for these long distance tours?

Thanks..happy riding!

Re: Suzuki GS150R

Hey Guys,

I am just about to complete 28,000km on my 19 months old GS. Got done 14th paid servicing this saturday and haven't missed a single service as yet. Overall the bike has served its purpose to the fullest and is continuing to give the same smoothness, comfort and ride quality even today.
My recent problem with this bike started with 13th servicing when I instructed the service guy to adjust the valve clearance as I could hear some cluttering noise from engine head. After this adjustment the cluttering noise was gone, but I could hear very small but irritating throaty grunt at ~4500rpm. It was also accompanied by very small but noticeable vibrations. So I thought the valve clearances were not set right. During 14th service I told the service person to kindly re-adjust the valve clearance but he said the noise and vibes are normal since bike has clocked 28k km and there will be some vibrations now on. I wasn't really convinced but I didn't argue coz I didn't want to lose my temper at them.

After coming back from 14th service, I bought a Taparia tool set (pack of 23), 5,6 & 10 mm allen keys, and a feeler gauge in a local shop. Thanks to the service manual shared by some awesome guys here on the forum, I adjusted the valve clearances to 0.04mm (intake) and 0.1mm(exhaust). After this adjustment the bike seems to be even smoother and no vibes at all. Also the throaty grunt is gone. I would like to redirect you all to this awesome post by @Drifty which inspired some confidence in me to do this by myself.

Sorry I couldn't get any photos or videos to share as my hands were all greasy and I didn't have anyone to help me along. Thanks to all the members for keeping this forum alive and sharing awesome information.

TIP: Keep your bike OFF vernight before adjusting valve clearance. I think the service guy did adjust the clearance well in the 13th service but the engine was hot then as he just test rode the bike before service.

This was my first major DIY activity on this bike. I had only done some minor DIYs before like tightening the chain and changing engine oil. I am going to take up full DC conversion when I change the engine oil.

Re: Suzuki GS150R

I think you mean, keeping the motorcycle off overnight, cold engine is a requirement.

Re: Suzuki GS150R

Yeah sorry about that. Edited the post

Re: Suzuki GS150R

reply awaited..

Re: Suzuki GS150R

Try both of them back to back(3,000 kms apart) and decide for yourself.

Re: Suzuki GS150R

Bro if he wanted to try both, he would not be asking the question here. BTW motul seems good no idea about the other.Also pls change your oil filter when changing to a oil of diff grade.

Re: Suzuki GS150R

Well just last week I did a non stop ride of 300kms on my 2009 model gs150r which has run for 27000kms. I started my journey at 4:15 am ane finished my ride at 8:35 am, precisely 4:20 min. Maintained constant speed of 80 kmph at 6000rpm. There was no sign of overheating of the engine. Even after completion of my ride the rpm was stable under 1500 rpm. Just changed the oil before ride to shell ax5 20w40 mineral oil and shell V power fuel. I didn't switch off ignition even for a minute through out the ride. Just felt bit tired in last 30kms but decided not to stop and continue until I reach my destination. Truly a proud owner of gs150r. Indeed a very capable bike for tourers.

Re: Suzuki GS150R

Hi everyone

I would like to confirm few points regarding my GS150r's recent problem. First off bike has done ~35K on ODO now. I changed to shell synthetic oil (10W40 which is okay as per manual) when ODO was 32K since the oil level was at L level. When the ODO was 34K, I noticed that engine oil level was dropping to level L in the engine oil window again which is not expected. Worried I took it to service centre to check it. They noticed that
1. Dark powder like deposits on the silencer interior walls
2. Oil level drained down was less than 100mL.

They said the bore of the engine might be damaged and reboring may be required. Service manager (saptagiri suzuki) blames the petrol (adulterated ones can damage engine and he suspect this is the case.. I always fill petrol at shell.. Where else can I fill petrol now? ).. the mechanic blames me that I haven't regularly checked the engine oil - come on dude, i service the bike atleast once in 3K kms at your showroom.. never got it serviced from a outside guy. I have been taking good care of my bike and check engine oil levels every 500kms. We buy 150cc desi bikes just to have least worry about the maintenance part but I am expected to take care of it like its a 1000cc GSxr...

They filled another 1000mL oil at 34K filled to F level..


its 800kms now and oil level is back to level L...


I just CANT IMAGINE a 150cc motorcycle from suzuki can have CRITICAL issues such as this at just 34K kms?!! May be my bike is the unlucky 1-in-100 but still this is not the quality that I expected from SUZUKI. If there is a real issue with the engine now (which I am sure is the case), I am just deciding never to buy another suzuki or any locally manufactured motorcycle just because of the kind of quality they provide us and kind of SERVICE the showrooms offer, the skill set they have .. I am just afraid to upgrade to a new motocycle now.... Better I switch to my cycle .. And yes speaking of pollution when cycling.. I am just fed up!

Re: Suzuki GS150R

1. Dark carbon powder deposits at the exhaust exit => rich AFR. Check choke, idle and air-filter...
2. Synthetic engine oils may get burnt, 100ml is not a big issue.
3. I'm not sure if it's ideal to have engine-oil level at maximum.

Good luck with cycling and CKD/CBU motorcycles.
