Re: Suzuki GS150R

Is the RPM increasing when turning the bike to extreme left/right ?

Could you check your carb cleaned out/tuned along with checking Throttle cable and choke cable.

Re: Suzuki GS150R

@anonyblr,

After going through your initial post #19998 and the recent pictures, this is what I felt:

1. It was unlikely the clutch plates got ruined after the accident. For something to hit the clutch cover and that in turn bending and damaging the clutch plates is rare. The clutch cover (or called the RHS crankcase cover) is so thick that it will simply break in a major accident. I think you presented with a complaint of "lack of power" and SVC connected that and the accident and replaced the clutch plates and cable.

2. In the "while studying" phase, did you lend your GS to your friends? If yes, we are looking at possible abuse and that might be the cause for premature clutch/piston rings/valves failure. There is no other way a 2008 batch GS will fail this way. Am assuming you serviced the bike regularly (which means regular replacement of engine oil and filter which also greatly affects piston ring/cylinder life).

3. Poor mileage might be the side-effect of a "worn out top end". But, was it only giving 35 kmpl before all these problems started? That itself is a bit low for GS unless driven very aggressively. There should be something as simple as a compression test at SVC for detecting problems with the head.

4. For idling issue: A. drive for 5-6 kms to warm up the engine and you yourself set the idle screw to tacho indicated 1500 rpm. B. While braking, don't keep the clutch lever pulled in - that will bring the engine to idle and if it isn't warm enough, will shut down. Just downshift and leave the clutch lever out. For 1st gear with engine running (not warm) - you can very very slightly increase the throttle to maintain idling rpm. If this cannot be solved this way, have the carb checked, cleaned and tuned at SVC. (C) Also check what [MENTION=40024]BlackPanther[/MENTION] said.

5. Pull out the spark plug - if it is oil fouled, your engine is drinking oil.

@BlackPanther

Thank you for replying.

And no, it is not increasing when turning the bike to extreme left/right.

To give you a clear picture, consider i'm riding at 55-60 km/h in 6th gear (RPM is at 4000-4500) and i need to brake. I slow down to lets say 25 km/h (the RPM stays at 4000-4500) and apply clutch to shift down (RPM stays at 4000-4500). And all this happens only when fuel levels are down. When I get it filled, there is no such problem.

I will get the carburetor cleaned up, and get those cables checked and let you know how it responds.

Thanks.

@ashwanth.r

I think that post answers many of my questions.

(1 & 2) I do admit to some poor maintenance in the past, which probably caused damage to the clutch plates.

(3) Also I have to mention my current usage pattern, I use my GS for an average of 2-3 km per day, a 1-1.5 km commute. So effectively, i turn off and start my engine every 1-1.5 km. Hence the low mileage of 35 km/l. (It has always been that much, max. of 43-45 km/l on highways)

(4) i have already been doing all the things you mentioned in the 4th point.
(5) no oil in the spark plug.

But the sudden dip to around 25 km/l after my last oil change (around a month back) is what i'm worried about (even on riding within 4000 RPM, no sudden acceleration). So, that made me think of it as something related to the engine oil. But having said that, the performance in AX7 has been better than the previous 20w40.

I will get the carburetor checked and let you know how it responds.

And if any thoughts on the engine oil, please do let me know.

Thanks a lot

Re: Suzuki GS150R

I urge you to take up riding a bicycle or even walking for that distance(1.5 km).

Re: Suzuki GS150R

Any idea why the gas stove-type fuel knob is too tight to turn? Mines that way now - I could literally hear sand particles getting crushed inside. Can it be removed and cleaned or is it a sealed unit? I know the fuel filter sticks can be cleaned.

Re: Suzuki GS150R

Exactly what you heard. Stuck dirt. I think it can be removed, or maybe spray some water there.

Re: Suzuki GS150R

What a co-incidence. !

It will be very difficult when fuel knob needs to be changed from ON to Reserve that too when riding.

It felt hard for more than a year now. I removed the tank last weekend to check the tappet adjustment. While fitting everything back, i tried to check why is it very hard to change the knob.

Remove the side cover (for ease of work). Remove the fuel knob (Single screw in the middle). You will notice 2 small screws again which needs to be unscrewed to remove a washer. After removing the washer, use some kerosene and a toothbrush for cleaning the area.
Spray some kerosene or some cleaner as there are tiny areas which cannot be reached by any tool for cleaning.

The washer actually is to prevent the knob being rotated in the clockwise direction from ON position and anti-clockwise direction from Reserve position.

Re: Suzuki GS150R

Replies inline.

Re: Suzuki GS150R

I don't find any rubber parts or O rings in the area. But after the clean, it is easier to operate.

Yes, the washer to stop the knob from turning the other way around.

And I did the tappet adjustment as i posted earlier that I received noise after initial tappet adjustment.

Re: Suzuki GS150R

For people who want to clean the oil strainer but can't get a SGP o-ring for the cover (in case the o-ring is chutney and damaged), TVS Apache oil strainer cover o-ring is a direct fit. But it is priced a bit high (INR 55). I think Suzuki's might be cheaper.

Ramkay (Adyar) didn't have the oil filter small and big o-rings. Next have to try whether they match.

Fails: Apache's oil drain bolt with magnet or the sealing washers won't fit our GS. Bolt is 17 mm but the thread is smaller :-(.

Re: Suzuki GS150R

Coming to this thread after along time, I and my bike spent 5th anniversary last month, traveled together just for 29K Kms but still a strong bond. She protected me from a big accident an year back taking much of an impact with a broken mudguard, bend handle, crash guard, clutch lever. She was treated well and back to her best.

Due to frequent travel I have not been able to use her much. But change oil every 6 months or 2000 KMs(Shell AX7) but I have been dogged by an issue recently where the gear indicator display doesnot show 5th gear, I also feel something wrong when I shift to 5th gear(basically the ply to move from 4th to 5th). Just curious to know if anyone faced this issue before.

Re: Suzuki GS150R

Welcome back. I keep facing this issue but very very rare - happens when I shift too lazily and the gear didn't actually engage (false neutral). Another gentle shove of the gear lever will engage the gear - for me, it happens only for 2 to 3 and 4 to 5. For you, goes the gear actually engage when there's a blank?

Re: Suzuki GS150R


Thanks Ashwanth !
I too face the false neutral issue very rarely but mostly when I shift lazily between 1 to 2. But for me the 5th gear is permanently off the electronic display.
I wonder if it could be any of the below reasons:

1) Gear Sensor (I dont know how the gear indicator works, probably someone can chime in)

2) issue with Gear teeth (probably rare as I dont loose drive in 5th gear)

3) Clutch lever

Please let me know your thoughts

Re: Suzuki GS150R

Sold my beloved GS150r today. A sad day 😔

Re: Suzuki GS150R

I don't know the intricacies of that mechanism but its definitely nothing with the clutch lever as that would mean a blank for all the other gears. Probably the sensor isn't activated for 5th but what is confusing is 6th is again properly displayed for you.
