By "stuck" i meant that when the engine gets hot, engine sounds increases and then if you try to rev, the bike shows a "to and fro motion" as engine is trying to move but its not able to. It was more prominent in first 1000 kms, now its better than before.One can feel it in foot pegs and handle. I think everyone is experiencing a roughness at around 3.5K rpm at all gears, this is one is similar to that.
@ Augustine
The to and fro motion is similar to choking when there the engine is not getting adequate fuel, when it occured engine was hot and fuel was well above reserve level.

At present I'm using stock engine oil, when can i change to semi-synthetic or synthetic oil? And also i think the chain is making some noise as well. Do anyone lubricate chain by themselves. Then please give some advice. My friend having FZ said since chain is exposed, he cleans and lubricates chain once in 2 weeks. Within two months I have already tightened the chain twice, is it normal?

Ha, engine gets hot pretty soon during running in period. For the entire 2000 km i haven't rev it more than 4.5 K mark. The top speed to which i have driven is 87 and that too not more than a few seconds. Soon reduced the speed to 60 and then engine was a little more noisy. I think this will go away after third service. But even after these noises the mileage is above 50 with a pillion.

Sorry for the "no-paragraph" post. It did't look that bad when I was writing it.

About the engine roughness, come on guys, any engine will get rough once it exceeds a particular temperature. That is because the engine oil viscocity is reduced at higher temperatures. That is why high revving engines prone to more heat use liquid cooling. In the break-in period the heat produced is more because the internal parts are not seated well with eachother. The more you ride, the better it will get. And moreover if the mileage figure is good, it is an indicaton of good engine health.

Anupdas, as a kid have you not had a new bicycle. Havent you noticed that when the cycle is brand new the chain keeps getting loose for the first few months. It is the same with bikes and quiet normal. After the chain is subject to enough load it will be good. Usually bikes need to get their chains tightned every 2000 kms or so depending on the riding.

I've never crossed 93km/h in my bike so cant say much about sound after 100..
But the scenario is pretty much the same..
When engine gets hotter, the sound starts to change..
Even vibrations increase a bit at foot pegs (if u observe keenly you can feel it, its still very less but)


I think after 5k you can use semi synthetic and after its life comes to an end, put full synthetic oil..

For me the bike revs freely even when engine is hot, and that choking thing happened only once.. I'm just worried about the sound..


@ Augustine:
Even i'm considering changing to a w50 oil. the roughness will most likely be due to oil not withstanding the high temp of engine.

But i heard w50 will make the bike sluggish(especially in the mornings) as its thicker.

I havent noticed that while riding bicycle, but with motorcycle it becomes very evident as you find it difficult to ride at low speeds. I'm a little worried since my friends( well they don't like GS) is trying to find each and every defect of GS. They were complaining that the bike is very noisy even noisy than pulsars. Last day in an article i read that loosening of chain is also indication of wearing.

Thanks for reply bro, so far I have been riding in between 4K-5K. Last day i read some posts in Apache thread, those guys were discussing about 10K rpm, i was totally shocked . Ideally a gear is shifted up when a gear fails to accelerate, but i have felt that in initial gears after crossing some 5K there isnt much acceleration, shifting is very jolty and very uncomfortable.

Hmmm, my bike has pretty good acceleration beyond 5k dude.. i've revved upto 6-7 in 2,3,4 gears.. it was pretty awesome.. especially for overtaking other vehicles.

May be ur bike isnt used to revving as u ride at 4.5k most of the time..

10k and all i wont try in my bike for a long time to come

The GS can rev upto 9.5K RPM in the 4th and 5th gear with very powerful acceleration. The red line starts at 10K RPM. So the GS is not made to rev that high. Its made for a smoother ride. The Apache vibrates like a vibrator... because of its capability to rev hard. But it is this ability that gives it the power punch feeling.


Which part of Trissur are you from buddy?

Thanks

I have revved in 5th and 6th gear to 6.5 K once to a speed of 87 only for a moment. The noise of engine made me to reduce the speed to comfortable 60's and there was also cross winds. Earlier i complained about poor front end traction at high speeds, now i feel like the front is glued to road. Have to put some effort to sway side to side. To make engine free revving, you need to rev to 6-7K mark rite. Or will it happen naturally if i ride in usual 5 K range. So far i have clocked 2300 km on ODO, so its safe to go for semi-synthetic after second service rite.

Rust

When I got delivery in the evening of Feb 18th, I had filled petrol that night.
After that I went to fill in petrol today morning, and filled 200 Rs worth of Petrol, while I was about to close the lid, I saw that dreaded sight everyone was talking about.....Rust.

I was speechless for a moment, took the bike to a shade opened the tank and stared at it for a good 2 minutes, about 60 % of the fuel lid (mouth tunnel) was rusted and this is a 2 weeks old baby.

I thought and believed Suzuki have fixed this issue for 2010 bikes. But why Suzuki Why....

And moreover the squeaking sound came back again. I was nothing short of being furious. Started the bike headed straight to Jains Suzuki.

I showed the rust to Mr.Pandian, he didn't seem too surprised (but was pretty apologetic), and called to one Mr.Mohan (I think the service head), he was a good and polite gentleman. He inspected it and told, we will replace it sir don't worry.

I heaved a sigh of relief and complained about the squeaking sound from suspension, he sat in the bike and jumped up and down, the sound was clearly audible, he told it is coming from the Swing arm bolt, and it will be fixed. He seemed to have good knowledge about the bike and was talking with me regarding other aspects of it.

Then he asked how much fuel is there in tank, I told about 7 litres, he then asked them to get a can and remove the fuel from the tank. Then asked me to wait for sometime in the waiting room, their service and care was very good.

They first fixed the squeaking sound issue.
Then after sometime Mr.Mohan came back and told that the available tanks has the same issue , and he will let me know when newer tanks, without this issue, arrives.

He told not to worry about it and they will surely replace the tank once the replacement comes. He also told, not every bike has this issue, but few still have it, but they will surely replace it.

The service guys were really good, and I almost forgot the anger against Suzuki because of them.

I thanked them and left. But I really hope Suzuki to recall their bikes and replace the tanks, as this will put an end to this issue once and for all.

It very sad to know that rusting problem has not been fully resolved by Suzuki. Does this rusting has to do something with the petrol using. I just inspected tank, no issues so far. I had that squeaking sound before and they lubricated the bolt and its gone. Don't worry brother all your problems will be fixed.

Mate, I think you are getting too worried about your bike. Each and every bike has its issues, its just that since GS is a new machine its been talked about a lot.

Just enjoy your ride, if not, we can always have a whole list of issues to worry about in every bike.

Thanks buddy. No I don't think its an issue with the Petrol, cos only the mouth tunnel (not on the rim) has rusting and the inside of the tank doesn't have any.

Yes the squeaking sound is gone now.

The manual says rev freely upto 5000 RPM within 800Kms, upto 7500 RPM within 1600Kms and upto 10000RPM after that. Since you have already completed 2300Kms, dont shy away from letting the bike feel its own power at leat once in a while. The manual also says, constant low speeds will lead to glazing. So once in a while do a drag. See what the GS is capable of. Which part of Thrissur are you from? Watch out for safety though.
About oil I think you should stick to mineral oil atleast till you clock 10,000 kms. They say, "80% of the breakin happens in the 20% of kms covered and the rest 20% takes the 80% of kms." (Dont ask me who are they ) What I mean is though the initial breakin complets in 1600 kms, it will take some more kms for the breakin to complete fully. So its good to wait before changing to synthetic or semi.
