Brat,
I dont know if that guy is right or wrong but these days most of these high end products come with full synthetic oil from factory itself. Even cars with the 15000kms/year service interval come with fully synth oil.
I asked the serv centre to change oil at 1000 kms for my car but he said its not wanted and the company doesnt require change before 15000 kms.

Even bikes like R1, Busa etc must be coming with fully synth oils from factory itself, they wont survive on mineral oil
There is a very high chance that GT came with fully synthetic oil from the very first km as many companies do it now - i read on Motoroids or somewhere that Garware and Hyosung only recommend fully synthetic oil for this motor.

In short - am switching to Motul 300V around the 900-950 kms at first service, most of the running is done by now and what i feel is that this mineral oil and very easy on the engine for 1000 kms was for old engines, just dont rip the bike and put in the fully synth oil is what i do.

Did you check for any metal filings or anything of that sort in the drained oil or filter - you would hardly find anything

Hi all there, i got some problems in my bike and i would like all people here to suggest me best for that:

My hyosung GT 650R's rear tyre was punctured some days back. I got that corrected and just after that gave bike a run of 90 kms almost. When i parked bike at home after that the same puncture was leaking. Now when i asked hyosung people about this, they told me to change the tyre and also i will not get any claim for this. So please advice,

> Should i get the tyre change or look out for puncture correction?
> If i get the puncture done, will it effect the running of bike as i experienced some wobbling before too in rear?
> If i get the tyre changed please suggest which tyre will be best for me. Presently i think it is bridgestone.

First you wont get any claim for it as its neither covered under Hyosung warranty and nor under Insurance so you will have to foot a big bill for it.

Second,if they are asking you to replace it without any reason just like that then its ridiculous. Just use your muscles man and get a under warranty replacement... hehe

A punctured tyre which has been repaired doesnt affect the handling in any way, its only if you get 10-12 punctures which is not the case with you. Regarding wobbling, try getting your wheel balanced/aligned.

A sole puncture in a tyre doesnt demand a replacement, if your tyre's sidewall is intact then take your bike to a good tubeless puncture repair shop and get it done again.

Am sure this replacement idea was given to you by the Gurgaon svc guys, they are so damn foolish, lets go together and give them a peace of mind. They cant get my bike registered in 15 days - have to call them every alternate day.

There is an alternate to leaking puncture in tubeless tires, if it is not on the side wall.Go to any reputed company tire dealer and he will be able to put a PATCH inside which will cure this..I learnt about this when i had taken a Toyota Camry for a puncture repair.

You are right, Gurgaon SVC guys told me this. I am in jaipur and my bike is there in workshop, its having other issues too. So can't go there and talk to them on this. They told me the puncture is near to sidewall so it can't be corrected.

Bro. Its not on sidewall actually but quite near to it.

In that case the puncture can not be corrected...you can try putting a tube inside and get over the problem , if you prefer ...

Putting tube inside would not create any problems further in performance of bike? I think its not possible to get a tube of that size here. I am unable to waste a lot time behind the tyre work and all, as everything is in gurgaon and i am in jaipur. I have to go there first which takes 6 hours one side journey and have to search such a lot things in that place where i really don't know exact locations for right kind of thing. This is damn time wasting including money too, in traveling and all.

Also i am still not sure that the puncture is so close to sidewall. I checked it only once when it was punctured and after that i never checked it. Probably hyosung people are trying to sell me another tyre without any reason, just to earn some more money and saving themselves from the making the efforts to get the puncture done.

BDW any idea, which new rear tyre will be best for GT 650R which can have more grip on road? Please let me know about prices too as i am afraid that SVC going to charge me more for it.

Bikes like R1's and Gixxers are I4's and they have high revving engine's. They heat up relatively quicker compared to vtwins and most of their punchy torque is accessible at relatively higher RPM's and therefore those machines love to redline rather frequently than vtwins.

in our case - the happy place starts beyond 6k and ends short of 9k rpm,
it is quite true that the bigger I4's run on FS oil on a bone stock SBK.

I was enlightened recently that, the fully synthetic oil particle size is only a fraction of what a Mineral oil particle or semi synth oil particle would be, chances are likely that the piston rings would scrape against the wall to smooth itself out over a period while the engine is running in. FS oil has more tendency to leak into the chamber than mineral or semi synth oil.

It might be true that dinosaur oil (mineral) is ineffective in performing on par with higher engine capabilities but semi-synth oil offers the best of both worlds. Average particle size with the additives and technology available in fully synthetic oils.

So, i opt'ed for semi-synth oil for the 1st service to allow the engine components to become sealed properly and then switch to Motul 300v from second service onwards.

I had indeed checked the drained oil, i was expecting to see some metal filings in it and found nothing. The mechanic gave me a confused look though.

The Bridgestone battlax which come as standard is quite reputed and is reknown for both wet as well as dry weather riding. The only downside of this tyre is that it lacks in technology, uses single compound for the entire tyre and compound is relatively harder to give it longer street life but takes forever to heat up.

Look into Michelin Pilot Power 160/60ZR17, It is dual compound based - meaning, hard rubber on the straight contact patch and progressively softer compound towards the walls for excellent cornering grip. This gives it good life as well and the synthetic materials used allows it to heat up faster than the stock battlax. I met a Michelin dealer yesterday to have a rear tyre swapped for one of my other bikes, i can get in touch with him today to see if he can make one available.

Good decision bro

Melroyal:
Best of luck for your Ironbutt outing!

For all of you who had questions about the Oil being used by Hyosung/Garware, they use Castrol Fully Synthetic 10W40 oil in their bikes. They recommend using the same even after the first and second service. I would recommend using that for the first 1600 KMs and then switching to any compatible oil you want to try.

Vikyk:
Bro, good job on scaring away the monkeys with the chics and their stupid two wheelers. They deserve that treatment.
About your puncture issue, please upload the pictures, its very difficult to treat severe punctures on these kinds of tyres. Check with a good superbike mechanic or a tyre dealer or with high end car service people. Get an inside patch as suggested and get a Nitrogen filling in both your tyres. I would recommend that to all the Hyosingers.

To all:
Bridgestone Battlax tyres are pretty good but need to heat up for providing good grip. They tend to skid a little on muddy and slushy roads due to the way these tyres are built, most part is flat and soft and these parts are the problem areas. For city riding, a bigger tyre with some muscles would definitely be better than the stock flat profile tyres. This is an issue with all superbikes. These tyres are meant for Tarmac and not for city roads.

Thanks bro

Hey brom, thanks for the advice. Any idea from where i can get Michelin Pilot Power 160/60ZR17 tyre in gurgaon or delhi. The only issue with me is that i am in jaipur and i can't stay in delhi/ gurgaon for more than a day for this. So some direct known shop would be great help.

Thanks for that appreciation, i wish i could be able to break their noses for once atleast.

Well, i don't have any pictures of the puncture. And i explained above, i have no direct contacts or time to search such places/people over there so any links of such tyre dealers, from any one would be great help.

I felt same thing that tyres skid a lot in starting and definitely a bigger and tyre with more grip will be best. Is is possible to put a heavier tyre in bike like 180 or 190 rather than 160 ? And also please suggest company name for such tyres?

HELP NEEDED EARLIEST in this matter, as i don't want to go for that tyre again anymore and SVC people can change it any day.

Replies in bold

Hey brat, many thanks for the replies and the URL too. You looks like a pro in superbiking with your answers .

BDW i talked to gurgaon hyosung SVC and the manager told me that its not possible to put a heavier tyre without changing the rim. He don't even have idea of which tyre he will provide me in replacement this time. I am afraid that i will not be able to get my bike next week too, the way these people are serious and knowledgeable about GT 650R. Seems like i have to waste my day or two for all this crap now.

Urgent help required on SBK rear tyre change in Delhi/ Gurgaon area

Hey All,

I don't know if this is right place to ask my question but this is pretty urgent. A long story in short. I am from jaipur and i bought a Hysoung GT 650R from Gurgaon 2 months ago. It got damaged in a small accident 2 weeks back and REAR tyre was punctured too, while i was riding it on Gurgaon- jaipur highway. I got the puncture done from a roadside shop and gave it a run for 90 kms to jaipur. The puncture started leaking till the time i reached home and i had to keep the bike parked at home for 2 weeks after that.

After that i sent the bike to gurgaon by truck and the hyosung workshop guys there told me that puncture in tyre cannot be corrected and i have to get it replaced. The workshop manager and workers don't have any idea about new tyre, and proabably they will replace it will the same tyre i got with bike in starting i.e. Bridgestone battlax 160/60ZR17. This tyre is softer one, skids more on wet surfaces and takes time in heating up. Some one suggested me to go for a harder tyre and which can heat up faster like Michelin Pilot Power 160/60ZR17.

Now the real thing is that can anybody over here suggest me best tyre for my Gt 650R which can have better grip on wet surfaces and heat up faster. With this i need real help in getting the addresses of such tyre dealers in gurgaon or delhi. I am in jaipur and really i can't stay in gurgaon/delhi for more than a day for this work. I need urgent help as Hysoung workshop people can change the tyre any day.

Thanks in advance to all.
