Guys you wont believe what happened today. I went to the showroom from where i bought my bike to take the manual. I saw the showroom manager busy showing the showroom and workshop around to two Chinese or Japanse ( i dont know how to differentiate between them ) people. Then when i asked the manager she told me those are guys from Yamaha Japan R&D. She asked me to talk to them and bring out my queries. So i said Hi and started talking to them asking them about the engine oil. I couldnt really make out what they replied back in English. It was in a Japanese accent. Then they asked me how is the performance of the bike. I told them that the handling and feedback is just brilliant. Especially on corners. You woudnt believe it but they felt as happy as a 2 year old child would be if you give him a chocolate. I never expected Yamaha Japan R&D engineers (this is the same team that also designed the R1 if im not wrong) to be so down to earth and to get happy just by listening to a few good words about their quality product. I thought they already knew how good the bike was. They were thanking me a lot and then they asked me to provide some feedback on the bike. I said it could do a little more with low end power and a more powerful low beam light. To this they nodded in agreement and talked in Japanase for a moment amongst themselves and they also noted it down in their notepad. Then came one of the best moments of my life. They asked me if they could take a photo of me standing beside my R15. I never expected something like this to happen in my wildest dreams. I think you people can already guess the feeling reading my post.

Whatever.... I could give you an answer for each and everything that you have pointed out in your post... but it will only degenerate into an argument which will have no head or tail.... so... to each his own... peace brother

I was going to a friends home and I tried to start my bike but there was no display at all, tried horns, lights everything.. nothing worked.. I tried to push start the bike but it wont start as my central locking was on and without disamring it it wont start the bike. It just gave a beep.

What should I do guys?

I checked the fuse and its fine, not blown.

Edit: SVC guys came and checked the bike, it seems there is a wiring problem.. I'll have to take the bike to SVC tomorrow. What could be the problem? The bike was running fine till last night, it rained today, can that be a issue?

@mach50 - The figure of 17 bhp by the company is attained on a set of test rigs ( read engines ) If you read the manufacturers submission documents for approval ( which i have ), It will give an indication of what the tolerance is, and how many engines are gonna be tested out of a batch.

Generally the power produced is given a 10% tolerance. Which means, in case of the R15 it can be 15.3 bhp to 18.7 bhp even!

10 out of a batch of 100 engines are tested to within these tolerances, and yes, the lower out put ones are also installed, unless there is something drastically wrong with the engine performance.

So if you are running in your bike using a varied method, yes there will be a difference in the power output after the running in has been completed.

I just got the can of motul chain lube and chain clean for Rs. 761. It is the dealer price in Lucknow. Has anyone purchased it on DP and is there any difference in DP in different places???

I purchased the motul chain lube (not the chain clean) for Rs480 from karol bagh,Delhi. What's the mrp of the motul chain clean?

Guys,
from the First service onwards i am using the semi synthetic oil, but To be frank i never knew the difference between a Mineral oil and Semi Synthetic oil. Could any one here Please shred some light on this.

Also mY bike now a days feeling some what Rough now, Clocked 5000 Kms., is it Due to the oil i use?

Also i badly need to lube my Chain as it is Dried out. some sound is heard while i accelerate, i believe it is because of my dry chain.

So what are the negative if i don't lube the chain properly?.

You got a sweet deal! I hope you've checked that the cans aren't very old.

For diff b/w mineral & ss oil, pay a visit to the Engine Oils thread.
Roughness depends on the distance which the oil has run. Did you check the oil level using the dipstick method?

Don't run the bike on a dry chain. If you do not lube the chain, it will cause the O-rings & the links to go bad, & will result in roughness in drive & power output. You will end up damaging the sprockets too!!
Invest in a chain spray, & DIY everytime the chain appears dry, & especially after riding in the rain.

Thanks Tibby for the quick reply , Got it Lubed today from perfect riders. They chareged me Rs 135 . i have to get a chain lube and clean as early as possible.
