    I run an Original 8hs on my stock setup and it feels quite different from a 7hs but Can't say if better. So i have reverted to 7hs.
    Thanks for the clarification. So my understanding is there is nothing wrong except cold start and slight difference.

    Though going to take the above suggestion to use 7HS, still I'm going to give a try and see what exactly happens for a day or two.

    4speed: 7HS
    5speed: 8HS

    Note: aware of Fake 8HS floating in the markets,NGK does not supply 8HS to the indian market
    Thanks Arvind for the response.

    Please find my stupid question below:

    Still wonder where it is written that 4 speed - 7HS? If you can direct me to some source of information would be much appreciated. I can start cursing Yamaha Motor India for misleading information on Owner's Manual.

    I bought a spare 8HS plug from Paras Yamaha (Y.A.S.S) little over 8 months back.

    I think shogun came with 8HS too.

    Thanks Sandeep/Pradeep for your valuable inputs. I had asked this question since the manual said so. After reading above posts, it tends to ask me another question, what does 5 speed owner's manual say is ideal (I wonder)? Is it 7HS or 8HS?

    If 8HS is a colder plug, does that mean would harm my engine in the longer run? Don't we agree that we should go with what company recommends?

    Although these days, I was only given 7HS from the Y.A.S.S when asked for a plug saying this is what is recommended.

    My objective of bring this to discussion is to find out the deviation from the company's recommendation and the pros/cons.

    In general car engine oils will have certain "friction modifiers" which are meant to reduce friction ... this can be disastrous if you use it in a wet clutch multiplate setup on our bikes. So be a bit wary of car engine oils.

    30ml is ok. Its normal I would say. But it seemed to be running excessively rich. Hence I suggested to carry a spare plug in case you foul this one.

    Hmm...Ok give me atleast a 500 Kms run to make a concrete report on this. If there's a clutch slipage, then, I'll swith to what Sri says w.r.t Motul.

    I happened to flip through the Yamaha RX135 Owners Manual today. I saw they have suggested NGK BPR8HS. However, the service centers have and recommend using NGK BPR7HS. I wonder why there should be a change?

    I somehow found a used plug NGK BPR8HS with me and checked for the spark. It is good. However, thought would let everyone know of the fact.

    Can we discuss this?

    Haha...I took AGIP Diesel Engine oil as I could only get that. The guy also offered me 4T on Shell, but I did not consider that one. I choose AGIP Diesel because of my previous experience from Castrol CRB & Yercaud trip. I'll post the pic of Engine oil tomorrow.

    Meanwhile, the update I posted in the morning are...
    1. Airfilter cleaned up using Rin & Surf & sprayed 2T oil. The result is amazing. I've the pic & will post tomorrow.
    2. Washed (rather wiped) using Sonax car shampoo & applied Waxpol on tank, swing arm & L brackets

    The only pics I've to post are AGIP, air filter after cleaning with rin/surf & then applying 2T oil.

    Trust me, the result is excellent to clean the air filter with rin/surf & soak in 2T rather than cleaning the airfilter using petrol. Amazing thing is that the wrinkles are gone now & looks like brand new. I'll post the pic tomorrow.
