personally, as i have already mentioned before.. the so called warranty is a marketing gimmick. it doesnot cover consumables or moving parts like piston rings and the piston, clutch plates, electronics etc. they may change the engine block should it fail or say the piston valves and rings if they fail during run-in and that's about it. Had a along chat with my trusted Kamla Yamaha SVC boys and the SVC head mechanic over what parts would the SVC cover should anything ceases to function during warranty.. so basing my answer on that.

FFE upgrade doesnot damage the engine as per my experience which has been thoroughly archived on this thread. Unless one just simply keeps the engine on the redline for extremely long durations which even on a stock mid ship exhaust will yield the same damaging results.

@Muztariq: Isn't 10W 40 oil a bit too thin for the temperatures he mentioned? i would personally recommend 15W 50 in this regard. Have tested it to temperatures of 3'C (leh test is pending ).. works just fine and doesnot vaporise or reduction of engine oil level till almost 4000 kms if i remember posting here correctly. I think i did a top up of only 30ml that too just as a precautionary measure. Engine cranks to life without any glitch.

Cheers,

Bro u can go for performance mods....but wait for the free services to be over atleast... And if u have good rapo with the Sc people then even after doing mods u will get warranty ..---*terms and condition applied
U can use the water pressure u have bought...but remember dont use it on the discs... dont use on the spark plug area and dont use it near the exhaust vent and the display pannel...Thats it... and bro i requested you to upload a video...did you forget?

Hello @toxic biker bro even my babe is 9 months old.. Had already done electrical mods... never touched the mechanical part as i am quite happy with it... just wanted a little more grunt from the exhaust...

Yes bro as i have mentioned earlied to you that i am using 15W50 SS. so just upgrading to 15W50 FS will do? And as already mentioned that i have seen friends using 10W40 resulting in lower engine oil levels almost less by 400ml. within 2000kms. so was just confused though the quality of Motul and castrol is like heaven and hell... Some days back read a document saying that 15W50 works good at temperature from 0 degrees to 45 degrees... but isnt 50 thicker than what is recommended(40). at higher temperature 50 will be thicker than 40 resulting in resistance.. isnt it bro...

What has been your experience with the SS oil from Motul so far?? are you satisfied with the result? it is single ester based SS oil. The 300V FS oil 15W 50 is double ester based oil and can handle high stress environment and higher temperatures much better than other brand oils. I have used this rated oil till the temperature mentioned in my previous post.. without hiccups, or engine oil reduction or any problem till 5000 kms. Abhimanyu31 swears by that and so do i.

If the engine oil is too thin at higher temps the film of oil covering the cylinder area will be very less resulting overheating due to friction between the surface. Although i would like to request Muztariq to throw a light on this one. 20W 40 is based on mineral oil rating by the manufacturer as per my chat with the SVC head. and so far after 8000 kms of using 15W 50 rated
oil from Motul i am very satisfied with the result.

So personally 15W 50 is fine by me and would be my recommendation. Castrol unfortunately has a lot of fakes in the market hence, not recommended. Motul to confirm the genuine product you can directly get in touch with the Motul guys and they will direct you to their authorised dealer or if you are based in a major city can try and help you out getting free delivery at your doorstep.

Cheers,

Just keep in mind, You choose your oil weight with the temperature you expect for the life of the oil.

The higher number is what your oil's viscosity will be when you start your engine up cold.
The lower number is what your oil will be when it is hot.

So, if the temperature is going to be hot, naturally the oil in your engine will be close to ambient temperature u should choose the higher number.
Cold temp you would want a lower number (eg 40)

Once your engine is warmed up the oil will be 10w or 15w or 20w.
Even if you have a high number eg 50w and it is cold, Just start the engine, let it idle 30seconds or so to get the oil flowing around and then begin riding slowly. After a couple minutes the oil will be up to temp and you are good to go.

Just don't be so quick to change oil viscosity, brands. Better off picking 1 brand and keeping to it. Different oil companies use different ingredients in making their oils.

no bro, it doesnt happen like this.. The numner before W is your cold start reference number which helps in selecting where you want to start the engine and the number after W is the kinematic viscosity the oil will attain when at 100 deg celcius(operating temp).

Please go through the engine oil thread.. Detailed explanations etc are given. Even big debates which went on for months.

Are you telling me that hot oil gets thicker? and cold oil is thinner?
Wow thats news to me!

@all: Thanks for the help.
@Toxicbiker: I have pressure-washed the disc only once.Won't do it anymore,it needs a cleaning though.The SVC never done it in 6 months. Rear drum brake has been cleaned,though. Need to meet you,man.I think my ride has lost some of its smoothness,thanks to some changes in clutch settings by the SVC.Not sure,hence need some clarification from you.
@Raj157: Used the thing only once bro,will upload a video soon.Thanks.For the time being,u can see the video which inspired me. Why don't we wait for a few more days and order a pair of FFEs from Joel?

i didnt say that.
Number before W should not be confused with actual viscosity.
Number before W is 'cranking viscosity' and number after W is 'kinematic viscosity'.
We have had some excellent discussions in this world about engine oil. Thats why asking you to goto engine oil thread.
Typing everything here would be wastage of effort, as it is already documented there.
You can goto the link provided in my first post here :

sorry bro but i dont want to use joel's.. He has done rrreally a commendable job... but i dont like the design at all...if he comes up with a good design and material to build... i will definitely opt for it... but until then,m happy with stock.. just want to increase the bass of the exhaust. thats it...

Thank you bro... so in cold i.e winter i can use 10W40 and in summers i can use 15W50... ofcourse motul 300v and nothing else will do

lets agree to disagree and move on. I'll choose my oil in a different manner without needing to know all the scientific refining processes.
I just help get it out of the ground for the oil companies

Amazing Mod

Guys, found an amazing mod.. The exhaust note is great and the Acceleration is outstanding!

OT!?

OT,but hilarious...I was seriously expecting an RX100...
