General Bike Queries

[WildWeasel]

I understand its about the sporty look and performance. To add to this, better control on a bike too when we drive in a aggresive postion.

I am keeping away from these kind of bikes only because of the seating position. I prefer the RE's for the riding position though.

One more question:

I have heard some small blurps ( sounds like a small fart) coming out of the silencers? What is that sound actually? Is it some sound of warning?

Explain a little more in detail about these "farts"?

I dont know how to explain more. The sound comes from the silencer. I have seen this in bumper to bumper traffic in almost all bikes from 100CC to 150CC. Something like a airblock in the silencer .

That should probably be the carbon deposits on the exhaust getting bursted due to heat. Those are very much loud & heard well on most FFE's & sometimes you can even see long sparks coming out when they burst.

This is due to misfiring in the cylinder. If you follow a fierro first generation bike then you will hear this a lot. Even in old bikes or 2 stroke bikes this used to happen

Most ortho docs and PT's say that anything other than "sitting on a chair" position will definitely cause back/hip/shoulder problems in the future. So everyday bikers might have a painful retired life .
Have you guys tried riding while leaning back on something? It is THE most comfortable way to ride. Anything less than 90deg is gonna be painful in the future.

I am still not clear on what do you mean exactly?

Anyways, since you are hearing it on all bikes. Relax it must be normal.

Ya that happens, but we are not talking about FFE's. The sound that WW is talking about is from "Stock" exhausts.

I would rather have painful retired age than not ride now!

Praful - FFE was an example. Are you saying stock exhausts do not have carbon deposits & they do not burst?

Logical mis-deduction of a conclusion

When did I ever say the above part. You mentioned FFE's and that is not relevant to WW question, as FFE's behaviour is different from a Stock one..

[WildWeasel]

My question was not related to FFE or any mod. The ones i am talking about is on normal bikes. And its not an exaust note. It doesnt come often. Very rarely but i have noticed it in many bikes. So the question. Anyways it hasnt caused any problem for me because of that. Just wanted to know what it was and i got the answer. End of discussion

Now next question:

I heard from one of the mechanic that there is some fluid (2ML or 4ML) which if mixed with regular engine oil will help in reducing engine noise and increase engine life? Can someone tell me which oil is that? and Is it really usefull?

As far as i know the vivid bikers in our forum use only Motul Synthetic oil .Sadly i could'nt procure it for my spec.(10W30) Last time i changed, i used Shell Advance Ultra something Fully Synthetic oil.Though i have noticed the engine sound reduce, i felt there was a defninte drop in mileage . To aroun 4Km per litre.
Is it because of the oil or might be someother reason? Because this change happened just after my oil change i was sure its because of that.
