Re: Yamaha FZ-16/ FZ-S
Originally posted by nadz11.ns View PostThis statement isn't correct.
During power stroke, both the valves are closed and there isn't any force to push the air in reverse through the air filter.I'll rephrase :Originally posted by arijitmaniac View Post...
Air is never pushed out during the power-stroke. The air stays inside the combustion chamber and is compressed by the piston. This high-pressure air-fuel mixture on ignition generates the force to push the piston down.
If the air were to be pushed out then the pressure would be very less and therefore the air-fuel mixture would not have enough energy to push the piston down for the next stroke. In other words the engine would stop.
It is to maintain this compression that we replace the piston-rings, valve-seats, valves, head gasket etc when they are worn out. Hope it makes sense.
...
- Displacement of the engine is 153cc, so effectively about ≈153cc of Air-Fuel mixture is drawn in during intake-stroke. Similarly ≈153cc of burnt air-fuel mixture is pumped out during exhaust-stroke.
- Piston, piston-rings coupled with oil-film on the cylinder wall effectively create a separation between crankcase & combustion chamber.
Now the discussion was regarding crankcase-breather-pipe, which has effectively open ends for free flow of air.
Do you disagree that piston displaces 153cc of air in crankcase with every stroke? Effectively aerating(153cc) the crankcase twice every cycle in 4-strokes.
PS: What about left overs gases after exhaust-stroke, not to mention fumes from crankcase-breather-pipe.There is no honest path to prosperity - KoKa

Re: Yamaha FZ-16/ FZ-S
Yes you are correct @SparKot warm air is less dense than cold air, hence does not assist in better combustion. I stand corrected.

The problem with grease is that it does not stick to the chain. Hence it is removed during the ride and it is also assisted by the rain which still worsens the situation. Like said before our chains are O-ring chains and normally does not need lubrication between links as the grease is sealed inbetween. But for smoother movement of the chain over the sprocket some amount of lubrication is required. That is the reason chains sprays are sticker in nature. They stick properly onto the chain and form an thin layer of lubrication which will help in a smooth movement of the chain over the sprockets. Many people miss out on one factor during the chain lubrication is the pre heating of the chains(i.e) ride the bike for atleast 10 to 20 mins before applying the chain spray. The reason being the chain spray clings better to the chain when it is warm.Originally posted by nadz11.ns View PostOne more query, would it cause any harm to the chain if i apply grease meant for industrial use ?
I had cleaned and lube the chain last evening but had to ride today morning in heavy rain for nearly 2 hours. The chain started making weird noise and upon inspection saw the lube had washed off and it was having metal to metal contact. Don't have any oil or lube at present.

And yes, the external lubes we apply is only for the smooth movement of chain on the sprockets and minimize the outer wear of chain and sprockets.
Btw, this warming of chain is new to me. Would try and see if it holds true.
Ride safe and have fun.

Re: Yamaha FZ-16/ FZ-S
Sorry I missed the crankcase there. Yes that makes sense. I guess this is the same pipe. Maybe the crankcase is internally connected to the header and this is where it comes out.Originally posted by SparKot View PostI'll rephrase :

Because someone has scraped a part of swingarm on the left side and it looks bad.. Soon I am planning to get a paint job done so I will replace the swing arms too.Originally posted by kusmaker View PostWhy are you replacing swing arms of Fz.

If it's just a scratch created by the scrap and it's not bended, then you can just go for repaint of the swing arm no need to change but if it's dented or have gotten bended then certainly change it ASAP.

What work are you getting done? Looks like some major overhaul in the bike.
Cheerz!!
The clutch plate price is mentioned as 790 - 10 th item in the list. When did you last check the same?BENEATH THE REMAINS.........

Re: Yamaha FZ-16/ FZ-S
Since the SVC is on my route to office, I go and ask personally or call them. AFAIK, the rates should be same across India.Originally posted by chaosaddict View PostOh crap, that's a good difference of 100 bucks. Any link/ref. as to where i can get the price list of genuine spare for fz
