Hi guys,

me bought a FZ16 some 4 months back. The bike is amazing, has gr8 driving experience, has comfortable seating posture and its quite powerful. I cannot judge if its power is better than other bikes, since all I have driven earlier is a Pulsar 150cc.

My dealer told me while giving the bike that your bike is tuned at 4000rpm... what does that mean?

I believe the way we shift the gears plays a major role in bike's acceleration, speed, performance (mileage) and possibly its life (strain on engine).

What I want to know is, should I try to make go my bike on lower gears.. pushing them to higher RPMs like 5000, or should try to shift gears as early as possible to reach highest gear?

The bike can comfortably do the following:
Gear1: goes from 0 to 15
Gear2: goes from 10 to 30
Gear3: goes from 20 to 40
Gear4: goes from 30 to 50
Gear5: goes from 40 and above (max I have reached is 110)

is this appropriate? what would be the best speeds to shift gears?

Query Approved.

Its not the speed but the Rpm that counts . shift first gear at 3 -3.8 and rest at 3.6 - 4k Rpms for max mileage . drags are a different story altogether

1. Your yamaha dealer is stupid for sure. Setting or tunning the byke at 4000RPM means he kept the byke @ 4000 RPM and then set the AF screw... Dammm FZ is air cooled engine not liquid cooled. besides In two stroke engines tunning n setting is at high RPM but only if the workshop is equipped with air blower. (I hope ur engine is perfect )
2. For setting AF in four stroke single cylinder, AF turns are given by company end. So no need to set @ 4000RPM.
3. Changing gears at particular RPM (as per your
Gear1: goes from 0 to 15
Gear2: goes from 10 to 30
Gear3: goes from 20 to 40
Gear4: goes from 30 to 50
Gear5: goes from 40 and above (max I have reached is 110)
is not possible all the time. The gear shifting is depending LOAD, RPM, TYPE OF ROAD, HANDLING etc. etc..
If manual says that shift the gear at particular RPM, then u can't do that all the time coz thoes RPM charts are under normal condition.
So I think u ride the byke normal way without streatching or giving load.

I seriously hope that your bike's idle tuning is not set at 4K rpm. when you are starting your bike for the first time in the day check the rpm position without engaging any gear. That is you idle rpm. About gear shifting just follow what Puneet said.

alrite, when the bike is idle, the RPM meter says 1000, it keeps jittering arnd 1000. is that fine?

then what did the dealer meant by saying its tuned at 4000rpm. Did he mean that 4k rpm is the correct limit to change to higher gears as what puneet is talking about?

shiben

alrite so i get it, upping the gear at these rpms meaning straining the engine least rite? thats y max mileage.

and I believe, by saying drags are a different story, u mean that I shud try 2 achieve max rpms at each gear and then shifting up.. rite?

@Chinmay Dangre its true that its not possible all the time, depends on load and road both
the speed I have mentioned are tested by myself. sometimes going 2 5th gear is not even needed on the bz way 2 office as the traffic doesnt move faster than 45kmph itself. however turns out its may not b appropriate for mileage as puneet says, shud try 2 focus on rpm more than speed

Puneet1

yeah least strain for max mileage , but shifting too early is also harmful .
for drags you have to shift where your bike engine gives max power .

At 45 Kmph you should be around 3.5k + rpms so you can be on 5th gear but if you need power 4th is the way to go

Well,simple rule about shifting gears at right rpm is whether you want good power or you want to stretch your mileage. Shifting at lower rpms into higher gears improves mileage shift too early and it will take its toll on the engine. Also, chain wear will increase as you are asking the bike to pull w/o sufficient torque at the crank.

Check your bike's engine specs. For good 'pulling', shift at the rpm when torque is max, maybe in the 4500 to 6000 rpm range. For drag like situations, shift at max power rpm i.e 8000 - 9000 rpm. Also, for drag like accelerations, better to shift w/o using the clutch. Even the Shell website recommends shifting up w/o using clutch as it decreases wear on the clutch plates. May take a bit of practice to get jerk free shifting. Also, always remember to use the clutch while down shifting
