I would definitely agree on that , but using an R15 sprocket on an FZ will change those characteristics a lil bit won't it ? like the initial pick up and top end ... that was all i was trying to say .

Sure will, but I wouldn't mess with the wonderful mid range power delivery that the FZ gives!

firstly dude...all of us here are frnds ...so chill with the sir....

the changes would include the widening of the rear or extension of the chasis...not sure..havent thought bout it...dont even fully kno if it can be done....ask in the mods thread is wat i would suggest....cheers....

actually the rear seat is very small to seat comfortably, so i jst wanna put some xtra pad on it.........

anyways thank u sir ........ oops dude

widening the rear seat? i guess that would require a wider framework and that would involve bending the rear framework of the bike , making it that much more prone to failure and also really mess up the dynamics of the bike , handling will take a hit ... also weight distribution has to be taken into effect , the chassis may not take the extra weight ... all in all , i would suggest not to go with the mod ... jus my opinion .

or you mean jus adding some extra padding to either side of the seat to make it wider , which i'm thinking you do , then yeah the looks will get ruined .

ya i m thinking of it only, adding some more pad or put a spilt seat will be a better option......... can u hav any idea of it ??

I'm not sure a split seat is possible for the FZ , but i guess padding can be added to the seat , you can get that done easily although i doubt that it would be any more comfortable , because the seat's framework may not be suited for the extra padding , i guess if uadd some padding on top it should be ok ,rather than on the sides ... hope this helps ...

hey going by your definition , the FZ16 has a smaller rear sprocket than the R15 right ? 40 teeth to 42 , but the smaller sprocket in the FZ gives more initial acceleration and lower top speed when compared to the 42teeth sprocket of the R15 which lags a bit initially and as we know , then comes into it's own after 6k RPM . ( read greater top end ) , this now , directly contradicts what you've said ... NOW i'm confused .

You can't compare the FZ with the R15 since they have different engines. It would be like saying two people of the same height can ride bicycles at the same top speed. The riders' height has no relation to their strength.

First, some technical info:
Final drive ratio on a bike = number of teeth on driven sprocket divided by the number of teeth on drive sprocket

Note: High ratio = Low gearing, in familiar terms

Increasing the ratio will increase the torque available, thereby increasing acceleration. But since the engine speed is higher for a given speed, top speed reduces. The inverse is also true.

If the ration decreases, the theoritical top speed changes but the real top speed is limited by the amount of power generated by the engine.

From my observations, it would be good to have a 6th gear on the FZ instead of decreasing the drive ratio of the 5th gear. With a 6th gear that's higher than the current 5th gear, all the lower gears can also be lowered just a bit to improve driveability.

Pardon the ignorance bro , i am not as well versed as you probably are with the technical details , but i drew the inference based on what you had said and the general observation of the performance characteristics of both bikes ... peace .

has anyone put crash guard on fz?

**yellowspunk** · 01-15-2010, 08:00 PM

my fz tyre pressure stays only for 2 or 3 days max. there are no punctures. any idea guys?

plenty of ppl have..it doesnt look good but provides the necessary protection...available for Rs 600....

check the valve.... maybe it is faulty...

I totally agree with you buddy.... i do feel the lack of a sixth cog on the
highways.....it will improve driveability a lot(not that its bad now)....
But we can only wish....cheers...

fazer engine heating

i own limited eedition fazer
im havin a new prob with my bike
my bike clocked 3918km and jus nw i noticed that my bike's engine is gettin xtremely heated up after short rides of 4 to 10 km
speed around 50 to 60,i showed at the svc they said this is normal and after heating upto a certain extent the bike wont get heated up but my local mechanic said this isnt good.the svc guys also measured the temperature of the oil and it showed 85.5degree celsius they showed me a book and there showed idle engine rpm temperature is 75-85degrees.so i changed the oil yesterday but no good.so i wanna ask u if u have the same problem????
before the 2nd service before 3000km i havent had tis problem
wat shud i necessarily do to prevent this???
or else is this normal??
awaitin 4 ur reply

**k2cool_87** · 01-15-2010, 09:38 PM

the engine on the fz is air cooled and in traffic does get heated up...wat oil did u change to ? is it mineral or synthetic or semi? also depends on the grade of the oil and whether its according to the current season....

Your inference was wrong not because of an incorrect thought process but because of insufficient information. Only natural.
