Thread: Fiero/FieroF2/FieroFx

Hey guys, i have been facing a slight problem with my F2's rear drum brake!!

while i am riding, if i apply a slight pressure on the rear brake foot lever (there is play, so does not engage the brake), i get a feeling that the pedal is moving up and down like a harmonic motion..but when i actually apply the brakes, the application is smooth, i mean no up, down movement of the pedal.. What could be the problem? i checked that there is still enough life of the brake pads, its has not yet worn out....

And also, for the past one month, i have been travelling almost 120kms everyday, comprising of highway rides (hardly 15kms of normal traffic rides). i only get a avg of 48 - 50 kmpl if ridden at 55 to a max of 65kmph.. now, is a OK OK avg that i m getting considering the age (8 yrs) of the bike and the total kms it has done (over 1 lakh) kms?? And what has to be done to increase the avg? And will there be any outcome if i get the tune-up of the carb done for this old bike?

Check your wheel and sprocket bearings.. your rear wheel might wobble creating this feel... 48-50 on a lakh old bike is really impressive.. Don't expect more from her.. You can run your bike without any engine rebuild until you get white smoke in the exhaust..

Seriously, I feel that if you're getting around 50 kmpl, then you shouldn't be complaining. That's pretty impressive for the age and condition of the bike. I don't think many here with 7+ year old bikes are getting that much. I'm not.

You may want to get the rear wheel bearings checked to eliminate that up down or sideways wobble. And just as an outside chance, see if your rear brake spring is fine which switches the brake light on. Or check the mounting nut of the brake lever for sideways play. Maybe uneven wear on the inner drum brake liner? Even the brake rod may have developed some slight flex.

Dear Friends,due to requests from some members I had started a new thread on LOCOMOTIVES explaining their growth from Steam to Diesel Electric to Electric..It is posted in Coffee Lounge OFF TOPIC Discussion as "AN Intro To Locomotives"...Those who are interested can visit the thread and can raise queries to clear doubts.

Guys, yesterday i found out that yamaha libero has the same digital cdi(the socket) as that of a fiero.. Libero stroke length is 56mm and ours is 57.8.. Are cdi units are same?? Do u have any idea about it??

just got my bike from service today.....

Fitted in a RTR 180 chain sprocket, had to change the rear bearings (all 3 of them), 2 bearings were completely broken, while the third was intact.!! Now this has eliminated the rear brake pedal up down wobbling!!

Now the thing i noticed about the rtr180 sprocket is that, the initial pick up in the 1st and 2nd gear has improved a lot...while the top speed may have come down (which anyways i am not interested in btw). the thing that really amazed me is that the bike pulls in very easily if the speeds are as low as 25kmph in top gear without jerking/knocking. hence this factor reduces the frequent down shifting of gears which i used to face in the normal f2 chain set... Hope this increases the avg of the bike....

and also i would like to know how to keep this chain well maintained since its a proper open chain o ring type chain... as u all know my daily running is 100kms, so after what intervals should i lubricate it and which spray is suitable and readily available in the market?

Use the TVS Tru4 chain spray every 5-700kms.

Thnx Sarvajit for the quick response!!

the RTR 180 uses a 46 teeth rear sprocket while the classic fiero(don't know about f2) has a 39 t rear sprocket.. So you have gained a good acceleration.. But your bike's avg will drop atleast by 3-5 kms.. For cruising, this might be a headache.. your bike will want another shift..
