7.5 amps should do just fine with a 5 amp battery...
that's enough and will work great..

take your time, and don't waste your leave for me, if in case you have an off or something then let me know, is all that i meant..


@remortr

gixxer already has a 195cc fiero, he doesn't need to downgrade to 180

its me who wants to upgrade to 180cc....

Smoked a FZ16 today, typical traffic signal drag, initially I let him go ahead and then whacked my baby, it overtook him effortlessly in 2nd gear, the FZ guy must have felt hopeless, I mean a 2010 Yamaha FZ bike getting beaten black and blue by almost a decade old puny looking, muscle less bike .

Hey Guys!!! How’re you all doing?!.

@NANOtech… bro it’s a real bummer isn’t it … to have some so close … so much expectation … and then …
Hey… it’s just a matter of a week … anyway your bike is running fine with the dazzling (actually blinding) headlights … so enjoy it till then.
And remember… When you do get it done, make sure you note down everything on paper … click many photos and show us the process with the entire detail… Make it real easy for a layman like me to understand.

About my bike… it is nearing the 500 km line … I want to run the engine for a little longer … about 750 km… but I too am getting impatient and want to change the chain sprockets and clutch plates and want the mech to do the necessary adjustments for a smoother ride. The engine sometimes feels very smooth … and sometimes it acts rough. I guess the adjustments and fresh oil might help. I am also feeling the gear shifts to be a little on the harder side these days… wonder what could the reason be. And once or twice the motorcycle has come to a halt … as if the carb has been overflooded or underfed … when reved quite hard … Any explanations guys!

No yaar its nanotech and next in line is probably vishalMaybe chiefashman would have gone for it too if he had known,there's always next time though.
bprags is already running this set up without any problems.So it's a much safer bet than my set up.

Firstly ,carbs don't wear out and they will out last the bike.Yeah, if you do put all the parts of the RTR180 like silencer,IDI unit,29mm carb .Then barring gearbox ,the bike will be near rtr 180 in mechanical terms.But still there will be performance difference as the rtr180 has bigger valves and a different cam
What you can do and what i intend to do in the future as well, is to buy the rtr180's head.Then get that head ported as well to make it even more better.As you know head has the valves and the cams.So the bike will be better than rtr180.That's for the future anyway and not planned for now.
Regarding the bigger carb.As i've mentioned ,i'm going for the 32mm one.But it will make the bike loose out a bit on initial and mid-range.So both for city use as well as performance, a 29mm carb makes more sense.

Had my first breakdown yesterday evening, but not an engine failure. Bike was standing in the rain for an hour, then refused to start. I suspected it would be the spark plug holder, and it was.
I removed it, cleaned the holder as well as pulled the spark plug out with a wrench and put it back, but still it didn't start. Had to leave it at my friend's building. Will get the holder changed at the next service definitely.
I know it will start in one kick when I go there this evening.
However, my area of concern is: The spark plug had black deposits all over it. What could be the reason for this? I'm running a 6-7K kms.old NGK Iridium spark.
Edit: I found this pic on the NGK website, but donno what mine exactly looked like, since I removed it in the dark I couldn't take any pics.

i wonder that its been so much of time and you didn't yet complete 500 kms, i would have done it in 2 weeks max...

the toughening of the gears will eradicate once you swap the oil..
also when you plant new clutch plates..

engine feels a bit harsh at times as it is still in run-in period...

get carb tuning done...
its a simple job...
there are 2 screws, one is called the air screw and the other is the fuel screw, both of them has to be adjusted to give you a perfect mixture which is neither lean, nor rich...

see it the spark plug is gone brown, if yes get it done...
if not then just ignore it and continue riding until 750 kms,
its too early to comment if something is wrong..

engine will turn butter smooth very soon, don't worry.

regarding my 180 stuff, don't worry high resolution pictures and detailed writeup will follow..

i hope i don't need to do all such stuff..
go for bigger carb and let us know the difference.
as you are planning to install a megaphone exhaust, isn't it illegal ??

hmmm
well i hope some good 600's are launched within next 2-3 years, enough of 150-180-200-220-225 as upgrades...
I'll extract as much as i could from this bike for 2 more years and buy a 600 later on..

How much has the engine done?Anyway to be on the safer side ,check the plug and if its not oily then there's no need for any concern even if its black in color.
To rule out further issues,try checking the oil level and then there's the simple method of checking the engine state other than the plug way.I am sure you are aware of it too.In neutral ,keep your palm a couple of inches from the exhaust pipe and rev the engine .If there's any oily soot left on your palm then the engine is in trouble.Meaning a valve train issue or bore issue.

Fiero already has a megaphonic silencer and it is loud too ,compared to the present noise regulations.It won't make much difference as i said the silencer is already loud so a bit increase in sound ,hopefully won't get cops attention.
I had done these modifications of removing the baffle and putting a bigger exit pipe and it wasn't too loud. In fact i had even put a Bullet's Rocket silencer too and had removed its baffle as well and my bike is of jelous and possessive type i guess How ? she(bike) burnt up the high heels of the girls who were with me on each occasion once when touring just outside the city limits and on the second occasion at madikeri a hill station When the first one happened it was just a day's trip and i got to face lot of flak for ruining her costly high heels The second one as mentioned was a 2 day trip and i was in deep s#$t as she was left in a limping state as a good 3 inch of heel was sticking to the silencer and to make matter worse when i saw it i couldn't help but to laugh at what the bike had done!! :So i had no other option but to remove the rocket silencer

@NANOtechnology Bro i done that job already & my friend done 180's kit to fiero Soon i will upload the pic Because the bike is far 50kms long from my native!

@ gixxer

ya ,man classic fiero is loud..
i realized it lately when me and vishal were riding together in city traffic..
it makes 2 times more noise than F2 and vishal really loves it... don't you vishal??

by the way, what's the size of karizma's piston, how much mm of bore are you running 65.5mm ??

how do you know that your bike is 195cc precisely ??
it can be more also imo

and what is the exact method of calculating the CC ??

@remortr

dude can you please give a detail as what PROBLEM the bike is facing, i can imagine as how good it could be, but bprags had initially said that "forget the fiero reliability after the upgrade"
just tell me where will i decline than the stock !!!
and don't forget to quote me what mileage your friend is getting with the 180 setup..

@bprags
same goes to you bro, tell me what are the bad points, and also the mileage..

------------------------------------------------------------------

NANOtech bro ... if you could please upload a picture of the BS26 Fiero carb and show me where the air screw is, I'd be a very thankful... I know the fuel screw ... the bronze screw (golden colored). I have tweaked that a bit... but tell me about the air screw... How to adjust, in which direction for more or less air intake and how to know if optimum setting has been achieved.

I will check the spark plug ... The last time I had the roadside mech check it (several weeks back) the mech said that the plug was smeared in some oil ... I wonder what that means ... he said it means it indicates "Time for a Piston change" ... something I had just done.

Funny thing is that the engine sometimes feels very smooth and responsive and sometimes it is rough and moody and refuses to respond to the commands.

----------------------------------------------------------------------

I love the sound of my Fiero ... a Classic one too. I find it a very reliable and soothing sound like from a powerful engine.

Even I want to know how the output in cc is calculated.

Classic Fiero is not at all loud. Who said so ?? . Its sweet music to ears man . I really LOVE the stock sound of the Fiero and I always(once in a month) put some amount of used engine in the silencer prevent it from rusting it then smokes for sometime and then all is well. The music is so good that you dont need any kind of K&N and all that stuff to change the sound.

forget the air screw, you don't need to dangle with it if you have a stock air filter..
you are right, the fuel screw is the bronze screw,
I'll tell you a simple process.

1- find a nice quite place and park your bike on main stand..

2- start the engine and adjust the IDLING SCREW to give atleast 3000 rpm even without holding the throttle, that simply means set it a bit high..

3- now with the help of a screw driver, tighten the FUEL screw a bit (bronze one) and observe the change in the sound, your bike will sound as if its struggling to keep the engine running...

4- do it the other way round, that is, rotate the screw in the opposite direction, at some point again your bike will struggle to keep running.

5- note that
IF YOU TURN IT CLOCKWISE you are providing lean mixture.
IF YOU TURN IT ANTI-CLOCKWISE you are providing rich mixture.

6- find a point by turning it left and right, where the bike sounds crisp and smooth and doesn't struggle and run at all.

7- after finding that point, slowly adjust the idling screw back to 1.7k rpm, or in simple terms, decrease it back to normal.

8- note that the bike should not struggle even when you adjust the idling screw to decrease the idling rpms if it does, then you need to adjust the fuel screw again very slightly to find that perfect point.

9- when done properly, bike will feel crispy and responsive and will give perfect acceleration across the revv band..

10- enjoy your tuned carb...
