As i said ,like my favourite goddess who personifies love,natural beauty,fertility and aesthetics .The himalayas are beautiful, like her full of curves.They just like her will make us men into her lovers and inspire poets.I will never forget the journey bro,travelling on top of the bus was an amazing experience.Truly like her there's no mountain range on earth as beautiful as the himalayas.

Wise decision bro ,stick with stock gearing.If you don't mind wasting 100 bucks you can try it out though.Valleys are the places where civilizations are born bro.

Get the head work done buddy ASAP ,porting is optional though.

SPOT ON!! not forgetting the coil are we?!!!

Hope he does it,and saves his motor.

Nothing like that. I am a noob.
Its just that I did a bit of research before settling for these Michelin tyres, so I know a bit.
Btw, now my R15's rear tyre has 5 punctures plugged!
Its time to change, but Goddess Lakshmi is kinda upset with me these days.

@abhilashabhi12: I found out-the rim you have is a 2.50" wide rim made for the Classic Pulsar 180! Have a look at this site: Indiabike.com - Overdrive Roadtests - Bajaj Pulsar 180 / 150
If you put a 3.00*18" tyre it will bend the rim from the sides.
You need to look for a 100/90/18" tyre only.
Following are the options I would suggest in 100/90/18" size:
1. Michelin Pilot Sporty (best for tarmac usage)
2. Michelin Sirac Street (On&Off road control)
3. Dunlop GeoCruiser (you know very well about this one)
I would not suggest the Ceat/any other button type tyre as they are heavier&bring down the accelaration of the Fiero.

Which coil?
I'm yet to go to an auto electrician.
I guess it will finally get postponed&we will go to Ruby together only.
Maintaining 2 bikes itself is this tough, I wonder how it will be if I get a third!

As some one participating in this thread, I had noticed that with only 166 pages and 1656 posts....the forum is turning out to be highly technical,and the sharing of technical information is phenomenal. I don't think any other forum is so consistently sharing,and doing so much mods like this one.So much knowledge about engine, electricals,and tires are exchanged here......I am happy to have come to this forum and had gained knowledge here..Many thanks to everyone.

M45 at front often wears out unevenly. Have seen it happen with different people, riding diff bikes.
M45 at rear easily lasts 24,000km's, all my M45's at rear lasted at least that much.

I think now you know that it is actually 2.50x18, this rim is bad ass rim, MRF zapper Y 100/90-18 contact patch is almost 95% on road fitting on this rim.

Coming to F2 top speed, I haven't driven an F2 until now but I am sure it can do well since it is based on same engine as Fiero, with 14t IMO you can easily 80kmph if not more & yeah do check on that W30 grade engine oil you are using now becuase the thinner the oil the more stress on engine on Higher revv's & In my experience thinner oils do not perform really well in long distance touring

I think I have made up my mind, I will be sticking to 100/90-18, I got a link yesterday in which they have clearely mentioned all the possible rim sizes for specific size tyres & the minimest possible size can be put on 2.50x18 is 3.25x18, I dont wana play around with it so will lug around with Zapper Y for some more time


@ Sarvajit

thanks for advising on tyre size, I will stick to 100/90-18 & my zapper Y seems to can lug around another 5k if not more, so Until then I will decide on which tyre to go for, I always liked the button type & I know the beauty of Geo Cruiser, my heart says go for Dunlop Monster same tread pattern as Sirac

I am confused as of now

Previliged to be a part of this thread, of all the ownership thread I have seen in xbhp, this one here has the most technical debate posts & sharing of knowledge

The Sai-Iyengar guy is BSing about 3.25 not being available, I have used that tyre for close to 3 years, excellent grip, 3.00 * 18 is too thin and 4 * 18 is an overkill for the Fiero. 3.25 is perfect, hunt and get it.

Man, I would advice you to throw that tyre away, even if they give it at free of cost. In colder weather expect the tyre to perform still worse. It is the worst tyre I have ever used in my over a lakh kms of riding the Fiero.

+1 to Nav. I have seen two M45's on my front wheel showing uneven wear. The best I have used for the front is the M35 2.75 * 18.

Hmm, that is good to hear. I could have got M45 for the rear too, but I chose the Sirac. Though it is a 3.00, it looks slightly bigger due to the button profile.

Yes, I think it was the largest one in its time, since the CBZ Classic, which also came with a 100/90/18" tyre had only a 2.15" wide rim!
That is why putting a smaller tyre will not suit.
However, the mileage&accelaration both must have taken a hit due to the heavy rim.

Though the engines are similar, there are a lot of changes made for the F2. Fiero puts out its peak power at 7.5K RPM, whereas F2 does it at 7K RPM. The exhaust note, engine refinement at lower speeds etc.all are different for the two. Gixxer says Fiero can do 118kmph in stock form. I have never seen my F2 going beyond 110kmph even when it was new!
As for the oil, it is the first time I'm trying out this Tru4Premium semi synth oil. Till now I have been using 20w40 mineral Tru4.

Ok, make your choice when the time comes! Button type in Michelin will be the lightest, followed by MRF, Dunlop and finally Ceat. I feel its better you rule out Ceat, as they are really heavy. As it is you are running a heavier rim&a bigger tyre size. Accelaration has already gone down. If I were in your place, I would get the stock rim, put a 3.00 tyre&enjoy the bike lifting up every now&then!

I have discussed this with GoGreen also-I think the tread pattern is the culprit here which gives an impression of uneven wear. Moreover, it doesn't even have a central groove unlike the M35.
Too early to tell in my case. If it is not good, I will go for the M35 next time!

Let me summarize the tyre recommendations

Front
M35 2.75 x 18.

Back
3:00 x 18 Sirac Street.

is that right?

Yes, if you are interested in the central groove, then M35. Else M45 for the front.

With more than 5 years of Michelin usage I would say use M35 for the front and Sirac for the rear

It's not me man .It's been proved on the chennai race track by OVERDRIVE when they did track tests with stock bikes and had asked a TVS race team rider to ride the STOCK FIERO and the fastest bike on indian roads ,that is bikes made in india was the YAMAHA RX 135 5 Speed and the next fastest was the Fiero which clocked the mentioned speeds.CBZ and dtsi Pulsars were slower.The track was wet at that time and the equipment used for testing was heavy one which needed to be strapped on to the pillion seat and the riders were told to take it easy on the lap times .As the track was wet and the equipment costly.

They had taken the corner entry and exit speeds also,it was first done by the OVERDRIVE tester Aspi Bathena and the best times were set by the racers later.Once again on stock bikes used by OVERDRIVE.

The track's straights are short,so a stock Fiero will hit more than 118 kmph on longer stretches and actual speeds not speedo indicated ones.
