road_ripper : R15 tyres can be fitted on P180 UG3 with out any issues.. You may loose the top end my small margin though.. Since the thickness(height) of stock tyre is 90mm and that of R15 is 80mm..

voodoo_god13 : You for sure should feel the difference in performance, since R15 tyre is just 80mm(80% of 100mm) heigh compared to the stock 96mm(80% of 120mm) of P200.. Pick up must have increased and top speed should have come down..
Also with FZ rear the ride quality will be better than with R15 rear, since it has 84mm(60% 0f 140mm) side wall.. Also it being very broader tyre in a smaller rim makes it stay more rounder adding to the efficient height..

Right Spark Plug

Came across something real strange last weekend. Not strange actually

Some of you may already be knowing about this.

I cleaned the spark plugs and then before fixing them back checked if it was supplying current. The one on the left sparked just fine, the one on the right did not. I kind of panicked for a moment but thought it's either the ST Coil that's gone for a toss or the CDI.

So without any prior knowledge did a little Jugaad. Got a copper wire and tapped the left ST Coil to the right and walla, sparking was just fine. I came to a conclusion that prolly it's the CDI. Yesterday I went to Gems Automobiles (here in Pune) and spoke about this to the mech there.

After a smile he said, "Bhai right spark plug gaadi chaloo hone ke baad he spark hota hai." (Bro the right spark plug opens up only after the engine is running). He quickly got rid of my jugaad work, cranked her up and boy was I glad to see her sparking just fine

Just a small experience for your information!

@vinal22 I expected the same before putting on the tyre, but there is no change. It even does sppeds at the same RPM i.e. 80 at around 6000 and 100 at around 8000. I guess the change is negligible so I haven't noticed.

Also to get more out of the bike I feel weight reduction is a good place to start(if you don't care how the bike looks that is). I have no trouble beating my friend on his 220 just cos I weigh a lot less than him. I will try this out next month as well and see how it goes.

The speed/RPM reading will not change as your front tyres are stock. With the R15 front they will go haywire. You'll be seeing highly optimistic speedo readings that is..

and your odo will be covering kms faster (which also means you reach the end of ur warranty period faster).

I was mentioning the RPM bit cos I was talking about performance. As in how i did not feel any improvement in pickup with the less diameter of the back tyre.

I am expecting a speedo error. Any idea how much though.
and I'm not too bothered about the warranty, I dont expect to own this bike much longer another year perhaps. I'm gonna have fun with it while it lasts.

Ofcourse it can!! i have touched 127 but was seriously scared with the rear wobbling

there was video link in this thread a stock p200 touching 141 !!!

**Full Throttle** · 03-18-2009, 03:05 PM

Do you think is it a speedo error, or it can actually touch that speed...........

Hey, The Speed/ RPM is also dependent on the rear tyre man not just the front tyre...
The rpm hasnt changed too much for a particular speed as both of them have almost same dia tyres.. (120/80, 100/80) as the 80mm dia of the tyre remains same, there will be no change in the rpms

When you see a reading 120/80 on a tire, it means the lateral (side ways) thickness is 80% of 120mm (which is the width of the tire)

So thickness of 120/80 is 96mm.
Thickness of 100/80 is 80mm.

The sensor is in the front tire. If you change the front tire which has significant difference in lateral height, readings will be far from true.

Changing the back tire (with smaller lateral height tire) will change the speed/rpm in real life as it happens. The engine will really rev more for a certain speed.

can i change my tyres to FZ's both front and back!!!??
what will b the cost and will it change my rpm readings???

Almost every bike has speedo errors so the actual speed must be around 132-135...

**Full Throttle** · 03-19-2009, 12:42 AM

Do you think can it go more then that????????

Well i dont really think that stock P200 can go more faster !! Modded P200 can achieve that speeds (Bigger Jets, Spitfire cables, NGK Spark Plugs, K&N Filters etc

)
