Not using the correct heat range of sparkplugs can cause severe improper combustion. The heat range of the spark plug is specified on the basis of its operating temperature, using an incorrect heat range can even cause the spark plug to disintegrate in the combustion chamber.

Btw, you need to use a combi of 9 & 8 or 9 & 7. I've been using 9 & 7 for the past 46K kms as the SVC centre recommended that its the correct heat range for proper arcing. That being said, people are running with the 9 & 8 and even 9 & 9 combination without a hitch.

I know u both are jealous.

The manual has stated thrice that 330ml has to be filled. Iam running on around 350ml without any problems although there is imbalance in the fork oil level. Give it a try. Try filling 330ml next time. I want to know what if i go more stiffer than this? Advantages and disadvantages. I can do anything to improve the crappy handling.

Screwed tuning.
1. Rich mixture causes low mileage. Lean mixture increases mileage.
2. Thats weird. Any other sounds? Are u sure its knocking?
3. Was your carburetor or jets fiddled before?
4. Once again adjust the idling. Make it 1400 when cold.

Its a sealant used to paste things. Pbk guys will put it.

Good to hear that Bangalore has a working CO machine. Here it isnt working for over 3-4 months. My bike is struggling like anything. Running quite lean now. Everytime iam using Diagnostic tool to adjust CO. It reads around -13.25 now.

But the specified heat range depends on the conditions of riding isnt it? Manufacturer suggests plugs depending on ideal or most likely riding conditions. It can be general commuting and occasional short high speed bursts. But what about when the bike is on the redline always? In this case they may not do the job. The hotter plug will be good for cold starts. Correct me if iam wrong. When the most of the riding is under extreme conditions and the engine is under very high stress and is very hot always, then how will the hot plug be efficient? I mean it can either disintegrate in the chamber or cause pre-ignition (It can become a source of hot spot). In this case having both colder plugs would be advisable. Any comments on this?


What should be the NitroX gas pressure in rear shocks? I plan to keep it at 110psi. Manual says 7.0+0.5 Kg/cm2 which is around 107psi. Will an extremely stiff suspension wear out soon?

Reply in dtsi thread as it was for dtsi.

i got my cut off on 99-100 on 5th gear..

I've got the same problem..the sound comes from about 6-7 rpm and upwards.After a 2-3 trips to the pbk.. Srikanth finally found out that the tappet is making the noise.He did some adjustment and told me to drive for about 500+kms and that was a month ago.Now the sound still exists(900+kms done after i showed it to him)
I'm leaving to pbk in sometime to rectify it once and for all.

srikanth is on leave. he'll be back only on monday or tuesday. I'll be leaving my bike for service on tuesday!

yeah i got to know after i went there.. he went to pune it seems.Even balaji is in banglore...but anyways i got some minor adjustments done today with the help of Mr Fransis.

whuz mr.freansis in hyd pbk???

He is the service engineer for tadbund pbk.

Plz suggest me a new front tyre guys.

You can go for R15's tyre for better handling

hey go for the new p220 IRC tyre 90/90 17.

My 220 DTSi came shod with the IRC's (selected over MRF) and the grip while cornering and in wet is very good. The
One problem is that the IRC's struggle to death if they are taken over even a little slush. I have had a exp in that condition and it scared me to death. Maybe its the tread pattern or whatever.

The tyres are really good but being soft compound life may not be much+am sure puncture problem will be there

I do have loose tappets. But this sound is different. Its typical jingling sound. chan-chan
Even i have many things to get done. Once exams are over i would go.

FZ-16's 100/80


My IRC rear tyre, the same which comes on p220 dtsi's has already started to show signs of wear. Its been hardly 3k kms with that. And this time iam riding very sanely. Iam sure it would hardly last 8k kms for me. If i drive in my style maybe 5k kms.
Since it is soft compound it hardly provides any grip while off-roading.

You scared me huh.
Do you do a lot of burnouts? 3k kms and showing signs of wear, thats too much i think.
What style you ride? Cornering, burnouts. Hope i dont have to buy a new tyre 8 months down the line with 8k KMS on the odo.
Life of IRC is really very less, i dont know a thing about bike tyres but do they all have a similar life?
I thought they will easily do 10-15k kms since our Scorpio has done 48k kms and tyres still can go another 10-15k, seems a wrong correlation
