it helps a lot vibhanshu ,thanx,shall i drain my oil out n change it to normal

Hello guys,

As I had mentioned earlier, the cone set for my R15 is about to be there at SS by tomorrow. And so I'll b going for the repair work prolly by tomorrow or day after tomorrow.. I have already done 3 services of my bike and the 4th service is due on 2nd May 2009.

I was thinking to get my bike serviced when I go for the repair work instead of waiting till May 2nd.

This is my 4th service guys.. I need a few answers.. Plz co operate..

1) Is there any special care to be taken for this service? My bike is around 6000kms old.

2) I was thinking of going for K&N for my bike. I have heard that there isn't drastic change in performance of the bike, but what ever little boost it gives, I am fine with it. So is it advisable to go for K&N at this stage of my bike's life? Or is there a certain period after which one shud go for such filters?

Is there any particular model number or type of K&N to b used for R15? I have no clue of these filters..

3) I was also thinking to go for Iridium spark plugs. Are they good to go?

4) with above mentioned mods, are performance cables like spit fire and all recommended or without them it's fine?

5) I had also asked you guys bout the fatter tyre modification and I got real good help from you people..Thanx for that. I am still not sure if I'll go for those tyres or not but I'll surely think over it..


Another imp question I have is.. I bought my bike after the last year's monsoon. So I haven't got a chance yet to test my bike's tyres in real wet conditions. So those who have tested your bikes in monsoon, how's the stock tyre performance in wet conditions?

Also, are IRC tyres good in wet conditions? Other than IRC, are there any other good tyres which you can recommend for R15?

Guys please help me with these questions.. Cause I'll b heading to SS soon..most probably tomorrow..


Hydbiker..santoosh..Aparajith..guys..please help... wher r u?

Hey Ketan,

1. Well, make sure that the svc guys complete all steps in the manual. Am sure KP will have better comments

2. NO!!! U will loose any pickup, top-end etc. No boost, nothing. As mentioned earlier, u will lean out the entire mixture. Not at all recommended.

3. Yeah, Iridium plugs are better simply for the longer life they will last

4. Going by people who have tried it, fitting a spitfire directly replacing the original cable is not possible. See if u can do that, else its an obvious waste of money

I have ridden it in very heavy rains. The stock tires are decent. Not bad. But the bike does tend to slide on slush and mud.

That shouldnt be necessary. But even in any case get a replacement of oil in the next service. The semi synth has just some more of viscosity than the mineral ad survives at high temps. But do take care of your bike i.e. do not cross 7.5 RPM. Rather the best RPM to maintain after 1st service is 5-7. The engine opens up with each km and you would feel it.

@Ketan: I've done just 4300Kms but still I'll try to answer you.
Follow the manual.
Its not about the period. Its about the technology. The ECU does not support high performance K&N. There is a thread already for it. You can find full information there. Check back a few pages, I have mentioned it earlier about one guys experience.
1060does matches. Although you will have to cut the stock air filter pipe. But then again.. whats the use!
Yes they are good to go.
With spit fire it works better but its kinda difficult to completely remove the stock cables.
Stock tires are good with wet conditions. If you want more performance they checkout the BridgeStone website. They got good stuff out there. But you'll have to get that imported I guess, please share your experience. I cannot comment about IRC. As per me, I am fully satisfied with the stock tires performance. You can lean as much as you want with confidence.

Hey guys..thanx a lot for the help..
It's much easier now..

Any more suggestions are welcome guys...

Ketan

1) Get the air filter cleaned by blowing air into it (from a distance... else the compressed air can tear the filter paper.

What happened to your cone set problem?

2) 3) & 4) All this depends on how much "paisa" and "khujli" you have.

IMO the best bet is just go for a NGK GPower (Platinum) plug and that's it. K&N is a waste. No performance... if someone swears by it, drag with the bike and also check top speed.. then interchange the riders and check the same thing again. Please let me know the result.

Iridium Plug, I am really not sure how much better it is over the Platinum plug. It should be better but is it worth the buck we pay is a question. Yes, I am running on Iridium, Don't perceive a clear difference except possibly a tiny bit of better acceleration at higher RPM's - which is evident as the regular Nickel plugs do miss a fire frequently at high RPM's. I went in to buy Platinum plug at Rs 120 (MRP Rs 130) but was getting Iridium at Rs 475 (MRP Rs 550) so bought that instead

Spitfire, I have already mentioned many days back that the ignition cable is a sealed type from the HT transformer and the posts here in the last two days confirm a lot abotu that. Just leave that there and forget about it until you have a better way to find out whether just joining the spitfire cables to existing cable does any good or not!

Tyres: They are very good. Yes, would slide in slush (wed slippery mud) but that would be a problem to most tyres. So, slush in slow speeds and gravel/coarse sand in corners, I am not confident... but I am so with any bike... even the tractor (P220 with a Sirac).

But there is a wide variation in terms of topspeed recorded by owners out here.Also the speedo error comes into picture.Would like to know the actual top speed.Has anybody tried to get GPS/Speedgun readings for top speed?

The true top speed of an R15 is 135-138 Kmph .

My friend has recorded 134 as his top speed on his Gps phone while he said speedo showed him around 141

variation in top speed reported by owners is primarily because of varying the conditions they tested it in and weight of the rider... recently when we took out our bikes on to a newly opened 4 lane highway I clocked 137 KMPH. My top speed on the same highway few days earlier was 138 and I could sustain 137 for some good time but this day I struggled to even maintain 135. On this same day another rider in the group did 143 or 144. He was lighter than me by at least 15 KG's.

and yeah... another day we checked with phone based GPS systems... 134 on Speedo gave us 125 on GPS. But the same thing reported over 250 KMPH as top speed in the next run on a P220

hydbiker , better not say much on top speed cos u ll have someone barge in and say its impossible..
with a video proof too :-D

u have ur answers

Hello Ketan,
1) Is there any special care to be taken for this service? My bike is around 6000kms old.
Nothing spl, just normal. Chk coolant level

2) I was thinking of going for K&N for my bike. I have heard that there isn't drastic change in performance of the bike, but what ever little boost it gives, I am fine with it. So is it advisable to go for K&N at this stage of my bike's life? Or is there a certain period after which one shud go for such filters?
not my cup of tea. its all BS
Is there any particular model number or type of K&N to b used for R15? I have no clue of these filters..

3) I was also thinking to go for Iridium spark plugs. Are they good to go?
They are good , they are self cleaning and thats the oly benifit you get.No other differentiable gain.I would stick of platinum or stock and clean them once a month. Iv used iridium for long enough , three sets cos i got them free of cost, nothing really mind blowing.

4) with above mentioned mods, are performance cables like spit fire and all recommended or without them it's fine?
The r15 stock cable is good enough.
Rich boy's accessory i must say.
If ur bike rev's to super hi range and there is a loss in current , then u may need , else NO.
For the ppl who say feel the difference , i dont agree.
Dyno it to know the actual difference. few % , 1-5% oly.

5) I had also asked you guys bout the fatter tyre modification and I got real good help from you people..Thanx for that. I am still not sure if I'll go for those tyres or not but I'll surely think over it..
Stick to stock tyres, else they ll simply hamper ur dynamics , more than the thin tyre , its the curvature of the 100/80 thats helping the bike. My two cents , Stick with it.

Another imp question I have is.. I bought my bike after the last year's monsoon. So I haven't got a chance yet to test my bike's tyres in real wet conditions. So those who have tested your bikes in monsoon, how's the stock tyre performance in wet conditions?
Very Good in rain have done three figures comfortably with confidence, bad in slush .even 20-30kmph in slush is scary.

Also, are IRC tyres good in wet conditions? Other than IRC, are there any other good tyres which you can recommend for R15?
This tyre Sticks to the road like crazy, so u better stick with it. :-D

^Good one santa...lols !

Depends on the way you drive. If you're a ripper like me, you'd like to check the sparkplug for any skipping fires(the mechs know how to do it),check quality of coolant for any deterioration,you might want to change over to synthetic oil ASAP,tightening of all the nuts and bolts that connect to the frame directly(including the engine manifold nuts),etc in addition to what the manual says. And btw, if your plug is a Denso one, please don't compromise and listen to the mechs if they say "sparkplug achha hi hai"..make the judgement yourself based on the sparking you see.

If you're a gentle rider like Sarvajit, there's nothing much for you to do..general servicing and oil change with a top-up of brakefluids/coolant fluid if necessary along with all the points that everyone else above have said.

2) I was thinking of going for K&N for my bike. I have heard that there isn't drastic change in performance of the bike, but what ever little boost it gives, I am fine with it. So is it advisable to go for K&N at this stage of my bike's life? Or is there a certain period after which one shud go for such filters?

Is there any particular model number or type of K&N to b used for R15? I have no clue of these filters..

KnNs are a NO for now. Atleast until we get the TBR juiceboxes or FIDs.

3) I was also thinking to go for Iridium spark plugs. Are they good to go?

A lot better I'd say..if taking the engine's long term life into consideration. It maintains the cylinder/piston clean because of lesser unburnt fuel deposits. The advantage of an Iridium plug is not cos of the material, but it is cos of the thinner electrodes it offers. The thinner the electrodes are, the better and brighter and powerful is your spark that comes, even with lesser voltage availability(and this lessening of the voltage availability happens at higher RPMs, more so cos of our bike's battery and electricals). So, the thinner electrodes try to maintain a good level of current even at such low voltages,thus giving better sparks at those RPMs, thus burning more fuel. Even if all this doesn't give you any power or mileage results,it'll atleast help you maintain the engine clean.

4) with above mentioned mods, are performance cables like spit fire and all recommended or without them it's fine?

Yes, cos the stock cables may hamper the efficiency of the thinner electrodes. Significant levels of the advantage offered by the thin electrodes will be eaten away by a high resistance/fatter cable(which normally comes as stock cables to handle the high voltage and high currents of the fatter electrodes,cost reduction of spares).

And about point number 5, what everyone told is right...stick to the stock like Santa says. The stock tyre is good on water,it's only slush/mud/sand that you should be scared of. You're good as long as your tyres are on the road,doesnt matter even if there's water on the road.

Guys....

I am done with the 4th service of my bike ... 6k on the meter.. to my surprise, the front disc pads and rear pads were worn out.... i am more of a city rider and also not very aggressive on the brakes.... still... i was socked to see the pads being worn out... i asked the mechanic to show me the pads and it was worn out..... spoke to MG yesterday and he told me that the pads should last for 10k to the max.... has anyone else had the same problem... remember reading the thread about this but not sure which page.....

Any advise......

If you had seen the pads being actually worn out than cannot help.But I have been asked by SS to change pads since 6k mark.(i guesss its their standard suggestion to all to earn something more )I finally did at 12k with no issues either with the disc or with the pads.
