1. No - but how do you decide that it needs an adjustment? What are the symptoms? Could it be so that the underlying issue is completely different?
2. Yes! You won't regret it.
3. Yes.. just don't tell Honda ASC to do it and turn your back on the bike in the process. DIY for best results.
4. Quantifying this is would be IMPOSSIBLE! Benefits would be theoretical at best. But there are some bad petrol pumps which you should avoid - some forums have sticky threads to enlist such.
5. Headlamps aren't covered in warranty. Also, when upgrading, you could keep the original stock locked away. Then you can put them back on whenever you need a warranty claim. Circumventing warranty limitations might not be ethical, but then again, their definition of warranty isn't ethical either


20w50 is available in Motul 7100, suits better in Indian conditions.

Can the bike cruise around at 100 without much hassle?

The comfortable speed would be 85-95. Cruising at 100 for extended periods isn't comfortable on this machine.

I am now getting more than 50km/litre mileage after 1st service. Before that it was just 35km/litre..
Engine became so smooth and no more annoying sounds..
I think it's all about the engine oil using..

I always get mileage around 50kmpl... I kept around 60 during run-in period and occasionally went to 70-80km/h.. The issue am facing is the engine heat and I don't know whether its normal, but I could hear tik-tik sound when engine is turned off after riding around 20+ kms... Can anyone confirm this... And am also facing some burning spell from the part of engine too.

Hey Buddy,

First off I do not know the correct answer to your question and in fact I am mulling the exact same question in my mind since I want to do the exact same thing you want to do, viz. upgrade my headlamps from 35/35w to 60/55w. I however am in no mood to carry out any modification like coil rewinding or Ape RR and stuff like that.

As it turns out it is not as simple as it sounds. First off the question of battery only comes if your bike is full DC. My bike on the other hand is half DC half AC. My headlight & tail light run on AC. Turn signals, console, neutral indicator, highbeam flash & brake light run on DC.

So if I plonk in a 60/55w in place of 35/35w nothing is going to happen to battery per se cause my head lights do not run off the battery. But this statement is not completely true, since part of the current generated by the alternator goes to charge the battery (as DC) and some of the current goes to the head light (as AC). So the alternator should not only be able to provide higher wattage to the head light but should also generate enough current to charge the batteries at the same time.

It is only slightly different if your bike is full DC. The only difference being that all current drawn is from the battery and all current generated goes to recharging the battery. Suppose your alternator generates 200watts of power at 5000rpms. Where as at any given time the bike only requires 150W of power to run the electricals (all lights, horns, fuel pumps, starter motor etc.), then that means you have 50watts extra to play around with. So if you change a 35/35 to a 55/60 even then you will have extra current to charge the battery.

Does it work this way? Yes, in fact most Karizma ZMR owners (which comes with a 35/35w stock) simply replace with a 60/55w just like that cause the ZMR alternator produces a load of watts to over compensate.

So the point in question is not whether the battery can take it, the point is whether your bike can recharge the battery as fast as your electricals are draining it. If your bike cannot then no amount ampere hour battery can sustain given enough time. If you bike can then even the smallest 3Ah battery will work just fine on your bike.

I request other members to find loop holes and lacunae in my understanding and fill it with knowledge. Some deeper understanding such as whether heat output of 55w bulbs would affect head light reflectors / or current carrying limit of bike wiring, will it be able to handle a 55w/ or if the bike is half AC/DC (like mine) then can the 55w headlights handle the flickering at low rpms. If people can shed light on these aspects then I will be grateful.

Thanks!

TL;DR - As Hornet has AC wiring we can upgrade 35w headlight to 55/60W.
We have 4Ah battery

Thanks for quoting my old post @anoopkumar0 ! Slight correction in your conclusion though - If hornet has DC wiring then you can upgrade from 35/35w to 55/60w simply by swapping bulbs. Otherwise its not possible and you have to fiddle around with Regulator/Rectifier unit or convert bike from AC/DC to full DC. I don't know when you said "AC wiring" whether that was a typo or you misunderstood my old post. Thanks!

We need to understand. This is just 160cc engine. I had driven RTR180 for couple of min, I don't feel going over 100 much of extended time.
It's because of two reason ,
-Not enough power to cruise at that speed.
-Road conditions even on very good roads.

I have little knowledge, I believe Hornet's headlight also runs on electricity generated by alternator. Our headlight goes dim when accelerator is low.
Which means if we swap out 35w to 55w, it will not effect on battery (Only battery will charge slower as more power goes to headlamp)


Please correct me if I am wrong here.

Well @plasmabhai did try a 55/60W bulb in his Dazzler, and it didn't work well. It glowed dimmer than the stock bulb.
