Also one can simply remove grab rails, mirrors, cat converter, indicators, number plate, and the rear set pegs.

On the personal front, one can remove T - shirt (50g savings), and jeans(500g). A simple lungi/dhoti would not only help you win swadeshi points but also save on weight.

If the above doesn't satisfy, you can consider removing some unwanted body parts like one kidney(100g) and since the liver is a regenerating organ, you can consider donating a piece before you do a track day. Just 500g makes a huge difference to your timings.

LMAO!!!! THIS Shit just got me cracked up.... [MENTION=58594]leech[/MENTION] , you surely know when to smack 'em down. Epic post brother. Just EPIC!!! 😂😂😂😂

because in traffic engine temperature goes high and engine drain all the coolant.

In this case, you need to check the coolant level and see the coolant level in the reservoir and radiator. A good option would be to flush the existing coolant and refill with fresh coolant. Even with the new coolant, if the temperature indicator goes high, then take the vehicle to service station and get it checked.

when first time coolant was drain it self from engine. so i have clean the radiator and reservoir with new coolant and filled it according to service manual. also take vehicle to the service station that time fan was working that's why service and able to find out problem but today this will happen again

Adjustable levers for Honda CBR250R

*If I've committed some grievous sin posting this here, my apologies to the admins. I couldn't find an answer perusing the forums*

I'm buying a used CBR250 in a couple of days and have a handful of small mods I want to do.

First on the list are adjustable levers.

Anyone know where I can some decent levers for the CBR? ASV's cost far too much

Cheers

Coolant doesnt drain out. Even in traffic did the bar reached H or it didnt come down back to 3bars post riding?

If you suspect the fan, get it checked. Once the coolant on my bike drained too because the fan wasn't working and i was in bumper to bumper traffic. Temperature bar was full. Looked like the second fuel gauge :3

it's draining from coolant drain hose first i think that its engine oil was leaking . only in traffic temperate reached H and it come down back to 3 bars normal riding

Maybe the problem lies with the relay, I'm not sure. But do get it checked

The relay on mine was faulty. And thus, the fan didn't switch on which led to the coolant getting backed from the radiator and the reserve.
Went to the service center and got the relay replaced

It is 2.5 according to the Japanese manual. Theoretically, it can be plus or minus a few 100 ML.

Just for a check, once I rode it till the fuel tank emptied. From the point when last bar starts blinking I managed to rode it for 100km. I was riding at 40-60kmph in mountains.

Mostly I fill fuel when last bar starts blinking and it gets 9.5L to fill it till the neck. I guess 300ml more could go if some time is given to settle down the fuel. So as per this calculation, I would say it is close to 3.2L

Yes, even I rode almost 80kms on last bar blinking prior filling it up. In last 4 years I didn't have a signal ignition failure apart from some rare flooding. But this time with blinking last bar, the bike is not starting at all. Battery is fine as I checked the headlights and those are working perfectly fine.

Yep, I've ridden on last bar blinking for 70-80 kms. No way it's possible with just 2.5L in single bar mode. Also filling soon after last bar arrives, I can put in only 10,10.5L max.

So I assume the online manual is wrong, or else the 'reserve' is set to 3.5L in the Indian CBR, and 2.5L in the jap one

One can run an FI motorcycle till the bike comes to a complete halt. I completely second the last mile calculations by you guys when the last bar is blinking. But mind you, the fuel pump is required to be submerged in the fuel itself for it to run effectively and in some cases prevent air in the lines too. When having a habit of running the motorcycle dry to dry in an FI engine, the fuel pump weakens over time and can fail prematurely. This is why even though an FI engine stops running out of fuel, and when one inspects the tank, you can see some amount of fuel that's left in the tank it's to safeguard the fuel pump from going excessively dry and cause an air lock or failed fuel pump motor.

A few days back I faced this unusual issue of radiator fan running even after ignition key and engine kill switch was turned off. I was cruising on highway at 80kmph in 6th gear(fan shouldn't be running in this condition). As I stopped by a fuel station I observed that fan was running. I turned ignition key off and it was still running. I waited for 5 minutes but it kept running. Later when I reached my place, I took out the fan relay fuse(10A fuse in fuse box) to turn the fan off.

Any leads in explaining the possible cause and solution is welcome.

The fuel pump and fan relay are right next to each other. And what you've faced is a classic malfunction of the relay, and as you've rightly pointed out. A stuck or open relay means the circuit is closed and the power runs to the fan irrespective of what the temp sensor sends to the ECU. Usually old mechanic style of erring/checking out a stuck or faulty relay is to slightly tap with your finger around the bottom and sides of the relay, twice to thrice, once in the circuit and outside the circuit, this has worked many times on different relays and have worked with no problems since then. But, relay costing close to 250 to 300 I'd definitely suggest you change the relay for peace of mind.

Does a worn out ball bearing set really affect handling? Took my bike to the svc , found I have a bent fork, handle bar , t stem, bent top plate, a leak in the front rim, I guess I got used to the handling but lately it's become worse , will be leaving at the svc on Monday to sort out n see what's the issue, was quoted around 3500 , with fork bent removal and cone set change , if top plate n handle bar need to be changed I expect a 8-10k bill.

A worn out bearing can cause uneven tire wear, they can compromise handling, they can induce wobbles at around 55-60 kmph. Now, with so many bent items it's surprising to me to know that you've been accustomed to the handling. (pun intended). Forks can be de-bent depending on the intensity of the bend, and coneset will cost somewhere close to 1500. T stem, upper plate and clipons will be costly.

Anyone could put any lights on this? Was expecting some comments on this from senior and old members but probably they missed the post. Just curious to know what could be the problem that I had to open the trottle and hold the self for about 30 seconds to start the bike. Even I had a quick chat over the phone with CBR mechanic and he told to check the battery, but I'm quite sure that it's not a battery problem as I was able to turn on all headlights without any fuss while the engine was not cranking at all.

Just like any carburetted engine, the FI system can sometimes be erroneous in feeding more fuel than necessary to the engine causing flooding. Think of this as excess choke. The way the injectors are fed is by reading is by checking the coolant temperature and o2 sensor and then the ECU regulates the fuel flow. Sensors being sensors do have dead time or a heat value at which they optimally operate so that's why sometimes they just start well and then stall. That's why opening the throttle WOT on a FI stops the fuel injection and the cranking of the engine disperses all the fuel vapors inside the cylinder when held WOT for 5 to 10 seconds. When you close the throttle to normal, the FI clears its throat and starts injecting fuel and the bike cranks.

I think I've posted this earlier too for a similar query, but here it is again.

ABS NISSIN PAD PART NUMBER

REAR: 06435KYJ901

Also is it normal for the CBR idle RPM to rise to 1.8k-2k rpm in each crank. Even when the temperature bar showing 3 bars?

1.8 to 2k mark on cold conditions is normal, and sometimes the ECU adjusts the RPM up and down which is normal, irrespective of temperature. If you feel the idle is constantly near 2k then we have trouble.

Hello, Josh. Don't you worry, you've come to the right spot. You can start off with levers from eBay, these are decent, though cheapo MOXI, ZOCC branded levers, though I don't recommend one. You can also check aliexpress as they have assortments of accessories for CBR and they do ship it to India too.

Cheers!
