R15's Coolant temperature sensor failed for 4th time

http://www.xbhp.com/talkies/help-me/20738-r15s-coolant-temperature-sensor-failed-4th-time.html#post733663

I have 2009 (20P) R15, with 21.5K Kms on Odo. For last 1 year, the Coolant temperature sensor has gone kaput on 4 occasions. It first started after a Free Servicing (Yamaha free servicing camp). Later it showed in normal city riding. Third time it happened just after 600 kms from last occasion. On all these three occasions the Coolant temperature sensor was changed after diagnosing Thermosensor failure.
After the third occasion, I got radiator setup, fan and relays checked. Infact, replaced the fan and relays. I have always ensured that the coolant level is upto the mark and I use Motocool coolant and Motul FS 15W50 engine oil (top up whenever required till 2.5k-3K kms). After 3rd occasion, I got my bike Joeled(big bore + Camshaft + FFE + Simota air filter+ head work+ Clutch springs and valve springs) and changed the CO2 level to 5. Since than the setup ran fine. After 4 months (run-in, extended run-in and normal run for around 3.5 kms post modifications) I tested my bike for 2 hours non stop ride and the engine warning light never popped up.
However, on last Thursday the warning light popped again, after 2.5 hours of run, with one break in between. Checked with FID for the error code and it (error code 21) pointed to coolant temperature sensor.
I want to put an end to the root cause. Need pointers to get this problem rectified. I am assuming wiring harness could be a possible culprit, which can cause short circuit. Apart from that I can't think of anything else.
Experts please help.

PS: I have no electrical modifications on my bike. I am not running HIDs or anything that can drain the battery and cause the engine warning light to pop. On every occasion I checked with FID and found that Coolant temperature sensor was malfunctioning and got it replaced

guys would removing the catcon on a stock r15 make any difference to the performance and efficiency of the bike??
also if possible can someone post a DIY of how to remove the catcon or a picture of where the catcon is exactly located on the exhaust??

I am facing an issue with Orange warning light.Warning light with error code 15(FID tool suggested Throttle position sensor) is popping up when I start the bike. Initial inspection at SVC by lead mech. suggested clogged protruded part of Throttle Position sensor in throttle body. As such, the throttle body was taken out and cleaned with petrol. However, even after cleaning the throttle body thoroughly, the error is still popping up. The Lead mech. says I ll ve to change entire throttle body as the Throttle position sensor cannot be changed individually. My bike is more than 2 years old and no more under warranty. Is there any solution other than changing the entire throttle body(can throttle position sensor be changed individually).

Can someone answer my questions regarding battery switch:
- How safe is it to use high rated battery ?
- Using the 5Amps battery will raise any electrical issues ?
- Any precautions/warnings/care should be taken before going for 5Amps battery ?
- Can you specify some advantages of replacing the stock with a 5amps battery ?
- Can I go for a higher wattage bulb if I switch to 5amps battery ?

Dude i doubt your censor is out of life, or there is some wiring mismatch. Is the radiator kicking properly ?

@chiyaanvhinnu - I think amaron has a 9amps battery which one can use on R15 and i think the sheet below the battery has to be removed for the same, And the electricals and charging unit will easily take care of the charging.

Currently my bike R15(Joeled) has Motocool coolant and I am observing a weird behavior. After flushing the coolant in last servicing we filled Motocool in reservoir and radiator and left SVC( servicing done on 22nd June). After one week I noticed the coolant level at the middle of reservoir(after around 160 Kms post run-in). I presume that we didn't top up after filling the reservoir and radiator and starting the engine. Topped up coolant on 30th of May till max level and continued. Today after a short ride, I noticed the level of coolant has again gone to mid level in reservoir and till now 320 Kms have been covered post servicing. I am not sure whether this behavior is normal. In this 320 Kms post run-in the fan kicked in only once and I assume coolant circulation is normal. I have a few concerns-
1) Is the head gasket not filed properly. Normally if the gasket's diameter doesn't match the 165 cc diameter, entire coolant would leak within a day or two. Also, I never noticed water or water vapors in exhaust,
2) If gasket is okay, is the coolant leaking. Since, we opened radiator , reservoir and refilled coolant , there's a chance of loose connection.
Is this behavior normal?

Yamaha R15 good mechanic required in Chennai

Hello everyone, This is surendar from chennai. I own R15 which is 2 1/2 years old. I have been servicing my bike in regular intervals at RAJ YAMAHA. I am not quite satisfied with the service, the reported problems are not addressed properly, since they have huge base of customers, and always the service center is full. I have raised the issue with service center owner but in vain. If there is issue with some part of the bike, 80% they replace the spare part with new one without informing the owner, and without even attempting to repair it, last time I never reported any problem with rear disc pad, but when I went to take the delivery of the bike, the bill was showing disc pad billed in it, the service center representative was giving lame excuse that break pad is weak, and he showed me one worn out pad, I am damn sure it is not the disc pad from my bike. And, recently I had changed the chain sprocket kit, and the chain was not fixed properly, every time I put 1st gear, there is a knocking sound from chain.
Please help me with some genuine mechanics for R15 in chennai, I would prefer giving it to them rather than getting fooled by these so called authorised service center.

Thanks, Surendar
