Good evening all,

Referring the above problem of MIL on, took her to service centre yesterday. The service centre guys took a ride on the bike and said one of the black just below the seat is loss and said he has tighten the wires again.

Came back again happily riding and faced no problem till again the same problem started with MIL on and poor throttle response. Night was there so couldn't check the same.

Today in morning the first thing I did was to check the wires again. Removed the small connector between the wires and blew wind so that any dirt near by or into comes out. Went for a ride on the bike again and the same problem cropped up. Now really worried about the bike. Don't want to ruin the vehicle by unnecessary accelerating it. But work is there so have take the bike.

Experts please if any comments will be more than helpful.

Btw removed the rear seat and well it feels like a new bike altogether. Just a small scratch on the rear mud guard. Hope to clean it via washing and waxing.

In the Service Manual it lists three faults that will cause the MIL to stay on while the engine will still run but with less power.

These three things are:
Throttle Position Sensor (TPS) circuit malfunction
Manifold Absolute Pressure (MAP) circuit malfunction
Engine Oil Temperature (TE) circuit malfunction

About all a person without the proper test equipment can do is to check the electrical connection at each sensors location to make certain it is plugged in properly.

The MAP and TPS sensors are located on the fuel injector behind the cylinder head.
The TE sensor is located on the rear of the right side of the cylinder just under the fuel injector.

If careful removal and then reinstallation of the wiring connectors to these things doesn't fix the problem there is a good possibility the sensor is faulty and needs to be replaced.

Your authorized RE dealer should have the test equipment to attach to the computer to obtain the fault code. Once the fault code is known it should be an easy matter for him to correct the problem.

If your authorized dealer doesn't have the equipment to find the fault code about the only option is to find one that does.

As for riding the motorcycle while the MIL is lit, the reason there is a lack of power is because whenever one of the above problems is found by the bikes computer, it switches to a pre-programmed "fail safe" or "Emergency backup" program that will allow the engine to run.
When it is in this mode the computer doesn't know exactly what the advance/retard or fuel mixture should be so it provides a safe setting for both of these.
This allows the engine to run without harming it but it won't produce the normal amount of power.

Said another way, with the MIL illuminated you can ride the motorcycle without harming it but it will get very poor fuel economy and very low power.

Find a dealer who can actually identify and fix the problem.

Seat Modifications Help!

Did a 370 kms weekend roadtrip on my C500, man the butt hurts real bad!!! Anybody here in Bangalore can please help advice seat modifications for both the rider and pillion, would be of great help.

My pillion was my wife and that too the first time, believe me butt-breaks extended the one way ride by about 1.5 hours more than the actual ride. I'm still married and no she's not decided to dis-own me yet. So even before she could I've promised her to get the seats replaced before our next ride, hence requesting your advice!

Last Sunday while riding in Kamanahalli area, I noticed a MAROON RE Classic (not sure if it was 350 or 500), but the seats were indeed modified and looked much more comfortable than the stock ones. If you are indeed on Team BHP, or if you happen to know this person, please help with some advise on where in Bangalore I can get this done.

Thanks,

Unable to go beyond 110kmph

One other thing that I missed asking earlier, through the trip I could not manage to go beyond 110 kmph even on the empty stretch of the NICE Road. The moment I cross 90~95 kmph, there is a lot of vibration! Should I be worried about this? Should I take it back to the RE Service Center and complain about this?

I did mention about this during my third service which was done about a week ago, but somehow only the pickup seems to have improved post that, but was not able to go past the 110 kmph mark.

There are so many on the forum claiming top speeds of 140 kmph, seems like I'm really missing something big or my bike needs some serious attention! What could be the problem, please help!

Contact Junaid/babloo at "art of motorcycles", close to dairy circle in Bangalore. Their no is 9741666669.
Take your bike there. Ask them to install 'PERFECT' seat for both rider and pillion. Also ask them to install Their version of RD handle bar. Ride thew bike with pillion. Pay for the seats and bar, if you like them. Most probably you will like them, as most of their customers have so far. A little expensive it may be.. about 3500 for rider + pillion seat. Give it a shot.

[anandkenkare]

Do you have a picture of the 'perfect' seat ? I am really curious to know more about it.

U can have a look at the PERFECT seat at the following link:

http://www.bcmtouring.com/forum/moto...fi-t17139-513/

The seat on the teal blue C5. Both the rider and the pillion. I guess the owner is put an additional seat cover on the perfect seat, but it should give a fair idea of what the seat is. Its a bucket type.

Here is another example of the seat:

http://www.bcmtouring.com/forum/moto...fi-t17139-516/

is the same RD handlebar you are riding with?

I am riding with the old RD handle bar. Junaid's version comes with a cross member and is powdercoated black. He is also developed a few length and width based variations of the same to suit different style of riding.

Thanks a lot nasirkaka, will go there soon and get the new seats

Can you please help me with the below question as well?

haha.. even i have been looking for those answers. Let me know if you find them.

I have gone a shade over 130kmph a couple of times, when the bike was around 10K kms old. Not at close to 30K Kms on odo, its even difficult to touch 120, even on open stretches of NICE road.

Vibes to an extent can be taken care of by tightening all the nuts and bolts, especially the engine mounting points, footrest connectors, engine to frame connecting rod under the tank, and all other joineries including the crash guard mounting. a few weeks back, i did tighten them myself, and found a few bolts on the crash guard to be quite loose. They may not rotate with finger pressure, with a spanner, we can feel the difference.
After tightening all the bolts, it did bring down the vibrations a bit. Immediately nest day, i went for a service and got the engine oil replaced. I also got a new set of clutch plates installed. The old one had done about 30K and was sort of worn out, thanks mostly to Bangalore traffic. The bike feels much calmer, and smoother, thanks to the new oil and the clutch plates. Yet to test it on highway and see if the speed is improved.

I also got a NEW MALAYSIAN MADE SPARK PLUG for the primary. its a 3 electrode spark plug by the name MAGNUM 3X. Costed 150 Rs. Did not find much info on the net, about heat rating etc. Thought to try it anyways. Been 2 weeks and i am pleasantly surprised. The cold starts have improved, and in general the bike feels healthy.

Coming back to your question, is the bike not going beyond 110 at max throttle? or is it that cos of excess vibes, you r not giving throttle beyond 110?

[mobike008]

I have the same issues with top speed. When I am at 80kmph, its fine.

Beyond 80kmph, every km seems tough due to several factors

a) Vibrations
b) Feeling of excessively going fast
c) Not being comfortable beyond 100kmph

I have taken by C-500 to maximum 100kmph and i just couldnt go beyond that till now as at 100kmph it feels just too fast and bike doesnt seem to go beyond that speed.

Besides, i have a new problem now. I changed my exhuast to a local made in Hyderabad and my mileage seems to have dropped to 20kmpl

I checked the following way :-

Last time when i topped up the tank. Filled in 9.75 Litres

Rode for 200kms and topped up and I got 9.65 Litres

To impress the people around, i give more throttle now because of the lovely THUMP after the exhaust change and press the clutch more than necessary during the course of revvin'

Is the FE drop due to above?

Thanks a lot nasirkaka, have been following your posts and patient replies to all queries. Bow down & Hats off to your knowledge on the bike and your passion. Three Cheers Would love to ride with your sometime!

Just a few minutes ago, I dropped into the RE Service Center (Brand Store one) and spoke to Ashwin and Naveen, they suggested I bring the bike back tomorrow and get the nuts and bolts tightened to reduce the vibrations.

Now that you've asked the question, even I'm wondering if it is because of the excess vibes that I was not giving the throttle beyond 110. Just out of curiosity, when you mentioned in your post that you've done 130 kmph sometimes, how did the bike actually feel. Was it cruising with vibes that were acceptable or you just pushed it ignoring the vibes?

Thanks mobike008, I can only empathize with you on the feeling of not being able to do a 120 on the C500! However, you've brought about two more interesting topics.

Changing Exhaust: Having read several posts of nasirkaka even on another forum, I believe it is best to keep the OEM stock exhaust for the better health of the bike and environment. However if the thump really excites then the common suggestions from the GURUS "who've been there n done that" is to max change it to the UpSwept from RE.

Checking mileage: Even I'm kinda confused as to what is the right way to check the mileage. As even I've done a similar process of checking as what you've done and found my mileage to be about 28-29 on an average, but was kinda feeling weird when I shared this FE figure with the RE Service Center Manager. They seem have a funny "are you sure?" kinda look on their face.

If there is a decent proven technique to check the FE of our C5's, please do share the same. Apologizes if thats already been done in previous pages, coz as far as I remember reading, I couldn't seem to find it.

Hi,

I've booked my DS500 a week back and expecting it in the next 10 days Yes you heard me right - no typo there. I'm from Bangalore and the wait period is well over a year. I've booked the bike in Vizag, Andhra. My plan is to ride it all the way back - 1052kms... I hate to transport the bike in cargo, not just for the additional costs but worry about it's handling. This is my first BULL and the thrill to ride it is also responsible for preparing to ride it at speeds <50kmph for the first 500kms. Planning to give my bike on day 2 for it's first service in Guntur or Vijaywada. Looking fwd to all guru's for your piece of advise - as I would like to remind you that this is my first BULL. In the past I'd ridden the Ist gen pulsar and then the Avenger.. I'd done such long rides in the past and they have moved my soul all the time

[the_trooper]

Congrats! Very inspiring to see so much spirit.

Dont spend too much time with keeping speeds low and all, go easy with the throttle and utilise the bikes torque to move ahead...just dont let it stutter around. Running in rpm based, not speed.
Highways are one of the best places to run in a bike. If the weather is hot, take a few breaks to cool the brand new engine.

Otherwise, as long as you dont go WOT in every gear all the way to Bangalore, you ll be absolutely fine.
