Hi Guys,

Am facing few issues in m bike:-

Idling issues - The bike's idling is very unstable. I set it up to 1500 RPM while leaving for office and when I reach office it turns to be 3500 or 4500, and when I reduce it, the next morning it is below 1000

Also, if I rev it up to 4000 RPM or any rage and press the clutch to change gear, the RPM just remains the same and does not come down until release the clutch. Basically, it come down only when there is some load to the engine.

Another Problem - Am not sure if it is the Battery or part that charges the Battery. Once I charge the battery to full, it lasts for around 5 days but the moment the battery is dead my nightmare starts. Bike does not start by kick. After 10-15 kicks suddenly a miracle happens and it starts. Now the problem does not stop here.. even if it starts, I ride it for some 100 metres and the engine shuts down. Even if I press the horn or switch on the lights the engine shuts down. I have to kick back and continue my ride. This is how I am travelling to office from past 2 days

People think the bike will not run without the battery, but which I had given my battery for charge, I rode the bike the whole day without the battery without any issues.
Maybe problem with the battery - but if it was, it wouldn't last for a week after getting it fully charged.
Maybe problem with the wiring - I changed the complete wiring of the bike which was worth 2K.
Maybe problem with the part which charges the battery - A local mechanic said it is working fine (I don't think he is expert enough)

but question is, even if the part which charges the battery is faulty, why isn't the bike running after it is started. I can just ask these questions to the HH service center, but I have experienced they are just there to change parts whenever and wherever possible, whether that part is faulty or not. They have already replaced the complete wiring suspecting fault somewhere in the wires.

This is my first post but am not new here. I have been reading through long time and thought this was the best place where I could get a solution. Mods - Please move this if this is not the right place.

Thanks

For your 1st two problems, ur bike is running lean. Tune your Carb for proper AFR .
There is also a possibility of accelerator cable getting stuck somewhere. Get that checked as well.

check your airscrew. i think its a clean case of air leak.

For your first problem there seem to be a wrong AFR setting , making it very lean or there is air leak in the intake...If you take out the plug and see the center electrode is likely to be white,indicating less fuel and more air...
1. Since it had happened recently suspect air leak due to inlet rubber hose crack or tear...most probably done by rats...or wear and tear if you have an old bike.
2. To check if the Regulator Rectifier that charges your battery is working or not, you need a Voltmeter capable of checking DC voltage upto 20 Volts . Set the range of meter to DC and Volts to 20Volts range .open the right side..ie., kicker side panel and you will see the battery , connect Positive of meter to left(+ve) of battery and negative to chasis, and measure battery voltage..it should be 11.5 to 12.5 volts.if not battery is discharged..Now start the bike and let it idle.Check the battery voltage ..it should be 13 to 14 volts.If it is not, then either the main fuse is blown or RR is defective.

may sound funny... But than too
check ur choke lever...
Sometimes wen the choke is on un necessarily.. Bike goes stupid..anything happens widout any reasons.
I m not an expert but may b dis is the problem...

i recently had the same prob on my bike [RPM not coming down when clutch is engaged and no acceleration] this was due to a air leak from AFR screw into the carb. Start your bike then cover the AFR screw slot with your thumb tightly so that it doesn't suck air inside , you can feel the sucktion when you place your thumb. Try this ones and see if the problem is solved , solution for this is cover the AFR screw slot with tape thoroughly so that there is ro room for leaking . You need to tune the carb after this , i kept my AFR screw between 3-3.5 turns [1 turn=360 deg] after completely tightening it in clockwise .

This is a problem that i was facing for a very long time and no one from HH service center was able to fix the problem. But i guess i have bike running in good now. Few checks us need to do yourself. DIY is the best way.

-Check for the manifold rubbers .i.e. from the air filter to carb and then carb to engine. Incase the manifold is damaged then there would be extra air being sucked into and may cause the problem.
-Check you filter and carb setting. Try to get the carb cleaned at the local service center or the HH service center.
-Check for faulty cables, incase they are old replace them or check if they are jammed in any place.Same for the choke cable also.
-Lastly and this was what worked for me. Get hold of a spare carb from a friend's bike and fit it on your bike and see if this works. This is slight expensive if you have to change the carb and thats why i suggest you do this last.

Regarding the electrical issue: what battery are you using, have you replaced the battery, CDI unit or rectifier recently?

Great response and thank you very much all.

Thanks
If the accelerator cable was stuck, the RPM would not come down when I rev in neutral right?

Am a Noob, can I do this myself? or ask the guys in SS to do it?

That's true, creamish.

It's not the choke.

Can you show me a picture of the AFR screw? Am sorry am not aware if I can reach it.

That is too technical for me, I don't think I will be able to to that.

Added it to my checklist in the Service centre visit.

Cables are checked and all working fine as per the mechanic (am not sure if he really checked it).

So if there is a problem with the carb, I have to replace it? No repair chances?

It's a stock battery and did not change anything recently. Question is, even if the rectifier is kaput how long does a normal battery run? Mine runs for approx 5 days without using headlight and horn, which gives me an impression it still has life. My daily usage is around 20KMS.


Tomorrow I am taking the bike to the HH service center guys. I will make a list of things you guys have asked me to check. If problem still doesn't gets resolved I don't know what to do. These service center guys are too lazy to do all these stuffs and not at all trustworthy.

if it is a stock battery,and has completed 2 or more years, then it is time for you to change to a new one, go to a battery shop, ask them to look for electrolyte level and try riding your bike for more than twenty kms without much load(horn headlight). if it is the same, then change your battery to a new one.
