. You have to put camera in macro-mode to allow it to focus on such small items placed too close to the lens , atleast that's how it is on my coolpix 3100 . Also a steady camera support is useful .
Not all camera have this function. I've cheap coolpix L23 cam and it doesn't have this function. Nor i love this cam. I use micro lens on my Nikon D7000.

@ sibun - what ?! they changed the plug to higher heat-range !? previously only Pleasure scooter was using the cr6-hsa . Splendors , Passion & CD were using cr7-hsa .
Sibun suggested and i'm too using it. I've driven in highway too and there is no problem. It is not necessary to use recommended heat range. You can alter with that if u need. My city is very small and i got everything within 5-6 km. As soon bike reaches to its operating temp i reach home. So why not to use one step more heat range so that bike reaches to its OP Temp more sooner. and will have less unburnt fuel and less carbon deposit. You too should use it too. No problem.

Re: Hero Moto Splendor/Joy/CD-Dawn/Passion

Tried macro mode in camera , somewhat better focus in near lens object ,Better than before i think

the entire white part under firing tip is black covered and takes lot of sanding and scratching to remove the black color , Still it stays black .

Re: Hero Moto Splendor/Joy/CD-Dawn/Passion

I think the engine is loosing compression through the valves. It could be that the engine was previously running on a rich mixture and now the dislodged carbon is not allowing a proper seal .

Try to decrease the engine RPM and see how it idles, a splendor with a healthy engine can easily idle at 900 RPM.

Let us wait for sibun as he is Doctor Engineer Saab.

Re: Hero Moto Splendor/Joy/CD-Dawn/Passion

Tried decreasing idle , it dies out , possibly indicating valve leakage . Tried to tune carb yesterday without cleaning it just for a trial , how does one get rpm reading on a splendor ? I puzzled due to this.

Any idea about your fuel mileage ? How long does it take for oil level to decrease on the dipstick reading after a fill or top-up ?
You need a hand-held rpm meter to know the engine rpm in these bikes , all Hero authorised service centers have it and shall usually do a carb-tune for you free . Carb cleaning / overhaul is however not for free .

55-60kmpl , my clutch plates are gone too which is leading to no more wheelies and lack of torque . There is 100 to 150ml loss but it varies . Sometime there is very less oil consumption say 50ml or so .

What sibun said is correct. That was it i was going to point out later. Your mileage is less because of rich mixture.
Your oil is burning through the way coming from valves due to damage valve oil seal. I guess your compression is good.
Now i would say first get those work done before u next open the spark plug again for inspection.
If there would be a delay. Atleast clean your air filter & carb first if needed and tune it to atleast prevent it from excess fuel burning.

Fuel mileage seems ok , but how are you measuring oil loss volume in ml with dipstick ?

Re: Hero Moto Splendor/Joy/CD-Dawn/Passion

[MENTION=29030]Pinaki[/MENTION] da ,last time i changed oil i filled the drained oil in bottle (oem) and saw the loss . As i said it always varies due to my jugaad techniques . [MENTION=6724]Paul[/MENTION] should i go to svc and get head opened and get it cleand , perhaps change the oil seals ? . Cleaned oil filter and under engine area , also under engine area was bit black grimed , suggesting there was some kind of oil leakage from drain bolt too. Loads of work to be done .

Can't tell from which area your oil may be leaking. Better, before u go for the work make a list of all those works to be done, then proceed. Post the pics or first clean those black grimed area throughly with kero then check it out from where its coming. If u can't figure out then post the pics then we can tell u.
If drain bolt is leaking then first check if the bolt is not slipping. If it slips then you'd better get fix that first. If thread is fine then simply buy a new washer (that is aluminum washer) then apply gasket sealant, first tight with hand completely seated then take a wrench and give a slight tight. Just more or less 1/4 and it would be fine. No oil will leak. If u follow this method oil will never leak, no washer replacement will require and your thread will be forever fine. Don't ever get those tightened by any mechanic.

If u get your head opened by svc or anywhere, your work will not be satisfactory as it should be. They are not gonna clean as you can do yourself. They will not open valves and clean them. If u tell them to change the valve oil seal they will say they are fine. If head is opened it is recommended to polish the valve seat for better sealing. But if they didn't do that you will end up with wasting your money.
This job is very easy to done. You can do it. We are here to help you. Even i scared a lot when i opened mine for the first time. But i done it with the help of these guys here. We will give you our ph number and that will become very easy for u to ask for help anytime.

Re: Hero Moto Splendor/Joy/CD-Dawn/Passion

Oh , I have guessed it right

. That is not the way to monitor oil loss , I mean you can't be draining your oil everytime you want an estimate now ? Neither is it an accurate method . Monitor it with the dipstick , perhaps every weekend if you suspect loss . After riding your bike for the day and turning off the engine , put the bike on mainstand on level ground . Wait for 10 mins , then unscrew the oil cap and wipe it off on a clean cloth . Re-insert the cap straight as far as it would go in without screwing it in at all . Now pull it out and check the mark left by the oil level on the marking ( min - max ) on it's tip . Wipe off again and recheck once for errors . Correct oil level is anywhere between the min-max marks on the stick . If the level is lower ( i.e almost no oil on the dipstick ) , top up the level with some spare oil .

Yes , by all means - keep the engine's exterior clean . That way it cools efficiently and it is easy to visually check for any problems on the motor . Old toothbrush dipped in kerosene , followed by a good soapy water wash does it .

Spark plug heat range doesnt affect engine temperature.. unless, hotter spark plug detonating the AFR.. that would be too hot.

Paul man you really inspire me to do things ,infact i love diy stuff but i cant open up head as i live in rural area and even spares like o-rings are difficult to find . SVC mechanic is friend of dad`s so i will give bike to him and see how he does the work , later on i will buy all the spares and tools and do head cleaning myself. I found VALVOLINE fork oil for front shocks is it good ?? . Since fork reconditioning is easy DIY ( Thanks to you post) i will be doing it myself , Its been raining here from 3 days and couldnt even wash bike

. [MENTION=29030]Pinaki[/MENTION] Da thanks sir from now on i will keep an eye on that oil level

.

Re: Hero Moto Splendor/Joy/CD-Dawn/Passion

Yes , monsoon is set in here also and my bike is also got mud splattered all over now . Love rain riding . No point washing it now untill monsoon is over . However I got a proper raincoat for myself this time for a change , made by K C Pal the famous umbrella makers in kolkata .
Valvoline fork oil is good enough . Wayy better atleast than the ₹20 no-name oil used by all the local mechanics here . Even if you buy them the good fork oils , they go to the nearest shop and exchange it for the cheapest one as soon as you are out of sight

.

I would first suggest you to don't take any decision is hurry. Your bike is not smoking too much so u don't need that work to be done urgently.
Secondly, if it is very difficult to find even a o-ring, then how your mechanic would find it and install the OE one??! If your mechanic can get it then why don't you can get it. And i think you don't like your mechanic to install the same old o-ring with a gasket sealant around and a local head packing, didn't you?
Only very few parts are consumable i.e, head o-ring, head packing, valve oil seal, and top, left & right cover packing. others- valve grinding paste, suction cup. Thats all you need. These things are very common and highly consumable, used every time when the head is opened. And any SVC will definitely stock it.

Don't think buying tools and spares later and doing it. How would u get spares later if u can't get it now, huh?...
Oh come on man now don't let your bike touch by any mechanic. Lets do it! If mechanics are there to do things for ourself then why we are here up to?!! Then what would be our purpose here.
You don't need to much tools even, we are up here to tell you everything in detail. The tools all you need the parts you need.
You won't need to worry about anything. I know how you feel when you go for doing something new that you haven't ever done before. but u don't worry.
Only passionate man can do this, and i know you are passionate because you love diy stuff.

For fork - I can't comment on valvoline because i haven't tested it. I used veedol and its good no doubt. Motul is also good. Valvoline should also be good, its a good company. If u have bought it, use it no problem.

You know what? Head DIY is easier than fork DIY
