Re: Overhaul

The bike Drained at 500km after the overhaul, could not check more thoroughly but as it seems the guys over the Mechanic shop used 10w30 honda oem oil and put 1 littler whole bottle ://
when i return home at evening and heard the matter, immediately checked the oil level it was a inch over upper level, siphoned out 200 ml still its over the upper level.
Summer was incoming and 10w30 is not recommended grade for this old engine right !!! and about the oil volume....





Is it 700 ml after draining and 20W40 ?

Re: Overhaul

Yes , I am aware of the spanner method of seating valve springs on other bikes , but it needs some help and is fiddly . Usually I have to work alone and so I have to consider methods that I can manage all by myself . You mean 8/9 ring or 10/11 ring ? I have the following in this ranges - a cheap slippery 10/11 open , 10/12 open from bike's OE tools , 8/9 open , 10/11 angled-ring and a 10/10 combination . What's the exact size of that nut ?

At the cost of boring everyone with repeating this for the tenth time -

Volume ( milliliter liter etc ) have no relation to your bike's engine oil . Only thing you have to ensure is the oil level stays between the upper (max) and lower (min) marks on the dipstick at all times . Higher or lower oil level is equally bad for the engine .
Also - read the owner's manual carefully and follow the given procedure exactly to check this oil level - so that there may be no chance of mistakes in reading the level . Because there are several ways you can make a wrong oil level reading with the dipstick . (if you ask I can explain this procedure) .

20w40 is great for Splendor in summers , for a new/ newly bored engine hero-10w30 would be good until the gaps run down a bit .

Thank You

Yes if you please. BTW that illustration from the workshop manual for original cd100/sleek...

Re: Overhaul

Place bike on main-stand on level ground for about 10 minutes after a ride . Clean off loose dirt around the dipstick hole so that none may fall inside when open . Unscrew the dipstick and wipe it off with clean dry cloth . Re-insert the dipstick into the oil-sump hole straight , vertical & not touching the bike - until it comes to rest on the threads ( don't screw it in at all ), leave it there and remove your hand. Now withdraw the dipstick and check the portion at it's end wet with oil . That shall be your oil level and it should be between the max and the min marks on the stick . Pour in a little fresh oil to top-up if low . Twice again , wipe off the the dipstick and check to confirm . Check oil level once a fortnight , at least .

Re: Overhaul

Hunk's manual recommends idling the engine for around 3 mins before checking the oil level. What could be the reason for that?

Re: Overhaul

Xtreme's manual also says that. Also it is not mentioned to wait for 10 mins on the manual. idle for 3 min shut off engine measure oil level using dip stick, that what manual says

Re: Overhaul

Maybe so that the oil is at normal operating temperature.
But without giving some time (I prefer 30 min on main stand), we may get lower oil reading because the oil would still be trapped in the crevices and stuff!

Re: Overhaul

Yes , even the Splendor's manual says "start the engine and let it idle for 3-5 minutes ... " . Then remove dipstick and measure level . There is no confusion in this . This is because the owner's manual recommends the oil-level check as part of pre-ride inspection checklist , i.e things to check everytime before you ride . It is meant for a cold engine that has been resting for the night . 3-5 minutes of idling shall circulate the oil in the engine same as about 10-15 minutes after a ride and a well warmed engine . In both cases , oil level readings shall usually be the same , and I have checked this . Obviously like everyone else , I don't check oil-level or the whole of that checklist before every ride ! I seldom have time to do all that when going out , so I measure by the method I said - since the results are identical , and can be applied anytime even during a long ride .

Divya_Sharan'jee , I feel you should reduce the wait time to around 10-15 minutes . This is because correct oil-level is not when ALL the oil is back in the sump . It is when most of it is drained back into sump while all engine internal parts are still coated in oil . i.e it is a measure of circulated oil , and should exclude the coating oil . If you get what I am saying

Motorcycle engines are not designed to drain all the oil back into the sump . It has traps that retain oil in the vital lubrication areas ( like the main bearings ) , for the next cold start . If parts like the main bearings are absolutely dry on starting , it may grind to an early death . It is because of this designed oil-retention , engine-flushing is not recommended for motorcycles .

Re: Overhaul

A small correction Pinaki ji, cars don't prime the oil pressure before starting. The oil pump in most cars is driven either by the timing belt/chain or by the crank directly.
You must have got it confused with the fuel pump which pressurizes the injector's fuel rail.

It takes less than 2-3 secs for the engine oil to reach the top most part of the head.

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

Here's something that Our Sibun Ji was searching for a long time for his Joy.
Glad to help that person.
I sourced him the Sticker Set from the Pudupet, India's, Oops, South Asia's Detroit!!!
Going to send the stickers to him by courier.
But he says that he has some more and some other plans. He said me to send some more spares or else he will come to Chennai and collect the pars personally. He is confused between both plans I think.

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

So tried out the Italian job on my Splendor!
Redlined In 1st gear for about 25 seconds.
Yes of course, the engine screamed like hell and I had the fear of engine getting seized. Because bike ran 1.5 lax kms + so that had that fear.
And forgot to mention that I put a small hole on 1st core. Now the bike is free revving after doing both Italian and exhaust job.
Silencer sounds like an Enfield Bullet esp. In the rev range of 2750-3500 rpm. Sibun ji told that is the rev range where CDI fires for the longest time.

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

Can I fit any 2-stroke engine on my Splendor?
See below User ID, Its written '2-Stroke Lover'!
I mean '2-strokes' like Shogun's one / RX's one / KB's one.
I know and I am sure that I need to weld and modify the joints to accomodate.
And another issue, Splendors engine is leaned forward about 75 to 80 degrees but none of the 2-strokes are leaned forward.
Can the frame take that horizontal engine?
And, for now, I am going to fit a Super Splendor Bore Piston kit with the existing head.
Can I fit the Super Splendor bore with the existing head of 100cc bore kit?

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

Instead why not source a 2 stroke bike
And keep it along with your existing bike
You'll more happy having 2 classic bikes in stable

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

I am already having 2 bikes, 2 scooters.
I live in a apartments for rent and the management is always shouting at me for having 4 vehicles.
That's why asking this!

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

If you bore up, then the head would be restrictive as the ports were originally designed for 100cc, plus you would need to change the fueling as well.
