Do a compression test,it will tell you engine bore condition.for more information check the other posts.page 36 for engine overhauling details by sibun.change start rod oil seal,if oil leakage is from there.better to do at a good mechanic and watch for the first time,then get confidence and do.wait for some banglorians to reply about good mechanic.BTW are you a member in dishtracking form?

[MENTION=29030]Pinaki[/MENTION] sir, where have you gone? It's been way too long since you posted here!

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

Dear all, My friend has a 8 year old Splendour that has done about 1,10,000 on stock bore. From what he tells me only the clutch plates have been changed around 70,000 mark. It's his first bike and he wants to keep it. What would be the minimum amount that he needs to spend on a proper engine job.

Could someone share their experience wrt going for a rebore with Crank rebuild vs replacing with a brand new oem block piston set and new crank.

Thanks for your time.

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

don't worry , I visit as often as I can to read all your posts . nothing interesting to post from my side so am not . but love to read all yours , particularly those with pics of road trips .

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

Better to go for a new borekit will cost 1700/-+/-,reboring will cost you aprox 800-1000. oem crank cost aprox 3500/-. Normal engine work with new borekit,will cost 6000+/-. i.e without new crank.normally no need for new crank,just lathe work is enough.

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

If your friend want trouble free engine, then i would say your friend should not be concern about money. I mean he should have good budget for piece of mind.

I will use word 'You' here and i refer you mean to your friend ok. So...
If you go for re-bore you can save some 1000 bucks but rebore doesn't last much and its depend on the lathe person and machine who do the honing.

So going for the new bore kit is what i would suggest, but decision would be yours. For crank you can go rebuild, find the best one in your area as the crank if not build correctly will not last long and can worn the bore soon. New crank cost nearly 2500rs.

Apart from this you would have to get head work done (valve polish) in lathe with new valve kit (includes valve oil seal), rockers & cam shaft (if found worn).
Plus new cam chain, cam roller, tensioner, tensioner head rubber, spring.

Head packing, block packing, crank case packing, clutch case packing, top head cover packing, left & right cover packing. Best is buy whole packing kit.

Oil seals whatever is leaking. Head oil seal is must, kick oil seal, gear oil seal, front sprocket oil seal and o-rings.

Neutral patti, crank bearings, con rod, and any other crank case bearings if found worn.

Find a good mechanic in your area who is trusty, and don't get a mechanic who promise to give to bike at shortest period of time and he will do work fast, and any work done fast is not perfect as the quality decrease, its my thinking. So get a good mechanic who do work with ease..

Feel free to ask if u have any concern.

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

@Paul911, nice to see you after a long time.waiting for shoeb2015 also to back.btw recently bought bullet machismo regulator, as you mentioned in some post.it is written 12.8 volt.what does that mean?max outputvolt is this or what? And also let me know what will be the normal o/p volt of our bikes(AC)?is it like rectifier 14+, or less than 14?becuse i am getting lessthan 12 in ideal rpm?that is ok? so i changed tail lamp to Led & high beam indicator to also led? now light is better than before.looking for osram 60+,but not available here,any other make?how is phonix bulbs(hh oem)?

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

Actually any regulator doesn't give output. It is connected in series, there is no i/o. What it does when its other point is grounded it start to block the volts, here the cap is 12.8v. Meaning if the volts is lower than 12.8 than it will release it fully to the HL. When volts exceeded 12.8 then it hold the excess current inside. How it hold? The transistors inside start to short the current therefore it requires ground for it. And therefore it is covered with heat sink because it generates heat when short.

12.8 is perfectly normal as the HL bulbs are tested on 13-13.2v. You don't need to touch the rectifier as the rectifier doesn't use for HL it is for battery which converts AC to DC and the output can be measure on the battery terminals.

You will definitely get less than 12 on idle, why the HL bulb glow low and flicker on idle? Because stator doesn't produce 12v on idle. Increase the rpm and see. With regulator connected you will get 12+/- volts. If you remove the connecting pin from regulator, then test by giving throttle and you will see volts will rise from 12 to 18-19v or 20v may be (depending upon the rpm).

[CAUTION: DON'T TURN ON HL DURING THIS OPERATION, BULB WILL BLOW]

I don't know about phonix bulb. Philips & Osram is what widely used. See online if you can find otherwise use Philips Premium it has same lumen as Osram, its also good. Philips Premium come in pleasure/xtream.

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

I think he mentioned halonix bulb

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

After completing 32,500 kms, bike is due to get serviced. Since today is a holiday, mechanic was on leave. So, changed the oil alone. Will service the bike tomorrow. Bike was running on castrol gtx. This was the first time castrol was used. Today, switched back to veedol take off 4t 20w 40. Cost Rs.245. Engine has freed up now after using veedol. Never going to use castrol again.

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

yes jith_in, i meant halonix 60+.thanks for pointing.
@Paul, philips for extreme and hunk,pleasure not available now with ASS.only phonix brand is with them.

thanks brother for the details,let me know , how to give connection to pass/flash switch?direct from battery? or ac?if i connect from battery,the bulb will withstand 14+ volt?

In machismo it is 12.8 volt, what be in splendor, less than 12.8 v?i mean difference between machismo and splendor rr unit (output volt)?

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

The pass switch is already on battery. Did u installed the regulator? You dont need to change any connections or wires, leave it as it is; until you want something different to do.

Yes splendor rr unit has less output. Slight difference of output will be there in any regulator i think.



This is mine setup. If you see there are two wires coming out from regulator, Brown & Blue. Brown is grounded and the blue one is connected to yellow (AC) wire. What here is need to do is; disconnect the Yellow wire from RR and connect to this Blue wire. Thats it!

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


yeah, little confused here!!! I have to open and see the stock rr wire.i think total four wires,one yellow from alternator coil to rr i/p, other yellow wire to headlight,is it correct? then one for battery charging.one more is there??? may be earth,body also earth.
In machismo r unit,blue wire i/p to regulator and brown ground,then which one is out put to headlight?

what i thought,in machismo r unit blue i/p and brown o/p, body ground.here i am getting Regulator output also to headlight.am i wrong here about colour code ?

PASS switch i meant, headlight pass switch.then i have to change the LHS switch assembly to passion pro,splendor pro type ,with pass switch.

----consecutive posts auto-merged-----


veedol take off is a nice oil.this time my bike is running on it?check your milage also? may be higher than before.

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

Regulator doesnt have input output. Read my previous post again.



It is like this. Its not for our bike but its similar. You need to unplug yellow wire from RR and connect to Blue wire in machismo regulator and Brown to ground thats it. It is the same yellow wire which goes to HL. Don't confuse. Do as what is told. Forget the logic of input/output.

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

Ok ,i'll do as you said. thanks for the schematic diagram.i think RR unit is in series with the circuit.Are you using stock RR unit for battery charging?one more thing ,is it possible to install bigger battery(12/5ah) in splendor?

How to clean connectors?WD 40 will work or i have to file/scratch?
