Do you hear any sound coming while cranking using self start or kicker...?
or is it like it doesnt react.

This is the 3 rd time this has happened in the last 3 months each time if i leave the bike idle for 10-15 mins it started as if nothing has happened....this third time it just refuses to start

.

Whats wrong with my bike guys?

Kicker without pressure generally means lost compression. Have you checked smoke at high RPM? It'll be better if you ask any of your friend to ride behind your bike and look for the smoke..
Fool-proof and safe idea..

Like i already said in the other thread, your engine has lost compression.

Did this happen when the engine was hot?

If yes, it is mostly due to over-tightening of valves. You need to replace the valves as they would be bent(stems). Head should be opened for this.

For starting your bike, use the push start method, it will start. But keep the revs low, you might not want more damage to the engine.

The same thing happened to me, just because one mechanic moron over tightened the valves without me asking for any adjustments + without a feeler gauge!

Also, check ur engine oil level just to rule out engine seizure. (highly unlikely in ur case but anyway)

lose in compression

The problem you stated shows that your bike is loosing compression and no it will not give smoke because it is not related to piston and rings.instead the valve seats are damaged as a result your bike is loosing compression through valves. the solution is to open up the head and clean the carbon deposits. then see that the valve edges are not thin. if they are okay then polish them with the valve seats and they are good till a lakh km s.if they are worn out then install new valves by polishing it with the seats.

Ok i will see by pushing the bike on 2nd gear and yes all my electricals work just fine.And no abnormal sound is coming when i use the self.

Yes it happened only when the engine was blazing hot....ok i will try to push start the bike hope it starts as the SC is a good 100 kms away

.IF it starts can i ride it slowly @40km/hr for 100kms or will it again give up on me midway

.I do hear some tappet noise now but only slightly. Yesterday only i changed the oil

.

No one in the SC uses the feller guage to set the tappet i dont know why

.

Ok no smoke means i dont have to open the engine...thats good

If it happened on a hot engine then most probably it is related to valve train. but you cannot be always sure. when you open up the head see that there are no vertical marks in the bore. if it has marks then the piston has expanded due to heat and this has happened prior to complete seizure. even this condition will not give white smoke only will cause the silencer end to be sooty and lots of carbon deposit. even my bike engine suffered from similar fate on highway but i gave it a 30 mins break and then completed the 500 km trip at a speed of 50-55 k mph without any smoke.
but your case is not similar as there is loss in compression so it is related to valve giving up.
and regarding the valve adjustment using feeler gauge, i have been adjusting my bikes tappet without feeler gauge for 5 years and there is no problem.
you can know whether tappets are correctly adjusted by hearing the sound.
if it is clattery then it is loose tappets.decrease the idle rpm to 900-1000 and see if the engine stops as if it is loosing compression then the tappets are tight.

What oil did you put in there ? Did this happen just after the oil change ?

HeroHonda authorised service should never be adjusting valve clearance without a proper feeler gauge !! How else can one measure spaces like 0.05 mm ??!! The jokers !

**sarbanoxley** · 05-07-2011, 08:16 AM

Yesterday push started the bike and took it to vellore.....But the head mech was on leave so left the bike at the SC.Saw one guy with the exact same problem....poor guy was from andra pradesh when his Xtreme just stopped near vellore (valves bent) he said he never ever touched the tappets all these years.... he also said 2 of his friends xtreme also suffered from the same problem

whats this some kinda design flaw

I use gulf.

No it was not the oil...it happened 2 times before also but as the bike started after 10 mins i thought it was some minor problem

.And yes i did make them use the feeler guage once but they could not set the tappets right even then....Jokers

Hmm valve problems ... rings a bell you know !! ... I have a year old splendor plus too ... and there is a report on the splendor ownership-experience thread about defective valves being supplied by hero honda on new splendors . Mine haven't been opened or checked ever yet . But do read up that thread ... maybe we are on to something ?

Dont open and fiddle with the tappet the SC morons will **** it up for sure. About the defective valves...its possible but what can we as a customer can do about this? i dont know

.

Guys should i change the oil after they open the head for the valve job?

**sibun** · 05-09-2011, 08:03 AM

As a customer we cannot do anything thanks to our government as in this country there is no law for the company to compulsorily meet the warrant defects in the country.
Instead go to a good mechanic and change into new valves as it hardly costs 1000 bucks for the whole work and will save the headache of claiming warranty to which they will never agree and secondly you will be saved from shoddy work of service center.

True.Here local mechs only fleece you its better to take it to some good SC even if it is 100 kms away...i learned this the hard way

.

Finally got the bike repaired....the valves were fine no damage

....the culprit was carbon deposit that led to the valve being open hence the compression loss.

They gave the head part to a lathe to "reseat" or something.The top part of the piston was black they scrapped it off with a screw driver.

What could be the reason for this excessive carbon build up? for the last 10000kms only i use mineral oil for the most part i was on motul 300V only.Even with mineral oil i change it at 1500kms.could it be the petrol

It cost me Rs 445....i did not change the oil as it was just a few days old and the head mech too said its ok
