Well avoid revving the bike while in neutral. The one-way clutch gives up because of this as told by a TVS personnel.Don't know what's the connection between giving throttle and the clutch but this is what i was told.

Dude he is far ahead of being just a mechanic of any sorts. He is an engineer!!

Ok, i dug deeper and deeper about the one-way clutch failures and indeed my friend was right.After clarification with him and through various websites here is what i could understand about the real causes of this issue.

The problem can be attributed to the battery and charging system. When the battery voltage drops as the engine is spun by the starter, the sudden voltage drop can confuse the CDI which controls the coil and send a premature spark to the plug. This in turn gives the effect of advanced timing and a slight kick back occurs, This kickback can put strain on the one way sprag clutch and cause failure in this component. The spark delay unit will cut out the spark momentarily on start up. Thus allowing the engine to get spinning and overcoming the voltage drop problem and sending a spark when the load has become lighter on the starter.Also in many cases a low-charged battery can damage the one-way clutch.

The Sprag clutch and starter issues are related and mostly results from backfire/ignition issues. Which is why it is mostly advised that KS be used for a cold start, when there is more chance of a kickback.

Note: One of the prime causes for the gears and/or the sprag to break is the engine backfiring/premature ignition.So in a way the CDi might be the culprit here which fails in sensing the correct timing during the compression stroke.So my friend advising not to over-rev the bike while using the starter motor makes sense!!

@all - pls excuse me for replying late. i was a little busy.

let me clear things here. i had bought rtr180 around diwali last year. got d delivery 2days before diwali from innovative tvs, bhandup (mumbai). had rhs pulling, front disk noise along with rear disk squeaking, front end noise (was prolly cone-set or fork oil issue) & rear suspension 'thud" noise. i informed the sales executive the day i took delivery after riding it all the way back home & was advised to bring the vehicle to the service center the next day. that day, they were shutting early & were going to remain closed for next three coz of diwali. sope the bike was with me for 4 days (@chicane). the fifth day i submitted the bike at their workshop & was asked to pick it up the next day. four days went by, the problems stated weren't being solved. i had to continuously follow up & check for the status. after being told that the things have been rectified, i would reach the workshop only to find the otherwise. this happened for 4 days with got me boiling & the thing which really blew my lid off was when i was told by the senior mechanic that i had dropped my bike!!!.
as my Mum has studied law & my Dads' friend is a consumer activist, i mailed the firm (tvs) & the dealer to drag them to consumer court & hence got full refund. (@haxor)

but now, i have booked my bike yesterday with ashwini tvs, thane(w) , & will be getting it in white on 9th .
guys, please guide me with what to get checked before taking the delivery (as it was partially my mistake the last time).

@chicane - why wouldn't abs be a retro-fit??

I don't know of the above & my bike has done only 1500 kms.but the gap (revvs) between 2nd & 3rd gear is huge.

What i mean is the 2nd seems inadequate & the 3rd overtly abundant.

i constantly feel this should have been a 6 gear bike.

Almost all the time in city conditions the bike just stalls in 3rd gear.

can anyone please update on the gearing ratio of the 180 or do i need to get anything addressed at the svc.

So, are you sure that this ^^ was the reason in my case??

Are you talking about revving the bike while it's idling in neutral or revving it while hitting the starter. If the problem occurs while revving in neutral it's just terrible engineering. If it were some other country the manufacturer cold be sued for it.

Revving while starting is always a bad idea. Sometimes required because the jackass mechs set the idle too low. I dunno why they keep doing it. When it's set right, a light touch of the starter and the bike settles into a smooth idle. I feel all owners should instruct the mechs to set the idle so that the bike starts wihtout touching the throttle. Don't leave the svcs till they do that.

just now in p180 thread i read people talking about nitrogen compared to normail air in tyres...
in what way is nitrogen better than the normal air? i dont think its available anywhere in new mumbai...is it? navi mumbaikars?

hi friends i am posting this query on behalf my friend.
his mind is very much inclined towards apache among all the bikes present in the market at the moment.
but his confusion is to select which one i.e he is confused between 160,160fi and 180.?
he is a daily commuter and will use the bike daily for minimum 45-55kms and even more.
as u all own this bike and know about its relaiability and milage and maintenence etc etc please provide an input by suggesting which one to go for.. and please if possible kindly let me know the pros and cons of all the 3 models and also the milage.
thanks in advance
regards
gaurav.

Apache 180 is the best choice among the above mentioned bikes. It is a VFM package.
