The only reason i see why people remove the stock chain cover is that the chain on the ZMA is lengthy and hits the chain case even when there is little slack in the chain.

I think the other pics show a plastic chain cover and there is no comparison of weight reduction to the stock chain case.Its very obvious.

@kaynmantis am still stumped.....what you are going to achieve from this setup on the bike...

Ever clean your chain regularly?.

Yeah,excluding VAT.

I think you had already told the answers.As a style,also easy to inspect,clean and lube chain as necessary,if its closed,you wont spend yur time for opening and cleaning it + 1 or 2kg weight reduction.just my thoughts......

What do you mean by this one? Full naked is better than this.

The pics posted earlier were reference of what i had done on my bike.
Its still very much accessible and can be cleaned easily without turning even a bolt.

(Noting to offend) but the setup (mini-chain cover) on your bike looks only to cover the rear sprocket.

An open chain gets dirty faster than a closed chain system..+ the sprockets also wear out faster....The chain Guard as it's name implies is there for a reason.

You are true but still why many Indian bikes are coming with Half chain guard? also if the owner is read to clean it regularly will it be a problem?

hey aneesh, could you get me a spare for my bike?.it's just a small rubber thing in he cylinder head.

part no 12271-383-000 -rubber,oil seal
byw is there cruicial parts of the zma in kollam?,i need some rubber,o ring for tappet bolt, tappet bolt/drainbolt etc

Is that an oil seal? and you can order tappet bold,drain bolt and other things,but its hard to get O rings.because they come in a pack of 10 or 20 and we only need one for our bike,so they don't order it or if we are willing to buy the whole pack they will order it.and all the o rings will cost you nearly 500rs.yesterday i had gone to svc for picking up my gaskets and some others,i had ordered o rings,but it didn't came,when asked, they told me this.

You can very well clean the chain with half case !!

Other reason, when u put wider tyre it rubs the original case

+1

Bikes that come with half chain case has a O-RING Sealed chain. Anyway the maintainance on Open Chain is much more than Closed Chain.

But there is one plus with open chain case. If your chain is weak or if it gets cut (due to bad luck) at high speeds then in cover chain case chances of you falling is high. In open case the chain will fall down.

Freshly oiled chain will spin oils and splash over your pants or the bike, that thing is there for a good reason.

Re: covering rear s[rockets, as explained above, protection from splashing is required only from rear sprockets. btw, its much easier to clean/lube chain from both top and bottom and not only half. I have taken this in consideration.

True, but closed chain does not MOST IMPORTANTLY tell you the condition of the chain. What you don't see, you don't know. I bet closed chain folks hardly clean/lube their chain. Before anyone jumps to saying "Its not required as often". I say how often do they check, lube or clean. Once in a month, once in 6 months, in a year etc. Some never cleans them and thinks service center takes care of them. That is IF they regularly service. Often service center people will lube them. Not clean them.

My bike had cover initially, within two weeks, the chain was so dirty I had to open everything and clean them, so open seems a better option. Besides chain covers looks nerdy. Granted, the cover does protects better than open, but not by a big margin. Dust and grime has a way of finding its way inside every nook and corner. And dust can act like fine sand paper. So merely lubing is not good enough, you need them to clean them as well.

If you care for the chain condition, then even covered chain requires lubing/cleaning at least once in a month. If you don't care, it'll still run. I have come across people who have never cleaned their chain. My brother use open chain, he never cleaned it since purchasing the bike in three years. Its still running. But I don't want something thats simply running, I like my machine in good condition.

^^^ i bet many manufacturers are listening and will take this point into consideration...LOL
Buddy understand a full chain cover is any day better than half/mini/no chain cover. i never wanted to do away with the chain case but had to... and still not fully satisfied with the half chain cover but there is no other option....
When the chain is covered its not going to get as dirty as when its open and hence the cleaning interval required is much lesser.

Its ones opinion and can't be changed. But listening to 100 people saying the same is no harm...

Answers in bold.

True but when it is closed people don't bother to clean it or even few don't bother to lube it. Thats what Kaynmantis is trying to tell. Its good to keep it open, take ur time to clean and lubricate it. Its applicable only to those who are ready to make their hands dirty and clean the chain and lube it.

Chain Cover

+1....

Personally i opted for chain cover after 3 years, firstly it looks good...

after opting the chain cover I have started taking care of the same....

Before that I was never concerned and never looked at it....

AS once what happened was the servicing of bike was done and they did

not see the chain or they where least bothered....

I somewhere felt the chain was loose but ignored it as i dint see it by my eyes.

But once at 1 am i was riding back home....on quiet road....I was able to hear the chain was rubbing to the chain guard...

so that was the biggest reason...I personally opted half chain cover..

As aneesh suggested Enticer chain cover was a direct fit....but made a hole for the same...

Thanks Aneesh for your help .
