If you mean hole in carb slide......It can be done, and it will not affect bike negatively, since it will provide richer mix.The FE will go for a toss, but the response will be addictive..

Yup.. Thats it, the hole in carb slide. And since you mentioned about it making a rich mix, I have a small doubt... Turning AFR makes rich right, and this also makes it rich.. So??? I hope you get what im coming at..?

Yep poor FE...let me see i have 5 more liters to finish then i will tell you.As per my calculation i must be loosing 3 to 4 kms /liter..but the acceleration and power delivery make you think it is not tame ZMA...and it does 80 Kmph easily with little throttle.power surge after 5 K rpm is very good....overtaking at higher speeds is easy and you tend to deliberately slow down to accelerate to feel it..even off the block it is good.

Vineeth has a 240cc Joeled ZMA

HALLEELUJAAA!!!! Thank god Indians have never seen the real thing!!!

SRY!!!!! My Mistake!!!!!!
I accidentally said vineeth instead of vishak,,,, Reallly... Sorry!!!!!

No sir, Am least concerned about FE, heck my 10year old kiney gives me 8kmpl...What say???

What i meant to say was... Turning AFR also makes it rich just like hole methode.. So cant we like, you know, bring the hole methode's performance by tuning AFR alone.. Since both of them identicaly produces rich mix? Or is there something more to this than meets the eye(my eye... sorry for being a noob )...

Today, while riding I could smell something burning. I think the smell was due overheating engine. The reason could be low engine oil, which I havent checked. But if that indeed is the reason then I am wondering if I should just add some extra oil now or change the oil completely? The oil is still good to go for now and I had plans of changing to Motul oil, maybe even the 15W50 grade oil.

What do you suggest? Shall check the oil level in the morning and update about the same.

Jusy did the AFR tuning.
Thought just to check what is my current setting on the AFR, turned it fully clockwise till it stopped and counted the no. of turn and it came down shockingly 5.5 turns. Got to know that, why I was getting very low FE's.

This time while checking the AFR setting the engine was not on. Then, turned it anti-clockwise and stopped at 3 turns, just to ensure that from this setting does my FE's really improve.
(Half hour before all this I started my bike to check the cold start rpm and it hovering around 1100. That time I just turned off and went back home.)

Now, after the AFR tuning I started my bike and it started in 1 kick but refused to settle down to certain rpm, so adjusted the rpm and take it to 1200 rpm mark. This time it was hovering at 1200 rpm.
Then, I went for spin after warming the bike for about 2mins and throttle response was smooth.
After few KMS, I thought to check the bike by ripping it and it was good there too but still got hiccups at higher gears.
What could be the issue here? I was getting the hiccups when the bike was running rich and now on lean too.

When returned back home, found the rpm at 1800 mark and just waited for half min it just dips a little to 1700. So, adjusted to 1500 mark and waited for min, it settled there but sometimes it was hovering little bit.

Is my setting fine? Will I get good FE's now? And why these hiccups again ???
Does the hiccup issue may be due to Spark Plug ???

What exactly do you mean by "hiccups"? Power drop at certain speed?

Something like this: http://www.xbhp.com/talkies/629646-post5221.html ??

Yes, similar to this. When I tend to rev high or accelerate immediately by opening the throttle in higher gears it just misses/power dip for a fraction of sec and then accelerates.

Check for oil leaks and also have a look at your air filter. I had the issue resolved after I fixed the oil leaks on my bike and changed my dirt clogged air filter.

So you were running very rich.


Your mileage will increase by a high margin for sure.
You will feel hiccups as you were running very rich before. so 3 anticlockwise turns means a bit lean,That's why you feels hiccups @ higher rpms,i have the same problem before tuning AFR screw,after setting it to 4 turns,now engine is smooth till 8k rpm,dont want to push more than that.

Also as harishsangwan said,check airfilter,if clogged,replace the filter,its 205rs.

LED from philips(5W 4000K) will cost you nearly 1500rs and is rarely available in India.

Definitely 2stroke!!!

Bro try turning to 4 turns setup.
And if still problem presists then try changing your aifilter.
If still problem presists then check fuel line,
Any one of the above is surely the culprit.

And did you notice any change in your exhaust note???
