whereas my friend starts his gladiator in just single self in early morning

zma experts pls shed some light and help me to resolve this issue

I have the same problem with my ZMA too. Because I used self too much early in the morning, the battery also started to drain.

Now, I start the bike using kick start the first time and with choke pulled. After it starts, I push back the choke and slowly open the throttle without stalling to warm up the engine. I warm up for about a minute and be gentle on the throttle for approx 1 km.

I googled for this problem, looks like it could be due to a clogged carburettor. I even found instructions to open the carb and clean the jets. But, I do not want to risk it, but leave it to the specialists. My bike is due for service and will let you know if the Service centre could resolve the issue.
If someone has any solution, do post it.

It is nothing but your bike is not properly tuned. as our bikes are crab tuned and not Fi bikes we require to get it tuned as per our riding style say 1000kms. just increase the fuel flow a bit after setting the idling rpm to 1.4k. Turn it by half. This should solve the problem. It is a trial and error method so keep checking till you get a perfect tuning. If you think that you are losing on mileage then you need to service your bike.

Other users please confirm.

I use choke start everyday morning..idle the bike with choke for 20 secs. and then close the choke. After that the bike doesnt stall.

Jitu, how much oil is less? Did you check the oil quantity when you drained? No need to worry if it is 200 to 300 ml less. Nothing would have happened to your bike.

The engine heating up thing is just psychological I guess. If the bike is running normal, nothing might have happened. Just take a chill pill and enjoy.

Another question, why is the oil very less? Did the service guys put little quantity?

by less oil i meant almost no oil . the oil level was below the minimum level recomended . it was very less (tahn minimum level needed)

"WHy less oil ?" i am also thinking about that . I found this thing on 1 st jan and before that the last time my bike is serviced on november 10 th
that day i asked them to top up the oil but it seems that he forgot it ..

it is not psychological .. i can really feel over heating. Even after 5 km normal crusing i cant touch the engine for more athn 1 sec .. that hot .. is that normal ...?

i have tuned my bike in sep, and it get used to start at single self widout any choke. but now in winter it requires to have choke on, so i dont think that tuning would be of much help, or tuning again will cause mileage issues. friends wat u think on this????

i get mileage of 38-42.

Can you tell me your ridding conditions to get this much mileage....
mine is a mixed ridding conditions and i constantly get 30-33 .... its not that i m sad about it..... just curious to know as to how you guys manage this much mileage is it that u don't pull ur bike to 80 -100 km atleast..

**anmol_1990** · 01-07-2010, 11:20 PM

^^^

i change gears at 3 k rpm and never rip, chek tyre pressure regulalry and thats all......though i mostly drive b/w 60-90 and not more than that.

i just got my ZMA 3 weeks back, its in Run In... every1 told me that i would get an average of 25 - 30 before 1st servicing... but i got an average of above 46 for the 18 litres of fuel that i have put. Got 830 kms in little less that 18 litres....

I ride within speeds of 60 kmph and dont shift gears beyond 3.5 k rpm or max at 4k rpm on highways..

Ya tyre pressure is one of the important factors as well, if u have less pressure ur fuel consumption will be a lot lot more.....

Love your bike to get the desired results....

My 3 months old ZMA is a trouble to start in the mornings. Also it has developed strange problem. i doesnt idle properly, the rpm keeps dropping to 600-1200 range and bike turns off. its weird. showed to SS. the guy tuned it a bit. but the main problem is when i start off with first gear or even rev up in idling it misfires badly. that blank fat fat sound. when i suggested him that it could be a coil fault he agreed immediately and said a replacement is needed but no stock is available.may be wanted to escape the warrany thing.
Now i have bought the HT Cable (High tension) and gonna visit back.
By the way whats the ideal RPM for idling. Manoj and i have set it on 1100 and we get a mileage of 38-41.ia rpm connected to mileage anyway? is it harmful at that level or do i have to increase it to some 1400 ? please suggest.

**ravi@17bhp** · 01-08-2010, 06:33 AM

^^Idle rpm is not related to FE. Set the idle rpm at 1300 when the engine is hot (do not set when the engine is cold).

Always use choke in the morning for cold start and let it idle (with choke on) for 10-15 sec. The purpose of choke is for a cold start.

Jitu, I still need clarification regarding the amount of oil you drained. Please try to quantify, at least, approximately. 200-300 ml less does not harm the engine in short periods.

But in Sep, it wasn't that cold. I also never have the problem in Summer but as winter sets in the problem occurs. I maybe wrong but for me it has worked. my bike is not having cold start problem after increasing the fuel flow. You can always try. it is not going to harm your bike anyways. if you think that your mileage has gone down more then 5kmpl then go to SVC and get it set.

thats the deal.... i used to wonder how everybody gets 38- 40 --> I tend to ride fast.... gear shifting happens at 4 and above rpm ..... thats the problem...
and finally thanks for the check Tyre pressure reminder, i hardly do that... thankz a lot

I want to try this this weekend.

Please let me know, where I can find the tuning screw on the carb. Thanks in advance.

The mixture screw is on the left hand side of the carb. You will need a small flat headed screwdriver to turn it. Tightening leans the mixture and loosening makes the mixture more fuel rich.

The idling screw is on the right side of the carb, it has a large black plastic knob to help turn it.

Typically, on the air screw (mixture screw) more than one half turn either way is not recommended/required, so limit your experimentation to this range.

Running an engine too lean can cause severe engine damage, so if you're not sure, don't mess with it.

What the air screw does is to vary the amount of fuel for the same amount of air that is fed to the engine.

Good luck!
