tried,.... BUT IN VAIN.
So, is this a common problem??
I dont think so.
Any Guru's out here who can say something more concrete???

Something unusual which happened for the second time today on my 2005 model ZMA.
I was riding at close to 120+ and suddenly the engine stopped. Opened the tank to find very very little petrol. tried starting it but in vain. Pushed the bike for a kilometre and filled petrol. Tried starting almost 20- 30 times (with and without choke), but in Vain

. The engine almost goes to life and then dies.
Finally put her to rest in my Office parking lot. Came back after an hour and she started in just one Kick.

This has happened once earlier at similar speeds.
I dont think this is normal. Can someone throw some light on this?

Thats due to something called 'Vapor Lock'. In simple terms, the carb is gravity fed and the pipe handles liquid fuel. If a petrol vapor bubble gets trapped in the pipe, it will not allow fuel to flow. The vapor forms if the engine gets heated either due to sustained high speeds or very low speeds in heavy traffic and the radiant heat from the engine evaporates the fuel in the pipe. In your case, it seems more of a case of air-lock. The fuel tank was drained dry and so air got into the pipe.

Remedy: Switch off petrol, pull out the fuel pipe end that goes into the carb, open fuel tap to let a little petrol flow out and re-connect the pipe to the carb.
Leaving the bike for a couple of hours allows the engine to cool off, the vapor condenses back to liquid and so petrol starts flowing again.

I have also started getting this problem. many a time, when i'm in 2nd gear (accelerating constantly), the gear just slips to neutral and makes a huge noise (obviously). It used to happen on my Pulsar from 5th cog to the 4th but was rectified. What could be the issue? My clutch kit is brand new. done some 4000km on it till now

Usually called the 'fool's neutral' but the ZMA gearboxes are not known to be prone to that. Probably a worn-out shifter dog in your case. (Have you been up-shifting from 1st to 2nd without using the clutch?) Get a competent mechanic to do the work. Would mean opening the gear-box.

Old Fox, Thanks for that lucid explanation.

**ravi@17bhp** · 03-12-2010, 11:46 PM

OF Sir, those are very valuable inputs.

When I was doing 130 speeds on my ZMA some time back, suddenly I noticed the rpm needle hovering at the redline and I suddenly dropped the throttle and the engine stalled immediately. The engine started only after 20 min. I have been thinking that the cause of the engine stall was due to rpm limit. Now, I am thinking was it because of the same air-lock you described above?

Old Fox, thanks a lot. That makes complete sense now. I dint know this happens in Petrol engines too.. after all, its physics.
ANother main problem I face is petrol leakage when the bike is parked. I lose a lot of petrol if I park it with the fuel-cock lever left in RESERVE position.
Last night I parked the bike on Main stand and apparently forgot to switch off the petrol. In the morning, when I removed the stand, there was almost 50ml leakage immediately. Worries me. Any suggestions?

Well, this problem is new, I'm not sure if my gear shifter cog is worn out or not

and I don't shift without the clutch in lower gears, I do it sometimes only from 4th to 5th with throttle fully closed (no blipping of the throttle also). Is clutchless gearshift harmful?

can someone plz tell me whether the "T"(thats wat i suppose its called. it is the black colour thing exactly under your handle which connects the handle and the forks.) of the cbz or hunk can be fitted to the karizma????

I suggest you check to see if you can use the ZMR's upper T and clip-on combination instead, if you are looking to improve the looks.

Hopefully it will be a direct fit not involving any hoopla.

Meaning to source ZMR parts for my ZMA. Problem is ZMR parts are still pretty scarce, at least in Mumbai.

Hello fellas.

Greetings to all of you.
Planning to buy a bike and almost zeroed on ZMA (other 1 was P220 DTSi).
But then I heard FE of ZMA is 25~30 KMpL.
This is scaring me and I have put my decision on hold.

Please put some light on this matter.

P.S. I know ZMA is not meant for good FE, but I won't be ripping it all the time.
And 25~30 will certainly hurt a lot to my pocket.

35~40 KMpL will soothe my mind n pocket both.

The latter is what a well maintained ZMA actually gives...don't worry!

u sure go for zma-r, mileage of zma-r is in b/w 35-43....i get always 40 kmpl......u have to ride it properly and not rip it , always change gears before 4 k and see wat amazing mileage u get.....

i'm from pune actually...and i think the situation regarding the spares of the zmr is no differrent here...in fact...i'v seen only one white zmr in pune uptil now from the time it has been launched...
anyways coming back to my main query....
i needed a confirmed answer whether the T of the hunk or the cbz can be fitted to the zma...once i get the solution for it...i can straight away go and get it changed...by the way guys,should i go and ask hero honda directly?????need some suggestions...
