Get Castrol power1 2T in foil pack of 40ml.(or in plastic can if you wish)
Add 1.5ml of acetone per liter of petrol in tank along with 2 ml of 2T oil per liter...You will get the same effect if not better.
I am using this brew in all my engines.

I got the acetone (reagent grade) from a lab supply store in college-street here and I have more 2T stock than I'd ever need

. I am only hesitant about the 2T ... what would be the effect of it ( or any oil ) on the catalytic convertor ? ... you know 4-stroke exhausts are not designed to handle oil residue .

Your observation is right, but at 2ml per liter it is very less to affect..any 4 stroker burns a little bit of oil escaping through the rings,or through stem seals, and one incidence is enough to kill the CC.Severe vibration, bad petrol, misfire,rich AFR mix,all go towards killing the CC..In our situation we have everything happening and so the CC of old bikes & cars are already dead....
assuming a bike gives 50 kms per liter, of petrol.....for 2,000 kms it will require 40Liters,and at 2ml per liter of 2T it will burn approx., 80 ml of 2T...Normally at 2,000 Kms most 4 stroke bike requires top up of engine oil varying from 50 to 200 ml...which is equal or more than the 2ml per liter of 2T.

Normal air contains 78% Nitrogen...you may try and post results of the difference you experience.

Time to get moving..

Been nearly 500 km since I bought the 9450 km old ZMA R .The only change I'd done was to get an NGK Iridium plug(that's as far as performance parts are concerned-have changed H/L bulb to 55/60 and park bulbs to LEDs) . Now it's time to make some changes and I hope to get help from you guys .
The mileage I've been getting is below 30 for 99% . The last time , I filled for 50/- and rode slightly sedately (no wringing the throttle , occasional bursts in 3rd and 4th gear , max speed 80kmpph for just 5 or 6 secs a couple of times.) and got 32 kmpl . That's the max I've been able to get .
The guy who sold me the bike had said he hadn't touched anything except to fit a ROOTS remote lock .
Today I checked with the AFR screw and found it at 2.5 turns out . Now , that's odd since I had adequate power ( my previous bike was a P180 classic) and the mileage is less than adequate . I've set the AFR screw at 3.5 turns out and want to observe for the next 2 petrol fillings.I checked the air filter and found it dirty . Since my Vacuum Cleaner's pin is broken (due to be repaired later today) I couldn't clean it . I've posted a pic of the same . Will a cleaning do or do have I to replace it ?
I was told that the 9000km service was done but I'm taking it with a pinch of salt .
Anything that can be done at home without keeping the bike unusable for a whole day will be done by myself.For other servicing , I'll be handing over the bike to a team of technicians who were previously at HH ASS and have now opened their own Service Center.
Points I've noted.
1-Change oil
2-Clean petrol tank
3-Clean/change air filter
4-Clean carb
5- Clean/Lubricate chain
Ride wise , the bike is OK and pls tell me if I have overlooked anything.
Thanx in advance.

awwww

2.5 turns AFR setting and you are getting less than 30kmpl how come?
as many people said 2.5 turns is lean so we should get more economy isnt it???

even myself having 2.75 turns but havent checked the mileage yet.

@psr sir please help

That's why I said it's odd . Now I'll check @ 3.5 for some kms.

Guess you ride in city.

If yes,then its normal to get 30.

Today I checked with the AFR screw and found it at 2.5 turns out . Now , that's odd since I had adequate power

How did you find it out? You calculated the clockwise turns? Did you checked spark plug color?

I've set the AFR screw at 3.5 turns out and want to observe for the next 2 petrol fillings.

Good idea.

I checked the air filter and found it dirty . I've posted a pic of the same . Will a cleaning do or do have I to replace it ?

Guess a cleaning is enough.Not so dirty as mine.

I'll be handing over the bike to a team of technicians who were previously at HH ASS and have now opened their own Service Center.

LOL,Super like that.

1-Change oil

Which engine oil are you going to use?

3-Clean/change air filter

If you are ready to spend 200rs,then i would suggest you to get it replaced,after that you want have to worry about the air filter area soon.

4-Clean carb

Only do it if they are experienced in it.Otherwise you will end up with bad results.

5- Clean/Lubricate chain

Clean using diesel and apply Bearing Grease instead of Engine oil as psr sir said,it will redice noise by50%,Remember do not put used oil for lubing chain,it will increase the wear of the chain.

bro..juss let me know if u come to know how to get more economy..
one of our frnd told me to check same ...but still any thing for bike i would like to know..
thanks..

totally agree with u my frnd...me too using grease for chain..and its noise is lesser than before....today only one of hh techni. told me not to touch carb if there is not any problem.

Plus, some of them said Michelin doesn't make tires of those sizes, I quietly left. Please recommend the ones which you frequent.

OT: Today evening, saw an xBhpain on a red ZMA-R. Desc of the bike - aftermarket exhaust, xBhp logo on rear mudguard, black raincoat, with a bag/something tied up to the rear seat with a bungee chord. A KA 06 registration. Your exhaust note was quite interesting, K&N filter? I was next to you in the busy traffic for a couple of seconds (it was raining) - infront of the Le Meridian hotel, Near Windsor manor hotel, Bangalore. My ride - red, stock ZMA-R. If you read this, reply!

hey man you spot me, was on a short LONG ride from kerala to Ban so the luggage. Even i remm your Neatly maintained zma. I guess you where on ma right side, is'nt it?

Yes because tuning carb to optimal settings is not an easy task.

Yes,city riding.But to and fro work(3.5 km each) is sedate .

Turned clockwise till tight.Then turned anti-clockwise
NGK Iridiunm is mebbe 250-300 km old.Pics of the previous plug is attached

Guess a cleaning is enough.Not so dirty as mine.

Is it a normal 9500 km dirt?

LOL,Super like that.

Those guys normally take only company spec jobs.I had to tell them "at my risk" even to put in NGK Iridium and 55/60W H/L bulb.

Which engine oil are you going to use?

Not yet sure - which do you suggest?

If you are ready to spend 200rs,then i would suggest you to get it replaced,after that you want have to worry about the air filter area soon.

Is it a normal 9500 km dirt?can it go on for a couple of thousand kms ? (Service chart says 'change @ 11000-11500 km')

Only do it if they are experienced in it.Otherwise you will end up with bad results.

Gonna try psr's 'Acetone+2T oil' trick . I am open to almost all experimenting .(had installed a YEIS type thingy in my RX100years before the company came out with one in India.The idea came from the RTZ's 'powerbox' . After putting 2nd oversize piston-where 1st oversize would've been enough- , starved the oil pump to it's sweet spot - WOT on Palani-Pollachi road @ 125kmph , I think 135 on speedo , on way to Kodai from Kannur , no sign of any smoke !!)

Clean using diesel and apply Bearing Grease instead of Engine oil as psr sir said,it will redice noise by50%,Remember do not put used oil for lubing chain,it will increase the wear of the chain.

OK , Thx.

You had filled petrol for Rs.50/-...so approx. 750 ml and you got 30 kms ..so if you fill 1 liter (1,000 ml), you will get 40 Kms per liter...it is a good FE for ZMA.

Today I checked with the AFR screw and found it at 2.5 turns out . Now , that's odd since I had adequate power ( my previous bike was a P180 classic) and the mileage is less than adequate .

To look at ,....the Air filter seems ok...but if you have doubts then change it..it is not expensive and costs only 205/-.

1-Change oil
2-Clean petrol tank
3-Clean/change air filter
4-Clean carb
DO NOT DO THIS IN THE LITERAL SENSE. Ask SVC to use carburetor cleaner spray and not to touch carb or it's parts,unnecessarily.
5- Clean/Lubricate chain

Thanx in advance

The picture of your plug shows that you are running lean AFR only.esp., the last pic..your Ground electrode looks COOKED.You had been running lean,

Have a new Air Filter, Set AFR screw to 2.5 Turns ,and ride at 3.5 K to 4 K RPM...Never do sudden increase in throttle. SHIFT TO 5 th Gear at speeds of 45 Kmph or more.

**kariznin** · 07-03-2011, 10:14 PM

@ psr sir : just went to remove the plug and take a picture of that, it was too tight to be removed. Tried a several times but didn't succeded.
Then, pluged in the plug wire and tried to start the bike. As, using the bike daily it starts in first self and then I used warm the bike for around 2mins but today it didn't started at all.
Made 12-15 kicks then too it didn't started, after that I pulled in the choke and then it started in 2 kicks, so I warmed the bike using choke for 2mins and then disengaged the choke. Bike rpm hovered around 1200 and then it stalled.
After that I tried to start the bike using the kick, it didn't started after 15-20 kick trials. Then, I turned the fuel knob towards reserve and then tried, it started in 3 kicks. My bike just ran 115KMS in 7.58Ltr (if subtracting reserve then 6Ltrs) of Speed petrol. Again the FE's are very low sir. What is the issue with my bike these days, it is behaving very abnormally.

P.S : When I warming the bike using choke, I was putting back the toolkit in it's place and placed the seat, suddenly some 'puk-puk' sound came from the exhaust twice or thrice.
