    Step 1:- tighten the air screw and open 1.5 turns out.
    step 2:- start the engine and idle for 5 mins to warm the engine.
    step 3:- ensure the engine is fully warmed and set the idling 1.4k rpm by idling screw.
    step 4:- now rotate the air screw slightly in both direction, and see which direction rpm is increasing. If not increasing and decreasing both side then the present position is correct.
    step 5:- continue rotating in the direction where rpm is increasing. at a point the rpm will be highest and after that it will dip.
    step 6:- at the point where rpm is highest leave the air screw and decrease the idling to 1.4k by idling screw( because the rpm will be high due to air screw tuning).
    Step 7:- If your strokes are constant then decrease the idling to 1k by idling screw else the next step.
    step 8:- If your strokes are not constant lean the mixture(clockwise or tighten the air screw) by 100 rpm to 1300 and then decrease the idle to 1K.

    A slight variation of needle while idling is not a problem. As engine gets old and carb also gets old needle will slightly fluctuate on idling.If valves also leak then also idle will fluctuate.
    In my next post i will post methods for cleaning carb.
    Standard tuning is between 1.5 to 2 turns.
    Damn for 20 hrs daily no power in my place....feels like i am living in karachi , pakistan .

    The RPM dipping part is what i dont see in my bike....it just rises as i turn anti clockwise upto a point and then stays there even if i turn 4 times anti clockwise.....so what i did was after it attains the maximum RPM turn clockwise till the needle dips slightly....then recheck it couple of times by turning anticlockwise slightly to see the needle rises or not...then thats the point i hope is the correct mixture and it exactly how i did it .

    Today rechecked mileage again with 90% uni. sprocket + 10% stock i am getting 46+ Km/lt inside town...this time a friend took petrol to clean something so this figure i am sure will be higher .

    Also never knew changing the air filter will boost acceleration this much lol.

    One bad thing that happened today when i was halfway to chennai the bore oil leaking got worse and the oil was spraying on my legs...so returned back riding slowly to SC ...the head mech inspected and said only on monday he can fix it...told me its safe to ride in this condition just make sure the oil level doesnt drop much.....so went to the lathe he mentioned and to my surprise i saw USHA piston kits LOTS of them in the yellow box just like sibun's snaps...the lathe guy told me for extreme the USHA piston kit + rebore to 1st oversize will cost me Rs 800...even showed me splendor bore kit from USHA and it costs just Rs 1300 .

    Just before i went to chennai i checked the oil level and it has dropped to just below half mark in just 600 kms ...so topped it up a little...then as soon as i hit the highway and 80Km/hr ...it started spraying but the oil level was at max mark when i stopped immediately to check ....i asked the head mech as the oil is coming out is it possible for dirt to enter in that gap...he said nothing like that can happen ....hope he is right dont want to damage the engine again .

              • This happened last week. Turned out pretty funny at the end.
                Day 1.
                Bike fine in the morning, but after riding 50 kms, the battery dies. Had to push start ( thanks HH for removing the very kicker ) and take to the SVC. Got the battery recharged. Things looked fine for the time being.
                Day 2.
                Battery started feeling feeble. In the evening, I had to ride 50 kms back to home. At midway, heavy rains approached and I took refuge at a friend's home. It was late when I started there. And voila. . ! headlight aint working, nor does the self start. Almost sure indication of a blown RR. Was real pissed. Left the bike there, took the bus and came home.
                Day 3.
                Went to a spares shop, bought a new RR, a new chain kit and went back to the bike. Push started it and took to a mech. While replacing the chain, we found the alternator O/P wire caught between the front sprocket and was broken. Reconnected it and HL was glowing
                Returned the RR to the shop and he repaid.

                Costs involved
                New RR - Rs. 340 (got repaid)
                Rolon chain kit - Rs. 900
                Labour - Rs. 200 ( All workshops were closed that day. This guy was the only one working. And he ripped me off )
                MOTORCYCLING IS AS MUCH ART AS IT IS SCIENCE

                  Why are you not changing the packing and stopping the leaks.
                  It is an old saying " A stitch in time saves nine" and those who have said it were not mads or under some drugs.
                  I had told you that USHA pistons are available.
                  Those idiots at service center will try to clear there stocks. But you must be vigilant enough to know about the markets.
                  Your bore kit was changed. But in my friends case, as soon as the bike started smoking(slight smoking at 6k and above) at 40k, we just opened the bore one day at night after returning from office at home and installed new rings by light honing.
                  The bore lasted for 1 lac km when recently we opened and overhauled the complete engine.
                  So always try to mend when the problem is small.
                  Dust will not enter as oil leaks because of pressure from oil pump.
                  Your rpm is not dropping because of carb. Clean it by following stunner carb cleaning guide in DIY section.

                  My air screw is at 1.60 turns from full tight.
                  Why are you asking. Each bike differs by a lot of margin.

                  Yes it is original waxpol wax.
                  It is the finest wax and has no abrasive.
                  Provides superb protective coating. You must have seen from my joy photos.
                  No, your tuning is correct. Ride and see if the engine revs freely.

                  @all- There has been a lot of debates on spark plug. So the detail is here:-
                  NGK- As all know they are good, but they have a problem. They are the first to get shorted if slight mobil comes in contact. If your engine is consuming light oil, stay away from NGK.
                  CHAMPION- They were previously made by MODI and horrible. But the new ones are made by FEDERAL MOGUL and are world leader. They are on par with NGK. They are the manufacturer who are the number one in almost what they manufacture. They have many innovations in the field of automobiles.
                  In my JOY NGK fails but champion goes on working without any problem.
                  They do not get shorted easily and last quite long. Without knowing do not talk ill of a company.
                  For knowing FEDERAL MOGUL VISIT Federal-Mogul - Spark Plugs.
                  MICO- They are good but are usually colder than NGK and CHAMPION. They are good but slight mis-fire is observed at higher rpm. They are the last to get sorted and if your engine is drinking oil then use these as champion and NGK will get sorted.

                    I spended 100rs extra for that waxpol and that too sawing yours HH joy polished with waxpol and motomax. after apply with sponge can i use to wipe or buff with cotton waste or glass wiping soft cloth??
                    today i was shocked this rpm was setted just 1 anti clock wise from full tight. I forgot to count the turns when i am busy to stable the rpm. by adjusting again again to stable rpm i setted to 1 full round fro anti clock wise. today only i know that. is that a problem am in need to post sparkplug photos again.

                      Yes i am taking it to SC tomorrow....the leakage started right after they installed my new bore and its been like this for the past 4.5K....the head mech says the 10inch screw on which they install the bore its thread is gone...so they gonna open the bore again tomorrow and take it to lathe.

                      Thanks for confirming that no dirt will enter the gap and destroy yhe engine.

                      The bore guy asks me for Rs 800 and just ten mins ...he will rebore my old bore with USHA piston....all say it depends on the skill of the guy who is doing the rebore....the lathe guy said nothing comes close to USHA...so i am kinda thinking if i can go ahead and rebore my old bore with USHA piston 0.25 size .

                      sibun ji you are right about carb being dirty cause when you asked me earlier to remove the fuel screw to check the o ring i could see black stuff on the tip of the fuel screw...but problem is the SC head mech is reluctant to touch the carb...i read the guide of stunner and it seems simple on paper...if nothing works out will get my hands dirty with help of some local mechanic just to make sure i dont fook things up...i actually took it to this local mechanic and he refused to touch the carb saying if something goes wrong i would have to buy a new carb for Rs 4000 and told me to leave it alone ...will sort this problem somehow .

                      one surprising thing is after tuning i was getting 47km/l inside town so thought i will easily get 55km/l at least on the highway....today i went to chennai to visit a friend in hospital and used this trip to check the mileage on the highway thoroughly...to my surprise i am getting just 50.30 km/lt on the highway ...that is only 3.30km/lt more than in town ... i tried to keep the RPM between 6000 - 6500 most of the time like you.

                      Good to hear CHAMPION is a good product...will try to find one next time.

                      @ATHUL I bought the same box fr less than Rs 90 here ...used it 3 times i think ...looks like this box will last me for another 10 yrs .

                        I saw a guy giving a demo in front of sai motors a couple of weeks back .

                        One of my friend had it on his Kinetic blaze , it did more harm than good . It used to beep and alarm would be set off for no reason at all .

                        Even if a stray dog touched the scooter , alarm would set off . It was a total nuisance.

                        • Bad idea man. It'll just drain your battery in due time. Hero always offers this security system with their bikes but I've seen loads of them remove it after a while. It does more harm than good. Besides, once people know you have this alarm system installed, they'll set off the alarm intentionally just for kicks. My suggestions, don't do it.

                          But if you still want to do it, go to JC Road, you'll find plenty of them there. Xenos makes these security systems I think.

                              Double check DPR?? If your bike is cbz-xtreme The no. is CPR-8EAGP-9 cost is214/ and made in Japan.

                              CPR is 10mm and DPR is 12mm thread . For CBZ classic or star,karizma it is DPR


                              Now I am using this GP with AX-7 oil Very smooth feeling.

                                Ok, I will help you in finding G-power for your karizma.
                                Tomorrow, i will tell you the place to get your plug.
                                Also i read about your cable getting cut. Since they are not under warranty and hero has stopped supplying only the inner cable, so you have to buy whole cable.
                                But there is a way in which we can do the work in Rs.20 only.
                                My friend stores the inner cable as he orders them from a company in cuttack who specializes in inner cable. So if you want you can go to my friend's shop and you can get the inner cable for Rs.20.
