Sir,
I'll try to make a slot for tps. But I've no idea about which tps I should use. Any help will be appreciated[emoji2]. And again, thanks in advance[emoji7]
You are awesome[emoji847]

The end of the shaft is not slotted to accept a TPS and so you may not be able to fit a TPS with this Carburetor.. Alternatively by cutting a slot into the circular end, you can connect a TPS..still there is another small plastic part which is a 90 degrees offset unit to connect the TPS...here is a picture to explain the same..You can see the protruding end of the throttle blade axis which has the vertical slot and part 17 which is the 90 degrees offset plastic piece to make a precise connection to the TPS...Of course this small plastic off set piece is required since the throttle actuation slot and TPS slots are originally 90 degrees offset...so while forming the groove on the shaft you can do the offset correction easily...by cutting the slot in line with TPS requirement

Sir,
I have removed the cap where tps can be connected. I'm attaching a pic after removing the cap. If you think i can attach a tps here, please let me know[emoji2] (sorry about my English).[ATTACH]241541[/ATTACH]

One way to get around this problem is to fix 1.8 K resistor from ground to center point of connector and 3 K ohm from the hot (+5v) end to Center point. this will give satisfactory running , though not equal to having the TPS.

Pinaki sir,
I would suggest a small addition to this : Warm up the bike in neutral for 2-3 minutes before removing the dipstick. This will ensure oil has circulated enough inside the engine. We should be having adequate oil after the warm up. Please correct me if I am wrong.

When filling oil after draining out the old oil , fill by the dipstick , NOT by volume . The level should be kept in-between the min-max marks of the dipstick . It should also be checked from time to time that the oil level is maintained between those marks . The process to measure with dipstick is given in user manual , but I shall repeat here - With bike in main-stand on level ground , unscrew the filling cap and withdraw it . Wipe it clean with clean cloth , re-insert the oil-cap into it's home until it comes to rest on it's threads - but do not screw it in at all . Now withdraw it out again and check the oil-level at it's tip . The min-max marks are marked on the dipstick . Oil level should never go lower than minimum mark or exceed the maximum mark .

Sir,
Do I have any other option than changing the carb to stock one? When I bought the zma before some months, the afr screw was jammed and i was getting FE around 20 km/l. My mechanic drilled the afr and put a new one. But he told me that a part called atomiser is damaged and I have to replace the carb. So, I decided to go to the used parts store because i had already spent a lot of money in my bike. I was not familiar with zma or any parts of it at that time. They gave me this carb saying that it is zma's at 1700rs.

... I always make sure that I drain the entire oil out of my engine before refilling it! I use motul 20w50 semi synthetic oil (1 ltr) to refill !

Atomizer! Maybe he was referring to jets.confirm once you will get those in parts. It will cost around 500 RS approx.

The TPS adjusts the ignition timing depending on the throttle position , in ZMA. without it, the performance will be slightly compromised and will not be same as stock one...the TPS is a continuously variable 5 K Ohm resistance with one end connected to ground, the other end connected to + 5 Volts and the center variable point connected to the CDI internal circuitry...Leaving it open can affect the ignition timing and performance but will not cause any
harm...

This carb you have , has electronic choke and single Throttle cable type...if you see the other side of throttle actuator, there is a capped portion which is meant for attaching the TPS.The Vacuum pickup point is also situated on top side of Carb....Since this carb., is not original meant for ZMA you have received without it..Try to get a Carb., meant for ZMA since TPS does make a difference to riding experience in ZMA.[/QUOTE @psr
Sir I'm using the same carburetor in my zma. Will it do any harm to my bike?

The AFR setting will vary depending on engine vacuum and compression, as also the Air Filter porosity and cleanliness. The stock setting to begin the tune is 3.5 turn like you did, and adjust it for the level of FE and acceleration required. The Rust deposits seen in the float bowl is not a good sign...it means there is rust inside the Petrol tank.. If it is so then over a period of time it will start to leak through holes in tank and will also plug the Petrol tap filters and very low to no petrol flow will be there...So check for Rusting inside tank.
The stock Karizma came with 20w40 and using a grade above w50 will make the engine sluggish and a slight drop in FE. The oil deposit inside Air Filter box is directly proportional to the amount of Blowby in Crankcase..It there is a pool of oil in 5~6 k Kms then suspect blowby due to Piston Compression ring leak...in other words your engine may be getting worn out OR your Piston rings are not free, and stuck in the grooves.


Unless you open the clutch side case and inspect the condition of clutch bell and bearing you will not be able to judge it's condition..You can get it done at ASC or with a Mechanic with good knowledge and Good TOOLS.
