Re: The Honda CB Twister

yup...it will be better to use pulser plug cap of 1kΩ... but which pulser cap to ask for? will the cap accommodate the NGK plug properly?...i mean loosely fitting spark plug inside a cap wont be good thing. any idea what is causing the resistance to increases over a period of usage....i mean why resistance does not remain same or even decrease?

Re: The Honda CB Twister

Thanks for sharing these useful links...I plan to read whole splendor thread in free time !!

Re: The Honda CB Twister

Mr.Sachin & Mr.Pinaki.Despite the symptoms you'd mentioned,I experienced some more.I'll list them down in total:

1)engine stops with a faint tic-tic sound(louder near the spark plug)
2)shock felt over the plug cap
3)engine gets rough,noisy & hot due to deficient ignition.
4)pick up falls(I felt a 2bhp loss)
5)feels as if you are about to run out of gas(I turned the knob to reserve twice)

If anyone comes across any of these symptoms,don't panic.The first & simplest thing you can do is 'change the spark plug cap'.

Anyway,when I mentioned this problem to the servicemen,they didn't change the plug cap,but insulated the cap with a tape.Somehow the error was rectified.I wonder how much did this silly problem mislead me.I even thought of an engine failure.

Buddies,thanks for response.

Re: The Honda CB Twister

This one - I think all of them use the same ... and it fits our bikes just nice . Remember that Bajaj's plug cap and the rubber boots that fits it comes in seperate packs , buy both . It's resistance value shall be marked on it .


( Pic is from psr'jee )
Problem occurs when there is rust or tarnish or breakage on any of the various contact points , the electrical resistance of the plug cap climbs . Then the sparking current from the ignition coil just crawls the surface of the plug and cap particulcarly when they are dirty and wet and finds ground on the engine case - following the path of least resistance . So it doesn't go through the spark plug and and you don't get a spark .
Change it , tape fix isn't dependable and likely to strand you on the road on some rainy day - which is the worst time to deal with such things ( i speak from bitter experience ) . Even a cheap ₹25 swiss , top etc local made cap is better than your mechanics fix . Also try to maintain the exterior of your spark plug clean and rust free .

Re: The Honda CB Twister

Ok, an update on the mileage and bike behavior
The earlier setting of AFR screw was \ and i had the black smoke( and bike not responding to throttle ) issue so i tuned the screw anti clockwise based on the suggestions from spark plug reading
1. with another 1/8th towards anticlockwise the bike not responding issue was resolved but i could still feel a little ( noticeable but not major) and i got a mileage of ~47kmpl
2. with another 1/8th anticlockwise ( AFR setting approx --) i could not feedl the bike not responding issue and the throttle response was good but i felt a drop in pickup , mileage : 39 kmpl
Here is the tip of the sparkplug after AFR set to -- and run for ~50kms ( sorry for the photo quality )
Do note that the mileage checks were done only for one round and i had ridden the bike with a pillion rider for 40-50% of the time


I was reading the thread on the plug cap and brought a pulsar 1Kohm one and use it my bike and also got a new airfilter and replaced it, now the bike response seems to be good. I tried to tune the AFR based on Sibuns procedure but couldnt make out the highest rpm by listening and i felt there was a whole 180deg setting where the idling seemed be higher and fell off on both sides so i have set it back to original setting of \ and the bike doesnt seem to have the lag and black smoke issue I will need to check the mileage though

Here is the snap shot of the old and new filter, the bike has run just ~4.7K but i see there is quite a lot of dirt in filter, let me know if you guys think that old air filter is done with its life or if i replaced it too early
Air FIlter Front ( Top is new one, bottom old one )


Air FIlter Back ( Top is new one, bottom old one)

Re: The Honda CB Twister

since a new Air filter has been installed.....you can set the AFR screw to either default factory set position....or around default point where you can sense highest RPM. old filter looks dirty but it can be used by cleaning a bit. DO NOT TRY TO WASH IT with water...because its a paper filter and will get damaged. you can lightly tap it on floor so that any dry dirt falls out. take your old shaving brush(DRY condition) which has soft bristles...just wipe it lightly on dirty surface of filter. this will clean some dirt stuck on surface...and another 3k km can be used.

Re: The Honda CB Twister

Hi pals,can anyone mention the procedure to replace spark plug cap.Also which variant of pulsar's plug would suit Twister?

Re: The Honda CB Twister

check the resistance of cap...it will be mentioned on packaging box...or you can measure it using multimeter. if its 1k then there should not be problem. Post a pic of cap and package box if possible.

Re: The Honda CB Twister

Yes , it's good . Swiss is an aftermarket parts manufacturer with good reputation and quality . But any particular reason for not getting the Bajaj genuine part ?

Re: The Honda CB Twister

Nothing specific,bajaj showroom is far away from home.Swiss plug's resistance value couldn't be found on the package.I asked many dealers & mechanics for low resistance plug but they don't even know resistance's meaning.By the way,since this cap is aftermarket,I would change it soon.Which one should I prefer-pulsar or honda or...?

Re: The Honda CB Twister

Today I bought pulsar genuine plug cap of 1kOhm.Currently I have a swiss cap on.I don't know it's resistance value.I'm going to compare performances with the 2 plug caps & find out the better one.

Re: The Honda CB Twister

what is the price of pulser cap and which pulser model is it made for?

Re: The Honda CB Twister

The cap costs Rs.56 & its a common make for all pulsar models

Re: The Honda CB Twister

OK...is the pulser plug cap able to hold the spark plug tightly inside the cap....like the stock twister cap? did you observe any loose fittings between the two?
