Info: Spark Plugs

[Raccoon]

Geez mate - is it like you are riding at extended high speeds most of the time?? If not, the plug is obviously going to do more harm than good!! Use it ONLY if your engine is running REALLY hot most of the time!

[honda_vings]

i think if it was dat complicated
den honda must have mentioned a caution with it
i think dey r suitable 4 heavy load riding but not unsuitable for low load riding
still if u think i must remove dis plug i wil use another straightaway( plz. tell me if adjusting d gap cn avoid d harm to d engine)
No , i am not at all going to ride regularly at extended high speeds bt sumtimes ven i ride high speed i try to reach the extreme speed as long as d road allows
w8in 4 ur suggestions

Try NGK iridium-IX if u can get one

@raccon: I meant color of "insulator nose"

[honda_vings]

hey nox
1st thing
i wud go 4 another spark plug only if dis spark plug(cpr 9ea-9) cn harm d engine under normal riding conditions
secondly iridium -ix is nt recommended by ngk nor even by honda for unicorn
if ne unicornian has tried it den plz let me knw

@Mandeep Singh,

I remember reading about "spitfire cables" or something... I think they do exactly the job of handling that amount of current Don't know much about this though.

silly but y not?.......but i got those spitfire[dun remember if the names the same but they do the same job] cables installed on my kristal...along with bosch twin head spark plugs...the results r superb... far better dan using performance plugs alone.....actually dunno if ne1 does such mods 2 any moped so i get whacky nd complete unrecorded results....but wen i got the sparks wid the stock ignition set up...the engine felt as if it was knocking....and the kristals a Dtsi.....so i discovered this wierd thing....the dtsi engines got 2 sparks arranged at an angle(dunno wat angle) so dat there is a straight spark btween them.......but wen u get those twin head sparks.....dese engines make an amazing pentagonic spark.....i saw this wen the mech i was consulting tried to test the sparks with an open dtsi arangement of some sort made by bajaj during the early dtsi days......dunno if this info will b of any use...but still i think i am the 1st 2 notice this so i posted it here

thnx

ok so
i finally went to d dealer
he adjusted d spark plug gap
and d pick-up increased bt not more den wid earlier spark plug
i m quite sure dat acceleration has not improved at all (if not equal).
so in my xperience cpr9ea-9 is equivalent to cpr8ea-9
but if u usually ride wid a pillion den d power loss due to more weight is reduced with colder spark plug.
and wid colder spark plug d acceleration is consistent till 110 Km/hr and den it drops where as with hot plug the acceleration drops after 100 Km/hr
+ point
u must use NGK spark plugs only dey are far better den bosch and champion atleast.

I have got one with me and used it on my apache. the result was excellent. Currently m running regular twin electrode spark plug, as its best for regular purpose and iridium-IX is best for performance usage.

exellent result meaning=?
low-mid acceleration improved?
n did u adjusted d gap or using d factory settings?
nething else u use 4 performance gain ?

Dude, have already answered your question.

• Just toss that plug away
  
• Put in the original plug (cpr8ea-9)
  
• Leave that poor li'l thing alone to do its job
  
• Live happily ever after

It was giving very low vibes, full throttle RPM abt 12250 constant (varies 11500 to 11750 with regular), 0-60 3.9 sec(4.4 on regular). top speed in fourth gear 116 kmph (113kmph on regular). I m running on outer air filter only. removed inner as i bought the bike. efficiency 56 kmpl over 52 efficiency with regular. I m running regular sparkplug as the running is 1800kms yet. I will put iridium to work after 5000kms or after 2nd official service. I just tried it for 50-60 kms.

no vibe difference in uni or else not noticeable
what is outer air filter ?
k & n conical one's ?
mman dey don't filter ur air intake to sufficient level

and racoon
actually a.s.s pple hv a bosch or dis cold plug
after a couple of thousand kilometers i will definitely try d hot plug as i myself misses dat original beats of d engine since d 1st spark plug replacement.

Apache has got two concentric filters. i have remover inner one.

don't u think u r allowing more dust by removing 1 filter
what happens wid more dust ?
does it settle down in d engine or gets contaminated with d engine oil leading to frequent engine oil replacement or sumthin else ?

I clean air filter every 500kms. And atmospheric conditons are also not very dusty. m using my victor with single filter for last 6 years and 30000kms. no probs.
