Identify which model senda we have just bought.

[modd1uk]

50cc on an 03 plate if that helps, has showa USD forks and knobbly tires.

Would like to identify which model it is so i can get some parts ordered.

Do the fairings give anything away - Decals etc?

To be honest, i would have thought those three parts would be the same on all the sendas. I think the main differences between them are probably brakes, tyres, forks and styling differences. Dont quote me though

The JR9B is a 12mm plug, so wont even fit the head. However, if the plug is too big for the HT lead, you can just unsrew the tip of the plug. Im sure 90 degree caps require this.

Id check with the manual or the NGK website about the exact plug, its probably the owners that have found a certain heat rating works better with certain mods etc. but id stick the standard plug in and take it from there.

Same engine as mine, pretty sure if its a 03 its running a mineralli am6. So plug needed is a BR9ES.
Just went through 4 in a week

I know the engine is different on the senda R extremes, as there like 05 bikes or my mate was and had a different engine altogether. although styling parts like that should be fine although things with critical fitting should be thought about before buying, ive bought parts for my 05 off a 03 bike, that dont fit at all

I stand corrected, there it says B8ES. not B9ES

Right guys according to the NGK website..

Senda 50 / R /SM ( standard power ) takes a B8ES

Senda 50 / R / SM ( full power ) takes a B9ES

Which one is it :'(

[tutton]

Ahh well now this comes onto a bit of a issue.
NGK partfinder lists

Senda 50 / R / SM (Full power) 50+ As a BR9ES
Senda 50 / R / SM (Standard power) 50+ As a BR8ES

Personally dont know the difference between standard and full power on a 50, ive been running br9's from experiance and hasnt done any significant noticable engine damage in 10 monthsish.

Do i go for a B9ES or a B8ES ?

[swiftb]

either will do i would of thought. Not a massive difference between them, the dimesions are the same which is the most important. (length of body etc, so not to protrude and hit piston). I have a derbi gpr50. Reccomenends b10es but i have also used b8es in past. Is the plug too big fot the plug cap or has the metal top not been removed from the plug??

[tutton]

Then save your bike from the hurt.
It does make a big difference,

The higher the number ie10 the colder the plug burns
the lower the hotter ie. br8

So if you choose the wrong plug, then your plug gets too hot and burns a hole in your piston. and that is not clever is it.

the b8es etc are ngk plus, its possible the one in it is a alternative manufacturers plug. Id get the ngk if i were you for the sake of about £3 then you know you got the right plug. Sweet, i would also replace the plug cap with an ngk one, again only a few quid as the orignal that came fitted to the derbis is shite. It corrodes causing misfire, non starting etc.

HAHAHAHA teaches me to refresh the page !

Just refreshed page and seen your reply, your bang on about the JR being 12mm thread.

So seeing as you know your stuff..

is it B8ES or B9ES that i buy tomorrow ?

[tutton]

[swiftb]

thats what these forums are for aint it??? share and share alike!

[modd1uk]

[tutton]

Indeed that was what bike shops have come to teach me.
as today i went in asking for a br8 as my plugs were coking, they told me it wasnt recommended unless i wanted to do a piston change soon as it gets too hot

A hotter plug (the 8) will foul less easily. So if you put the 9 in and it was fouling, the 8 will help. And a colder (the 9) will foul easier.

USE THE STANDARD PLUG!

https://www.spark-plugs.co.uk/pages/pricing/ngk_plug_caps.htm

letter on end is terminal type this should help, lb05f should do it, least thats the one i use with a b8 or b10 plug

the cap thats on the bike now should have the resistance stamped on the side

[modd1uk]

You mean the one thats in my hand..just says what looks like " 5 k ", that could well be it.

[swiftb]

thats the one fella 5k ohm resistance. So you need a LB05f. Job done

[truslack]

Don't use the JR9B! I must have left that in the box by accident.

I always used B8ES plugs in it, and it ran fine.
