Tzr125r not reving out

[bazz]

got a bit of a prob, sometimes it rev's all the way up2 13000r.p.m but other times it wont. its a bit strange cuz most of the time this only happen's is in top gear, but sometimes happen's in d other gears, also my rev counter is goin 90 the past wk always hopping up and down, be reading 7000r.p.m then it will shoot up 2 13000, also my indicator bulbs keep blowing along wit d back light.

cheers

Is ur engine sounding like its at the revs that ur tacho says u are? If not replace the cable??

[bazz]

ya wen its not jumping all over d place it sounds 2 b readin d right rev

[Sergeant_barnes]

Oh right...well i no the problem then......its ****ed :D

Wen i get a prob like this i trace the whole journey of the engine. U gotta check things systamatically or ull miss sommit?????

Air=>fuel=>Carb=>reed=>spark/coil/HT lead=>power valve/exhaust......good luck to ya mate. Just hope it aint sommit electricle!

[bazz]

Fuk dit't think it would be that big of a job but i can say its not the
Air=>fuel=>Carb=>=>power valve/exhaust...... cuz had them all out about 6wk's ago, cleaned checked and put back in. has 2 be somthing electricle

[Sergeant_barnes]

Well i dunno m8 it could b......not sure u can get ne manual for the TZRR....for the UK spec version there is a haynes....ill have a look at my manuel when i get home today and see what they say about shoddy high reving. Should post by about half five/six.

Whats weird is ur tacho jumping about....for that to happen either the tacho/cable is knackered or the gearing for it is.....or ur engine is jumpin up and down to.....that seems unlikly tho....if u unscrew the cable u should b able to turn the square shaped wire urself....if u can do it smoothly it aint the tacho. Help me out here dan, fingerz or ne1! im scrping the barrel! Is the action of the throttle cable smoothe? been getting enough oil? do a little chicken dance b4 u ride it?

:lol:

think best wait and see wat the manuel says :idea:

[bazz]

throttle is smoothe, had no prob b4. i'm kinda thinking its more electrical, going through bulbs quicker than i'm drinking pints :cry: wat about my battery would that effect it cuz its kinda fuked

[Sergeant_barnes]

LMAO its kinda ****ed :)

I reckon it could. U need to get urself a multi meter....or a battery charge tester. Ur batt should be at 12 voltz..if it isnt it could shag things up.

Ill check the manual...could be coil, ht lead,

Ill msg l8ter

[Sergeant_barnes]

I typed out best part of my haynes manual last night and then pressed escape by accident and wiped the lot..... :evil:

So ive scanned all the relevent bits from the fault diagnosis and emailed them to ya.

[bazz]

cheers buck. printed them out and i'll take a look at it. i'll let ya know how i get on. hav a battery ordered be getting it on tue, have a feeling it might be d source of the problem

got that proble sorted out at last, all it was, was a bad connection on the coil( ya know the 2 orange wires which join 2 d coil) well that was the prob, so my rev counter working sound now and it rev'in all the way out, happy days.......... :D

[Sergeant_barnes]

Yeh i no the two..im sure i forgot to connect them after my rebore........took me a week of more head scratchin to find the prob :)

Happy riding m8

Sounds like a bad earth somewhere. The bulbs blowing and your rev counter jumping arounds are classic signs of bad earths.

[Spider]

yeah bad earthing can do that on my old peugoet trekker (Yes a Ped) the nut that was on the ignition coil had disapeared and it was earhthing everything my indicators would all of a sudden stop working the speedo would cut out and it would say i had no petrol then brought the new nut which earthed everything and hey presto problem solved!
