Thankyou fastbob

Car drivers always think bikes are the cheaper option..........Nope...well not counting scooters

You will be ok with the size

as you know weight disappears when moving to a certain extent

a few weeks and you will be looking at other bikes............thats what Bikers do..........I have had my next bike planned all year

Well Done

Code -C00 is normal running and means no fault

The - (dash mark) in the middle is your TPS (throttle position sensor) if the dash (-) is lower or upper it means TPS is out

like this _C00 ........(no one can find the upper mark on the keyboard )

I would leave the diagnostic plug left in while you ride so it shows you the fault code when the FI ligt comes on

It wont do any harm I run my bike with diag plug in permanently as my clock dosnt work

Oh and you will need a Torque Wrench to get the head studs to the right Lb's

Again that info will be in a haynes manual

Ive just done this job on my bike .....took me 4 hours .(with head off and on desk).JUST removing valves and adding new seals.....but that was with 16 valves

A single cylinder (2 valve??) will be fast and easy compared

You are gonna need a valve spring compressor and valve grinding kit...........you will be able to get away without grinding valves BUT

as said it will increase your compression sealing and directly increase power IF its needed to be done...........and seeing the age of your bike I would say you will benefit from it

you Will need timing instructions ....haynes will have all the info you need

(if you feel resistance when turning over engine by hand STOP and recheck timing)

you "May" need a fresh head gasket.....Again a good clean and possibly a light spray of copper coat will probably work Ok on a 125

If you decide to change head gasket look to see if Cometic do one for your bike......this will increase your compression a tad....again = more power

The Key is Patience and NOT rushing anything

Hi,

make sure you Lube them well.........put them on Dry and they wont last five min
