Now get some brake cleaner, take your case back off and spray it everywhere you sprayed the WD-40...

You sure theres not a restrictor there? :wtf: It'll blow (sound loud) if you havent done it up properly.

Whats the spark plug like?

i changed with another spark plug (as the one init was old)
Kieran#23
Does anyone know the sparkplug setting?

Mines on 28 =/
wobbly_trials#24
28 what?

the plug gap should be around 0.5 to 0.6 mm (not exactly sure on your model but 0.6 is usually a safe gap) this equates to 25 thou in old money ;)

oh, fitted it stills misfires + took air filter off even worse.

There is no gaskets on exhaust or engine :s

is it revving? new pipes almost always need lighter rollers as its a shorter powerband at higher revs. if your bike revs about the same as befor itl be heavy rollers... 70's are seriously touchy about roller weight/jetting and it will misbehave when wrong. as for the clutch wd40 would make it slip for a couple mins befor its burnt off...

Thats what i thought.

but i never de-restricted it :S & same revs

also the kickstart can be kicked with the engine turnt on :S
MiNoR cOnFuSiOn#28
did you buy the pipe new?

yes its new and saw no restricter and so i just left it.

there was no gasket between the engine and also there wasnt any by the exhaust =/
MiNoR cOnFuSiOn#30
never had one so cant be sure its got the restrictor there/... that or its a sleve that looks like part of the pipe itself.. some pipes the can itself is a restriction (baffel tube far too small) anyone on here actually got a laser pro?

ether way it should rev a little higher with a new pipe so ajust rollers/jet accordingly.
idle mix will need a tweak but wont be far off..
Kieran#31
bah i took airfilter off and wow fuck! it flooded with oil (the floor)

so could this be my problem?
wobbly_trials#32
WD40, why??

clean the filter out and re-assemble DRY. see what happens

oil should burn off :|
wobbly_trials#34
possible if it has one
MiNoR cOnFuSiOn#35
reeds in my book, only way oil is getting in the filter is dribbeling down from the tank (unlikely) or compression escaping the reedblock back through the carb spitting loads of fuel into the filter. the fuel obviously evaporates and leaves an oily residue.
wobbly_trials#36
yup, a small ammount is normal but if it's wet through then you have a reed issue.
Kieran#37
it was jetted + new spark plug + lighter rollers + new carb + new reed + new airbox :)

now works fine :)

cost me £27.00 as some of it was partly my thought... so they said...
MiNoR cOnFuSiOn#38

Well, atleast im on the road again. :)

It would of cost more... lucky i was under warrenty =/
MiNoR cOnFuSiOn#40
ye m8 thas the main point, snydy work or not they did the job for 30 quid so cant complain. just wish dealers woukldent invent problems. take a pic of the carb if you can just for my own peice of mind, if its a warenty job 1 it should be free and 2 new parts MUST be used so we will all see if its a new carb for ya ;)
