Im almost finished my 125 now I never tried to start the bike as the clutch cover was off when I got it. The previous owner said the bike was running but needed piston and rings.
Here is a vid she pops and cracks but wont start. The timing is correct I have nice spark
What did I do wrong?

will the 125 at least start with the 87 250 carb just to rule out carb problem?

it should, providing it fits good in the manifold and the air boot.

she let go with a big bang :( back to the drawing board

What do you mean by "she let go with a big bang"
-
well she didnt let go it just went bang really load ears still ringing
-
do you have an exhaust pipe and silencer on this bike?
-
yes stock pipe allready checked i thought it might be blocked but it isnt. Im trying to get the flywheel off now i think it may have sheared the keyway

their is no thread internal for the puller to thread into? Do I need a three bolt puller to get it off?

up to the shed to build one of these let ya Know how it turns out wont be pretty
-
I ramble a bit when frustrated just tell me to shut up!!!!!
-
too many beers last night. I did make my tool Im pretty sure i said it wouldnt be pretty.
I still cant get the flywheel off. Is their a trick to removing stuck flywheels my 250 came off very easy compared to this 125
Can I heat up the flywheel without wrecking the magnets ??
I have used alot of force and the flywheel looks like it needs to be replaced now as too many beers and to many different pullers have taken their toll on the flywheel
heres the tool im using its a copy of the tool shown in the manual I actually bent the first one this is mark 2

Just watched your vid from post #1.
Doesn't look like you are feeding it any fuel.
Put that flywheel cover back on, get on stand and when you kick it - open the throttle all the way. Try it.
-
I never heat them..
If I get on that is really stubborn I get it all set up then tighten the middle bolt really snug.
Then I take a heavy hammer and give the middle bolt a sharp hit.
If it doesn't budge, tighten the bolt some more and hit it harder, repeat as required :-D
-
ok i will try that i really want to get this flywheel off i wasnt feeding fuel as it was backfiring (iwas scared) it just didnt sound right
-
tightened her up again and hit with hammer again and again. I have bent my bolt i was using Im sure i shouldnt be hitting that hard. Got me screwed
-
WOOHOOOO just needed a few more beers I think.
I welded another bolt onto my tool so I could thread my slide hammer onto the tool worked a treat 10 or so good hits then beer then one good hit and what ya know pop off she comes.
The woodruff key was located in the correct place and the flywheel was installed correct.
I will put it back together and start kicking again.
