hmm to check if timing is correct, you should mark on the cd a sector same as on flywheel, not an arrow... correct me if i'm wrong... is the arrow you marked in the middle of the sector on flywheel?

I have tested my TCI on another xt and it starts without problem.

Now i am really confused. I've got spark, I've got gas, timing is ok... still doesn't starts.

If i remove the airbox i get small explosion in the intake, but with the airbox on i don't hear it at all.

the arrow is set in the middle of the flywheel mark |-|

Valves/valve clearances O.K?

ok..

Try checking if its the carb... Spray some "powerstart" or similar highly flamable spray into the airbox while cranking it over. If that doesnt work and you're SURE the spark is good then it can ONLY be compression. Maybe you've broken a piston ring or headgasket..

Have you tried a new spark plug? Sometimes the spark looks good but breaks down under compression. Contaminated fuel? Drain and try fresh.

I have checked the compression and it's 11.

Valve clearance is ok.

I have measured the pick-up coil and it's 237 ohm and in the manual it's between 184 ~ 276 ohm.

I will buy a powerstarter spray and try it.

Here are pictures with distribution on, am I wrong?

11 in comp seems high if its a stock bike. I believe theyre around 8-9:1 from stock.

Did you meassure it in psi or such? I've got a factory workshop manual vere the "limits" probably are meansioned.

11 kg/cm2 wich would be 156 psi as in manual.

Which is very healthy compression.

Gotta be fueling then ! Get the powerstart in there asap.

After pulling the bike for a while with the car :laugh: the bike started. For about 2 minutes only in high rpm. The dead again. Went home checked the fuel level and spark... and no spark. I bought a new ignition coil (even the values are like in the book) and now the bike starts but it has erratic idle and misfire on intake alot and if i take it in high rpm bigger misfire occurs.
Now i am thinking if not the pick-up coil is faulty even if the values are ok according to the manual.

have you checked the carb rubbers?...mine looked ok but when taken apart they were badly cracked and letting in air which made it hard to start and run very badly..

now i have taken apart everything in the carb, is OK... after i rechecked everything I found the problem... spark plug gap too small... set to 0.9mm and now everything is OK.

Thanks to all.

Conclusion: Always test your ignition coil directly on battery... it is the best way to test it.
