Great video! I still am having problems with this 1979 Yamaha DT100F I have I can’t get it to run right. I’ve replaced just about everything in the carb including the float needle, seat, float, and replaced necessary jets to OEM and soaked the carb and sprayed it with carb cleaner and compressed air and it still doesn’t run right. I dont see any visible air leaks but they say to use brake parts cleaner or wd40 but you can’t test for air leaks if it doesn’t run right if at all and you can’t get it to run right if you have an air leak so a loop hole there…

I’ve also replaced every single gasket and rebuilt my top end and it has 120 psi compression at a recommended 105 compression so that’s not the issue. It has the tendency to flood which doesn’t sound right ive messed with every single thing on the carb and it either gets too much or nothing at all.

I’m really stuck on this one. Can anyone give me some advice? Thanks!

Just a heads up I don’t think that Cr85s have a timing mech and it’s just a bolt on as long as the woodruff key is aligned

[andrewanderson]

Would you be able to set up the timing when the engine is outside of the bike frame but fully rebuilt?

At 6:10 when you tightened the 1st screw I believe the stator slightly shifted on you that's why you were a hair off

[DADSGETNDOWN]

What year did they start to be able to do this stuff on ?

[MikeAsbury-tiyx]

No my cr250 is 2mm before TDC on the F mark even with dial indicator it's shows 2mm b-tdc

1999 250 Polaris 2 stroke ignition timing on base stator plate

[CrippyCream]

I’m having trouble timing my 05 ttr le. I line up the cam sprocket to the notch and the flywheel to the case mark but when I turn it over it never lines up. I’ve done it over but the timing doesn’t seem to line up. Idk what to do..

[luisgigothynasgutierrez]

I need help with the stop engine button where it connects in the left side my lil brother pull on it and all the wires are out

[harleyloco]

If the timing line on the flywheel is around 1 inch past the stator line. The woodruff key is perfect brand new oem crank. What would the issue be ? On a ktm 85 ?

In 400meter race ignetion timing on magneto coil plate witch marking want to set sir

Does advancing the timing help throttle response? On chainsaws it seems to help with that? This is comparing apples to oranges I know, but was just wondering!

hello, tell me?yz250 2t 2013 I set the ignition according to the manual, the marks match, but when working at speed, the ignition goes to later, but it should be earlier, I disconnect the connectors from the carburetor, the ignition does not change at speed

Anyone got a idea where I can buy a kit to time a husky wr125

[ejb]

Do you need the Kx at top dead center for the timing

[cinelli]

Does a yamaha it490 have a timing mark?
