TOPIC:

thank you everyone for the help.

I should also add that every time this occurs it's during during decel. so if the slide is closed no matter the rpm at your utilizing the pilot circuit of the carb correct?

if so it might be somewhat safe to say my problem is fueling with the slide closed

The main and needle will actually have an effect on the piolet at low throttle position .

clip on top notch of needle is best. throttle response is perfect. but after 15 miles or so it dies out still won't restart


while its trying to restart.. it'll fire for a quick second then continue not starting

and also the starter makes this horrid noise. def gears grinding. doesn't really do it when it cold, but when warm it does. and if (while cold) you give it throttle while starting it makes the clunking sound.

something in the starter? still doesn't solve why I'm dying out on decel 10 miles into a ride


edit: I just went to go start again where I left it in a parking spot, maybe half hour later. fired up idled for about 20 seconds went to pull out of spot gave it slightest throttle then died and won't restart. seems flooded

Sounds like you did not let it warm up before trying to ride it. 20 seconds isn't enough time for these bikes to come up to operating temperature. Ed

it's 90 outside today and I rode 20+ miles within prior half hour to this happening

duh moment, just seen your compression test post. not sure where else to go, from what I have seen it is super rich. what piolet do you have?

You're right, that certainly would have warmed it up to normal operating temperature. Ed

30 pilot top clip of needle. I tried a 27.5 and it was hunting around to return to idle


the alum manifold might have something to do with it. it's hot after shutdown, and so is carb. kinda. but I can see fuel in the fuel filter building up, almost as if there's an air pocket in the carb and fuel won't flow into it. I don't know

I'm going to try soaking timing advancer down with pb

new pretty decisive update:

when motor is full warm and won't start I get 85-90 psi in each cyl. I comp tested it a few days ago not ice cold but not warmed up and got 130+.


when I adjusted the valves recently I HAD to of made them too close, right? comp usually goes up as shit expands, it has to be a valve sticking open right?

It sounds like that could be the problem. I would increase the gap a little and give it a test run to see if the problem goes away. Ed

Like I posted above, check your valve lash.
Your intake valve is probably to tight.


.

this is killing me.


I backed all the valves out almost a full turn. could def hear them ticking when I was riding. didn't break down on me while I was out, but I specifically let it idle for a few mins then let sit for 10-15. it started the first time, thought all was well, let it idle again for 5 min shut down for 15. then nothing.

a full turn on a valve adjustment is more than enough for expanding metal right?

also, the 11th hour 2-1 alum manifold gets very hot

edit: compression when warm is even on both sides gauge saying somewhere near 120. all gauges read different. I don't think compression is my problem

as soon as the aluminum manifold gets heat soaked from sitting it won't start. plugs are dark black, but for the most part not burning any more oil. bike sat for years I'm guessing
