My current settings during the video were Tors screw: all the way screwed in. Air screw: 1 turn out. Im running a 290 main pilot. I have cleaned the carb and adjusted the floats. Those current setting were bogging quite a bit once it was warmed up. It died at the last second due to bogging down. All info helps, Thanks!

Oh and it does start up easily, the choke just wasnt staying out at the beginning of the vid

Seems like an Air leak to me , Have you Done a Leak Down Test to check Gaskets and crank seals ?

 

[cap9709]

Yep, it leaked just a tad bit more than what people were saying it should

 

[Triplecrown421]

sounds fine for a cold start.

remember the tors screw is your idle set, and the screw on the carb is your air mixture, For idle.

You will want to seal it up if you want your motor to last !

 

[cap9709]

Yep i know that, it seemed like it was smoking quite a bit. Im not as concerned about the smoke yet though. I think the first thing i should try and tackle is the idle because if i cant get it to idle, i cant fine tune any of this other stuff?

 

[cap9709]

Yea im afraid thats what i might have to do

 

[blasterBruce]

you need to fix the air leak first , the air leak is why your idle is not right , and if you have an air leak you will never be able to jet it properly !

Ditto, Ditto.


When was the last time the crank seals have been replaced ?

Not sure, I bought it about a month ago. My dad is coming over in a min. I think were gona talk it over and go from there. I'll probably end up doing another leakdown test and try and find this last leak

 

[cap9709]

My dads going to come over and well tlk it over. I'm probably going to end up doing another leak down test and try to find this little rascal!

 

[cap9709]

Not sure, just got the bike a month ago I'm gona do a leak down in the next 30 min, ill let u guys know what happens. thanks!

 

[cap9709]

Just finished the leakdown. Great news! It'll hold 6 psi all day long! Not really but it hasn't budged in the last 5 min. I was having issues wit my tester.

 

[blasterBruce]

When you do the test , make it at 7 Psi and if it holds for more than 10-15 mins your good

 

[cap9709]

I did it for a lil over 10 so I'm good

 

[blasterBruce]

Also , Another reason it might have been a hard start , I did not see the fenders on with the air box and intake boot attached

 

[cap9709]

Would you recommend they be on? And if so just out of curiosity what does that do other than make sure clean air gets to the engine

 

[blasterBruce]

I will not run a blaster motor without the intake boot attached ! , If your not using it, It is allowing allot more air into the motor than the Intake boot and filter setup , So Your stock idle settings will be different when you have the boot and Filter attached

That long runner "Intake boot" will make a HUGE difference in tuning that carb!!! All this "stuff" is on there for a reason.Put the fender/booty assembly on the bike,make sure carb is clean,air filter is clean,and the boot is hooked up,then go from there...
MAKE SURE THE CARB IS CLEAN!...Don't just spray off the outside with carb cleaner....Dissassemble it and CLEAN it! Make sure all the jets aren't plugged.
