troubles starting after full build

[slimguy379]

If I take off my air filters I should see a chunk of the slide gone right? Or am I wrong?

[slimguy379]

And the pilot doesn't have too much to do with the start up but I'm also having an issue maintaining a constant run so its either starving or being drown I think its being drown so hence going down a jet size

[trickedcarbine]

Your pilot has everything to do with start up and with mikuni carbs the best airscrew setting should be about half to one and a half turns out. Keihins a are usually 3/4 a turn to 3 turns out. Get that set right and it should also stay running.

 

And yes the back bottom side of the slide should have a half oval shape missing.

 

Also, you mention in an earlier post that there are stock pilots in the carbs. Are there any mods done to bike?

Yea +20 t5s port polished advance time but it runs stock time now to narrow down issues. Damn I was hoping u would say my slides are in wrong lol

Try a 27.5 pilot and 1/2 a turn out on the air screw. Fine tune the screw from there. Also watch a you tube video on carb syncing. It will help you make sure they are set up right as far as slide height, idle, opening at the same time.

No tors?

 

If not, unscrew the idle screws until the slides are all the way bottomed out. Then screw the idle screws in until you see the slides shake or move. Do not lift the slides yet. Screw each screw in 3.5-4 full rotations. Turn the air screw to 1 full turn out.

 

It should idle with these settings. Once it idles fine, adjust the cables to allow the slides to move at the same time as well as open fully.

 

If it won't start with these setting, take a bottle cap with gas from your tank and dump into the throat of the carbs. This should get it enough fuel to start.

And 27.5 pilots should be where you start with the t5's. my bike stumbled on 27.5 and had to bump to 30's with cpi's.

 

You can also note that if you get it to start and idle, turn the air screws in all the way after it starts to see if it dies. If it does then your pretty dead on with the pilot size. You adjust it to .5-1.5 turns out and listen to the idle raise or lower.

 

If you turn the screws in all the way and it doesn't die, bump up to the next higher jet.

What donut boy said, kinda. Set the idle speed until you can get it to idle by itself. Then turn the screws in or out evenly, a little at a time while listening to the idle. You want to get the highest idle possible by adjusting the screws, but if it goes outside number of turns mentioned above change the pilot jet accordingly. You might have to tweak the idle screws once in a while if the idle gets too high while adjusting the mixture screws. Once you get the highest idle possible from adjusting the mixture screws, adjust the idle screws evenly to set the idle speed. Make changes slowly and evenly (1/4-1/2 turn at a time) giving the engine time to respond between adjustments.

Who the fuck is donut boy? Listen to what dick 5.0 says and merge the two comments together. 3.5-4.0 turns in on the idle screws should get you into a good idle range. Adjustment will have to made but you will be a lot closer than what you have now.

Pastrykiller not equivalent to donut boy? I misenterpret the name? Or are you a chic? My bad either way. And yes merge the comments. That's what I thought I said too. Didn't say you were wrong. Was just adding to the comments.
