Trouble starting Roketa? - Page 3

Got my registration, insurance, and permit. It only took 3 hrs at the DMV and there was no one there. Went for a long ride this afternoon loved it. Bike is still idling high, I think it may be an air leak.

Great news! Have you tried turning the idle screw down?

Enduroadventure · 05-08-2012, 11:30 PM

Yes I tried to mess with it a little. My dad and uncle looked at it tonight and they both think it's an air leak on the rubber piece comnecring the carb to the barrel I'm gonna order a new one for 12 bucks and go from there. I don't want to create more issues buy continuous changing of the screw.

I have a question on tire pressure. I can't seem to google this answer. What should my tire pressure be about with street tires on the bike, is it different b/c they are not for dirt.

Weldangrind · 05-09-2012, 02:22 PM

What pressure are the tires rated for?

FastDoc · 05-09-2012, 02:53 PM

28F/32R is a good general ballpark I use if no other data is available.

MEDMUNDS · 05-09-2012, 04:31 PM

motorcycle tires i use on my bikes are between 32 or 36psi but i run my tires 5 psi under the the psi rating

Enduroadventure · 05-09-2012, 05:16 PM

See that's what I thought the tires say 40psi on them. Does that sound high to anyone

FastDoc · 05-09-2012, 05:37 PM

That's the maximum pressure which will likely be much higher than the correct running pressure.

Does anyone have a diagram of the pz30 carb. I have taken it off the bike again and have it apart on the workbench. I would like to know a little more about it.

Weldangrind · 05-09-2012, 10:05 PM

I don't have a diagram, but I have a PZ30 here. What would you like to know?

Enduroadventure · 05-09-2012, 10:10 PM

Is the screw with the spring on it, on the otherside of the carb from the choke the idle screw? Featured in the first carb picture on page 1.

Weldangrind · 05-09-2012, 10:20 PM

Definitely. If you remove the slider, you'll see how it has a ramp at the bottom that the idle screw engages with. Basically, turning that screw in is the same as holding the throttle open a little.

Enduroadventure · 05-09-2012, 11:38 PM

Got it. It idles and runs better. Still a little funky, it surges, it idles fine for a moment and then surges up and when I adjust the screw back down it idles too slow and dies. I cannot seem to find a perfect setting.

Blame it on the PZ30. I've had waaay better luck with the 30mm Mikuni, and they're less than $40, including shipping.
