Won't Start

Pulled the carb body out of the dip. I let it soak for 22 hours.

I am still unable to remove the pilot screw...it is stripped pretty bad, guess I am screwed. Am I suppose to dip the starter plunger? If so, how do I remove what looks to be a rubber piece at the end of the needle. Also, how do I remove the basket from the needle valve and seat? or is it okay to soak that with the basket on, just remove the o-ring?

I think the carb looks pretty good, never dipped before though. It appears to have a oxidation look to it, I assume that is normal..

The little filter did its job, so get another, probably $5. poke/blow that little hole in bowl bottom that feeds enrichment system tube, cuz its a good place for crud to hide.

Well I just dropped the carb body.

Nice productive holiday, worked on bike ALL day, felt productive.

- Tore down carb 1, except stuck pilot jet
- degreased carb 1
- dropped in carb dip.

Another question, after pulling the float seat, I noticed a BUNCH of muck, and crud in the cavity. I also noticed that the basket looks to be tore a little. Not sure if this is a big issue or not. I made sure to clean the cavity as best I good as well as the basket. I tried to take picture but focus is not working for some reason.

Will it be okay if I have a little tear in the basket filter type piece?

Thanks. I may pick up some pbblaster when I got get the carb dip.

You may want to dip the carb in Berrymans for a bit to see if that'll help get that jet unstuck. Also, I've had MUCH better luck with PB Blaster compared to WD40.

Yeah, they probably put new float bowl gasket on it to cover up the crime scene- that bowl is ugly and its gunk has likely spread. You likely will have to grind a screwdriver to fit perfectly, the blade needs to go 95% across pilot jet head, so grind the sides down to suit- it's rare to have a screwdriver just happen to fit well.

Float bowl gasket

Well I am deep into the tear down of carb 1.

I have never done a tear down before, but I think the carb looks pretty good thus far. The float bowl gasket was barely dirty, someone may have checked the float bowls recently, the gasket looks almost brand new. The float bowl screws were easy to remove, much to my happiness as others were a straight PITA.

Bad news though..

Have a big problem though... I THINK I may have stripped the pilot jet. I removed the rubber plug, which is in good condition, loaded the slot with wd-40 and carb cleaner, and waited 2 minutes. Stuck in my crafstman screw driver and proceeded to turn, it slipped pretty bad two times. So I stopped peered in and it looks to be stripped a bit. UH OH. So I loaded it up again with wd-40 and am taking a break...

I will post pics later of the carb to the point I am now.

Starting the carb tear down process. Ran in to a snag with the carb rack screws, waiting to get my hammer drill back...

In the meantime, I am going to degrease the carbs. Any suggestions on a good grease removal agent?

Just grab them with 5 inch long vice-grip--it will break their 30 year old hold! Remember to keep carbs in individual containers.

Call them as they can look it up for sure. A lot of times they'll have stuff that won't show up on their site.

Anyone know a reliable website to buy some float bowl gaskets? I see some at the Z1 site but they don't specifically say for 81 650E.

Don't use a hammer drill on them use a hand Impact driver to break them loose, while you are waiting you could degrease them with pine sol cleaner works pretty good

If it's nicked, get a new one. Your present cable might be correct length if it was routed correctly (under tank, etc.). Shop around - OEM is worth paying a premium for apparently. My spare is a good used stock one.

Just pulled the airbox, it looks in good shape. The boots seem to be okay, I do not see any tears or anything, the rubber seems solid. Although one boot on the ridge were it slides into the box is smashed in, gonna be a pain to put back in the box. Another one looks almost like the carb melted it a bit, as I can see imprints of the clip in the rubber..

I may post pics later.
