Another bad Kreem job

[JMR]

For the cost of the Pringel vacuum valve, you could save some money and just buy a brand new oem Yamaha 84/85 petcock from RPM (safety wired) and be good to go for another 30 years.

Hey Pat....we are talking fuel parts....not artificial potato chips.  If I remember correctly I was having clearance problems with the OEM petcock and aftermarket carbs forcing me to install the lower profile set up.

Hey Mike, no worries....FYI here's your post from back in 2011....yep, you had some FCR clearance issues:

I installed a Pingel adaptor plate ( not sure of part#)with a 90 degree fitting (part#229-8-6). I use Pingel's inline vacuum valve (part# 9050-AV) with the vacuum hose running off of #3 carb manifold. Very simple and has no problem keeping up with 39 FCR's.

Need I remind folks, back in the old days we needed a plan on what to do when our vacuum petcocks took a dump.
1) We did not have the luxury of RPM with an inventory of $126 oem petcocks. IIRC the cheapest was ~$220 if you could get them from Japan and 2) nobody had a rebuild kit.  
In that case, the Pingel vacuum valve was a solution to a malfunctioning oem vacuum petcock.

RPM has changed all that...IMHO.

Pat, what did you do for work before you retired?

You need to know what you're talking about, and in this case, because you don't have a gravity fed FJ, you don't know what you are talking about. You have a fuel pump FJ.

You do realize that the petcock and fuel lines and float needle seats are larger on a gravity fed system...correct? They are designed that way because they need to be that size...the gravity system does not have the benefit of a fuel pump pushing the fuel to the carbs, like on your bike.

  : You not only got me Pat, but with repartee like that, left me nowhere to go. How embarrassing not knowing how gravity works at my age. You say I have a fuel pump model, should I ever need to find it, where is it located?

Here you go Noel, I've circled my fuel pump in the photo - it sits behind the right side panel under the tank on my 89 3CV

[Pat Conlon]

Glad to help Noel. Even us old guys can learn something new....but you gotta be willing.

Back to the bad kreem job...

A little update. After spending a week in the electrolysis solution, it is now time for the paint stripper. The bad kreem job became even more evident after the electrolysis rust removal. Once the bubbled up portioned of the sealer were removed the valleys in each side of the tanks were found to be completely filled with tank sealer. This might have been a great thought, but no.

Here are a few photos. The allen wrench is about eaten completely away from the electrolysis.

Here are many of the big chunks I was able to dig out of the side valleys of the tank before starting with the stripper yesterday.

It is soaking in stripper right now to continued to soften the tank sealer down in the valleys. I had one run yesterday and got some more out. Going to let it soak for a couple of days all sealed up with the sealer inside. I rotate the tank a couple of times a day to coat the whole inside to ensure I get all of the old sealer out.

So after electrolysis, the tank looked rust free on the inside?
Are you using methyl chloride paint remover?

Yes and no.  Where the coating was gone,  the tank looks great.  But under what I am digging out is major rust.

Once I get all the coating out,  then back to electrolysis to get the remaining rust addressed.

I'm using jasco paint stripper from the hardware store,  nothing special.

As I mentioned, my take (aka my opinion) is........ appears too small in diameter for a gravity fed system feeding 4 carbs and a thirsty engine.

Hey Pat, I'm a bit slow on the uptake here but I just had a thought. If knowledge is limited to the bike one currently owns, as you say above, how come you know about fuel pump bikes and fuel cut-off solenoid fitted bikes?

As I mentioned, my take (aka my opinion) is that the solenoid in the picture may be fine for a fuel pump system, but it appears too small in diameter for a gravity fed system feeding 4 carbs and a thirsty engine.
The solenoid idea might have merit, just not that size on a '84-87 gravity fed FJ.

Hey Pat, I just had another thought. If I was recommending something, say a battery, a tyre, a chain OR a fuel cut-off solenoid etc, do you really think that if an explicit written instruction to buy the appropriate size, shape, length whatever, to suit their particular bike was needed, should they even be doing their own work? I think not.

BTW, I didn't use those tails in the photo, the looked a bit small and were smaller than the solenoid body.

[Pat Conlon]

... how come you know about fuel pump bikes and fuel cut-off solenoid fitted bikes?

I've owned a '92 for 10 years. Noel, let's take this to PM.

Let Randy's thread get back on track.

I thought something a little more contrite from you would be appropriate. Anyway, you've pulled the pin now.
