99 Super X #1145 Being Semi-restored

[AZSUPERX]

I'm going to order a new pump, regulator and filter Monday. I have been scewing around all week with this "cross pump" with no luck.

[AZSUPERX]

I installed the new pump and regulator and it still acts the same as it did with the "cross pump". It runs like crap and won't come off idle without feathering the throttle and it still won't run right tho. Any ideas?

[AZSUPERX]

Is there any way to check codes without a scanner?

[wytfut]

the operating system is OBD1.... but I don't know if the codes would translate.... my guess would be yes....

with it still missing.... my guess would be a plugged or partial plugged injector(s).
How old was the original fuel when you got it? .... I've fought the lasts 2 X's in my shop due to old fuel .... Injectors on one, and fuel pump on the other. ...

got anymore symptoms.... please send them here. I'm willing to help....

I am thinking injectors as well since it ran great up until the pump locked up. I ran fuel system cleaner through the tank and that probably cuased the break up of trash in side the tank.The fuel was about 5 years old. I drained what I thought was all the fuel but there was still some in the tank as well as the original fuel strainer came apart and thats what locked up the original pump. I see two different part numbers for injectors, are they different? I have my parts guy tracking down both numbers of the Walbro injectors, or is there a good place to get them? Thanks for the help I'm dieing to ride again.

what you've all said .... makes sense to me....  .... got a triumph dealer close by..... they have our injectors too....
Have to get Jamie involved on the numbers, as I don't know the difference..... I'm betting Marty would know via phone call....

Old fuel these days is nasty. Especially ethanol .....   The last one, the fuel smelled like it was 50 years old, and looked it, whereas in reality it was just barely a year. 

With information I got from Jamie concerning ethanol.... I try at all accounts to avoid that fuel.  Especially on long sits....

[AZSUPERX]

I talked to Jamie today and I'm going to try to get my injetors cleaned at a local place if they can't/won't  I will order new ones!

[wytfut]

and Jamie/Marty have some used injectors that have been cleaned and recalibrated for less money...

[AZSUPERX]

Yeah I just hate buying something used unless I have no option. I checked the codes today and only showed a fuel pump code shorted to ground...most likely when the old pump locked up. I cleared the code and ran it for a few minutes to see if the code would return and it didn't. I pulled the injectors and going to take them in tomorrow to have them cleaned and checked. Wish me luck!

[wytfut]

good for you

[AZSUPERX]

Today I had my injectors cleaned and tested. One was flowing at 37 CFM and the other at 58, now they are both at 67 CFM and the bike runs great! Cost me 24 bucks for the work and new o-rings!

[wytfut]

great!! 

[AZSUPERX]

Thanks for all the advice! Time to ride here avrages are 70-80 degrees during the day!!

I took the bike for a ride yesterday and made it about 50 miles before it started having issues. Today I pulled the injectors and cleaned them both and they were full of trash again. I installed a in-line fuel filter on the frame rail under the tank with all new fuel line and rode another 60 miles with no issues. Looking in the tank I see no trash but hopefully the filter will catch the trash. Since the filter is only 4 bucks I'll just keep changing it once a month.

A few thoughts:

Did you install a new filter with the new pump, other than the in-line filter you installed externally?  The pumps sold by both Jamie and Marty and John Jones have a "sock" style filter that goes in the tank with the pump in place of the little metal screen on the original.

Whatever trash you're getting in the in-line filter is coming from the tank.  If you didn't put a new filter in the tank with the new pump, that trash is going through the pump and regulator first, then out.

If the issues many have had with these bikes is any indication, it's possible the factory liner is starting to flake off inside the tank.  I found my 2016 in a dealer that let it sit on a shelf for 10 years with the original gallon of gas in it.  The tank liner had failed.  The dealer then flushed the tank for me and the inside rusted.  I eventually shipped the tank to Jamie and Marty for their vendor to clean and re-line.
