I thought this may be of interest to the Gen 1 owners, specifically the '99 and '00 model owners.
Today I had some spare time after a 380km ride and thought, 'today's the day I check my fuel system compononents that I've never looked at in the 4 years I've had the ol' girl.
I've been meaning to check it over for awhile now, but today during my ride I had a lean surge at cruise speeds of between 120kmh and 140kmh. Not all the time, but more often than I was happy with. The last time I had a surging issue I found the fuel pump sleeve screen blocked with gunk, cleaned it and all back to normal.
So this time I thought I'd start at the fuel tap and condition of the fuel tank (original tank) and work my way forward to the injectors, checking everything thoroughly and sorting any issues that are there.
I want to also check the spray pattern of the injectors, using a clean white sheet of A4 paper and firing the injector at it from a couple of inches away. I do this at work with the Suzuki LT500 Quads and it works well to ascertain bad injector spray patterns, fixed a few poor running issues and the boss was impressed.
So here's some pics . . .
I know y'all like pics lol . . .
The fuel tap mesh screen is pretty dirty, what do you guys think?
Below . . this is with the screen help up in front of a flouro lamp in the garage to give you a better view of the inside of the mesh screen.
Here's the fuel sender rheostat, quite clean, but it should be, it gets fresh fuel every weekend!
The fuel tank inside has no rust at all, looks really clean!
Looks like someone's made this rubber gasket, if that's OEM, someone drank to much Saki and went to work hungover lol
Here's a few shots of my plugs, they look quite lean in my opinion, I would like to see more colour in them than that.
I disconnected my Power Commander a couple of weeks ago to see what difference there would be,I'd had a bit of rough running occasionally so I adjusted the fuelling with our Teka module at my workshop, made it 10% richer at 5-10% throttle opening, and 5% on all other throttle positions thru the scale up to 100% WOT.
We use the Teka to enhance the fuelling on Suzukis with a free flowing exhaust and Air Filter fitted.
I will recheck the plug colour after the fuel system is gone thru, and any issues fixed.
