I just picked up a batteryless efi ps 580 from my contractor for my girlfriend as a trail/cabin sled.
Real quick history:
The sleds in pretty good shape, less than 2K miles, engine has good compression... pistons and cylinders look good. Get's good spark.
I was told that the only problem it has is that the pinch welds on the pipe are blown out... which is no big deal. It's blown out along the seam for about 12 inches, and then has two good size cracks running across the pipe where it tapers back to the can. I'll have it welded up today.
However, after siphoning out the old gas, and replacing it with new gas, and putting a little engine assembly oil in the cylinders and priming it a few times with the plugs out, popped the plugs back in and got it started in two pulls.
Idle sounds like a typical 2 stroke, I clamped the blown out pipe just to make sure it ran. There was some leakage, but didn't seem to be any real issues.... Until! I gave the sled some gas. If I blip the throttle it seems a bit boggy, but not bad... but get the revs over 5000 rpm and they don't want to come back down. It doesn't race, doesn't modulate, just holds the rpms you bring it up to. The throttle body's are opening and closing, the throttle cable isn't sticking.
Obviously it's going to need some work. But how much will dictate whether or not I keep the sled. I've heard they run great when they run, and I'm more familiar with efi than with carbs. After some research it looks like the ecu is throwing a code 1 flash, two seconds, 1 flash. Does this mean that the TPS is bad? or that there is just a funky condition that may be caused by a lean condition due to the hole in the pipe? And does the TPS just stop working or does it come out of adjustment?
My plan of action will be (if I'm not walking into a $500 fix it project): Weld exhaust, Pull motor, clean up the engine bay, clean up and reseal all grounds and all electrical connections, replace throttle body couplers/hoses, and then a TPS/throttle body setup.
Should that do it? Will I have a reliable running sled that won't run off into the woods and mangle my baby's mother (a bit morbid, but worst case scenario), or is this sled that I'll use 3 or 4 times a year going to become a money pit (more so than a normal sled).
One more question, I have seen a lot of battery efi TPS/throttle body setups for sale used, BUT, are the battery efi sled TPS's compatible with the batteryless efi TPS's?
Really appreciate your knowledge and help here! I ride a suzuki sv1000 and know how great their engines can be, and I'd love to keep a suzuki powered sled in the garage to keep the crotch rocket company next to the Yami ATV and Sled
