Having a problem with my 1998 Suzuki 200HP EFI. 2-stroke, as those on the Solent Cruise a couple of weeks ago will know. Itís been fine every time until then.
It starts first turn of the key every time from Cold, and ticks over like a watch.
Then when its warm, the tick over sometimes gets a bit lumpy, and if stopped is sometimes difficult to start again. When itís running at anything above tick-over, its fine.
On the cruise we went over the loom several times to find any loose connections, and it suddenly started and ran sweetly, then also started fine later in the day after lunch, and after stopping for fuel. Whilst searching for the fault there was no spark at the plugs, but fuel was getting through, so Iím presuming its electrical.
Iíve been over the loom, cleaned up all the connectors but didnít really find anything wrong.
If it had some form of choke mechanism Iíd blame that, but of course itís all done by the EFI. I will however remove the temperature sender from the block to check for corrosion in the thread before using it again, as an old injected motorcycle of mine was very sensitive to that.
Before I go out again for testing and get stuck, does anyone know of any electrical items that are particularly sensitive to heat/weak generally on these engines, or does anyone have any ideas about anything not covered above.
