The TPS should be centrelined at 1250, and then rise at around 1450-1500 (ish)
Might give the engine flush a go - would any brand of this work or is there a suggested brand for motorcycles?[/QUOTE]
The Liqui Moly one is apparently very good. Its not something that you need to do every time, just maybe every 5th time.... its probably more important if you only do short runs on it, like less than 20km on a regular basis. Getting plenty of heat (which ha ha might not be your issue) helps to evaporate any condensated water that gets into the oil on cool down, which along with shitty fuel quality and blow-by contamination, can cause the oil to get sludgey.....
Just follow the instructions, and, once it has drained, i always just pop the plug back in finger tight, and the filler plug, ( i also drain the old filter and screw it back on) and start the engine and hold the clutch in and that flicks the old oil and cleaner away.... stop the engine and then undo the drain plug again.... you will get about 100-150ml more out of the engine.....
Once its all stopped dribbling, i drop about 100ml of clean oil in with the plug out and that removes the last of the old crap....
Yeah, i know, it sounds anal....but, i have over 280k on my original engine now....[/QUOTE]
You start and run your engine W/O oil in it!?!?
Also, if you are trying to get every bit of oil out of it, I would also recommend draining oil out of the pump pick up cavity.
