I've checked out the previous posts and most people have problems with elderly XJ's that wont rev. Mine is fine, with a definate kick at 7000 rev/min however, at low engine speeds, say below 2500, sometimes the engine seems to bog down and doesnt like pulling away from junctions.
I get around this by riding quickly, but really want to get it sorted. I have not had the bike long and the previous owner "Cleaned and balanced" the carbs. This from somebody who bought a new seat cover rather than swingarm needle rollers.
Could it be as simple as poor vacuum/air leaks? Where's the best place to start?
EDIT: I found tonight that a previous owner has junked the air filter in favour of a pair of ladies tights (Pantyhose).
Is this enough to scr*w the low speed performance???!!!
Thank you,
