Hi guy's,
I did a couple of compression check's just after I got the bike, both cold and partially warm, both cyl's running at about 130 psi, so I don't suspect much is wrong.
As I've mentioned there's nowt wrong with the performance once the tacho hit's about 8K right up to the red line, it's ok upto about 5500 rpm too, it's just the bit in between!!!
Which is is why I'm now wondering what else it can be, lean midrange???
I'm now thinking my problem has been twofold;
1, Cleaning the various connector's seem's to have cured the power drop off that I was experiencing after the bike had been run for over 1/2 to 3/4 hour, and in particular in the wet.
2, There is a distinct lack of oomph between 5500 - 8000ish rpm, which is why I'm now wondering if the bike is running lean between these points?
The bike does instantly take off at about 8 grand though
I've now got the (borrowed) pipes off power valves are correctly adjusted and "slide" freely on their shaft.
When I stop when the bike is running crap (actually doesn't run badly, just lack's performance) and blip the throttle the valves seem happy enough rocking, doin' their stuff.
At the moment I haven't a clue what's wrong......
HELP!!!
I take it the carb spec's I've given are correct for a stock bike.
Any more Idea's greatly recieved!!!
Thanx, Regard's Phil
