G'Day All,

Been getting everything ready for the big ride.
The Flash has been sitting for 9 weeks waiting for wheel bearings brake linings new tube and time to assemble.
My first ride today was a little concerning! Started in the usual manner but blowing smoke from the right hand pipe eek. Smoke increased with revs
In the time it took to fasten my helmet and pull her off the centre stand I had fouled the right hand plug, a quick run up the road and all was well.

I went for a run of around an hour and a half working the engine on hills and varying the revs from idle through to near W.O.T (not quite but close).
Stopped for a coffee and ended up waiting for the rain to stop, total around an hour and a half. Restart no smoke...
I am going to do a compression test on Monday to see if there is a sizeable difference between left and right. Does this sound like rings or glazed bore or valve guides?
As per Musky's recommendation I adjusted my valves before the last ride and found them to be out by .005 for both exhaust and inlet. (too tight)

Sounds like your engine wetsumped during the 9 weeks layoff, drain the sump after the next long layoff and measure what comes out. Ride it more regular is easiest and most pleasurable fix  smile.

G'day Darren,
                  kommando might be right (welcome by the way). Did she blow any oil out the breather? Other than that how is she going? You'll have to give her a good 450 km round trip down here, that's less than 1 days ride on your 6 day ride. Sorry I'm not going to make it. Bike nearly fixed (doing battle with a new Indian front guard), I'm better. Got to babysit the GK's for 2 weeks.
Cheers

Wetsump... That would be a great outcome.
I usually (only left her that long twice before) drain the sump when the weather has stopped me riding for a while, this time I was in a hurry and simply checked the oil level and fired her up.
No smoke today, hopefully the compression test will show them both to be close to even.
Musky, I will try to make a run down your way before I go. I was told GK's are better than the originals because you can give them back after a few hours... two weeks sounds like a long time! wink
