Is that gonna be a problem, i mean obviously it will function but would an adjustable carb be better?
I have two 7-10s with fixies they go good man like yeah perhaps something left on the table but take a couple 3 swipes off the rakers and it'll clean up in the cut
Ok guys. After old mate before showed us his 805 with a accidental 2 piece rod I got scared a bit.
Have any of you had 1 go and heard it before it did and relized what it was before it let go?
I ask as I got the 800 out today and fired up. Fired up good tune still good. Gobs n gobs of compression like it will hang from the cord until your bored and arm sore. It came with its original bar its still pretty darn fresh.
It has a sound. I dunno hard to explain a sound but it has kinda like a rattle. I put it down to the clutch or something now the bar is still on it so clutch is indeed working rather than the drum spinning away happily.
Its a rattle and moastly at idle and it almost sounds like it could indeed be a rod knock and after looking at old mates disaster im freting about it.
Perhaps I'll try and video the sound
The gay thing at the moment is USPS have decided not to ship to NZ so bearings are not really a happing thing

Good to hear.
I think the biggest problem would be up and down movement in the bearings. The sp81 that I put together with the LRB piston is pretty loose as far as side to side but no up and down.
You could probably take the spark plug out a put a dowel on the piston and maybe feel if it has excess slop or a bad spot while rolling it over?
Flywheels come loose though and I'd definitely check it.
No problem, they generally run pretty strong.
That's not a bad idea I might have a go at that. I'm hoping its just my picky ears playing with me. Its going to be hard to roll over man alive do those rings have 1 heck of a seal. No decomp it's a man's saw to start
If your 800 will hang from the recoil then something is likely amiss as the residual compression is usually enough to push the piston down to the Q-port IME.

Ron can you elaborate on the Q port ?
The qport is definitely doing its job it bleeds it off no problem but once its past the Q it's very very sealed all the way to TDC
Its a small cut out in the exhaust port to bleed off compression
Q port exhaust on the right. Non Q port exhsust on the left.
Seems to start a whole bunch easier now

Makin' me drool...
Is that your picture or one of mine’s? If it is mine, I sold that NOS 850 cylinder for $20. Been kicking myself ever since.

Was a long couple years waiting for an 81. Grail saw for me
