F2 Carb Cleaning

(1/3) > >>

Terry in Australia:
Okay, let it be known by all men that I, Terry, F2 builder extraordinaire and unemployed porn star, have posted the first technical question in the new SOHC4 site!

OK, so I'm pulling my 1977 F2 carbs apart tomorrow, apparently my #4 cylinder pilot jet is blocked, as the bike won't idle on all four cylinders, but as soon as I give it some gas, it runs fine on #4. When I bought the bike in a hellish state it was the same, but I put this down to the zero compression in that cylinder due to a PO leaving out one of the piston circlips in that cylinder, allowing the wrist pin to wander up and down the cylinder, wearing a .5mm channel.  I've replaced the cylinders as part of the resto, but still haven't gotten it to idle on #4 yet? ???

Anyway, there's been a lot of sitting since the rebuild a year ago, and the bike has barely turned a wheel in that time. I originally cleaned the carbs out with some disassembly, but I couldn't remove the pilot jets, (pressed in) Does anyone know how/if i can safely remove them and reinstall them after I've done some serious cleaning? Any other pointers of note from the collective genius that this site comprises? Thanks Guys, in advance! Cheers, Terry. :-*

Chris in Ramsey:
Terry, I sure hope that the pilot jets can  be removed and re-installed, as that's what I've done on my F2 carbs! Grip the jets near the base with a pliers(NO SLIPPING ALLOWED) and twist as you pull straight out. You've probably received similar instructions from the directors of porn movies you starred in.
  After cleaning, the jets can be tapped back in, being sure that they seat all the way(the jets are slightly shouldered) This does work OK, it's also the standerd procedure on late-model 550 carbs. Good luck!

I have had luck with old Guitar strings, spray cleaner and high prerssure air cleaning them out. While I have heard others pull them out I don;t have the stones to do it. If the clog is from Vegemite you may all well give up and sell the Bike ;D.

Terry, the pilot jets on my F2 carbs have been pulled out and replaced by the PO.  He also put in 115 mains.  After I put in 105's when I rebuilt the carbs, the bike wouldn't run for sh*t.  I Put the 115's back & it runs much better.  I did get some old guitar strings from my neighbor next door (he used to play background music for porn movies, perhaps you've met) and used them to clean out the pilots.

Terry in Australia:
G'Day John, how are you mate? Yeah, I probably know your neighbour, and maybe his wife and her sister too! (Black Betty?) Ha ha, now as to who's F2 is the prettiest, well, yours can be the most beautiful in Birmingham, and mine is definately the sharpest in Mill Park, he he! Have a good one mate, I'll try those bigger jets while I've got the carbs apart, I've almost finished painting Tim's car, so I'll be able to play with the bike again tomorrow! Cheers, Terry.
