Tune up Vintage Speedster

How do you get to the spark plugs when tuning up? I have dual carbs and for the life of me can not get to the plugs.

Just takes patience and the right socket and extension for a 3/8" drive ratchet.

I took the carbs off mine and found it easier to get at the plugs. The last thing you want to do is cross thread a plug when putting it back in.

Ed, I've found that putting the plug in the spark plug socket, then using the socket to start by hand works well. The space machined between the cooling fins for the plug and the socket work as a kind of guide.

If you have cleaned any carbon off of the plug threads and given them a light coating of anti-seize compound they usually hand start without any problem.

I torque the 12mmx3/4" plugs in 044 heads to 16.5 ft. lbs. which isn't too tight but keeps them from loosening up.

Greg,

For starting a Plub, you may consider placing a piece of rubber hose over the Insulator End and with the hose cut to a managable length, you can turn the Hose and the plug will generally "Start". Once Started you can utilize a Socket for tightening.

Good Luck,
