Gas on the spark Plug
« on: November 23, 2011, 05:40:32 PM »
Today i gapped and put in the new plugs, the old ones looked ok but #1 smelled like gas and #2 smelled like oil, i could even see the oil on the threads but not the end of the plug #3 & 4 looked real good so should i be worried about 1&2 ?  :-\

there was no oil in the plug wells but maybe #2 well gasket is just seeping a little? i went for a 5 mile test ride and she runs great.

It does not spound like anything serious on its own.
If you do not have a leaking petrol tap, and a sticky float valve - you should be Ok.
A little oil on an older engine could well be a leaky seal rather than anything more serious - as long as your oil level is not falling too quick!
If she runs Ok with no hesitation or noises - then keep an eye on this issue - but ride when the weather allows! :)

New petcock from Murph September of last year, i just checked it and its not leaking' however i think i do have a float that sticks once and a while so i will just have to keep an eye on the petcock and make sure there is no gas on the ground before i start it, What deference a new set of plugs makes, she has always been a little hard to start in morning cold but the new plugs make it start a little quicker.

Thanks for you input vinny i appreciate it.

No worries mate - glad to help out.
Parking your bike on the centre stand does seem to avoid some of the sticcky float vakve issue - but not entirely.
Also watch your oil level - if it rises - be careful - it may be water - not great but it could be gas - a lot worse.

 Remove the oil cap, and sniff test the crankcase for Gas.

I just changed the oil & filter two week ago, it didn't smell like gas and looked pretty good for 3,000 mile oil, the oil level is just above half glass right where i put it and it has always stayed there never needing anymore til the next oil change, i will just have to keep an eye on it and maybe park it on the centerstand more often, its probably time for some seafoam or iso-heet, its been awhile.

Might be a good Idea to drain the float bowls into a clean clear container, to see whats there. Then once drained, with the drains open, place the petcock to Prime. That will flush the float needles a bit. Might rinse off a loose piece, might not. But can't hurt. If stuff is in the bowls, well better go through the fuel system. Clean the tank, Petcock, Carbs, install a in-line filter for a gravity system, and well consider the overflow tubes.
