1978 gs1000e grey smoke coming ONLY from right exhaust

Just had another thought. Do you have the old plug caps with the ceramic resistors in them?? To check, pull off 1 or 4 and look inside and youll see the plug socket is slotted. Unscrew it and dump it into your hand and see if theres one in there. If so, remove all mof them and replace with a 1/8 diameter piece of copper or brass rod cut to the right lengths.

Note that 2 and 3 have a spring that goes into the cap first, then the resistor, and then the slotted socket thing. Those resistors fail and youll have a weak to no spark and thus very poor fuel ignition on the cylinders.

Damn ... thx for the thought !! Lol wheels are turning are they ? Haha I appreciate it ..
I removed all 4 plugs , cleaned em all , then putthe plugsfrom # 3&4 into 1 &2 .. switched em all around . Noticed my cap for #1 was cracked , luckily had some spares , cuzz I just replaced all thecaps on my 650 ..

I also checked all sparks after switching plugs .. all 4 have awsome blue spark !!

Do these old 78 gs 1000 e typically run hot ? Like my 83 650 would get hot ...this 1000 is HOT !!

Cracked plug caps can short to the block before the spark gets to the plug tip, but outside the bike of course the cap is far away from the metal and wont arch across. And yes they do run pretty hot..you need a few fans in front of the engine to keep it cool while you tinker.

Hey Chuck . In regards to heat I was referring to yesterday. I took a 1 1/2 hr ride in the country .. & after about an hr the engine is damn hot , no stopping what so ever doing approx 90 - 120 km/h id think the bike would be cooler with the wind blowing on it at those speeds .. as for the cracked plug cap , found that bugger the hard way !! Lol reached to pull cap off engine while running to check spark , the moment I touched it ... hahaha
I thought switching the plugs around and adjusting gaps helped with the smoking issue up till 20 min ago .. just rode into work and once you ride the bikefor an hr then get stuck Iin traffic . That right pipe still lets out a big puff of greyish smoke everytime you come to a stop !!

I took the petcock out 2 days ago and took it appart , gave the spring a slight pull , as well as the bent metal spacer ring . Just bent it a little more , then re assembled ... and I havent scene gas in the vacume line thus far since doing so ...
If I could also ask for a suggestion in regards to oil ?
I have done 2 oil changes on this bike in the last month , well within 2 days of changing the oil and filter the oil is black !! Im not running the best oil just castrol 10w-40 ..
Im wanting to do another oil change this weekend , any suggestions on a good oil ? Or possibly switch to synthetic ? The oil filters I have been using are just fram ...

If it wasn't turning black, it wouldn't be doing it's job. It's picking up all the dirt in your engine and keeping it in suspension just like a good detergent oil is supposed to do. You don't really need to change it again.
