Bender Quad setup.

Pulled carbs off tonight and notice oil on the boost bottle on brake side and were boost bootle pushes on to the intake oil also, all three other's are dry any ideas? Also Jan 5th and 50 degrees its sucks..........
 

Oil is on outside of the bottle?
Is there oil where the head meets the jug?
Head gasget?
Is the air box full of oil/gas to?
 
Thanks everyone for the help.... Finally got snow in Wis. took vmax out seems a lot better. Plugs are nice tan color, only thing both cyls on clutch side seem hotter. No oil residue on the metal part of the plug compared to other two cyls. real clean looking and dry looking. End results are I bumped the pilots to #50, air screws two turns and mains to 145. Did not touch the needles. What are symptons if the cranks are twisted?
 
It sounds like your crank has spun. Just search (spun crank) and you should be able to find all the information you need from previous posts.
 
Talked to Pat Hauck today gave me a couple things to try and one was to drop down one notch on the carb needles. Got them tore down looking in the shop manual not very helpful anyone with step by step instructions.
