Any help? Just came back after a rather long(ish) cruz with the new oil pump. The bike sounds totally difrent between premix vs. autolube especially at idle. Anyway, I did a plug chop and found the rear cyl. to be in the mark but the front was brighter than tan with heat effects showing all the way down the band onto the sparkplug face. Oooo... too lean I suppose. Its weird since the left pipe (front cyl) would smoke way more than the right pipe (rear cyl.) but the front shows that its running hotter than the rear cyl.

When I did the chop I could hardly touch the rear plug as it came out the spanner but the front was much cooler. Maybe its just cuz the rear isnt in a direct flow of air, but somethings up. I'll have to re-jet everything (MJ) since the setup was optimised for premix.

Any help on the above pump question?
