Hey BigNasty, when your dealing with mud traditional tuning gets thrown out of the window! There are soooo many variables then including which frankly makes setting the iniial tune for the heat a crap shoot. I tend to richen the engine a bit asuming that picking up all of the extra weight (whichin you case you mentioned was 3 pounds!!!) is going to increase the load on the engine making it run hotter. But then you have to worry about the filter getting wet which makes the engine run rich . So don't richen the engine and you can be way too lean, richen the engine and you can start out good but if the filter gets wet then your way, way too rich....it's realy the luck of the draw in these type of situations. What I will say is don't be too concerned about what happened in those type of situations. Clean the engine up, change the clutch bearings as there is a good chance that they are bound up and try running it in normal, dry conditions and see what happens. Regarding the plugs Kortz runs either our TLP5BT or TLP6B5 (#5 or #6 buggy turbo plug) both of which should he available from A-main. Give them a shot I think that you are going to find them much more durable than OS or OD plugs!

Ron
