hi
i am new to this list and it looks like there is some mach z peps here.
i just burnt down my 780 so i am trying to redo it again after 150 mi's OUCH yep it hurts and still hurts
i dont know what base gasket to try now the sealer says there is 3 3mm 4 m 6 mm and they also said i can run a 3 mm and a 4 mm to make 7 mm
so i am stumped i dont know why it burnt down because it was fouling plugs earler in the day but i was going over 100 mph when it burnt down you machz lovers i love this sled but it is getting costly i am going to get a set of egt gauges before i run it again
one more thing last year it had crank seals done what should i do ???
thanks john mc

What kind of oil are you using? I was told to only use synthetic oil in the 780. Also what plug and gap, was it too hot? I just got mine so I want to know what to do to make things last. I was told to use 92 octain fuel it helps it run cooler. What type of gauge are you getting and what does it do? Good Luck with every thing...

i was running 92 oct. fuel and castrol sent. oil stock ngk plugs br9es dont run it over 100 mph and it prob will last .everyone i talk to tell me the same thing.but you will go through alot of plugs in the mach z 780 i am going to get exhaust gas temp . gauges and put them in the exhaust pipes if it gets to hot i will have to back off the gas. 1300 deg. is melt down so i was told 1000 to 1200 deg. is ok. this will help me jet the carb too.when i fowl a plug i wont have to look for it also i just look at the gauge that is cold.
i might get a dial a jet also for on the fly jet adj.ment
