dont aplogize. just dont expect me to pay for the online tutoring:). so moto, would you say idealy, given allowing chassis dimensions, would a vertical spark plug be better? im assuming the only time when an angled plug would be better/practical is if there were 2 plugs in 1 cylinder.

curiosity sometimes eats at me.

I would say straight and centered in the combustion chamber is best unless testing dictates otherwise on a particular engine.

NGK makes some shorty syle plugs that might clear the frame.  Be interesting if someone wanted to tinker with a coolhead having a custom dome with the sparkplug hole centered and straight if it made enough more hp to be a worthy mod.

I originally asked because in general center is best but I wasn,t sure how much clearance there was.Purchased my 500 packed up in pieces so I had nothing to go by.If you have the room go for it,not sure how much benefit you,ll gain but would be interesting to know.:)
Can,t fix stupid.:)
