[suzuki139]

hi, i am looking to see if anyone would have a pic of the under side of a twin spark head, i am looking to see the way the 2 plugs are placed..thanks

One in the middle as per a single plug head, one off to the side between inlet and exhaust valve, either to the left or right depending which cylinder.

dose anyone know if this effects the head when getting them tunned

Yeah TWF tried it, 2 motors with same modifications, they lost power with the twin plug heads.

IMO use curvy heads, don't have the PAIR system envirobollox to deal with then either.

dose the none twin spark heads bolt onto a k8 twin spark engine, and can you just use single plug coils

Sid Squid.Is there a big benefit in fuel consumption in attempting to covert a K5 to a two-plugger?

Tuned some twin plug models they work well if done correctly no issues at all, both in 650cc and 700cc form, they actually run very well.

Just block off the pair system aslong as your not running to minitwin specs if running the pair is an issue to you.
