another tach question

[Viirin]

You guys are probably sick of hearing the question "will this tach fit?" but i gotta know before i buy this one....will this one fit?

So according to some of the other threads i need one that is set for duel firing right? this one says it is but it says it'll fit any V twin...and there in lies the (first) problem...2 cylinders but not a v-twin right?

I've seen a couple of pics of other GZ's on here with tachs but some of them seem to go up to 12...this one only goes up to 8 - is that enough?

Does the gz have a 52mm cable to connect it or is it a different size one?

sorry about all the questions but i'm saving up my money to get a rake load of things done to the bike during it's next service and i'd figure i'd add a tach to finally get the idle perfect, but also for curiosities sake

Cheers for any responses guy! :2tup:
