Has anybody used this kit( Zipper's 80/80 Evolution® Big Twin Kit for EFI Models) and your thoughts?How well will it hold up?Any info appreciated

 

Seems kinda over priced if you are talking about this one

I think if you used your own heads and jugs you would be able to do the same thing for quite a bit less.

As for how well it will hold up from the specs I think it will hold up just fine.

 

That price is a bit over the top in my book.

Nah Way Over

For that kind of money I think you can go to your local Indy and have him stroke your motor. not you pocket......

 

That is a ridiculous amount of money for a hop up kit when you can get a s&s v111 for 5 grand

 

Wow, I'm offering a 100/100 complete running Evo engine for almost half that price, maybe jumping the price up to $4000 would make it more desirable

 

Not if you actually read what is in the kit...the Magnetti-Marelli conversion kit cost $2425 by itself...so if you are hell-bent to keep the EFI and don't mind spending the bucks, it might be an OK deal.

BUT you could get a lot more HP for that amount of money if you dump the EFI.

 

WOW, like Dejavu, That was the first thing that came to my mind...

 

Correct statement on being a good kit if hell bound on keeping the EFI, the Evo responds so well to a prehistoric drip carb, just struggle on the coin to still only have 80 hp when it can be achieved cheaper with some of parts already supplied on a Evo.

 

I wouldn't buy new heads for any bike, except as part of a complete engine. If you are keen on improved performance, simply pick up the phone and talk to Scott at HDF sponsor Hillside Cycles. I'm sure they can give you more performance at lesser cost, with 90 HP/TQ for an 80", or 100+ for an 89" stroker.
