Motor choice

[rodneya]

Got an opportunity to buy a new motor and have two options. EFE motor with 1200 kit and cams ( cant remember what the guy mentioned at the moment) or a 1127 oil cooled motor from a late 80's say what now!? and looking for some opinions.

Motor may go into my Katana, or a future project. And yes I would like both, but I dont think I can swing that at the moment.

Definitely the EFE

[gsx]

^^^ what he said 

[TonyGee]

yep, EFE engine

[busa ash]

efe motor in your katana  great upgrade and what a lot of people have done 

[wraith]

And one more for the EFE motor, if the worse comes to the worse, you could sell it next year for more than you payed for it now lol

[Dezza]

+1. Not much of a choice really as EFE engines are fast entering the 'rocking-horse-shit' category of bike bits.

[rodneya]

Well EFE it is then. thanks.

the oil cooled motor is my favourite engine but are 10 a penny and you could get one anytime, the EFE engine though is getting almost impossible to fine so strike while you can.

In the UK maybe, but in Canada there are not that many that I have seen for sale. Water cooled motors are a different story.

Depends on the condition of the engines.

good oilcooled engine > broken EFE engine

unless you want to spend 11ty $$$$ to fix it.

EFE in a Kat all day long. Keeps it period.

Gsxr in kat, all day long, saves 3 stone and an  additional 20 bhp as standard.

Yes with 1200 and cams in the EFE that sounds realistic

or another £1000+ minimum, to put said cams and big bore kit into efe yes?

and its still 3 stone heavier.....

[Joseph]

It's still the best option

Unless I'm reading the OP wrong - the EFE comes with the cams and 1200 kit fitted so no additional expenditure and 'comparable' power but much torquey ! I do love the Oil boilers but a Kat deserves the OSS anchor!

For me it comes down to what you want from the finished bike.

If it's performance first and foremost then it should be the oil cooled lump as they're lighter and have more power 'out of the box' so any additional spend will be give gains from a higher starting point so the cost per increase over original will be lower.

If it's 'coolness' then you go for the air cooled. Air cooled lumps will arguably look better in the frame, and you don't need a ruddy great radiator hanging off the front of the frame.

If you want coolness and performance then get ready to be poor.

EFE all the way
