Building Ultimate 5K

[springersrolla]

Hey lads, plan to build my 5k soon and wanna know if there's any suggestions or ideas on what way to go. I've been collecting bits for years and now have... Twin 40mm webers with manifold, ported 5k head, electric dizzy and pacemaker extractors.

 

Now other than a cam and a balance is there anything else I can do to make more power??? Any ideas will be tops cheers

Love that vid.

yeah man all over that guide, built a few 3ks and such but never really worked a 5k, just weber and extractors. now i got the twins and the worked head just curious what others have done with ther 5ks and power they got, its only ever gonna be a weekender. i saw some gillys for sale the other day, ther alright, not really in to them, sick car but

You gonna run solid lifters or get the cam ground to run hydraulic?

What pistons do you have flat or dished? Want to go high compression?

[springersrolla]

cam is hydraulic and will leave it that way, no solids, i get the shits with adjusting rockers. Pistons are standard, bores are slightly oval shaped according to my inside mic's. No idea on the piston scenario of dished or domed or what. i know ther was info about 4age slugs and suzuki bike pistons also i think.... compression would be great but it will only recieve ultimate so 9:8 to 1 to 10;1 will be the desired ratio.

 

No other options i can think of really stand out, i have adjustable cam gear, will get flywheel lightened, bottom end balanced, other than slugs i think its all i can really do. n/a of course

How long do you want it too last and how much money do you want to spend.

 

Block dipped, bored 1.5mm, blue printed

Dry sump oil feed

You could have your crank knife edged, shot peened & polished

Forged and shot peened conrods

Polished and balanced cam with grind

Roller rockers on a micro polished rocker shaft with double valve springs

Over sized titanium valves

Ceramic coated extractors

Electric fuel pump to delete mechanical

Crank angle sensor with quad coils or magneto ignition.

 

I could just go on.

Motorbike quads instead of twins...

[springersrolla]

yeah nah not overly alot of money its a stinking ke35! i have the webers and head, more just after bottom end info and what not, ideal cam, knife edged crank maybe, how much success is acheived from all that hard work? is it worth upping compression ratio or just skim head an be done with it. i don't wanna spend to much on the rebuild

For the win :jamie:

I've got a set of FZR1000 Mikunis here doing nothing lol... Do it.

[springersrolla]

ive got a set of twin 40mm webers with manifold, that was running on a 4k..... doenst make sense to try swap all shit over to something and make manifolds when its sittin there. would be hell ʞ©$ɟing cool but

[67Rolla-Ken]

It makes plenty of sense, someone will buy your weber setup.... go the quads!!

Webers are ssooo much easier to get your low rpm and low/part throttle perfect. I've tuned both and id I'd have a DCOE style carb over a bike carb any day.
