BEET 441 Monster Motor ( I hope )
Posted: Fri Jul 09, 2010 7:44 am
Been gathering up the parts to make a new motor for the bike.
Initially it started out at just SP 33mm FCR's & SP cam's with the Race CDI & Pulsar. Then I chanced upon F3 racing cams from an ex-Kawasaki team technician - they have also had additional case hardening done to them and he gave me the F3 manual thats been posted up.
I then got a H1 motor which i done the strip down thread on, and went about porting and polishing the head on it.
Then a SP motor came up and I snatched that and stashed in the cupboard, next was a ZX-4 motor , then an L , then an F3 SP and finally yesterday a ZX-4 with BEET big bore pistons
The latest motor was utterly boggin so spent the morning washing it down with kerosene and parts cleaner before making any attempt to strip it down.
As soon as the rocker cover was off I instantly noticed that the cam's have had the F3 modification done to them for racing
I had studied a pic' of the BEET kit last night so had a good idea of what the pistons should look like, so once the head was off I could confirm it was a 441 block
Once the block was off I could then see this on the pistons:
Some shots of the rest of motor:
So once this one has cleared the bench I'll get the SP engine out (already stripped) and start preparing it for putting the crank in again.
The final spec'
F3 Slotted cams
F3 Ported head (maybe new Ex & In valves)
BEET 441cc pistons & block
New camchain , blades & tensioner
Polished & weight aligned conrods
TGN Dynamically balanced crank & new shells
Clutch new plates & steels
SP gearbox
All O rings , seals and bearings renewed
Complete engine gasket kit installed
External
Bito R&D 33mm FCR's with 50mm Trumpets
BEET side casing
BEET full Titanium Exhaust
Stick coil mod
F3 Racing CDI & Pulsar rotor mod
Earls Oil cooler with braided lines
Just to find the time & space to do the motor build - not keen to build it outside as my workroom is wall to wall with parts just now
