cag/blata hybrid

[redheadracer]

me and carter have been working on a cag/blata hybrid project

the motor:
STOCK bottom end (stock crank)
40mm flat top piston (from a watercooled)
40cc barrel NO boost ports
a/c blata head modded to fit
stock ported and rejeted carby
STOCK tin reeds
exhaust port spacer

The motor


the motor in the bike


note how i had to cut the head to make room for the pipe


with this setup the motor had a very very good top end power (for a stock crank any way)

but in an attempt to get some lowdown power i put a timing key in it
and that sriped one of the head bolts

so tomorrow i'll rebuild the motor with all the good stuff (and a fc crank!!!)
stay tuned!

and bye that way this motor/head set up should have around 16:1 comp

dont forget to put the dellorto 14/14 carby on it too!!!!

[m-sherborne]

what sort of pipe is that on this motor?

cheers matty

[redheadracer]

the pipe is a badazz power pipe

and once i find a manifold for the 14mm i will put it on

[r1_rider]

ok i'll see if i can give you my spare manifold next time i see u at the track

[redheadracer]

today i made a bottom end to match the top end.

bottom end:
fc crank
c4 bearings
better seals
2 gaskest
i made studs that screw in (that will stop the head trying to jump off)
i set the squish up right to its .54 now (it was .25 when it sripped the bolt)
i put a cutdown bizeta reed in it (to match the bizeta piston in it )
i put a 14/14 dellorto on it too (i made it fit)

test:
once it gets to around 5500-6000 the power band kicks in and it really pulls
but... its only got the stock ports in it so once i put a big fat boost port in it, it stould have a lot more grunt and rpm (atm it only pulls 11000)

and tomorrow once i get the motor sorted i'm might try a slipper clutch

[r1_rider]

nice.

how did u put the delorto on without the proper manifold? did u bore out a cag manifold or somethin?

and what's a 'slipper clutch'???

[redheadracer]

i got a dreambike/banshee style manifold and redrilled it

and a slipper clutch is just a adjustable clutch

[r1_rider]

oh ok. so u dont need that one i've got then?
