MA10 Carb and MA12 Carb
- Thread starter K10251
- Start date
Worthwhile:
Drain cooling system & refill with new?
new thermostat while you're on?
new thermostat housing gasket?
new carb plate gaskets?
1 hours work maybe
then most of this again if its no good
IMO not worth while for the small gains in some areas (and probably losses elsewhere)
....but there again I've never tried it myself so I' just speculating really

yup the ma10 carb has bigger jets and that is proven we knew this about 5 years ago lol.
replacing the carb is an easy job really takes about 20 mins if you've don't it before. needs new gaskets when you change it other than that nothing else has to be changed. i remember way way way back in the day one of the old skool k10 owners did this and said it did make an improvement

Inlet Manifold
Ok, so weve decided that it's not really woth changing the carbs over (even though i may try it on sunday just because i have a spare carb).
But it is worth getting a weber (or su).
The only real problem then is the inlet manifold and the exhaust.
My question is: Does the inlet manifold need to be a calculated shape/volume or doesn't it matter?
And i don't need to ask about the exhaust because i am going to fabricate my own one in my spare time.
cheers

CORKER QUESTION!!
throttle bodies included in this question too would be an interesting option too..
I know BOB can fabricate inlet & manifold combos (BOB are you still into this?)
I have to admit, I am fairly interested in the individual throttle bodies / 4 inddividual carbs route for my further work.....bike carbs are becomming more popular but I would really like to know the theory / principles too before chosing a solution..

I dont know much about carbs and stuff, with what I know, with individual carbs, theres less inlet manifold so the fuel and air can get straight in the cylinder. They also let the full amount of mixture the cylinders require.
Thats about all i know

it does but performance is alot better for a 1.2! obviously you will see better gains on bigger engines.

a 10% gain is the difference between a 1.0 and a 1.2 and there is quite a difference in drive-ability between the two engines.
