bandit cams

[crainer]

Anyone tell me the best cams to use on b12 engine apart from standard ones. Heard gsxr 1100 cams are a good upgrade. If so what year is best?? Tia

The m cams will be no good, I've looked into this myself and apparently j or k 1100 ones or fit a 750 dot head which gives more compression, got one for my 7/12 I'm about to start

M and N cams are a shim head so not for a lock nut head.

I've used 1127 K cams on a few bandits. But That's only because I had a few sets lying around. You be able to use any of the 1052 cams and K and L. Never used any 750 ones so can't comment on weather suitable or not.

i have the same idea for a bandit donkey sat on the floor i was thinking 1127 cam,s off a k ? but good one,s seem hard to find.... unless we buy some lumpy race stuff ? i am sure we will get the right help here,

Same, I'm doing a 7/12. I have a spare 750 slabby lump sat in the corner hoping I can use the cams from that. Sure someone will be along soon to give us the right info

Think @fatblokeonbandit might know.  Now to see if the tag function works.

All the single lobe cams will go but ust slinging lumpier cams in won't necessarily make it produce more torque and power or run better or be more driveable.  Think about what you want out of the engine.  I've had my fingers inside the 750s for a few years now and got decent power out of them with the standard slabby cams.  It takes quite a bit of work to produce cam graphs, valve to piston graphs, choke/port/valve area ratios, then determine the best cam timing within the limits of valve piston clearances etc.  I found that the standard cams were perfectly matched to the engine when the timings were set up correctly.  Not necessarily where the timing marks say.  In my experience slabby 750 cams were perfect for the 750 and for bigger engines too, providing the whole thing matches from bellmouth to exhaust.  Might not be what you wanted to hear as it takes massses of time to get the set up, but it is the only way to be sure you have got the best set up that you can.

Ive done a few b12's with various cam, best bolt on do nothing else were 750J/K cams, 124 rwhp after dynoing with pod filters and home made stubby can,  I used b12 timing marks as I couldn't be arsed degreeing them, all worked wonderfully,

My harris has a b12 with 750 j/k cams in it at the moment,

I put a Flowed 750k head with cams on a 1052 lump standard cam timing cos as FB says couldn't be bothered to get cam wheels slotted and degree them in. Goes like shit of a stick.

I know recycling is good but the best bandit cams I have found come from Folkstone

As has been said , any of the 'none shim head' GSXR cams will work well in a Bandit 12 motor . 

Here's a graph from one of my experiments with cams from years ago - the GSXR cams used for the graphs were actually from a 750H and gave great results .

The SUZ 1 'race' regrinds that i got were piss poor and went straight back to Kent Cams , i actually ended up using the SUZ 7 'street' grind which gave great power & torque on this motor

This is why this forum is so good , plenty of knowledge on our old suzuki s 

[jonny1bump]

Suz 7 Kent regrind.

Lee got greedy going suz 1 with his combo.

But as said above its the combination of all your parts is critical throwing random parts will not produce good power.

Thanks everyone for all your info. At the moment the only mods are filters and exhaust. I will try my slabby cams in there and see what happens.

used 750 dot head cams aswell, timed up to standard bandit 12 specs,
