Bandit-1216 rebuild,what direction to take

[MTBEERWAH]

G`day,
I`ve slowly been accumulating parts for this build,and seeking advise from a few- Joe Marshall, Alan Herriman, Holeshot Performance in the US, Startline Racing Brisbane. Now..i`m getting mixed opinons on corse of action.
Basically what i want to achive is more all round power with absolute reliability.
One says just do the 1216 no skim off head
One says 1216 gsxr intake cam .but 25 thou off head and flowed
One says 1216 both in/out cams no skim off head but flowed
One said do the lot,because "if set up correctly you wont loose power anywhere only gain over all,and the others don`t know what their talking about.
And i have made it quiet clear with all of them what i want to achive-More power and torque over all.Not a drag or race bike but something that will go well with absolute reliability and strickly no lose in bottom or mid range.
Thanks for listening,John.

All of the above

I'm getting Al Herriman to do my bandit, had a few chats with him and he's on the ball and understands "streetable".

[MTBEERWAH]

yeah i went around to his place early in the year.He will be the one i think i`ll choose, but he said he would only touch the head,and doesn`t want to be responsible for any other part of the build. He told me had a machinist he used to use,but now doesn`t do it any more,and was still putting his feelers out on another sorce that he could trust. I tried to talk him into the whole build, but is hesitant. I`ll keep tring,but i don`t want to piss him off. I did get along well with him, and he`s very swithed on and seams a nice lad.

thats very tempting, but hard to hide that bottle.So,i know jack shit about gas,how long does a shot last safely? how long does a bottle last,ie:how many shots? and the big one,what does that really do to an engine,i mean longivity?

My 2cents worth as I have owned mine since 1996 and still hums.

minimum of .025" off the head, more squish more power! (Check Squish Clearance!)
standard cams - (read shitloads of torque 89.76 ft lb)
5 degrees ignition advancer
40mm mikuni's with pods
standard diaphragm clutch
Will give you around 148 rwhp

just had carbs retuned (August 2011) and dynoed, same engine cylinder head has never been off since being built,only timing chain,2nd gear, shift fork and shims done since '96 and still has 142 rwhp.

Get the head ported and skimmed,run the 750J/K cams dialled in on slotted sprockets with a 3 angle valve job, and have 0.5mm skimmed off the head. Wiseco 1216 pistons, a set of Mikuni RS36 flatslides, a decent exhaust system. Run the carbs with velocity stacks and Ramair dual oval foam socks. make sure the pistons are at zero deck with no base gasket then use one stock Suzuki base gasket and the Wiseco head gasket which will give you a squish of 0.95mm You'll end up with a great torque motor which will work well on the street. I've just done one using stock Busa pistons, skimmed 1.2mm off the block, a 750J/K head and cams, RS38 flatslides and a Cobra 4-1 exhaust system. compression is 10.25 to 1 and 142bhp with 87lb/ft of torque. over winter the head will be ported and sorted and skimmed by 0.75mm to raise the compression which should pep things up a little from where they are now

[MTBEERWAH]

Now i`m starting to get confused,
as it is, i have got 1216 je 11:1 pistons,also got 1989 gsxr 1100 in/out cams(doesn`t mean i will use them)
Hagarr, i don`t doubt what your saying, its just after talking to Al Herriman,he basically said it was impossible to get over 115bhp with standard cams on a Bandit,now in saying that,has yours got 1216,or stock bore and only skim head,and no port work,but maybe just dialed your stock cams with 40 carbs,and with that skim gives somewhere around 10.8:1?

Dynomutt, how much difference between 1989 1100 verse 750j/k,if fuck all,i`d prob keep with 1100

A bandit with pods and jetting on stock carbs will see 120rwhp

[Hagarr]

Apologies guys '92 Gixxer not bandit Oops[:I]

[MTBEERWAH]

i had mine dynoed 4yr ago,and accordind to the chart,118hp 8700rpm and 81 foot torque at 6200rpm, can,filter and jetting,thats all, now if i believe that or not is another thing,i`m cetainly no expert on how to use or read a dyno,just after talking to professional builders with a good reputaion with the my same set,says by the nature of a stock bandit cam makes it impossible to make those numbers.
This is why it seems to be such a hard question to ask and answer on the total subject on what to do. Numbers mentioned in the 130-140`s from having fuckall done to medium to higher work done. If i know i could definately reach 130-140 with fuckall done, then that would be the coarse i`d take.

I know davio (oldskools mate) got impressive numbers from his and that was basically stock with FCRs

[oldskool]

ported and skimmed.
Angry cunt of a thing!

[Dynomutt]

Most Bandit 1200 with a stage 3 dynojet kit and a decent can will see around 118 to 122bhp. The cams of the 750J/K have the same exhaust cam as the 1052 but the intake cam is only fitted to the 750J/K, headwise the 750J/K has the same sized valves as the 11/12 but a combustion chamber volume of 22cc as oppose to the 11/12 combustion chamber volume of 26cc, this is why fiting the DOT head gets a good power increase because of the hike in compression.

Same here. I had 118hp, with just a carbon can and jets.
Im sure there is more to be found even WITH stock cam's.

First thing any bandit needs is new cams. I measured mine before replacing them, exhaust cam came in at like 260 lift and 240 duration while the inlet was only around 315 lift. crap figures. New cams, decent exhaust and carbs will certainly see 120+ horsepower.

[MTBEERWAH]

i agree with putting cams in for torque and power,just don`t want to loose ANY bottom or mid range by doing so,whether that be for intake alone,or by both cams

[evilkarl]

Yep no need to go silly, your max cam size is 370 lift before you'll need better springs, retainers, shortened guides and hardened rockers $$$$$$. I've gone with mild cams. More important to dial them in correctly for the performance you're after, twist them apart, so you'll need slotted sprockets. something around the 330-355 lift and 242-248 duration is excellent on these engines as seen by spec's listed on APE. I've got the mild spec from thier site, 330/330.
