Transmission Problem? Bandit 1200 motor

[stetracer]

As far as the Bandit rods, they can handle well into the 200hp zone if you don't use really heavy pistons or really high rpm.
Of course this assumes not making the mistakes mentioned above (wrongly engaging the nitrous system).

I strongly disagree with you on this. Your playing with a time bomb. The bolt are weak on the Bandit rods. Also I would recommend a progressive nitrous controller. I always play on the safe side

Jim,
What kinda of time are you running with your set up and what is your chassis set up? I am sure the op would like to know. I would like to see a pic of your bike. I believe I have seen your name at Maxium-Suzuki

Mark,
looking at your pic of you bike I would change the position of your bottle to angle the bottle upwards slightly and check the bottle to make sure which way the tube is angled and then mark the bottle so the tube is facing down if there is no tube then the bottle needs to be mounted upside down. Also check how the nozzles are pointed the should be pointed straight done the intake track. If you need any help you can call me 941-391-1410 I just lying around here in the hospital STILL.

If I remember correctly, a couple of years back, Dale Walker (Holeshot) put together a max effort street Bandit with a primarily stock engine and came up with about 160 hp as a reliable daily runner.

JD,
Your arbitrary 180hp limit is not the correct way to analyze the rod situation in my opinion. You are ignoring big factors on rod stress, namely piston weight and rpm. Since the OP has stock pistons and stock B12 cams, he did not add piston weight and he should not be running really high rpm. I have run the B12 over 200rwhp (with the help of a nitrous system) on the stock oiler rods and it was a 'worse case' than for the OP because it had aftermarket pistons and revved to 11000. I also know someone who ran much more hp in an oil-cooled than I did, using stock rods and stock pistons. Do I feel more confident in what the motor could take, now that it has Carillo H-Beam rods? Of course. We'll disagree on stock G1 Busa rods too because my opinion is, if you go through the trouble to pull an oil-cooled motor apart to change the rods for a performance build, then use either Carillo, Crower, or Wossner rods.

"primarily stock"..opinions vary and dale is in the business to sell parts/make a living.
when i bought my bandit new in early 97 there was near nothing available so i worked with what i had and on a low budget.
IMO much over 130hp requires the head being removed and then i'd have to throw "stock" anything type of phrase out the window.

Stress on the rod will increse with the addition of added compression and adding No2 will increse the stress on the rods
The use of the water cooled GSXR 1100 rods which can be had for $100 a set is a well known up grade to the Bandit rod with out having to do any other changes or spend $700 to $900 for rods. The use of Busa rods is something a little different a lot more involved. The reason I am using Busa rods in my build 1340cc is because it is over kill enough for me and you can find them new or with no miles for $100 for a set if you are around the drag strip enough and buddy up to the Busa guys they are super strong for stock rods. I have no problem with the after market rods there great if you have the money to buy them but are over kill for 200 hp. God knows I believe in over kill but not to that extreme. I don't feel going into the bottom is any trouble just a little extra work

Jet kit, full exhaust, and drop in GSXR cams will get you over 130 hp easily
the build he is referring to was a collection of Bandit parts he sells and the head was ported by him
