powerhouse 750 plans

gee wiz, i hope someone can help me on this cus im really kinda lost about what to do. i plan on building this jacked up 750 ltd: 810 kit, k&n pods, 4-1 kerker, gpz cams, bs34 mikuni's, and a dyna s with new 3 ohm coils and plug wires etc etc... but it just dawned on me that i havent a clue what the carbs should be jetted at so i can begin breaking in the engine properly. my fear is that the bike will be sitting there running for 10 minutes while the mechanic tries to get it just perfect (which i hear can be kinda impossible with pod filters, just what my local shop says anyways...). i want to seat the rings as close to perfect so i can have all the power i rebuilt the engine for. ive talked to a few people and some are saying that the setup im shooting for would be stage three, but theyre also not entirely sure either. so is there anyone with a similar set up that knows what i should do? a friend says that if i can get it in the ballpark i can worry about fine tuning later after i get it all broken in. and for this kind of situation that im facing, its better to run rich right?

I have a 650 with the same mods as you except it's 720 cc and not 810cc. The only changes to my carbs were I went up 3 sizes on the main jet, raised the needle one slot and installed one size bigger pilot jets. Runs perfect.
My carbs are VM26 not BS34 so it might be a whole different beast.

cottoncandy I'm running that same setup, less your pipe I'm running a Bassani compitition (for a gpz 750). The BS 34's I have are, 152.5 mains with 40 pilots 2.5 turns out on the air screw. Buy a set of rebuild kits for the carb. I got mine from jeff at z1 and don't forget that you need 4 new air screw o-rings (they help). the kits don't have them. 29mm smothbore air screw o-rings work perfect. c-clip is in # 4 slot. by the way I'm about 200 feet above sea level. try to get the carbs setup before you fire the bike. you want to start warm and ride in that order. Later Dave.:woohoo:

those mains are huge! is that because of the 34s? what would the bike be jetted with if it had a set of 28s?

Was running 810 kit with stock kz750 cams, 29mm smoothbores ran 115 main with 22.5 pilots. then installed bs 34 started with 140 mains 40 pilots. needed 145 mains with the kz cams. Installed gpz cams last weekend and had to rejet again, its was on it face at 8000 to 8500. ended up with 152.5. runs to 10,500 no problem. and hard. Later, Dave.

thx, Im guessing that will be close to what I will need.

im so grateful for you guys chiming in but i dont understand what youre saying! i was under the impression i just buy a dynojet stage kit and have someone toss it in there... can one of you guys dumb it down for me. someone said to have it set up before i fire the bike up. how do i do that. by the way im a twenty year old newbie with a mechanical engineer for a father so if things cant be "dumbed" down and i can always go running to pops. but its like i said. i want to break the engine in to its fullest potential so i know the sooner i start loading those rings the better. i know i sound like a broken record here, and i apologize.

Relax, bro, it´s not rocket science. Just put 2 steps bigger mains and lift needle 1-1,5 slots. That should get you running as good as ya need for breaking in the engine. I dont know how you could set up the carbs "perfect" before first running the bike to see and feel what to do.

whew, i did some research and now i know what you guys are talking about. thanks so much guys. im off to fix the deathmobile

this is the post that i got the info to use 152.5 mains and 40 pilots for my jetting settings. so i know it can be done since theres a guy with the same carbs as mine and pretty much all the same settings. this

this post revival goes out to wired george. if this guy can get 152.5 mains, what does that mean? is he making this up?

no offense to anyone, just need this cleared up...
