Awesome, good luck! I’d be interested in that kit from Pete if your selling it?

Sorry already sold it. But if you need one, I think you can build it yourself for around 1200~1500 dollars or so

Where in the states are you? Looks like a kit from Pete. I have one also 

Hi, yeah it was a Pete kit, but i got tired of if, it was running fine in the end, but carburetor is not for me. So I’m starting to build another turbo setup with gtx2860r gen 2 and fuel injection

I’m done with carburetor, bought proboost adapter but is different of what I thought that I was going to get... pretty disappointed to be honest...

 

im going to convert it to fuel injection using Fueltech ecu

I just reread what I wrote - and it doesn't make any sense ! ! ! Why would anyone vent their carbs to the fuel tank ! DOH! If this was a EFI system then yes the bypassed fuel return would go back to the tank, even a high pressure pump with regulator and back to tank - either way they should be above fuel level otherwise a syphon could occur when shut off which would backfill the carb and into the engine ! ! ! 

But I do have a fuel pump and a regulator, then the return is using this tube for a fuel return, just like a EFI system

Your fuel return pipe needs to be higher than the fuel level in the tank, otherwise fuel will drain back out via this pipe. 

The fuel return is using this pipe, so I don’t need to weld another return, the return needs to be under the fuel level, no? So it doesn’t create bubbles that can be sucked by the fuel pump

I'm a bit confused as I thought Blandits tank breather was through the gas cap? That hole is normally the fuel gauge and if that pipe has been fitted in that hole its non standard. As said the pipe should go above fuel level - at all times - if being used as a carb breather!

Turbo bikes aren't 'plug and play' - really you need to start with a bike that runs good NA, then big bore it, then when that is running ok, turbo it! You seem to have a lot of problems that could be caused by a lot of things ........ maybe take a step back, take turbo kit off and get it running half decent first?

Yes they are, they go all the way under the tank to the gas cap, I cut it so I can use the tube for a turn left, is not a carb breather anymore

yeah, I thought about that, unfortunately now is too late, I don’t have another exhaust... I still can try to run the bike without the fuel pump and everything, maybe I’m going to do that, start over

Adjust by bending the tab on the floats. 

Yes I did that, I just didn’t the exact place to measure, because the top of the carburetor is not flap, but now is parallel to the body, I think is at 14mm

From memory float height wants to be 14mm, measure in middle of the float as float opens. Float valve  have little springs on them. You can rotat the carbs to see this working need to be set as these are just about to open. 

Yeah I did that, just didn’t measure the height, just placed then aligned to the body

Is my first time doing a Turbo motorcycle, it was always a dream to own one PS: my English is kind bad so excuse me if i write something wrong

Bought a Bandit 1200S 2000 with 41k miles

I got a Turbo kit for my B12, and some Hayabusa pistons, bought new OEM needles and springs because it had different parts

replaced the gauge for a TFT one

But now comes the worst part... When i got everything installed the return was a little restrictive because i used the breathing tube from the gas tank and gas started to go inside the plenum and inside the turbo, was a huge mess, the floor was full of gas... then i cleaned it up, even cut the tube even shorter

 

tested the fuel pressure without the gas tank 2psi, then tested again with return connected to the gas tank, 2 psi too.

but the motorcycle was still not running well...

then i removed the carburetor and checked the float weight, they were not aligned, so i didn't know how to check the height because the float surface is not flap, so i didn't know how to setup, so i only made the float line parallel with the body, i even used a caliper to make sure that the front and back were at the same height

 

but the bike still running bad... I'm tired and frustrated, i would really appreciate some help

btw, the oil pump is sideways, is that ok? because even to i let the pump run for a few seconds after i stop, the oil still drips to the floor, and is a very dark oil, i think it is oil with gas, but I'm not 100% sure

Thank you
