Yeah, hi so I'm the end for me I was running way to rich which was causing a lot of spluttering and stuff so I raised the needle (obviously in your case you cant) but I have lots of liquid on the intake manifold too! I may be able to help here. I assume most people have a tube of holts exhaust gum or whatever you 'muricans use but a pea sized blob on a piece of carb and with knife I applies a tiny bead around the intake manifold and it sealed it up nicely  don't use to much or when you tighten if up it will squeeze out into the reeds+ engine  I learned the hard way. |

Frankly, I'm giving up on this thing right now. It's pissing me off. I can assure you that all or at least most of us feel the same way. I've tuned many times, especially doing projects where I was changing something daily, and it still drives me crazy at times. It makes more sense to walk away for a bit than to be angry with it and take shortcuts or work yourself up. Now it feels hot as hell and I'm now finding the top of the air intake (on top of the reed valve) is wet? First off, this air intake is a pile of crap because you can't access all the bolts right so you either get one not all the way tight or you strip the living daylights out of the head. If you have an air leak (most likely unless there's a fuel leak nearby) then forget the tuning until it's fixed. Air leaks are a pain and why myself and some others here believe that a leak tester should be a part of every 2T builder/tuner's tool kit. Even small leaks can about make you wanna pull your hair out sometimes. I've spent my entire day trying to tune this carb and I feel like I'm just dealing with another crappy fake that I'm just wasting my time with. Could be the carb, but I suspect something else is up. I've used quite a few of the cheapest I could find carbs from eBay and had them do just fine. Easier said than done, but try to keep in mind that at least the tune should last a while. It's not like you'll be tuning it tomorrow once it's done right.... well unless the temp changes.  I may have to mod the intake or switch over to front facing and figure out an air filter situation. I can't stand not being able to tighten it down right. It's got gaskets on both sides of the reed block and I can't figure out where the wetness came from. Minarelli reed blocks and intakes have always been a source of leaks for me. Not necessarily so bad that I get fuel puddling, but at least to the point that when everything seems like it should work they don't hold pressure when tested. This is why I always use a sealant on my reed gaskets. Makes cleanup a hassle vs just gaskets, but if it's not leaking I don't take them apart often. Sorry it's all being a pain, but figure out where that fuel is coming from for sure first and don't bother with anymore tuning until you are confident that you have no air leaks IMO. |

Have you done a fuel flow test?Sounds like its running outa gas..Have you got an inline fuel filter on it?Petcock screen clogged?I think you are cussing a poor little carb due to poor fuel flow....

I to have been there, and it aint fun bro! It has just started getting a little easier for me, sometimes. I think you are on the right track, you gotta get the airflow consistent and predictable, period. Do whatever you have to to get the intake issue resolved. I have a VX50, but it does not run at this time, and it was damaged from 2 ice storms. I have not looked at my VX50 that closely, so I don't know if a forward facing intake will fit or not, but if it will, that would be your best bet I think. Along with a stock airbox, you can begin to end the madness. Front facing with a stock box won't happen. Not unless I do like 90GTVert and relocate it with a hose. Which I'm thinking I'm going to do. Which will also make removing the carb easier. Though it will be blocked more with the panels on and will also be susceptible to heat from the head. |

Sorry it's all being a pain, but figure out where that fuel is coming from for sure first and don't bother with anymore tuning until you are confident that you have no air leaks IMO. I'd need a list of tools for a leak down test setup. Honestly I'm worried seeing the fuel there. I partially blame the damn intake and how it's in the way of the bolts. I'll try to put the front facing intake that niz76 gave me and use the hose I got to move the filter. I can't do a front box and the stock box was leaking from all with a shot gasket and the main hose is not tight in the box. So I can either relocate it and silicone the hell out of it, or get the Uni filter to work with the pod. The thing that scares me though is that this was happening before with a sealed up reed valve and I kept suspecting the carb. If it's not that, then it's a seal and that means what, taking the thing all apart again? *sigh* I'm not looking forward to that. Not to mention the labor it takes just for me to spend a day carb tuning, I'll have no choice but to drop this thing and bring it in the house to take it apart. That is going to be more of a mess I can't handle. My place looks more and more like a scooter pawn shop and my landlord will have a baby if he sees an engine in my livingroom lol. FYI. I don't have the stock reed valve/cage on here, it's the Hoca I ordered. I just didn't use their intake, it's way too big and I'd have to buy a stepdown tube to make it fit my carb. |

I was thinking of this too. The filter barely has 100 miles on it if that, it's a Visu cone filter. The petcock is not much older than the filter and it seems to function ok. Though I have manual shut offs on the way so when they come I'll be eliminating the petcock all together. There's always gas in the line to the carb though so I dunno. Stuff like this is why I wish I had a 2nd pair of eyes there but I have to just be patient. That's why I'm walking away from it for a few days till I have time to actually waste on it. |

Carb tuning can be such a pain! That's one of the main reasons I miss my Baccio- I could do jet changes lickety split because I could get the bowl off without taking the carb off- probably because it had the TaoTao Evo body panels... If there's a leak at the intake then nothing you do will seem to work. I know you're getting a lot of (great) advise already but I figure I'll throw my  in also: Ditch the intake gasket! When I do my intakes I always do it the same and haven't had a problem yet- I clean the case thoroughly where it mounts and scuff it a bit with sandpaper and finish up w/ carb cleaner to remove any grease or residue or even oil from your skin. Then I take the reed cage and do the same- scuff both sides of it and clean w/ carb cleaner. I use a nail or rivet to apply Moto1 ultra Gray evenly in a thin layer then do a 2nd layer a little thicker... the idea is to scuff everything and clean thoroughly and and make nice "gaskets' with the Moto1... Like I said you're getting a ton of good advice I just thought I'd throw my 2 cents in! Eventually you'll have a great running scoot and go to the beach to pick up a chick to clean the house for you ;O j/k j/k! (kinda)  |

Eventually you'll have a great running scoot and go to the beach to pick up a chick to clean the house for you ;O j/k j/k! (kinda) LMAO! That's my next move. If I can't get this intake to seat right at all, I'm going to have to use the front firing one. Either way i'm going to ditch the gaskets and seal it. My issue though is it did this before with a sealed cage.  And I'd hate to seal it if I'm not sure of the config. So I'll have to wait till I have an entire day again to toy with it. You know, dry fit everything and see how I like it and if it works space wise and all. I have Motoseal and Ultra Black. I have just about every damn gasket maker now because of this place lol yet I've only cracked open the Motoseal. I haven't used the ultra copper on the exhaust because that seemed to seal up with a gasket just fine. I dunno. I may take it off and put some copper on that too. But the intake being wet I'm hoping was a fluke. I was worried it was coming from the head, but when I peaked into the shroud, all looked fine. I'll still inspect it for any reside though. The engine sounds fine though when it runs so I doubt it would be from there. I still need a friggin garage to do this in, lugging everything in and out of the house every time is killing me and my back is not liking this too much either. |

don't use to much or when you tighten if up it will squeeze out into the reeds+ engine 
I learned the hard way. 
And I'd hate to seal it if I'm not sure of the config. So I'll have to wait till I have an entire day again to toy with it. You know, dry fit everything and see how I like it and if it works space wise and all.
