Sounds like you're getting to the point of pulling the carbs and doing a proper clean and reassemble. I would also look closely again at your cop conversion since this all started after it. PS: you garage pics makes me think of the VMax article from the eighties where the two are lined up. I...

I've maxed my 83 Venture and have also installed a VMax final drive and a 2002 royal star Venture transmission (essentially the over drive 5th they're talking about). I wouldn't want a taller gearing on the highway, it drop?s the rpm doesn't around 3200. Much lower and it wouldn't be usable at...

Gave it a tweak before leaving work. Carb cough is gone, but it barked in the pipe once or twice on the way home. So one has gone a touch rich. Once it cools down, I'll pull the plugs and see which one shows touch rich and back it down an 1/8th. I may have a look at the wet float levels too...

Well, its snarfing a little bit now and then from the carbs. Acting like its lean. But its 1/4 throttle and under when it does it. Mostly on steady cruise or the occational throttle chop aftr light throttle. Idle screws need some tweaking....

Rode the bike to work this morning. Warmed up normally with a little choke, rode well with good throttle response and no lean pops. Little bit of chugging from 1000 rpm in second gear with throttle, but it did that before and i was able to clean it up with a little fuel screw fine tuning...

I use an old tank from a snowblower I had that chucked a rod for when I have to run bikes without a tank. Looks like this: I have a couple "hooks" on it that allow me to hang it off the bars and it has a shutoff valve that I can turn on and off. It just gravity feeds the carbs. This is all...

A couple guys have gotten around it by "dinging" the frame rails right above the rear carbs to give them the inch or so needed to get the carbs out. I refuse to sacrifice the rigidity of the tube so I have to drop the engine for clearance. Sure, its a PITA, but once the carbs are sorted I...

I've got a v45 interceptor too. Only hard part is getting the carbs in and out of the carb holders. The Yammy holders are at least all vertical and fairly easy to get the carbs in and out. The v45 has them all at an angle and getting those f-ers in and out is pure hell...

If you think that's bad, consider this: since its in a Venture frame and the top frame rails don't pop up as high over the carbs as a VMax, I have to pull the front engine mounts and lower the front of the engine in order to get enough clearance to pull the carbs out of thier rubber holders...

Nope. pulled and split everytime. not really something you can do on the bike.....

Alrighty! It's been all day again and now getting late. I decided to throw all the specs and tests in the manual out the window and go for a hail mary pass. I set the dry float levels to 1.125 (as mentioned in the carb sticky) buttoned it all back up and cranked it up. All the carb needles...

reasonable thought, but the needles are oem for the carbs as are the emulsion tubes. I'm testing without airbox at the moment and still the fueling problem. Another reasonable thought though. Puzzled me too. Nearest guy who woudl have a rack I could test with is at least an hour and a half...

they work fine and they aren't subject to the wear rubber tips see. They also don't take a set to the seat and stick (unless they corrode and then you have other more pressing problems). I'm chasing down a problem here, not looking for personal preferences.

well, did a live "wet test". holds at 17-18mm. so its not the pump over powering the seats. ii have to be missing something simple her and i just cant see it......

yes,metal tips. this is an xvz12, not an xvz13 or vmx12. 83-85 is the same as the xv535. part no. 22u-14190-15 tip material is irrelevant. its matched to the seat its used in.

sunova...... runs fine for a while, then seems to swap which carb is going to spit fuel out of its needle. then, #4 up and overflows while im fine tuning the synch! im going to replace the damned float needles on spec. they look in fine shape, except that theses all have a metal tip and not...

ok. got them all bench set at 18mm. they're going back in now and fingers crossed....

Those numbers are very close to the stock venture numbers. I don't have them right at hand at the moment, but they're close. 83-84 ventures were 42.5 pilots and then they went to the 37.5 in 85, vmax followed suit in 85 with the 37.5's. Lots of venture riders actually swap 42.5 for the 37.5 in...

Venture 1200 block. 31,000 kms on the rotating assembly. All VMax from the head gaskets up to the carb boots. Its the 34mm Venture carbs. Pilot jet 42.5 (all stock for an 83 1200) Main jet 145 Venture manual calls for 14mm +-0.5 for float levels. Too high for this combo so I'm using VMax...

Alright, I'm po'd at this thing now. It seemed to be pretty good, except it has a bit of lean surge and mileage is 18 mpg! Yes, you read that right:, 18 mpg. I didn't think it was possible either, but there it is. checked my math several times. Even of I'm generous on my numbers, its still...
