sync

Thanks for everyone’s help in getting my '88 VMAX carbs MOSTLY sorted out. (Special thx to Sean @ Morleys Muscle for sending my new jets so fast.) After putting the completed carbs onto the bike (with stock airbox and no air leaks) there’s still a very high idle and I’m unable to get my left...

Service manual says to stand the bike on a level surface by putting on a stand to sync. Why would the bike need to be level to check this?

Does anyone know the thread pitch on the carb sync screws? I'm trying to find one for the right side linkage if they are even different. 6mm by? very fine thread. The screw is stripped but threads are ok. If had hair to pull out I'd have had at it. I finally pulled the carbs flipped them over...

Can these not work properly? This is why I ask. I sync my bike, and if I think works well. I let my buddy use it on his Suzuki bandit 1200 sv and he claims he runs worse when he gets them all in sync according to the tool. So he approaches it (tuning) free hand, going by sound, response and...

I know this is posted in several locations on the forum and....here's one more. :biglaugh: I will refer to the carbs by their factory designation, following is the orientation front #2 #4 #1 #3 rear The first photo...

I'm trying to sync my carbs with a new Motion Pro tool. The picture shows where the fluid stays no matter what I do. If I turn the A/F stews on #4 or #2 all the way in the bike acts like it will stall. #1 or #3 turning the A/F screw all the way in does nothing. Bike sounds normal at idle and...

Would anyone be ok with loaning me their carb sync tool? Things have been a little tight lately to fork out the cash to buy one, and I really need to fix this bike up. I've seen some videos for these homemade manometers but I just cant see that being accurate enough. Im in New Orleans, Louisiana.

Does anyone have their #3&#4 sync screws all the way in? When I sync with my motion pro those two are all the way in,when I back them out the idle shoots up like crazy. The bike runs great and I have 4into2 full ufo exhaust and stage 7. Is there something I need to do or what?

Hey Vmax Pros, I bought this 86 vmax a few months ago and have been working the kinks out of it ever since. When I got it, it had horrible gas mileage--like 18 mi/gallon. I did a shotgun carb clean and brought it up to 32 mpg at one point, but it was misfiring a bit, so I did a vaccum...

Today I changed the plugs and was going to do a sync with my carb tune and I left the number 2 plug wire off by mistake. To make a long story short now my screws are all out of wack and cant get my idle down below probably 2000 rpms because the idle screw wont do anything. Every time I screw or...

Hey guys, been awhile. Have something really weird going on. Inherited a relatively new carb rack from a friend. Put them on my bike and started doing a sync. The first 2 steps work just fine, but when I try to sync the right bank with the left, I have the sync screw completely bottomed out...

Well finally got my homemade synchronizer to work. Instead of the plastic gatorade bottles i used two glass pickle jars and it worked perfect. I'm extremely surprised at how much better my bike runs now. Throttle response is much crisper. I only took it for a quick spin down the road but i can...

Sometime my A/F air fuel screws will came out of sync. I was trying few ways to make them hold up longer with out using something on the a/f screw to stay longer. I tried a few different things and this is what I came up with and it works for me. I been riding the bike hard and took to the...

For you motor gurus - Damon just posted something interesting in another thread - "Erratic idle when hot" Quote - "When was the last time your valve clearance checked and/or adjusted? I have seen when a valve adjustment was needed the idle rpm & vacuum readings would be bouncing all over...

I have got my carbtune today is there a master carb to adjust the others too?

So I did the shot gun method. The brass plugs had already been removed. Diaphragms are black, no felt around the edge. They look to be in good shape, no holes, guessing they have been replaced (thoughts?). Counted mix screws in 1/8th turns (19, 24, 22 and 19). I set them all to 19 1/8th...

I have access to some manometers at work. My question is can I use four individual manometers to do a cab sync and get it real close? We have single manometers at work to check gas pressure on furnaces.

Need to sync carbs whats a good sync tool and who sells them at a good price?

So I bought the synchronizer below. I got it hooked up, started the bike...and the needles jump all over the place. Impossible to do anything with this. I did some searching and found a couple old vids of guys using this and having to run the bike at 4k to smooth the guage out enough to us...

Been fighting a hanging idle for quite awhile on this bike, the other day, after a water pump rebuild and float level check it started 'hunting' for idle....would idle smoothly for a minute or so, then jump to 2100 for 15 - 20 seconds and drop back to idle. A guy on the XJ forum said it was a...
