lots of places to leak , not just core plugs
moved you from cars to MC
rad leaks
cap leaks, bad cap (seal inside split)
head gasket bad.
see Antifreeze in the oil? seen on dip stick or engine oil turns to milk.
or chocolate milk? oops
leaks to ground hot, testing parked see it leak with eyes,
12 to 15 psi pressure will be clear as day leaking if seen to ground.
find where it leaks to first, then what is leaking next.
compression tests.
or rad leak down pressure testing tool.
ask a shop to diagnose it/
not running Antifreeze per the manual?
Question edited to add maker.
Question moved to sub-category.
It appears that it has a Clutch Safety Switch as well!! It must work on pressure of pulling the clutch in to start the bike (with the stand up). With the pressure spongey, the switch isn't holding.

It's that time, The final drive oil needs to be changed, quick & easy job. ... I own 2 Yamaha V-Star 650 Classic. ... thanks for the vid, i'm going to do the same thing today on my XVS ... It's SAE 80w gear oil. ... Much better than a vacuum cleaner. ... Rear EndGear oil Change 1997 Honda VT1100C2 - Duration
I see a couple for sale on Ebay ranging from $8000 to 14,0000. But those are buy it now prices. I would guess the actual sale price would be much lower. Something is only worth what someone will pay for it. Kelly Blue Book gives a value of $11,500 for a 2012
Go the venturers.org website. They have a wealth of information for Yamaha Ventures and also Tour Deluxe which is extremely similar in parts and manufacture.
u have to find out in ur book or place you bought bike from but sometime its the type of oil used that will cuz that some bikes have to have that synthated oil u HAVE to use or some bike cant have that fancy oil that would be a good place to start
seems you have no ignition, check the ignition further back eg. cable. etc. to see where you are or are not getting a strong spark, I hope this was helpful
suspect Coil, check HT high tension side of spark if none then check LT low tension side you should see a spark on the points when they open if that is working then suspect coil is defective and needs replacement. also check points setting to see they are actually opening enough and are not dirty contacts.I hope this was helpful
I think you may have blocked main jets(assuming Carbs). If your bike has been sitting for a long time this will probably be the case and they will need to be stripped and cleaned. I did have one case though where wasps had built a nest in the exhaust pipes and that is a most unlikely scenario but only takes a few seconds to have a look. Hope that helps.
This tube comes from the Air Box. If the oil level is to high in the crankcase, the PVC port, which is located in between the "V" of the two cylinders is actually vacuuming the oil right out of the crankcase, and it is collecting in the air box. When enough oil collects in the air box, ti runs down the overflow tube, and drips out behind the rear wheel. To check the oil level, put a 2X4 under the side stand, make sure the bike is level, (a helper to steady the bike is a good idea here) look at the sight glass on the lower right side of the engine, down by the water pump. The oil level should be 1/2 way up the sight glass with the engine cold, and not running. If the oil level is higher than 1/2 way up, drain some of the oil out until you can see the oil level read 1/2 way on the sight glass. These engines only take a little over 3 qts. of oil with a new filter. If you are putting in 4 qts. of oil, it is too much.Earl
The best way is to have them boiled or ultrasonic cleaned...If you can't do that, soak them in solvent overnight and use some spray carb cleaner and compressed air to clean out all the passages. I have found that a small steel guitar string works best, for the jets. Good luck, i hope this helps.
I once had a 96... these are famous for final drive whine. Try dumping the final drive oil and replace it with an approved synthetic... possibly and oil that's a bit heavier duty than stock. Usually this will help cosiderably, as long as it hasn't gone too long before a change. Hope this helps.
Backfiring is a sign of an air leak. Somehow air is being allowed into the exhaust system. If you or a previous owner has drilled out the baffles to increase sound, this could be the cause. A burned valve could contribute but is not likely unless the engine has been severely overheated. A burned valve will also cause poor performance and it can pop upon acceleration which was not mentioned in your original question so I doubt it is a valve causing the problem. Plus - these engines are pretty reliable and robust. I bet on the air leak.
Hello
Your gas tank petcock is diaphram operated.
there is a vacuum line coming off the intake, that goes straightb to the petcock.
when you turn the motor over a vacuum is created, pulling the petcock diaphram back and allowing fuel to flow to your carburetor. when you turn the motor off the vaumm is gone and the spring behind the diaphram pushes it closed and stops the fuel flow to the carbs.
Now the reason the carbs are overflowing is because the floats valves are not closing, in other words the floats are sticking.
Usually a good carb clean will cure the problem, especially for that year.
the older ones usually require new float valves/seats that are usually found in a good carb rebuild kit. You shouldn't need one.
If your really broke try tapping on the bowls of the carburetor lightly, while the engine is running, sometimes the vibration will vibrate a particle loose that may be holding open the float valve.
if it works then the fuel should stop overflowing while running.
if you know how to work on it, try this, with the engine off.
open the carburetor drain screws so that fuel will run out the carb. drain. flush out the carb.
get a container to catch the gasoline.
while fuel is flowing tap the carb bowls a few times then closed the drain screws.
clean up any spilled gasoline .
start your bike.see if they stop leaking and the floats are closing.
if it still leaks, you'll need the cleaning.
