Howdy,
I ride an 07 GV650, just got done doing a tune up, as well as a few other things. New Battery, Stator, Iridium Spark plugs, new Coils, Oil Change, and Coolant change, removed the emission regen system. Recently flushed/bled the brakes, changed the reg, Etc.
I added a K&N Airfilter, and want remove the muffler because 1, Its heavy, and 2, I want to straight pipe it. Whats a reputable site to buy new jets, and what size would I need? Also, a good rebuild kit, because if I’m going to take the carb off, may as well.
Also, The E-start button doesnt work anymore. It seems to get power, but doesnt do anything when pressed. Could that be something else down the line, or just the switch going bad?
Lastly, does anyone know that “unit” is on the wiring diagram for the horn, and where its located on the bike?

Howdy Ken!,
- What size jets are on the bike currently or are you the only owner ? (untouched original) , but either way advise us as to what size jets are on it mains and pilots
- When you press start, does the bike make any sound/buzzes ?
or do any of the lights on dash or headlight go dimm (even slightest) ? -  The horn is activated directly by the switch gear and the switch gear sends the wires to the back of the bike so that it shares the same fuse as other electrics (the main 15A fuse).
You can put a 12v meter there and see if you get any volt readings when you press the beep button on the switch gear ? - Â You may email me if interested but we do have a carb gasket rebuilt kit on the /shop/ section of the site.

- I believe I am the third owner, but I got the bike stock, so it should be the stock jets. As for what size they are, I’m not sure, but I found this.
2. I do believe the light does go slightly dim when pressing the button, but no buzzing sounds.
3. My horn works, I was just curious as to what that “unit” was on the diagram because I couldn’t find it, and had no idea what it is.
4. I will check it out, and email you if i have questions about it,
Thank you for your help.

1. Ride the bike as it is with the pipes , but make sure the DB Killer is inside the exhaust can and also fit the high flow air filter, just checking also that there is no air leaks around the engine manifolds (spray carb cleaner on them)
Ride for a little bit , check your plugs. Take pics.
Ride again after cleaning the plugs and see the colours again.
Show us we can then access how lean or rich the bike is , sometimes lifting the slide needle one notch away from the carb bowls actually helps the midrage and enriches the bike a little more.
Wish i did a tutorial for it!  (like i did for the 125cc here but principle is the same on 650cc)2. That means the starter motor should not be jammed ? – Take it off and see if it whines freely when connected to the batter directly away from the bike.
If the starter motor is OK, then consider having a quick look at the flywheel sprocket (open the casing after draining the oil first) and see if the teeth behind the flywheel have any missing , i really hope not .   I also don’t expect the “sprag clutch” that sits between the flywheel and sprocket to have any issues
I mention this because it does happen on rare occassion the starter sprocket behind the flywheel and its mini clutch to jam.
If all looks good, then it means the battery is too weak (cells inside caused voltage to drop fast) or just simply too old or too small (must be size 14BS factory size battery)
Or easy option, replace the solenoid relay , it is usually tht 90% of the time. Common part to replace on any brand big cc bike.
3. Take a picture of the mystery object đ and show us

and show us1. So it seems to have been the new Lithium Ion battery I installed, as it wasnt getting over 13.4v, put the old one in, and right to 14.5v. I did replace the front membrane on the carb, because pulling it out last time, it was badly wrinkled, but seemed strangely fine this time. Already had the new part, so may as well of put it in. I live in the desert, so Alkaline batteries dont last long here. It has brand new iridium plugs, and new coils installed last week. Thought that was the problem. It does run a bit rich showing by the old plugs.
1.5. It looks like the jets are press fit and one is screw on. What do I use to get them out, if they arent press fit? The one came out with a screw driver, but idk about the others.
2. Starting motor works, and starts no problem.
3. I cannot do that as I have no idea what it is, or where its located. Which is why I was asking if anyone here knew. lol Its just randomly there on the diagram, but cant find it.

So all good on the battery side of things now ?
Also how are the new plugs reading okay ?Mikuni Pilot Jets screw in , as well as main jets , but show us the picture of the carbs next time they are open and at least you will see the sizes for your self in there.

Considering the other old battery is still going bad, I wouldnt say all good, but the problem was resolved.
Ok, I want sure about the jets because only one looked like a screw in. Is there a special tool to get the others out?
