2007 Yamaha V-Star backfiring repair (Part 1) 

Thanks for watching. It could be something with the idle circuit or an issue with the carb flooding. I've seen videos of people bypassing the air pump. That was going to be my last resort.

@@wonkster1970 Thanks for your reply. It has the original spark plugs, so I changed them and haven’t had any more problems. So glad it was an easy fix. Love the bike.

@@mrnoedahl I'm glad to hear that you were able to fix it with a spark plug change. Enjoy. Stay safe.

Thanks!

🏆

Thanks for the info. Stay safe and thanks for watching.

Yes. The fuel line was OEM. The end of the hose was hard and kept splitting.

I'm not sure. I'll go through my footage and let you know. Thanks for watching.

I just looked. I don't have any better angles of me removing the air box tubes.

Check the spark plugs. See what their condition is. Make sure you have spark and compression.

Drain the fuel bowls on the carbs also. Maybe got some water in the gas.

@@wonkster1970 thanks for the advice .it’s started right up all I did was pull the coke out and roll the throttle a few times then turned it on and it stated up

@@janalyn06 Sounds good. You're welcome.

I'm having the same problems iv just cleaned carbs and jets had new plugs put in and still no luck

Sounds like you have a lean mixture on one of the carbs.

@@wonkster1970 That is what I was thinking.

I was still getting some popping through the pipes on decel. Not bad though. I'm working on a 2001 650 that will have the cobra pipes on it.

It was a combination of things. Spark plugs and a stuck needle in the one carb. Raw gas was being pushed into the exhaust.

@@wonkster1970 how would a stuck needle cause it. i did change my plugs, helps but still backfiring i used E3 plugs, not really a big change i thought it would be. three electrode plugs

@@ronhanish a stuck or not sealing float needle would allow an excess amount of gas to get into the cylinder while the bike is running. It would cause a rich running condition which could cause the backfire.

@@ronhanish This guy has it going on. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-eSky1ZfHdhA.html

Nice video.

What were the conditions of the spark plugs when you replace them? Were they black?

Yes they were black but not fouled out

@@josephlapadat9147 I wonder if the previous owner changed the jets in carb after putting the cobra exhaust on.

@@wonkster1970 all I know is I found a shop to check it out so I'm just waiting to hear back from them.

Okay. Let me know what they find.

Interesting. What brand plug do you use?

@@wonkster1970 Well, I have tried several spark plug brands, but I generally use NGK. Anyway, I've gotten so I just change spark plugs every spring before the riding season no matter what they look like...

@@charlieswearingen500 I use NGK also. I worked on a bike that had Champions in before. They were fouled out. I'll have to see how it starts next year.

@@wonkster1970 I use Champions in my cars and they are fine, but I never use them in my motorcycles just because they fouled out every spring riding season. I know, it's weird and it happened mostly in the Virago and V Star which is basically the same engine. So maybe it has more to do with the engine than the plugs?

@@charlieswearingen500 that's a possibility that it has something to do with the engine.

It might be the plugs. I try to run the gas out at the end of the season. My XL600R does not like stale gas. I have to drain the carb bowls if it sits too long between runs.

I touched the outside of the solenoid to ground and touched the wire to the positive side of the battery.

you can also test with a 9v battery I had to solder mine too last season

Thanks. I didn't think about using a nine volt battery.

Great work. Glad to hear it was just a choke adjustment.

Thanks for the advise. I'll do that next time. Thanks for watching!

Wow!

The customer gave me another bike in exchange for the work that I did on his bike. It probably would of cost him $300 or $400 to have the work done.

@@wonkster1970 It’s difficult to find someone to work on a motorcycle at a reasonable price around here. You did good.

I'll do some looking around.

Partzilla claims to have them in stock

4 to 6 weeks out

You try Revzilla and motosports?

Okay. I'm open to suggestions. What would you suggest?

@@wonkster1970 How about something to do with fuel line repair. Not much info on backfiring here.

The owner seemed to just ride it until it broke. I think he lived up in to coal regions of Pa. There was a lot of coal dust on it. After I fixed it, he hopped on it and drove it 2 hours home! He said it's been running great! He traded me the 2001 650 for fixing this bike.

@@wonkster1970 How about something to do with fuel line repair.

@@verdigo5892 I cut the end of the original fuel line with a set of wire cutters. It ended up just splitting when putting it back on.

So, I watched this video twice today. Besides some of the camera angles, I thought it came out pretty good. I used the Duck Bill Pliers to remove the hose clamps. Most of the time they work great on those squeeze clamps. The other pliers, that are specifically for hose clamps, work really good to remove stuck fuel lines. I could of went with some 1/4 inch or 5mm bulk fuel line. I decided to go with the OEM because of the crazy bends toward the fuel tank. I've had problems with bulk line kinking before. Braided line probably would of worked also. Anyway, thanks for your comment. Stay safe.

@@wonkster1970 Don't let people like this get under your skin. He does offer some suggestions if you can get past the condescending tone. I appreciated the video as I as am helping a friend out with his Virago.

@@cmarkchappelle7117 Thank you for watching. I appreciate constructive criticism. Most of the comments I receive are positive. I don't let the negative ones get to me. Stay safe.
