(SOLVED) Rich Running & Fouling Spark Plugs FIX | Yamaha Virago Bobber | So Simple I Feel Dumb!

- In this video I FINALLY solve the rich running condition on my 88 Yamaha Virago bobber project! The fix was so simple I almost feel dumb for not thinking of it before. I pull the carbs and go through them for what feels like the hundredth time, balance and tune the carbs in, and show some before and afters of the fix and how it runs. I got sick part way through filming this, so it was shot over the course of about a month and a half, but I'm feeling close to 100% now! I also show examples of the bike dropping a cylinder, and cranking but not starting, due to spark plug issues. Thanks for watching, and I hope this info helps!!

Glad to FINALLY have this thing fixed! Now I can put some actual time and money into it! What do you want to see next?
Glad you solved the issue..I had the same problem with my 04 Honda Running Rich, I rebuilt the carb,new air filter & new manual choke enrichner.. Even a new battery now everything Runs smooth
Nice!
I had the same problem with my virago-1100 , and my TR1 XV1000 Roadster (chain not shaft, slightly bigger than your RJ, RH ? model 81-2) I went to iridium-plugs , one heat-range higher on rear-plug and disconnected the rev-counter (early-models pulled the 'signal' off the rear-pot ) . Only thing that really-cures them is ignitech or equivalent ign-module and different carbs or single-carb-conversion . Used to be a USA-made ignition that run off the r/h-side cam , could be 2nd-hand-ones over your-way maybe. Only expensive options in my part of the World . Dave NZ
Those carbs really are a massive pain
For sure. For what SHOULD be a simple setup, they made it way to difficult!
That is the sweetest Virago bobber Iv'e seen yet.
Thanks!
I just bought a 1997 1100 that has not ran in 5 years. Cleaned the carbs and here I am...searching why it runs rich lol. Props to you man...taking those carbs in and out sux! I am definitely going to check those o-rings!!!
Lol thanks. Yeah I have been messing with those carbs FOREVER! Good luck with yours!
@@EvanWells07 Thanks! I will kep ya informed as to what I find
Awesome!
Glad you got it solved. Communities are the lifeblood of sharing pain, tears and hopefully solutions for what keeps us up at night. Happy Belated birthday and sucks about you getting the Rona. Hope you're back to full strength soon. Cheers!
Yep I'm back about 99% at this point, thanks! It was great to find the info kind of at random on the FB group. He posted it hoping to help out others, I'm just passing it along hoping to help even more! Thanks for watching!
Congratulations now just relax and driving nice and easy.
That's the plan! I still have more I want to do to the bike, but didn't want to waste the time and money until I had the running issue fixed.
Im glad you have this fixed and running i worked on mine all day just realized yours is a 1100 mine is a 750 but same issues i have mine running as good as i can i think i need a new petcock but I rebuilt mine amd it’s as good as i can get it untill my mechanic buddy looks it over. I keep dropping a cylinder but well see if its a coil thanks for this vid!!
You can hear towards the end of the video where mine is dropping a cylinder. I replaced coils and plug wires, all to find out it was spark plugs every time. They were fouling out so fast at first I thought there was no way it was just the plugs. It was so rich I would only get a few minutes of riding.
@@EvanWells07hey I have a 81 xs 400 Yamaha and it does the same thing it runs a while but then it dies and I think a cylinder stops working and dies, the spark plugs are new though, what could it be
I know you feel great after that night mare 😂..I like you video.
Be happy thank you
Thanks! Yeah it felt pretty good to finally figure it out!
I've had and have a few of these including TR1-chain-drive. Early ones took rev-counter signal off the rear-plug , I disconnect it , run 1x hotter-plug on rear (Iridium) , replace or dismanle and clean the plug-caps , big-improvement , enough to make clutch-slip ! Remove ALL kill-switches out of the system: clutch /sidestand . Replace or dismantle/clean ign-switch and h/bar kill-switch . Run heavier-cable to starter and a separate earth-cable to starter where it bolts-on . Clean all 'Earths' and check battery-cables for dry-solder bad-connections . The 'Later' igniter-box's that are compatible are better . Check fuel-cap vents are allowing enough 'flow' , sometimes 'indexing' the spark-plugs helps also . Rear main -jet (factory) is larger to run-richer and aid cooling , check this before raising plug-temps . Dave NZ
I have went through a lot of that stuff before I was making videos. I appreciate all the info though for sure! Sounds like you have been way deeper into these than I have!
@@EvanWells07 It never-ends ! The bearing-cam upgrade is cheap, easy and worth it as-well . They Will eventually fail without this mod . Makes them go a little-faster again , so , win-win . Riding (air-therapy) keeps me sane though , plus I'm too-old and broke to buy a 'flash' bike . I see that you have some cool-vehicles too , old-stuff is very expensive in New Zealand these-days , even rough projects cost thousands . Dave
Luckily the old stuff here is still reasonable, but slowly getting up there. We have enough modern engines to swap in, or older ones that no one wants, that all of that is still pretty cheap. I've always like bikes, and rode, just never had the desire to buy one. This was given to me by a friend who had it in pieces at the time and was fed up with it. I do enjoy the challenge of learning new stuff though, so I was more than happy to give it a go!
@@EvanWells07 Well Bro , you certainly brought it back to life ! and you inspire people by dealing with carbs which can be a nightmare . Love the fire-works too . Dave
Thanks! If anything that is the goal, to show people what I do know or have learned, and show that anyone can do it!
Well done man! Glad to see it up and running right for ya. Now, go get some two wheel therapy!
Thank you sir. It will be nice to ride more than a mile or two between plugs.
23.41pm still on the go..got the carbs out..ffs hahaha stripped one side its completely full of crap mikuni carbs wish I never started this now...I don't know what to clean first of course been watching your videos along the way I've also found a broken bolt in the ceilinder head on one of the carbs rubber colore ffs..hmmm....Time for a coffee ☕️ & cig ...bloody bikes anyway I know how you feel note mate 👍🤪🤣....just nicked my Mrs spare toothbrush 🪥....oh lovely that will clean my carb..lovely hahaha
Lol it's hard to understand until you have done them, but I had days / weeks / months in making those videos. They are such a pain! Wish I would have switched to a single carb years ago, but it felt like a personal challenge to make them work at all costs! Good luck! You will get there!
My 82 is all stock, garage find sitting for years, I got it going and riding well, all except the front cylinder sputters on take off or even partial throttle, all new plugs, cleaned etc, you name it I’ve done it, except the o ring……. I hate messing with the carbs… 😢I didn’t see the ring lol
Nice! If it's just sputtering, it may not be the o-rings but still worth checking. Have you balanced the carbs?
Yes I totally understand we do these things because there hard if it was easy we wouldn't do it..but it's what us men do my Mrs said to me how do I remember where it all goes to...I said I don't hahaha
I'm doing mine at the moment in the shed..its starting to do my head in now..watching your video it's like me here..I've got to get the carbs out I think grrrr bloody thing it was OK a few days ago but won't start now got sparks got fuel just done oil change filter it's a xv 750cc virago I've chopped the back off single seat now new headlight with skull led light back I've got 2 lights it looks like spiders eyes anyway there's no paint on it all stripped down to metal..I don't know what's wrong with now back firing a bit and it came out the carbs puffing became it's not sat Wright so it blew it around the rubber I think I'm going to get the carbs off....ah bollocks hahaha
Nice! I have a few other videos on the bike as well explaining how I did most of the stuff, and also some more tuning stuff if that helps or gives you ideas! Sounds like a cool build so far. Good luck with the rest of it!
@@EvanWells07
Thanks boy...my Mrs said it looks like it belongs in a batman film hahaha she won't go on the back with me to scared ...she's Swedish sopost to have viking blood hahaha
@pb6972 That's why I cut my back seat off. The wife wasn't gonna ride on it anyway :)
When you say shim on the needle, was that just a washer or o ring? Thank you
They are basically washers, but very specific machined washers, or plastic ones. The thickness raises or drops the needle position based on what's needed.
@@EvanWells07 Thank you!
Hey, nice bike 😁 How did You get rid of whistle noice that viragos are known from?
Thanks! I think I know what you are talking about, and I would guess it was the exhaust. I built the exhaust before I had it running, so I never really experienced it with this bike.
Bloody carburettors..they are a total fker...to get out..still on it 10pm here now I'm also thinking how the hell will I get them back in..I worry about thar later I got get out first I've taken everything off the pipes the back bits so on..I think I just set fire to it instead😂 hahaha
Where did you put the shim on the needle side on the jet ?and what size ? I have the same problem on my bike
I've swapped it all so many times I can't honestly remember. I think I have the stock shim and one size up jets from stock.
@@EvanWells07 thanks i am waiting fore parts now I orded som new floters and som jets and other parts. I bought the bike complete stock from a old man after i made a bobber out of it and take away the original exhuast and make straight pipes the bake started to owerflow with gas an killd my sparkplugs So i guess i need to adjust my carburators like you did. Youre video helps me alot from not to give up 🤣 youre bike make the same bangs and are diong the same noise as mine.
Sorry fore the bad typing i am from sweden
@Hardearth1 good luck with the project! I have other videos covering lots of specific stuff I've done on the bike, and if you have any questions feel free to ask. I will help where I can!
Hey man my virago started puking oil out of my air box any ideas on what’s causing it and how 5o fix
I would guess it has some blow by. There are a few really good virago groups on FB that may know more about it than I do.
Is there any way you could make a copy of that Facebook page with the details about fixing those torn o-rings? I don't have a Facebook account and they won't let me search through the site to find that posting. I was hoping to make a copy to give to my buddy who is going through that flooding problem you had.
I'm not sure where I would copy it to send it to you without Facebook. You could just send him the link to the video.
Can you explain the tool to remove the slides
The tool to remove the slides? I didn't use any special tools, just a couple screw drivers and needle nose pliers I think?
the screws in the '97 1100 I just fixed are special torx security screws... and mine felt loc-tited in. Use a tiny flat head to remove the center security post if you don't have the special bit in your tool box... then use the correct torx to turn them... I suggest you warm up the carb body to make it come out easier... don't break one off like I did
Anyone: Virago 1100 1996 that dies efter driving 5 minutes!
Any idea?
Thanks!
Is the fuel pump working? Plugged filter?
That’s awesome my guy! I am having the same exact issues with my 98’ 1100 so I will be going the same route. Do you have a link to where you purchased the Orings from by chance?
I didn't have the "right" O-rings in my kit, so I just used some smaller ones that stretched a little and fit nice. If you pause on the screen shots from the FB group, he listed the correct O-rings dimensions.
Where can one get calibration settings for the TPS for 1100virago?Thanks in advance.
The TPS?
Hi buddy, I have an XV700 only my rear cylinder fires, front sparkplug fouls and is completely black but wet. What would you recommend? other yet?
Start with the basics. Make sure the carbs are in good order and all the settings are appropriate, then move on to other possibilities like ignition, or valve issues. I see lots of guys throwing coils and other ignition parts at these, when it usually is a carb issue.
@@EvanWells07 It ran fine before, I'm now thinking I might have misplaced the yets when I cleaned the carburetors... maybe the front cylinder is to lean because I might have misplaced the yets. But as said it doesn't fire, only the rear.
@@fcdevreugd9449 that may be then. They are different front and rear. Did you balanced the carbs after rebuilding them?
I have a 83 920 midnight virago. I had straight pipes made for it. I've rejetted the carbs. I've checked the diaphragms and no holes. Installed new fuel mixture screws. Iv even shimmed the diaphragm. And I cannot get rid of the popping on take off or deceleration. I've got the mixture screws turned out to the max. 6 or 7 turns. Still pops on take off and deceleration. I even tried putting tape on the air filter. It helped a little bit. But the bike cuts out at high RPMs, choking for air. Any ideas what can be done to stop the hesitation and the popping.??
Also need your help I have clean my carburetors five times on the exact same bike and it runs great for five minutes and goes right back to missing on the front cylinder
Are you fouling plugs?
