What a niche channel but thank god. Getting an 82 virago and looking for how much work I’ll be putting into it. Thank you!

hey man. im restoring an 82 virago 750 and your video helped me alot. thanks

Thanks for this, I scored on an 85 Virago 1000 that was in storage for 16 years and am getting it dialed in!

Your a legend. Thx for sharing your knowledge.. l'm looking forward to giving it a go with my my 1994 750 Virago..qaa

Have the same problem! Just bought this motorcycle, thank you! I will try this.

Good trick for air screw setting. OR maybe backfiring is an issue with mixture control valve (pressure release)? I also noticed there is no Breather pipe given on your 81' model's front cylinder head but on rear, I have it on my front cylinder. Never understood why Breather pipe and mixture control valve both are given on front cylinder of my 82' XV750.🤔

Awesome channel dude. Thanks for the help

I will try this trick! Thanks 👍

Mine was popping because the carburetors were out of sync, do that first then adjust pilot jets .

Very helpful on my Virago '82. Regards.

Thank you very good video 🙂

Thank you for your knowledge. Please do more diy maintenance/mod videos on the Virago. Have you thought about turning it into a bobber or a cafe racer? Much love from Georgia.

Great videos! Keep it up. Where can I find a back rest like that?

Thank you for the info. And wou like to know how to adjust my floats on my 85 virago 1000

You've got a subscriber. Also I have a 1984 xv750. Good sir my bike spits pop fires when acceleration, what causes that? Thank u in advance.

Sr. Great video, I have a 87 xv750, but I have problems with backfire even when a leave it in 1000 rpm (idle) my spark plug is carbonized, might be to much gas, I wonder if this wideo could fix the problem?

Air filter change. Could use some knowledge on that.

Hello from Brooklyn - Thanks for the great video. I got a 'barn find' '82 XV750 that hadn't run in many years but only 6K on the odo - wasn't starting so it was almost free. I have been tinkering for a few months (cleaning the whole tank and fuel system and rebuilding the carbs so I can clean the bowls and jets, etc.) and she is now at least starting! Thank you so much for the idea for pilot screw adjustment with the carbs on because they are a ***** to take off and put back. One question if you have a second: the bike starts great but when its warm and I back off the choke she dies after a few seconds - is this a pilot screw adjustment fix? I am new to these Hitachi carbs, any ideas would be amazing. I am grabbing some of your merch BTW - that swag looks good!

Hi Thankyou for your video yes my xv 750 1994 us custom has had a backfire in rear cylinder carbureter .so I shall try your advice .thou I also have a persistent problem with front cylinder NOT firing eg plug is wet when removed I have removed carbs cleaned and refuted also today replaced both ignition coils and fitted iridium plugs ...but when I gun the bike for any distance front cylinder stops firing and eventually engine cuts out ...any advice be much appreciated many thanks from over hear in UK CHEERS BOB ...

From Befair, WA recently acquired 1982 920J Virago. Needle for main jet has no slots of e clip do you know if it needs some shims or what?

Ive got the same bike..i took off the exhaust middle muffler with the end pipes..leaving the main pipes still on conected to the cylinder..i wrapped the pipes in cloth put to small 50mm end pipes..went out for a drive sounds loud but ok but coming back fk me it backfired all the way home...so do i put the stock back pipes back on with the under bit muffler....or would i cure it another way....hmm thanks for your video appreciation 👍☕️😉

I just finished my rebuild and I’m running to rich. The plugs are fouled and covered in black soot, similar to yours. Is it simply a matter of turning those screws to lean out my mixture? My bike will not start or idle.

I have a virago xv750 of 1982.la I turn on and does not last on then it turns off and that I just put the new spare parts to the carburetors. some advice that you can help me solve that failure greetings from mexico

What tool arr you using to screw/unscrew? Im having a hard time with what i have om hand. The placement is not super friendly lol

I have the same bike when I get into high rpms it jumps looses power I don't know if it's air fuel or filter

Question. I just bought an 81 virago. Where there is supposed to be a flathead insert, it is just a flat piece of metal

do you have a 500 virago that you have a backfire and misfire and have a rough idle to show us how to ajust the carbs

My 750 is backfiring and as soon ss take the off the bike dies also the bike has not run for a few years any ideas?????

UMM - I think you should be working on the carb that is firing instead of the one that has the plug pulled. You can turn the Idle air screw until hell won't have it on the dead Cylinder and it will not make one iota of difference to engine speed.

My 82’ virago feels liek it’s not getting fuel when I pin it, if I give it a little gas the rpm’s will build and such but when I pin it it doesn’t jump or have any more power just the same steady build in rpm’s, what the hell is going on with my bike any idea? Last season it pulled hard now it does not

From a bike mechanic: Pops don't come from s carburetor, its unburned gas in the exhaust system. It's a rich condition.
