backfiring

I hope this is an easy fix, I just went through the clutch and got it on the road now I'm getting multiple backfiring issues does not do it on idle only after riding about 10 minutes ... any thoughts

I have a 2005 Vmax with 15k miles on it. When I rev above 2500 rpm intermittent backfiring occurs thru all 4 carbs. If I let out the air/fuel mixture screw 6 times it will stop on all but one carb. I know that that is way too many turns and indicated an air leak somewhere. I have used two...

I bought a 2005 Max in great condition a few weeks ago and when I picked it up it ran fine with the exception of one of the carbs backfiring on occasion. I installed an Ignitec computer and COP's kit and while the bike became more responsive it would still backfire thru the one carb. Now after...

Hey all, so here is my dilemma.... I'm hearing my 1994 "POP" through the exhaust on the left side when running about 4500 RPM constant. I ended up parking the bike on empty about a month ago, like a dumbass!! Always top off when you park if you can. So I get her out tonight, and the fuel light...

Hi Our 88 Vmax hasnt been run for probably over 5 years. We have completely overhauled it. It is now just about done. I am trying to tune and sync the carbs but i just cant get it to run smooth. I have gotten the vacuum's very close but still it dosnt sound right and it back fires like crazy...

Hello everybody. Got a new 2005 LE VMax gen1 (3000kms) last July. I could not be happier. Winter is much longer this year, like forever. Fantastic ride. Anyhow.... The only puzzle I have is trying to figure out what could cause the motor to backfire when I blip the gaz slow down when matching...

Backfiring popping thru exhaust at idle. Running Mikunis with a new motor, 1540cc, 13:1 compression with the .380 cams, dyna 3000 set at stock curve. I have a handle on how to get the top end and midrange right. Issue I'm having is that it is backfiring thru the exhaust at idle. I've...

How do I stop My VMax from backfiring? when I try to start the bike, the bike will not start. Cleaned the carbs twice (jets, diaphragm), drained the tank and bowls. I can start the bike with using a starting fluid, but have to keep the rpms up high and with a consistent backfiring and will not...

Hello everybody. I just got (June 19th, Fathers day no less) my second hand-me-down bike from my dad The first was a 1982 Virago 750 and now...... A 1985 V-max! Only real downside is that it has 56,000 miles, eek! Well last spring he was thinking of giving it to me and when he fired it up he...

I have 98 that just hit 29000. I have a feeling it is less than as powerful as it should be (who knows? It's my first motorcycle and I've only put about 200 miles on it). I was riding with my friend who has an 87 Magna 700 and he seemed to keep up with me, though I probably never had it above...

have just fitted an alarm to my bike (and apparently voiding the warranty at the same time but hey) and it started miss firing. what have i done wrong here? i followed all the wiring diagrams and am not new at wiring i dunno how this is happening any ideas? (wires r connected to battery, earth...

I have a 97 Vmax with the stock TCI. I got some COP's from ebay from a 2004 gsxr. I decided to use the facory harness so I wired it up the the COP's harness' with the red/white wire hook up to the right side wire on the COP. I installed the back two coils no problem, fired it up and ran fine...

mu bike was running good. 2 days now only my left exhaust keeps backfiring constantly... it is getting a little annoying in the center town. no matter how many rpm i have when i release the throttle ... bam boom bam bam. in the night you can see sometimes and a little flame only in the left...

Rode my bike 35 miles this morning (4:15am) to work and the bike was just getting off the cold C mark when I arrived. Very sluggish ride and when I had her up in neutral and reved her without the choke, she backfired and saw some blue flames out of the exhaust. I checked my plugs yesterday and...

my bike started backfiring after i had a diaphram go out. i replaced the part but its still running bad. it will ride fine then start backfiring and bucking. if i turn the ignition off and then restart it goes away for a while. what could possiblely be the problem?

Hey all: New member here with an '89 Max. I'm working on resolving the backfiring issues with my UFO 4-1 exhaust, and with the help of this forum, I'll get it done, but....in the meantime I live in a real quite neighborhood and the backfiring drives the neighbors crazy! What can I do to...

so i took the bike out yesterday and had some issues at the initial startup. bike started fine and seemed to be running alright for about 5-7 minutes while i geared up to leave. this is pretty much the normal procedure as i make it a point not to just start the bike and immediately drive off...

So I finally got the carbs on the bike this afternoon and had to fire her up. What a difference, nice idle, no backfiring issues as before, and numbe one carb diaphram is no longer fluttering back and forth as it was previously. Just for informational purposes, I bought this bike with 4,800...

I just bought an 07 VMAX with only 1000 miles, so it probably didn't get ridden too often. I didn't see any other posts that had all these specific issues. Issues; 1. When warm, as soon as it fires up, it immediately jumps to 4K rpms and stays there for quite a while. Sometimes it comes...

just got a 95 vmax with kerker slip-ons. seems to run pretty good. battery is weak, carbueration seems pretty good, but it seems to be backfiring pretty often during decelleration. any suggestions would be appreciated.
