popping

I am assuming its because of the wasted spark system is igniting the extra fuel in the cylinder but I could be wrong. Anybody else have issues like this. I just noticed it once it got colder out here. Only when the bike is cold, and when I have to have the choke on, after its warm it...

Hi. I've recently bought a vmax and today was the first time I've really gone any distance. It was fine whilst moving but as soon as I hit heavy traffic it started popping like hell at low revs and wouldn't hold idle. It's rarely been used for the last few years by its previous owner and needs...

Hi, When my max is cold, the front right cylinder backfires a couple of times when I drive off with the choke opened just a little. With the choke open full the popping is gone, so you would expect the cylinder runs lean. But here`s the funny bit: The spark plugs of the other three cylinders...

So i just took off my carbs last night and cleaner them, everything looked good and is now spot on, after re assembling the bike, i re synced the carbs and now when the bike idles it seems to miss fire at idle, more than usual, she seems to ride ok, but its a distinct pop and miss fire at idle...

Have had no issues with my baby, but it has set up for a couple of months and not rode. I cranked it up yesterday and noted that I had to keep the choke slightly on or it would die. When I revved the throttle it wanted to die, but when I rode it at mid rpms there was no issues. Only when I...

At almost no throttle,and i mean just barely twisting it,i get popping sounds from my air box,i know its comming from the carbs,but what could be the cause of this,the bike just had new stainless factory jets put in it by a Yamaha dealership(which in my experience) means nothing,any ideas on a...

Bike is running strong and sounds great with the HMF full exhaust. When it gets hot I get significant popping from both pipes when decelerating. A quick poke around suggests that this is not uncommon when you change exhausts, and that it results from too lean a mixture. Does that sound right...

Bike: 1992 PCW 1327cc chain drive with about 1000 miles on the motor So I just got my bike back from my mechanic. He took the carbs off and cleaned them, replaced the plugs and tuned and synced the carbs. The bike ran well at his shop when I picked it up, I brought it home, put all the...

Ok here it goes, I went over to Fargo`s place to do some work on the carbs (changed the main jets) and the bike ran great, then after a few days It started popping like firecrackers on the left side. At first I thought that it was just that the engine was cold so I let it warm up and still the...

Today was my first ride since last weekend. Last weekend I put in 162.5 mains, added a second set of shims onto the stock needles. It was getting better and better. Last thing I did was turn the a/f screws out a quarter turn each. Jump ahead one week to today Got to play with the bike and...

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...

I keep hearing about the second gear problems, but it seems like I am having the same problem in first. If I get on the throttle, it pops and jumps pretty good. Second seems to be perfectly solid. Is this just another variation of the same problem? Oh, the bike is an 86 if that makes a...

My '01 with 9300 miles sometimes hesitates and sputters upon light acceleration. At 2000 rpm and above, the bike is strong. V-boost kicks in around 6000 and the thing really hauls ass; no problem there. The dealer I bought it from and his tech says everything seems okay and Vmax's are very...

Need a little help with this please.. When my bike gets hot and i sit in traffic, i get a lot of popping. It only happens at idle, when i start moving it's fine. I have new plugs, new wires. I did the peashooter and ran 2 bottles of seafoam through the tank. Also had the carbs synched...

Gotten comfortable on the Max and started rolling a little more aggessively on the throttle... Transmission is in need of work, obviuosly, as it pops out of first when I really get on it.... What am I looking at (repair wise) and could/should I do it myself?

I have a 90 v-max with 40,000 miles it will sometimes pop out of 3rd on upshifts but not as often on downshifts. Major problem or something I can fix from the bottom? no grinding or abnormal noises at this time. any help out there? Or complete teardown?
