rpm

So, I'm a brand new European member but I've roamed around this forum and still I'm unable to fix my bike: I've bought an cursed 85 restricted French Vmax, site unseen, and worst of all, sent a buddy of mine to check and bring the bike (since he was a veteran rider and I've assumed he would...

Just picked up a 2011. Bike has V&H CS-1 exhaust, power commander V, K&N filter & I'm assuming the airbox does not have the restrictor because it was in the power commander box with other items. The previous owner had it dyno'd & there is a dip in afr early in the rev range that I'm betting...

Hello, Last year I'd install Ignitech TCIP4 v88 module on my Vmax. I'm wondering how high rpm is safe for my engine. Now rpm limit is 10200 rmp. What do you think about it?

Hello all, Well I finally started to troubleshoot my 85' Max (29,000 miles) and could use some advice. It was great a year ago when I bought it, now it gradually got to this point. Bike is completely stock except drilled muffs. It hesitates at WOT. (when i'm expecting the boost to kick in...

Been riding around and found a slight but really annoying squeeking noise riding at 3000 rpm. Doesn't matter what gear. Anyone have this? Thanks!

Hi Guys, I am new to this forum and bought a 2000 vmax 1200 in may. Have already done some modifications and I am currently adding a digital speedo with tach. I am trying to locate the “Tach Output” or “RPM Signal Output” on the max for the Signal input for the new digital speedo with...

Torn down carbs,ultra sonic cleaned, flushed out everything with carb cleaner(about 2 cans worth), installed carbs. On start up the rpms are off the chart. Tried backing sync screws all the way in, all the way out, idle adjuster backed all the way out, all to no avail. My floats are just fine...

Hey All, I wonder if I could get a favor from someone running OEM wheels and stock tire sizes? The next time you go out for a ride, would you take note of the RPMs at 60mph (indicated), and also at 70mph, and post them up for me? Just curious about this since I don't have OEM wheels or stock...

I ran out of gas with my max yesterday (not too uncommon) but after I started it up again it seemed as though I didn't get much power past 5k rpm or half throttle, and when I go over I hear alot of popping but no power. With lower throttle and lower rpm I get the same amount of power and torque...

When I throttle over 1/4 to 1/3 and the bike is under 2500 rpm it will stumble and almost make a tst tst tst sound while giving zero power beyond the amount it starts to stumble at. I've also noticed that it will do the tst tst sound when i go past about 1/3 choke. Any idea what it could be?

Hi everybody, I went for a ride this morning and then stopped the bike for about 15 min. Everything was fine. When I wanted to drive back home, I could not accelerate past 4k rpm. The bike was accelerating just fine below that rpm but then at 4k she felt like she was struggling, unable to go...

Hi, I am a new vmax owner from Sweden. Sorry if my English is not perfekt! I bought the bike a week ago and it run perfekt on the 200km I drove it home. It was a dream! The best bike I ever ridden! When I got home I cleaned the air filters because they looked really dirty and the crankcase...

I recently bought an 88 with a stage 7 jet kit and 4 into 1 kerker. It sounds good, but I think it is lacking power, especially at 7,000 rpm. It accelerates smoothly until 6,500 then it will hesitate for half a second, pull to 7,000 and then it is like it hits a rev limiter--no more power. I...

Strange noise in low rpm (solved) Hi guys, since today my vmax 1200 '97 speaks some strange noise on low rpm (900-1100). First squeaking noise comes out between front and right cylinders under the carbs.When I add some throttle noise goes away. Similar kind of noise also on low rpm comes...

I have a noise I believe is coming from the carb/air filter area but only at around 1500 rpm. For lack of a better way to describe it, it sounds like a large solenoid clacking away. I know there is a servo for the VBoost and mine seems to cycle fine on start up but is there a solenoid or...

New guy, probably old question. 2004 max, all stock except supertrapp slip-ons. Carbs rebuilt, valves adjusted a few months ago. Anyways, I noticed when running down the road at low rpm if I gas it, it cuts out till the rpms come up. Don't have any idle, or starting issues, but have also...

This is a spin-off of my thread about jet size with the UFO 4-2 exhaust. http://www.vmaxforum.net/showthread.php?t=34504 My Vmax is an '03 with almost 19K miles on it. I got it a couple hundred miles ago from a previous owner who hadn't ridden it much in the past year. It's got the UFO...

I've been fighting with a rough idle for a long time and read all the posts about this on the forum. When the bike gets past the "normal" operating temp...close to the red but never overheating it would run rough and sometimes stall at lights and intersections...not good or safe! I received...

There seems to be some pretty good evidence that running COP's without resistors on the earlier model VMax's can result in a change in the boost opening rpm from 6K ± to around 7500. I and a couple others have noticed this....anyone else?
