rpm

just curious what would cause a surging while holding a steady throttle in the 1500-2500 rpm range. example would be cruising down a neighborhood street. it will be smooth for a bit but then start surging. to the point i sometimes have to pull the clutch in and blip the throttle for it to stop...

:ummm: I would like to thank everyone for guiding me to this point, but I still need carb help. Have an 07 Max with 2K on the clock. Everything is stock except for the below listed mods. I noticed after I installed the exhaust and air filter that it seemed to be running lean around 4K or so...

Mains changed to 147.5 today. Still stumbles badly at 5500 rpm. Low end power is awesome and after about 8 seconds of stumbling, I am able to nurse it into the higher rpms then...hold on!!! 115 mph when I shut it down (got scared and ran out of room). V-boost is still disconnected and in the...

Ok, here it goes. I have been rebuilding a 1986 Vmax which sat for approximately 8 years. I know the previous owner and have good knowledge of what has been done to the bike. I have redone almost everything at this point and have been working on it for over a year. When the bike was originally...

just a random question but i'm in the market of a vmax or sabre and i know the v65's are around 3800rpm @ 60-65. how about the maxes? i know coolness wise the max wins no questions asked but i like to do some long distance riding and rarely do interstate unless i have to. any input?

does anbody out there have this setup. evad

Ok folks I figured out my high idle and I still am having a high speed miss. I have ruled out anything in the carbs and my synch is good to go. The bike runs like a freight train until 6-7k rpms and then misses all over the place until redline. I have yellow spark plug wires and have...

I have just bought a 86 Vmax. It was sitting for 2 years. It has 12,000 miles. It is stock except for a k&n air filter. The carbs were overflowing fuel out of the vents when I first tried to start it. I took the carbs apart, inspected & cleaned them. checked float level: level is correct (I have...

Ok - what is the proper rpm to sync you carbs at - i have heard from 800 -- 2000 rpms - what is it?

WHILE CRUISING AT 25 MPH, OR SAY 35 MPH FOR EXTENDED PERIODS OF TIME WHAT DOES EVERYONE KEEP THERE RPM'S AT OR ABOVE ? AT 35 MPH IN 5TH GEAR THE BIKE LUGS ! SO YOU HAVE TO BE IN FOURTH GEAR OR MAYBE EVEN 3RD GEAR THIS IS WHY I'M ASKING ! THERES A LOT OF TRAFFIC HERE AT THE JERSEY SHORE , AND ITS...

So I've been doing this and that for my carbs. Noticed the front left was cold, so cleaned the heck out of it with shotgun and peashooter and its running from the start now. bike idles high (has since i got her a few months back) at 1400 rpm or so till it gets nice and warm where she wants...

Just got the carbs back on yesterday, synced them today, and tried to adjust the air/fuel mixture screw. The bike starts fine, idles fine, but I loose all power above 3500-4000rpm. like its hesitating, not enough fuel ? I have the air/fuel screws out at 5turns, which seems alot, but anything...

I bought a 1985 VMax that came with 4 K&N filters on the carbs, no airbox. I Dyno'd the bike and was shocked at the 80 RWHP. If I go full throttle in any gear, below 4500 RPM, the bike breaks up, all the way through top end. If I go full throttle above 4500RPM in any gear, the bike runs great...
