Gears 1 thru 4 seem fine but when I get into 5th gear and try to accelerate it seems to be slipping, If I'm at around 45mph and start to accelerate 5th will start winding and accelerate very slowly. If cruise is on and I'm going up a hill it will kick out the cruisse and I need to downshift. Any thoughts are appreciated.

03 RSV 16K miles in my favorite color. Need a larger garage now. Love the sound of the RK pipes and the mechanical harmony. Feels and Sounds like driving a 70 Chevelle SS454. It doesn't accelerate like the MkII but the wife likes the ride much better and the more relaxed feel doesn't encourage me to do as many banzai runs. Will keep me in better standing with LEO.

When I was a lad I had a neighbor who had a first gen Venture, I loved that bike and told myself that someday I would have one. 24 years later I found and bought my Venture from a BMW dealer who had it stored in his garage in pristine (honestly like new) condition with an original 8500 miles on it, it was his personal bike before he got into BMW's and I cannot stress just how nice it is, but was it ever dusty! I drove it the 60 miles home and it purred like a kitten, shifted beautifully, wandered a bit on the highway (25lbs air in both front and back tires, who thinks to check that? oops) Anyway! I decided to take all the plastic off the bike, clean, polish, touch-up, change the battery, oil, filters, plugs, wires etc etc... I spent an entire week, dawn to dusk on that bike, and when I was done, whoa! It looked like it just came off the showroom floor and I was very pleased, right up until I rode it. Before I describe the problem, I wish to point out that I am not a mechanic, on a knowledge scale of 1 to 10 (ten being a pro mechanic) I am about a 3, when it comes to electrical, I am more like an 8 or 9. The problem: Ok, choke the engine and start, it fires before 2 revs, warm up engine and turn off choke. Hop on and and begin to ride, acceleration is very smooth, here is where the "issue" starts. Ok, as you accelerate to say 55mph, you go thru the gears and you reach that 55mph, at the very moment that you reach your speed you let off ever so slightly on the throttle and you feel the inertia of the bike meet the declining engine RPM, in other words you are no longer accelerating and you are not slowing either, it is at that very moment that the engine begins to bog or act as if it is starving for air or gas or spark or???? It continues to go down the road, only once has it backfired, one pop while moving out to pass a car. When I accelerate from the 55mph, there is a 1/2 second delay in throttle response, and for just a moment it seems to "chug" up to speed then accelerate smoothly and normally. Saturday night on the way home from work I tried an experiment, I had driven about 10 miles so engine was fully warm, I would accelerate and experience the above, so I cut in about 1/4" of the choke lever and it accelerated very smooth! It did not "cure" the problem, but made it 75% better.. With the exception of new plugs (I believe I gapped them properly) and wires, battery, oil and filters, I didn't even touch the engine or carbs, but maybe I dislodged a hose, or??? I don't know, I don't "see" anything out of the norm but this is making me crazy! PLEASE, if you have a suggestion or have experienced similar, I can sure use your advice. Thank you muchly!

Hey y'all. My 2000 MMLTD (41,000 miles) accelerates just like it should under hard throttle going up through the gears. Seems to run great then. However, it vibrates (misfires?) when I try to accelerate at higway speeds like 50, 60,70, etc.. Acts somewhat like if you tried to accelerate in 5th gear running 20 mph. Shakes. I checked thoroughly and really don't believe it is anything in the drive train like the middle drive gear bearing or anything in the shaft or rear diff. From what I see using my timing light, I think my front two coils, wires, plug caps, whatever are the culprit. Took them out (such a pain) and did the resistance test on each item. All checked well within tolerance. Carbs are synched up perfectly. I've been wrenching for 37 years and am looking for the simple. Don't want to buy coils if not needed. Any body had any wires or wire insulation failures. Any ideas? Thanks. Rusty

My 86 Venture Royale has been tuned up and the dealer balanced the carbs. It seems to accelerate very well but dies off quickly as it approaches 90 mph. The maximum speed is about 95 mph. I ran cleaner through the engine which improved the acceleration but still no top end. Can defective carburetor diaphragms allow the bike to run smoothly, accelerate well but have no top end? Any suggestions would be appreciated.
