engine vibration
 

is engine vibration begining at say 5000 rpm's normal, esspecially in the lower gears?

Well, they all vibrate a bit. The question is, how much?

Mine starts to vibrate when I switch it on. Engines tend to.

lets just say it accelerates smoothly until i hit 5000 rpm's in first gear and then i start to get some engine vibration , in other words it "feels" like the engine is straining ..is this typical V-twin AV behavior? it does it also in second gear and so on just in the higher RPM's

Is this happening to you on small throttle openings? Open the throttle a bit further and hang on to the bars...
Mine ('99 S) does just that... on cracked throttle starts to "struggle" at 5k, open throttle, ops, we're at 10k, time to change up a gear..........

whereabouts are you ryrides? this 5krpm engine problem is obviously seriously bothering you. I would suggest you attempt to find another "known good" SV to ride to compare with yours, or ask another SV rider to take yours for a quick spin. Then any engine problems would quickly become apparent.

Alternatively, get a dealer to look at it. More expensive and probably less reliable though.

Where are you starting your acceleration from? A standard SV doesn't pull well at all below 3000rpm or thereabouts, and can lead to really bad juddering... And you don't want that, apparently it damages the bottom end.

The SV's working power band is from about 5000 to 9000 rpm, that's where it makes effective power. Anything less, and you might as well be on a 250. It certainly shouldn't be labouring at 5000, in fact it should be getting ready to take off.

What's needed is more facts. Ride it a few times right from the lowest revs it'll ride smoothly at, then accelerate at various speeds right up to 9 or 10000rpm, see what happens each time.

Also, do you have an end can or air filter fitted? That could be leaning you out at about those points, causing a loss of power- if this is the case it'll go away at higher revs.

ill try opening the throttle more and see if that helps..actually it does seem to do it more at times than others maybe i havent been paying attentionto the throttle enough...as it is..i have a good dealer that i can take it too the next town over..but thanks for all the advice folks...good riding...Ryrides

There's a harmonic frequency on mine (low mid-range, but can't tell you exactly where, RPM-wise), where for perhaps 500 rpm or so, under load, the vibes suddenly increase, then go again. Part of the character, innit?

At 5k revs the motor of the SV is just coming on song when things get really interesting. How long have you been riding? It is indeed a very odd question if you dont mind me saying?! If you dont want a touch of vibes/character then you chose the wrong bike my friend! :) Jeez if you got to 5k revs on my bike you would definitely sh*t your pants! :lol: :lol:
