Great stuff, I will get that sorted later this week.

Check the routing of the cables as well, as it shouldn't do that

Yeah it's odd, noticed it last week. Is there a wiring diagram of where it should go, so I can compare?

Update, took the bike to my local bike garage in passing.

He says that there is usually quite a few vibrations/buzz around 6k rpm onward and that it is the nature of Vtwins.
He also said it is running as sweet as a nut!

Basically he had a listen for anything on toward gave it a few revs and said it sounds and feels exactly the same as another SV they currently are doing work on.

If it was crank, or anything knocking (Upper of lower) you would hear it. We have a Renault with big ends going so know what it sounds like.

The bikes pulls fine, and after the oil/filter and plug change it runs so much better.

Maybe it didn't notice, but the vibes are from 6k onwards - getting more as the rpms increase. 5k and below I don't really notice, in 1st at 3k there is a little bit more, but it evens out. The chain does need adjusting though.

Does that sound about right? I'm, a bit of a whittler!

I was going to say check your rear chain adjustment/alignment. I built a bike with a misalignment of 1/16" and it vibed like a bugger but after shimming was super smooth.

I'm going to give it a check tomorrow Blapper.

Other than that, does all of the above stuff sound about right to you?

As the bike still vibrates when stationary the rear chain etc are red herrings, I would suspect ignition / spark plugs - especially as you say it does not want to start easily.

I replaced all the sparkplugs and made sure they where in properly. The bike starts on the button every time now!

The starting issues where because of the battery.
