Just changed the air filter . what a major faff for such a simple job  .All the plastics dismantled and seats off before you can lift the tank . Dont want to do it again in a hurry thats for sure

Just combine the filter replacement with other jobs like : change sparkplugs and synchronise the throtlebodies
Don't forget to check the underside of the tank, mine rusted a little, so a spraycan black will do the job

My dealer told me that on the 2015+ models, the Starter Valves don't need syncing like the older model 800s and are in fact sealed so you can't. I can't confirm that as I haven't tried but I used to sync them every 4000 miles on my previous 800s and after 24k miles and no syncing, my current 800 shows no symptoms of requiring it.

I have never sync'd the throttle bodies. What symptoms should I be looking for?

Low rpm unevenness. It's one of those things that is often not noticed until the SVs are balanced, then you noticed just how bad they were. It was a perennial issue on the 98-01 VFR800 Fi's and continued with the 02-13 VFR800 Vtec's, which is the same engine that you have.

It's likely you have just grown used to the symptoms. They are quite easy to balance, as long as you have vacuum gauges and a 7mm spanner, after you have lifted the tank. There's a good guide on VFRD, or, if you don't have the right tools, meander over here and we can sort them out together!

I have the 2015 model
I did sync them, 1 was off.
Pickup on throttle is smoother now.
You can adjust 3 cylinders, one is fixed , that is your reference.
Make sure , you have a lot of fresh air when adjusting, do not do this in a closed space (garage)

Like Skids wrote, : not difficult, but a lot of work to get there.
I used the carbtune throttle balancer

My dealer was obviously talking sh*te.

I will have to get round to adjusting mine then as it's 24k miles old now.
