Some good advice on the posts here. I put a set of intake rubbers on my sons fazer, they cost about £75 for the set from Buster Accessories. Even though the originals were badly cracked and deep none of the cracks appeared to go all the way through, but the vacuum take off plugs were shot (as Fazerider also said in his post) and that was most likely causing the rough running.
When I went to remove the vacuum take off plugs the tops came away even though they looked ok. I replaced with new Yamaha ones and they cost £10 for 4 including delivery
As I had the carburettors off I opened them and cleaned them out and checked the Diaphragms. Put it back together warmed it up and balanced them. Compete job took me 3 hours.
If you take on the cam chain at a later stage get some experienced assistance when joining the chain as failure of the split link would do some serious damage.
The cam chain on my own Fazer was 1.5 links longer than the replacement when I finally changed it. I was stopped in traffic a few days before I changed it and a friend 2 cars back could hear the rattle above the traffic. Most amazing thing was that the Fazer still ran well even though the cam shaft timing out by a tooth and a half with the worn chain.
