All I needed to do was wind the air bleed screws in a bit and make sure the TBs were balanced .... but thought I'd clean and gap the plugs first.
First thing I noticed was one of the plug caps was sat alongside its plug rather than on top of it .... not sure how that happened but I bet it's been like that for a while .....
So next thing was to take off the air box to get access to the front plugs. Once that was off I thought I'd take the opportunity to fit the early model snorkel and frame inserts to help it breathe a bit better.
Early style on left ..... Late style on right
Frame inserts: Early style on left ..... Late style on right
Snorkels: Early style on left ..... Late style on right
Swapped the right hand frame insert quite easily .... once I'd got the fairings off.
Then the fun began.
I started on the left hand side and after a lot of pushing, pulling, head scratching etc I reluctantly concluded that the left hand frame insert can't be removed without taking off the front cylinder cam cover !!!!!
Gave up at that point - it'll have to wait until I come to check my valve clearances.
So then I swapped the right one back again.
Having cleaned and gapped the plugs and stuck the airbox back on (by now it was dark) I gave up for the day and will sort out the backfiring issue tomorrow.
