Solved.
I have been looking at my tank with the chipping paint.
Also looking at the bike overall.
Took the seat off to do a good cleaning.
On the seat post I noticed a rubber grommet.
It is identical to the grommet I found in the airbox.
I guess Triumph sent me a spare part.
Now I would be really happy if I knew what to do about the chipping paint.
I e-mailed BellaCourse.
Michael replied that the Monza cap would not fit a Speedmaster.
Anybody know what paint or anything I could use for the rim of the tank?
Dealer said clear nail polish,didnt work.
Tried enamel,didnt hold up.
Any suggestions would be appreciated.
