Checking Valve Clearances: Proper Interval?

2059 Views 9 Replies 6 Participants Last post by  RedBird
My Haynes says at 6000 mile intervals, starting at 6000. The "Owner's Manual" says at 4000 and 8000 and then contradicts itself with a confusing "4/6000" and "8/12000" etc. page towards the back where the dealer is to stamp that the service was done.

Which is it?

Originally, the manuals for the bonneville listed the valve clearance check/adjust maintenance as every 8000 miles or 2 years whichever comes first. Sometime in '04 or early '05, Triumph "increased" the mileage intervals (time intervals remained the same) for all the twins engine maintenance schedules. The valve maintenance is now at 12000 mile intervals or 2 years whichever comes first.

For those of you with the older Triumph service manuals, just mark out the miles and change the note so the Kms readings (in parenthesis) are now the mile readings and the scheduled maintenance chart will be up to date. :-D :-D

I haven't seen a Haynes manual; however, it should have been developed after the change was made and should have the later mileage intervals.

Hey....we had almost two weeks in Nov/Dec without any bugs...but now they are back again...56 F today...55 F tomorrow with a slight chance of rain...60 F on Friday...gotta get out and get more bugs on my Parabellum. :-D
