Guys, do the math correctly. Working it out mathematically and a DS with stock CDI hitting limiter around 7200 RPM will get 72.7 miles per hour with 15/40 and 22" tyres. Lets assume those 22" tyres grow a little to 23", which the do at high speed, and you can get up to 76 miles per hour before you hit the limiter.
With a CDI that will allow you to reach 7700 RPM you will hit limiter around 78 miles per hour, 81 miles per hour with tyres growing to 23 inches.

A well tuned 2001 DS650 with a 275lbs fat *** on-board will hit the Rev-limiter at 72mph , 75ft before the lights in a 1/8 mile drag strip.

it very possible your jetting is way rich and that is why your DS wont pull top gear.
Bigger.

BiggerisBetter that was a thought i had also so i checked my plugs dark tan and dry.
For the majority of the time that i have owned it it has been rich and wet plugs.
A friend of mine loaned me a compression tester but it didnt have the right size.
Anybody know what size fitting i need.
I did use a gearing calculater and it said at 6500 where i think i was at i should of been
doing about 68 so im not that far off.
