The "problems" of the 660 is pretty well known, in regards to the rectifier and cush dampers, and the lean conditions. Theres pretty cheap fixes for all of it. This should be no surprise.

- Theres a "kev mod" to fic the fuelling issue (which just about and FI thumper has)
- Theres guides to fill the rectifer with dielectric grease and/or relocate it.
- Theres a guide to mod the sprocket carrier to fit a bigger bearing, making th life of the cush rubbers easier.
- You can fit polyurethane cush dampers for +40.000 miles trouble free use (with the above mod)
- Cush rubbers can be filled with spare pieces of innertubes as shims.

I know this, and I dont even own the bike.


When I think about, all the bikes I've ever had has hat some sort of "common failure point"

2000 "potential" bike isnt a lot, how many Lc4's has had rocker arm failures? How many wr250r has had fuel pump and stator failures? How many wr450f has had gearbox failures? How many transalps have had cdi box failures? How many dr650 has 3rd gear explode, how many xt600's had 5th gear failures, how many klr650 had the doohickey spring brake? How many dt125rs had headgasket issues? ect ect ect.....

Seems like someone was just unlucky, most of this could have been avoided with a couple google searces. Its a pretty common round-the-world-bike for a reason.

Good day
