Sanity check need for valve specs (Now Belts! 2/1)

[ducpainter]

The 5 mm allen key method doesn't work for a 1K DS engine. Your belts are way too loose.

Do a search for belt tension

I did a couple of searches and found mention of using a 3mm to check.

Couple of questions though:
1.) Is that right? Do you do the same check with 3mm instead of 5mm?
2.) Why are the 1000DS belts spec'd to run so much tighter?
3.) Do all of these take into account the change to loosen the belt tension that happened a while back?

The reason why I as is, I had my belts adjusted at the dealer less than 3,000 miles ago. Before I removed the belts, I checked the tension using the 5mm wrench on both cylinders and they appeared to be tensioned closer to what I have now than the tighter tolerance you are saying is needed. I have no reason to suspect my dealer from doing the work incorrectly. I talked to them about it and stood over his shoulder to see how it is done with the factory tester.

And I would still love for someone to explain how to secure the closers. Thanks everyone!

maybe your more motivated than me to write a tutorial for the DS1000 motors but.


1) you cant get both rocker arms to come off at the same time. its impossible due to the shape of the cams.
2) the 5mm trick does not work. A 3mm did work though.
3) the timing locations are different
4) you may or may not need to remove the cam to get the belt off. i found a trick of using a shim to get it out.

Thats the only differences i knew of.
