Dalton DBO800R kit upgrade with new Y/B secondary spring?

creed · #1 01-23-2012, 09:57 AM

I bought a DBO800R clutch kit and primary spring (green/yellow) already installed in the primary clutch from a friend of mine. I took off my primary clutch and spring and install his with weights / rivets and spring this past weekend. I do mostly mud riding and have 27" 589's righ now but will be upgrading to the new OL's here in the next few months. I am thinking of ordering / installing a Dalton secondary spring (yellow/black). What can I expect in performace and will this new set up be comparable to the DBO800M kit?

The only difference in the two kits is the secondary spring.

Do you know what I can expect from adding the secondary spring?

Little more belt pinch, so a little more RPM, you will have to try it and see if it works the way it is, you may have to add weight to the primary weights or not, depends where it shifts.

The addition of the secondary spring requires a slightly different "set up" of the flyweights as well and sometimes a few different rivets, depending on your situation.

The DBO800M kit is the proper calibration for your machine and is better suited to help compensate for the losses and calibrate better for the intended use with the tires you plan to install.

For more info email any time to info@daltonindustries.com

you can go to the dalton website Dalton Industries Ltd. and go to the "downloads" page and see the complete instructions and set up guide for your application...there are some variables in there that only you can answer, then you set up according to that guide.

Have you researched about a 650 Helix in an 800?

There is good info about that within that download of instructions. More than I can type here quickly.
In general on smaller tire bikes and typical mixed trail use I do not prefer it at all.

Here is some good reading from Dalton, with a good description of the 650 helix and how it works;

I just installed the Y/B Secondary... I love it!

It's back shifts faster, so I use the brakes less and when I hit the throttle again it's in a "lower gear" so it wants to do back flips when I get back on it!

I'm running a Tan Primary spring aswell and I like this spring alot more than the G/Y, but changing primary springs did require weight modification to raise my shift-out a bit.

I couldn't be happier with this setup it's Perfect in my book!

Glad it is working out the way you like it.

People also need to consider that cvt clutch calibration has some personal preference involved. Primary springs are a great example of that, thus we have so many. The Green /yellow is by far the most popular (thus it is the one in the kit), but not everybody out there is the same.

The other thing that is a "feel" thing that some like is RPM. There are some out there that love the sound and feel of rpm....I've had PLENTY of times where someone who likes to experiment (lust like me) with their bike...and they SWEAR it is faster when it is revving higher than where it is supposed to (to over rev drops off hp worse than under-rev)....and plenty of time they have even come over and we have had multiple bikes , and equipment on our test track and prove without doubt that upshifting the bike a little quicker and lowering rpm makes it faster....they still like the feel of what they "feel" faster....and that is fine. You gotta love you bike !

There are others out there that want to LOWER it...they do not want rpm in mid-range cruising...they want to add too much weight and lower the rpms way down...but they may not realize that it hurts the back shift so badly (the ability to hold rpm on its own under load) ...that the belt will be in the wrong ratio at the wrong time and thus cause slippage. (imagine if you climbed a long hill on a 10 speed bicycle and could not shift the chain up to the big sprocket on the rear ....on this thing that will cause slippage in the front).

There are more out there that have inefficiency and do not know it because they use too heavy springs for the application and have it in their head to rev too high (up where there is less torque and hp)....but there is everything in between.

We give good info in our model specific Can Am specific questions on the FAQ page of our site, regarding the components .

as well as the Can am page.

But the important thing is that flyweight/rpm is adjustable, the optional springs are sometimes case specific, sometimes options, and sometimes personal preference. You can always test and tune to find what makes you happy.

PS,(since I'm on here) it is worth noting that owners of Can am 1000 models should never refer to the question - "how does that primary spring act?" - with owners of 800 models.....they act very differently. The stock primary spring that engages at 1750-1800 in a 1000 would seem like a high engaging spring in a 800, ...and the tan would engage the clutch at idle on a 1000....it is not relative, and sometime the owners of 800's have ill advised some owners of 1000's, etc. because they may not be familiar with that.
- just saying this because we get similar questions often, and it may help inform some.

Happy tuning ! ...not all are the same and it is nice to have some options.
