• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Best pipe for the 630!

Off topic question....why do dirt bikes always use spoked wheels? I figured there is some kind of advantage for dirt bikes? Stronger, maybe?
 
Also they're stronger laterally than one-piece wheels of similar weight, and unlike streetbikes, dirtbike wheels see a lot of odd loadings
 
I've just got a Titanium mufflers with carbon end caps from WINGS. The sound is awesome, they are also over 50% lighter and much cooler (no cat).
The finish is first grade and the design- as they were made specialy for my bike.
See for yourself.

Something to remember if you put the leo vince system on your bike.

Today my bike is in for first service. The dealer called me asking if I adjusted the chain because he said it was "a little tight." I told him no, that the last time the chain was adjusted was when they repaired my flat. I guess he thought "this guy is a dumbass, I gotta tell him not to make his chain so tight." But when I said I hadn't touched it he sounded confused.

Well I figure what probably happened is that when I took off the heavy stock exhaust and replaced it with the leo, the back end raised up higher. I didn't adjust my preload when I was done so remember to adjust your rear preload when you're done so your chain isn't too tight!

Actually on this bike the chain is tighter when more weight is on the back. I hope I understood your post right :D

Looks good :thumbsup:the Wings are nice, I put a set on my KTM last year. Can you post a side shot to show how they connect? How much were they?
Thanks

Well then if your chain is too loose don't bother adjusting it, order another pizza and crack open a beer!

chain tension should be measured when the swingarm is perpendicular to the motor. its all about the circles...

put another way... chain is tightest when you can draw a straight line through the countershaft, swingarm pivot and axle.... or buy a 511 where the pivot and countershaft are concentric and the chain tension stays the same throughout the arc.

A tiedown strap can be handy for holding the swingarm in position.

To get at those screws I loosened the radiators first to try to move them out of the way. Didn't help.
I was going to cut an allen wrench but then I found something better (see photo)

It was about 6 bucks (5mm size) at lowes but I guess craftsman makes them too if there isn't a lowe's near you. I don't know if I still would've had to loosen the radiators, but it made working on those screws as easy as pie!

So yeah all you future leo vince system owners, buy that tool before you attempt to install your new system!

I finally gave-in and ordered a full Leo Vince system for my SM630. It should arrive within the next few days.

So I went ahead and pulled off the stock exhaust tonight. Thanks for the tip on the ball hex wrench! Still, the header bolt directly behind the frame was a real pain to get out.

My question is...Does the Leo exhaust system come with replacement header bolts? The ones that I pulled out have slight imperfections and probably shouldn't be reused.

Has anyone switched to flange head hex bolts? I'm thinking they might be easier to install...???
 
mine Leo system did not come with new bolts for the head. don't know about the hex bolts

Do you have a JD power surge?

When I installed the leo it definitely helped performance but I did have a torque dip after installing it. Fixed it with the power surge.

What type of fuel mapping was on the power surge and how did you adjust it to cure the torque dip?
