• 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 The previous version was outdated and no longer supported.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!

Possible clutch issue?

I bought another standard can from ebay and gutted and cut it to 3/4 length. It has made a brilliant and reasonably priced straight through can.
I think the standard can is a quality item and when modified gives really good results. Mine only weighs 2.3kg with new packing and makes about the same noise level as the standard howitzer.
I dont think theres much scope left for tuning the 630 other than mapping and exhaust.
Hasnt the factory already brought the 610 motor to its mechanical limit with the 630?

Not really, the 630 is rather tame for it's displacement.
It could use a higher compression piston and some hotter cams and it would hold up fine as long as it's treated right, there has just been no significant aftermarket for it in that respect.

The bore is only 2mm bigger on the 630. Compression difference, 610-11.0:1, 630-12.4:1.
How much bigger would be possible? and how much higher compression?
Would 510 cams not fit in a 630?
 
All parts on order through Halls. Great customer service with these guys. I talked to Bob, he was very professional, keyed up all the part #'s & informed me right away that 5 parts were on back order. Was upfront that they'd possibly be in approximately one month maybe more. Everything has been boxed up and bike is already off the lift, I need it because I'm 90% to getting my project bike running. Looks like I'll be riding the WR & Ducati this summer, maybe I'll get lucky & the husky will be OTR early fall. I really wish there was as an Athena kit for it, it would be awesome since I already have it apart.
 
Eh, that was much easier than I thought. Lump is all buttoned up. Just need to put the airbox/bodywork back on, fill the fluids, give her a good wash & it'll be ready to go.
 
Sold it.......guy is picking it up on Monday. I sold my WR 400 too.....got a KTM SuperDuke R for the time being.......are the 701's coming stateside? And who's got em?

I have to say this though........steer far from Roost Powersports in Thomaston, CT. Everything that could have been set/adjusted/shimmed/etc was wrong on that bike. The manual is very specific about the shimming of the cogs in the gearset, it was way off, both the intake and the exhaust cams were off by a tooth, valves were fine but I'd checked them each oil change, I can't recall all the minor mistakes but as I was disassembling the motor I referenced all the pics in the manual and more often than not things weren't right.

Bike runs like a top now (it pulls noticeably harder through the rev range, starts on the first revolution of the motor and is void of any hiccups, flat spots or stumbling) but my ass is already chapped by this experience. Too bad, it's such a great machine, I really enjoyed riding it. I just can't get past the lack of parts availability or dealer support......it's cost me less than $1k in service/parts in 5 years, but then again it's only got 36xx miles on it......

So I think I found the culprit. The selector mechanism seems to be missing the cog that it mates with:

The first pic has it sitting where it's supposed to be, the second is it pushed out. Judging by the scratches made by the shift lever on the left side case cover, it's obvious that the cog was being shoved away from the selector cog that's attached to the drum.......I'll need to inspect more to figure out why it's happening.

I read that you sold the bike, but for those who might have the same problem it is the bushing with part number:8A0031503 that is probably the cause of the teeth misalignement on the shifter problem..
