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 The previous version was outdated and no longer supported.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

125-200cc Chain roller sizes

32, 36 or 42mm? What size is stock? Better to go for biggest to allow for wear? I chucked one out as the bearing literally fell apart when I went to regrease. In hindsight should have just bought a new bearing(hadn't worn much) but didn't realise could replace em
 
Which bike mate. If it's the 165 I can measure the corresponding roller on mine.
I'd recommend staying with the original size......something to do with chain tension at the extremes of suspension travel.
 
Top n bottom the same n same on 300 n 165. The bearings shit emselves so best to regrease em every 6 months or so takes 5 min. I have to keep swapping between bikes depending on which one I wanna ride n it's gettin annoying

If you have the time and patience; you might look at the bearings for roller blades at the sports store. Sometimes you can buy the right bearing pack to repair 1 set of rollerblades OR use the bearings in your chain roller and have 8 or 10 spare sets.
 
The bearings for the chain rollers on my 250 are 6801 which should be the same as all the stock rollers.
 
So oem dimensions are 32mm diameter n 28mm width with an m8 bolt correct? Sorry forgot to measure whilst at home n now back at work. I'm looking at some Chinese ones on fleabay(yes I'm cheap) which are 35mm diameter n 26mm width. Surely coupla mm make bugger all diff?!

There's also some flash red ones that are recessed in the middle so prob only 20mm thick where chain will contact it. Likely to affect anything?

Wouldn't mind the red as I wanna get the TM design works red slider n guide so red to match but the red TM rollers are like $60aus so hard to justify for chain rollers when I'm not sure they do much(not as much as the slider m guide anyway!). Plus I need four for 2 bikes so really exy! Thoughts people?
 
Go for it mate. Get the red ones. So long as they keep the chain from eating the intake boot and anything else nearby you should be fine. Just make sure the recess in them is wide enough that it doesn't bind on the chain and that it doesn't try to miss align the chain with the front sprocket.
 
I just put some new red ones on the 144, 34x28mm, cheap and get in a minor bind when tightened. Still work fine though. TM Designs just OK, overpriced IMO. I'll get BRP next time.
:cheers:
 
We happen to use Delrin at work, so I use leftover pieces to make my own. For the bottom ones I use a bearing, but the top ones, I just drill an 8 mm hole, as the roller only makes incidental contact, and IMO, a bearing is overkill, complicated, expensive, and heavier.

What brand/sort(recessed type?)/price Steve? Ebay specials?
 
Yes the recess thing concerns me a little when susp fully compressed. Worried if not aligned may cause chain torque/twist like you say Oldscool. Cheap enough to try I guess. We have poly pipe(black) at work that can make some out of plus white nylon could do same but really want red! Can't find any non recessed red type on fleabay?!
 
Bam found some for $25us delivered! 4 of em too! Normal type not recessed & run a bearing(coming from china guarànteed high quality haha). They're only 30mm diameter but have the 'powerlip'(TM design works rip off) which is 4mm more OD. 30mm long so slightly longer. Found em under 'red chain roller' on ebay. Mx pitbike the store name. Goes to show simplest description often the best with fleabay!
 
One more question there's a red slider on ebay that fits late 90s-02 model 125/250/360s. I'm fairly sure it's the same swingarm on the newer 300s hence same slider yeah? TM design works don't do one it seems n rest are black. Cheers yall
