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 The previous version was outdated and no longer supported.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

I was fairly deep into installing a Blaster 200 aircooled engine onto Y2.1 K steel frame YZ125 chassis to build a simple air cooled 2 stroke trail bike in a good chassis config........after seeing the X trainer type bikes, and especially the AJP bikes I threw in the towel on it.
I still think its a good idea, but not worth my time (effort is fine, time is not).

So the basket case YZ125 is going to be restored as a side/loaner/track/fun bike. I bought a new chassis (MY2000) because I had already modified the 01 chassis and have all the 2001 parts. I will snap some shots of it as it comes together. YZ125s have been my faves (and seems like everyone elses too-MXA, DirtBike etc). Plus side I still like CrMo chassis machines so the Y2K machine fits the bill.
source for "new" chassis was local San Diego zone dismantler (Escondido) and price was very fair/low
Damaged Goods is the company, they do a strong ebay biz.

My sponsor shop has me covered for all the hardware stuff (UFO Plast, Works connection, etc.
NCMoto.net

I slipped from my shop and bought a graphics kit on ebay(the bane of my friend's small biz)--the Flu Designs (gotta be China) for only 50 bucks for a full graphics kit and I installed most of it onto new UFO plast (all white), the cheapest of the major brands was mid 100s.......

Want an X trainer type bike on a budget? Grab a CR150 and I'll tell you what to do to the motor to give it a beautiful linear power band. I rode the X trainer (and all the Beta 2 strokes) back to back with my CR150 and was surprised at how similar (and better to me) it felt to the X trainer... and I really wanted an X trainer
 
Swingarm painted (over the old OEM paint) and Subrame painted to metal color ( this is not going to be some crazy show bike, but all my stuff needs to at least look cool.....)
The reason the Previous Owner took it apart was for a kick starter pawl assembly fail with subsequent metal parts scattering into the gearbox. After a good inspection of the engine parts, they are amazing in good shape with little wear, with some minor exceptions. I will skimp for the reassembly and have a new kick starter shaft and I found one case bearing that needs replacement.
All the other bearings feel good and look good, besides its a 125....I'll put it back together and run it, if it blows I'll rebuild or source another engine! These early 2000s bikes are super cheap right now. I noticed something odd MXA and others all have the main very near to the OEM main size @ 460, PC lists it as a 410, this bike has a 410 and shows evidence of lean/high heat burn. The piston (which needs replacement) has some exhaust edge erosion and a lot of burned carbon on the underside of the crown. I will get the thing back to the MXA (OEM) happy jetting spec. The PC spec is also based on 32:1 with C12 VP leaded racing fuel so that may explain the spec to some degree.
Oh and that's my little bitch (hahaha) Paloma AKA P-Lo guarding the parts.

Anyone know about/use or used early 2000s Moto Tassinari V Force reed blocks? There is one on E Bay and I'm tempted to snag it and throw on some new replacement reeds.

side note the red bike in the background is a regret bike.....when I got it 20 od years ago it was a fully configured XL80S with all the street gear on it or boxed. At the time my daughters needed a learner bike....so I stripped it and converted it into an XR80R. My regret I should have left the dang thing in OEM form, it would be fun to have a street legal Grom from the old school!! The non regret part is that both my daughters learned to ride on it and refuse to let me get rid of it!! Its got an XR cam with on open airbox, XR carb and a Poweroll pipe on it, with Maier plastics.
 
I've got a 77 Xr 75 my dad bought brand new. Awesome little bikes. My uncle did a bunch of head work to it and it's got a bassani exhaust and a cam. I plan on resto modding it in the future. It moves pretty good with an adult on it. Practically my whole family learned to ride on that bike and then some. Probably one of the best things Honda has built. The yz is looking good!
 
I know a guy that did that very same thing. Says it's a blast to ride, no pun intended. Had the suspension set up kinda springy like a trials bike and made a KTM200 pipe fit.
 
Not to sure on the 200 pipe on a 125 much less a 150 but I'd ride the s**t outta that yz. I'd pound it. Nice build robertaccio. I'm happy to see one of these bikes get the attention they deserve.
 
the shock and forks are in for service special treatment at Suspension 101 Alpine/San Diego. George has been doing wonders for Noah Kepple's machines among others including some legend riders. I told him its a fun bike for a maybe intermediate MXer and only for natural terrain mx like cahuilla type stuff------no silly jumping hits...R-accio does not jump!!!
 
chassis build and style coming together well. suspension is in shop as stated above. Motor inspection revealed a few worn parts (on order) and I need a seal kit, most bearing appear fine. Funny thing- I was going to replace the power valves....but at @ 200 bucks per side I will do some work on them.

piston kit on order now along with an seal kit to go along with the gasket kit. The chassis is pretty much done when the suspension comes back from Suspension 101
 
that bLU cRU hat was gifted to me from my sponsor shop parts manager, I guess he got it from one of the supplier reps.
 
still piecing together stuff, ended up buying a new V Force 3 reed assembly.
cylinder clean up and build up /re-assembly of PV parts is next.
received a bunch of oem parts that I had ordered, seals, bearings and hard parts
 
was AWP awaiting parts. found 6th gears both output shaft and pinion shaft had cracks, glad I did a really close inspection. got one from oem, one was discontinued but I found it on ebay. gearset is dialed. mock up to join cases found I needed o ring and sleeve for the coolant passage waiting for those parts to join cases. Its moving OK not in a rush, just ordered number plate graphics from Decal MX. will start to burnish all my chassis ground points to prepare to mount the electric components. Its very close. mainly waiting to reassemble the engine. Suspension is mounted and has been fully dialed by Suspension 101 (local and good), seems like I have most everything else. cant install my extra flexxbars, oem triple has cast in handlebar mounts so the cross bar renthal will be back on. I have flag handguards and a hyde skid plate just to keep it somewhat ready to do trail rides.
 
from notes above--- cylinder and PV assy went together really well with new shaft seal. and added heat shrink sleeve on the power valve control rods, because they were worn where the springs act on them, so the heat shrink keeps things snug. I filed the piston ends of the PVs because they were touching the piston before. there were evidence marks on the piston and on the ends of the PVs. I have the new piston, its the exact same one as the one that came out, wiseco forged. kept same size.
