Freaky - I will see if Gary can send you the details as his mod was quite easy to do - didn't involve machining up a sparkly arkly new cover though - so dont expect one of those?

[Rossvickicampbell]

and we never did find out whether the clutch actuator cover that started this thread was ever going to become available to buy?  DJR - is he interested in turning some up?

cheers

I found a guy with one of them crazy axis cutting things, but im now more interested in finding out if he can remake the worm drives for the Actutor, i have a box about 20 of them and there all forked, cracked, split and so on, the plastic helix worms diditn last time........  there must be a substitute worm or someone who can make them up.  or failing that redesign the mech at a cheap enough price to be able to use them.  Anyone heard any alternative or movements in this area ?   yer and im alos out of Dt cases so im on my last cover and actuator.......... so this is a poinient project.

( if you can get DJ to get that "G" code from that bloke we can get our own made Ross from this chap and then work on a mech system to suit us)   Davey ? ideas and are you in too.....

Hey amigos! Gonna try restarting this old thread; About to start a yz360a project and need the clutch actuating cover.  Did anyone ever find the person that made this aluminum machined cover above or the G code for it.  I want to buy 2 of these covers.  Also, saw the info on the xs650 clutch mechanism and found a really nice kit from this guy in germany on ebay for around $77,  go to ebay and type in xs650 clutch and you will find this very great deal.  Regards

He's racing the MrVMX series over here in NZ this year, TMBill or Bazza may know how to contact him to see if he would be interested

If anyone can tell us where to buy these gizmo's you can count me in for two or even three. As much as I love the old DT1 based engine, the clutch actuator is their Achilles heel. Because of the damage a derailed chain can do to the cover and actuator, it's imperative to use a chain guide and/or tensioner. I use old school spring loaded Pro-Fab tensioners or these cheap and cheerful little chain guides from our Chinese friends for less than $20 landed http://www.ebay.com.au/itm/CHAIN-GUARD-GUIDE-China-XR-CRF50-KLX110-style-bike-see-size-/160708571998?pt=Motorcycles_Parts_Accessories&hash=item256afa335e#ht_4199wt_698


While you're checking out the chain guide, I can recommend these billet alloy throttles. They're all CNC machined alloy and are as strong as a slant six Valiant. I've got them on a couple of my bikes and swear by them.....all for less than $30!http://www.ebay.com.au/itm/Gray-Color-CNC-THROTTLE-CLAMP-7-8-CRF50-PIT-DIRT-BIKE-/160711961274?pt=Motorcycles_Parts_Accessories&hash=item256b2deaba#ht_3793wt_698

While some of their stuff is still shoddy shit, the Chinese are really picking up their act and many parts such as these shown are as good and often better than the mainstream stuff. In fact, you'd probably find that the parts you pay big dollars for from the USA or the big Aussie retailers are made in China right beside this cheap stuff.

HENCE THE dELEMA- BETTER  CHINEESE SHIT (LIKE METISSE FRAMES) OR TRY AND SUPPORT LOCAL MANUFACTURING SO WE AND OUR KIDS HAVE JOBS

[firko]

I agree Mike...as soon as someone makes these parts locally for the right price, I'm first punter in there with cash in hand. I'm hoping I can buy an Aussie or NZ built clutch actuator as shown above, I don't think the Chinese have bothered with them yet . Unfortunately the reality is that we've all been buying Chinese for years....even the Edelbrock heads on you beloved Mustang are made in China .

Let's keep this on topic YZ360B or Yamaha clutch actuators as it's an interesting subject, we've kicked the Chinese around before but if we need to revisit that subject, maybe we should start another thread.

Guys - I dont know how many he has left but I ended up buying three from the guy in the UK who lists them.  I paid $50 delivered to the door whereas the guy in the states trying to sell them wants $200 - and says his are a different type - look the same to me.  Knock on wood I haven't had to change one yet.  Thats the worm actuator itself - not the cover.  I see one of those on US ebay for around $250

[Freakshow]

its th ecover thats the problem Ross the worms are ok but the covers are rooted on the DT1 and RT so they kill the new worms if fitted to old shit.  and the YZA/B cover will no longer get thorugh scrutineering due to the sprocket issue, so these CNC ones would be the go them you can weld in or get 2 threaded 6mm tags on the edge so you can put a cover on the end for racing days.  I have cut up DT1 to look shorter but they still look crap when you look at the YZ covers, and the B being magnesium tend to crack on the wrom etc and i cant get them fixed.  we need to come up with a new alternative.  I know jamie herbert i think it was cast some up in school for his YZ or could have been the other herbert lad that did, either way they dont seem hard to make if you know where to start.

Freaky, I have spoken to a guy about remaking them, he can do it off a sample I have and can change the angle of the spiral to make the clutch pull lighter (fark there heavy)...it will cost money and if there are enough people that want them I will do it...BUT a non refundable deposit will be needed as I have made stuff before and had all the promises...yeah, put me down for 2 and when time comes the only thing you hear is the chrunching of reverse gear....if I do it it will be a cover that can have a sprocket guard mounted to it , look the same as the original and the worm drive assy, like I say, it can be done but wont be cheap so the more that want one the cheaper they will be.

[Rossvickicampbell]

DC - estimate of how much "not cheap" is though?

[Davey Crocket]

Guesstimate would be between $250 to $450....depends on numbers, he explained to me how they where made originally and its not a cheap process...if you look they have a parting line down the middle and are taperred which is what gives them the strenght and lightweight.....remember they where made same as the works YZ before they became OW's. I like the fact that by changing the spiral angle you can have a light "pull"
