  • 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 The previous version was outdated and no longer supported.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 PV spring install

Hi all, long time reader first time posting. Mainly use an Aus dirtbike forum, but this one has a wealth of info. currently own a 11 150xc

Seeking some advice regards the changing of PV springs from the spring kit.
I've done it twice and stuffed up both times.
First time the spring governor was very hard to get out and popped out with a loud clunk, but went back in okay. Second time the governor came out easier but still with a loud clunk snap, but was very hard to get back in.

According to my mechanic I had burned the PV gear and was also a tooth out.

Is there any way of knowing if your a tooth out or correctly aligned? Can you simply look at the PV through the exhaust port?

Have currently got the White / silver spring but still have a dead spot that is more pronounced then the stock spring so want to try the stock/ silver spring.

Finally why do the instructions say " Be warned that is no fun adding the smaller springs to the stock spring"? I see a few 150 owners have gone to this combo

Info greatly appreciated, hoping to change it out and test tomorrow.
 
3rd time unlucky again :banghead:. Finally got the governor to pop out but in doing so the linkage shaft jumped a tooth and spun around so it went much further then qtr turn.
Have no idea were the linkage shaft should be positioned. (The little gear on it thats inside the cases that has one tooth missing, how does one know what position the missing tooth should be in)?
I can get the governor to slide back in but there is very little load on the PV or the PV actuator arm. you push the arm up and the PV's just stay up :confused:.
Knew I should of just left it alone and gone riding tomorrow.
 
There are only two positions where the shaft will be in the correct place to allow full range of motion of the power valve and still have the correct amount of pre-load tension with the linkage adjusted close to the middle. Do you have the install instructions with pic's? If you don't and will pm me your e-mail address I will send them to you with pointers.
 
Thanks for that, Yes I've got the instructions. Didn't seem to matter what position I tried to have the shaft in it never had the correct preload tension. The PV would only go under tension when the were half way open.
I've now dropped the bike off to someone to do it for me.
Not sure where I was going wrong, for something that looks so very simple:banghead: . Would be good to know how its done myself as possibly I won't like the stock / silver spring combo.

As i am not getting full range of motion of power valves I am looking into this area
The shaft on mine seems to have a side with three teeth worn down which was the side facing down when I opened mine up
Is this wear? Does shaft spin around?
How does it work?

If I rotate the shaft to other side the teeth are good
Cheers
 
I have full range of arm as shown on pic 1 with the limited range marked on left
Bolt in centre of slot
This limitation now occurs only when i replace cover to governor

Like luke in this thread i am Not sure what the correct technique is to insert governor gear back on to shaft

I must have had this issue for a long time. Hence poor performance

Anyone done a PVC spring change ? Any ideas Why the governor is limiting the Power valve motion ? Governor installation technique?
Edit: found that the movement of the arm is actually greater than what it is when you move it manually
That is : when u push on governor it and depress spring the arm goes all the way up
Strange thing is the mechanism doesn't always activate but seems to always work when running
Tested with bolt at top of slot for low end - good closing of pvs. and seems to be getting good range of opening
Strong power bottom to top
Will keep testing for preferred bolt position
 
probably not much help here but when I overhauled the engine i had also some difficulties with getting this one right

took me about 3 attempts to get it right

still have to come it my way as my power valve actuation have to be replaced completely now, all components have simply to much leeway

did ask the price at halls already and pleasantly supriced by the price of it

the only issue now is to get it here

working on it

should be in the same package as a lectron i guess:rolleyes:
