Get hold of Darryl August, his goes well. Capt88 might be able to help as well

Been around for quite a number of years, only have experience of their 28mm d-slide carb, have a couple of the power jet oval bored 30mm carbs which I suspect may be the copies
Early versions weren't known for having great quality chrome on the slides but I haven't had any problems
Main improvement with trials bikes over keihins that have been noted worldwide is less fuel out of the overflows when hopping. I picked up 1 of the clear floatbowls which is quite helpful & really cheap

I've fitted a couple of smaller PWK's and found same deal with slow running and pilot passages. Also found that the seal of the jet block and the passage alignment might need a blueprint. These were OKO branded units.
Those will be the Chinese rip off Okos, saw a thread on how to pick them. Real Okos have Taiwanese flag on box is first clue, next is jets actually have markings
Have been running a real Oko for years on my Sherco & it's as good if not better than a Keihin PWK

So far the bushes listed over the counter are either 32mm or 35mm bore so it looks like it may end up being bronze bushes made to fit

Tech Talk / Sloppy 34mm forks

I need to fit bushes to the top of my TY250 forks as both legs blow seals & if I grip each leg with the wheel out there is definite play in them
Does anyone know of a 34mm fork that has bushes in the top of the sliders or am I going to need to custom make a pair with a fairly thin wall thickness?

Are you saying the timing marks were out?

How light do you mean?
Full circle racing's site seem to show a couple of different shades of gold
My YZ465 had old Sun rims, not sure how that compared to what they do now

Penton imports has given up selling PVL so you'll need to look elsewhere

Not shown anywhere as a separate part, everything else apart from the main body look to have been able to be bought separately
Quite possible that it's common to a heap of taps but you won't know without comparing. John Tate (Davey Crockett) may be able to confirm, he did a run of replacement threaded sections for tanks that fitted multiple models

I for one hope these old bike forums don't die out , to be replaced by the dreaded Facebook.
But if that is what people prefer it will happen over time.
To be fair Facebook+groups don't seem too bad,
its Facebook+ individual people is where it goes wrong, and gets a bad name
The Photobucket situation doesn't help forums, but what will happen when Facebook end up owning most of the internet  ?
I bet they will start charging $$$ just like Photobucket
Who do you think owns Photobucket now? The huge number of ads started around the time Zuckerberg bought it

Competition / Re: VMX ........... PRE 82 or EVO or pre 80 or pre 85

What Brad is getting at is in Europe people are taking linkage bikes & welding shock mounts to the frame & swingarm, using late 90s conventional forks with brackets to anchor brake plates.
I've even seen hubs machined to run a DLS brake plate on each side of the front wheel
Would you really like seeing a class of these bikes running at a VMX event? Sure Evo isn't perfect but at least the bikes actually existed back in the early 80s

Strange place for them to go. Do the bikes run head stays in about that point?
Try rubbing both head & barrel on wet & dry sitting on a piece of plate glass to see if 1 of the 2 has a low spot

Prototype monoshock dirt bike was a CZ, both CZ & Suzuki turned it down before Yamaha bought the idea
Shock used in the prototype was out of a Citreon from memory

I'm interested to know what piston your using (single ring) if you don't mind sharing..?
Markings on top & lack of teflon coated skirt would suggest Wiseco

Should be a easy job, get the old 1 out & measure what size the shaft is to make the hole the right side.
Anyone who can use a lathe half decent can whip a new 1 up quite quickly
