Hi Brock,Oh man these things really do have issues with clogging up with coke don't they?
It's one of those be extra careful to clean the hole out jobs and not easy at that.
For sure these valves aren't the same as the KDX200 - that whole arrangement with the pin and groove arrangement which I guess is for lifting the central exhaust flap valve are not present on the KDX200 - just checked on cmsnl.com (consolidated motor spares, netherlands) and the part numbers are different.
What a bugger - and I bet these are only available in ally too.
Good move on buying up a bit of stock - I'll see if I can buy myself a set for future use, although at £45 each plus VAT that's going to be an expensive pile. Which model year KDX250 are these off? They look like E model valves. It seems to me that pretty much every model of every type of Kwaka had slightly different powervalves.
I will be straight up with you I don't think I'll be getting round to these any time too soon - I first have to let the investment of a production run of KMX200 & KDX200E valves at least pay off before I can pump more money in (we are such a small company remember, with fingers in many pies). It may well be 3-6 months before I get them on the go, depending on demand.
All the best,
Brock
Hey Paul,
Part numbers are not the same.
Pretty much all KIPS valve parts have the same prefix (12005) but the part number includes four numbers after that (see more info on cmsnl) eg 12005-1141 , 12005-1142, 120051121 etc etc.
It would be possible to fix the peg in these valves if that is what breaks - if the shaft shears or the gear teeth damage then a complete valve would be required. Fixing the peg would just not be worth the money I think though - might as well buy a new valve.
If it's only the bottom peg you could drill and tap the body - wind a bolt in there and then turn off the threads down to size? Tough bit is getting the peg concentric and straight.
I've put you on a wish list for these valves - I generally wait until the wish list is sufficiently populated before considering the project.
All the best,
Brock
