greencannon:
sorry about the pic quality, it's all i had
That little spot on the left let tiny grains of dirt thru which caused havoc with my motor until I noticed it and fixed it and replated with apticote. now so far it has been  bullet proof
i only bring up this incident because it also happened to a riding buddy of mine with a K5.  It was also in the same spot...
 

oic0:
Thats right where mine sucked mud. I bought a new boot and plastic thing, it still does it. I spent a solid hour fiddling with it just to get it somewhat tight at that spot. Going to silicone it.

kwakman:
@motorrad, too true mate.

@johnny 500, im in nottinghamshire, so we aren't far away from each other.I have heard that the hotrods rod for the kx5 isnt too clever, so was thinking of going with vesrah.I too have chosen pjme for the crank build as I want it as true as possible.What yr is yours? Mines an 86.Maybe when its done we could hook up for a ride?

@cbmoor,Im gonna register it for the road primarily, so will be in sm trim.

@greencannon, i always make sure the filter is doing the best job possible as dirt and strokers dont mix....I have never heard of Poeton, but will look it up, thanks.

I have high hopes of the ceramic bearings and iso superfinshing, and will share any useful info i come across.Gonna buy a new phone so i can post pics at each stage too. Thanks for your input guys.K.

heres my build so far kwakman. its an 89-04 motor in a 99-02 kx250 chassis mx. i already have  my wieseco piston got it for ?110 of ebay in uk but it was a 1 off, i have a set  of 02 crank cases coming from the u.s. i am stuck on the conrod though as i have heard some horror storys of k5s snapping them. i think i will start a new thread and ask the guys from the u.s what they think. they have more knowledge and experience with these motors i think. your bike is an sm?

kwakman:
its not an sm yet but it will be.Pics of it in gallery pre stripdown under kwakman.stay away from hotrods on a k5 application.you can get forged vesrah rods on ebay from us for around ?50 -?80 plus postage.Much cheaper than in UK.I have done mucho research on where to find stuff as cheap as poss, so give me a shout when you want to pick through this brain of mine.
