    Here is one of the latest projects! Some of you may know I have been riding a 300cc stroked WR240 for a year or two now, but I am building a 3rd one to test our new Aluminium cylinder liners. I will have 5 special barrels ready to accept some of these next week. They will then go off for porting and Nakasil plating. I am working on producing a batch of special crank flywheels that might end up a stock item too...
    The front forks are some of our modified units with the last of the Evo internals - modified. Way better than any gold valve, as all the damping is done at the very bottom of the fork. This means you always get damping - unlike the ones with the valve on the top of the damper, where often there is on oil to go through the valve!!!
    Robin Packham at Falcon Shocks is building me some Adjustable shocks that will become a product.
    Electrex will be supplying the sparks which we will again be stocking soon.....AndyElliott.

    The bike in the background is the WR400l/c 1984 that is going to feature in 4 issues of the Classic Dirt Bike magazine...

    By the way, my offer still stands that anyone (one rider) willing to travel to the UK from far afield in September for the 'Hot Trod', which is our best big Vintage Enduro (and is in the Noth of England) - will have the loan of one of these bikes for the entire weekend!!!
    Fly into Edinborough and I will pick you up and look after you for the weekend.
    All I ask, is that you enjoy yourself - riding a hare scramble on the Saturday and the Enduro on the Sunday.
    See www.vindurouk.com for event details...

    Hi Andy
    Can you remind us the bore and stroke differences with 240/250 ?
    Thanks

    Andy,

    Down the road I will need a 500 ignition as well as couple more.

    Probably one for a 82 125 and 79 390?

    10 mm more stroke than the 250 Michel and a 70mm bore. The key is the correct crank mass and balance and a compression change though....

    Oh yes a new carb. and a change of jetting too.

    Oh yes, I forgot to say I just pressed one of these liners into a 84 L/C Cylinder for a liquid cooled 300 twinshock that will be under test!

    OK ! And why didn't you choose a standard stroke with a bigger piston ?

    If this offer still stands, I'm totally willing and able to come. Can reciprocate, like maybe some high country riding in the Rockies, or Moab?

    I'm back!

    Thanks for all the interest in coming to the UK! I have accepted an offer, so, sorry to the others!

    Anyway, here is a pic of the Alloy liners for the 300's...

    The Forks:

    Take a set of Evo sliders and mill off the disc lugs. Alloy weld up what is left of the holes from the disc lugs and machine back to make them disappear. Powder coat white and they look like the 83 / 84 bottoms. Take a set of damper rods from an 88 Enduro bike and fit them together with new seals and bushes. Fit some hva-factory Titanium bottom fork washers (they have an 'O' ring groove to seal the bottom and don't crack when you tighten the damper rod) Make sure the forks are compressed when you do up the damper rod - You will need a special socket to stop the damper rotating... Fill with 5w oil to 220mm air gap compressed with the spring out. Fit some springs and you are there. I will do a damper upgrade in the near future. One of the advantages of the evo fork is that they use a topping out spring - so no more 'clunk' when the top out washers are not under oil or not flat! The main advantage is that the damping is conducted at the bottom of the fork...
    There are upgrade parts for the damping internals that I may make if the demand is there.

    The Cylinder:

    There are 3 variants of the aircooled 250 primary kick cylinder. Most are missing 2 x extra induction ports at the gasket face on the inlet side and 2 x extra exhaust sub ports. You can add both of these with some careful machining work if you like. The 300 Liner is also 5mm taller. This is for the extra stroke.
