    Well the water pump has sorted the cooling issue. I've removed the thermostat and made a big washer so that it doesn't leak. I had to turn the rd around to get the stock outlets where I needed. By the time the clocks read 50 deg the rad is hot. Winning! The pump is of the Davies Craig flavour and I highly recommend it to anyone looking to boost cooling potential at low rpm. I'll make a proper bracket for it shortly. here are some photos.

    Brilliant effort. Good on you, lad.

    Just saw this bike the other day. Perhaps it'll give you some inspiration. :wink:

    That looks awesome. Nicely finished and more complete than mine will ever be. I like the breather solution into the subframe. Might try that on mine. I know it all seems to have gone quiet but Im slowly sorting things out. Been really busy with work of late. Made a header tank yesterday, will get some brackets on it and hopefully route the cooling hoses by the end of the month. I'll try abs put some photos up when I make significant progress with it.

    I've made a header tank and a bracket to hold it in up the front that also replaces the original radiator mount, (No penis jokes please :rofl) will get some grommets and weld some bosses on the header tank to isolate it a bit, need to make another bracket to go on top too. I've got a filler neck and some stainless hose joiners to weld on to finish it.

    That is looking brilliant mate!

    Small world, I did Automotive Engineering at Loughborough Uni and was a member of both LSUMC and LSUMCC while I was there. I'll be following this as this looks mad as a box of frogs. :lol3

    Pretty sure I saw you asked to join the LSUMC the other day? Think Matt added you, he's running the facebook page on his own whilst I'm on placement. Hopefully I'll be more involved next year. :D

    I've also given up with the fuel cell idea and cut up an Old RGV tank I was given by my good friend Ian at BikeMotorWorks in Grendon.

    It's taken a while but I've been busy. Finished welding up the tank and had it painted at work. Unfortunately the fuel tap fouled the subframe so I had to change that too. I've also incorporated the subframe as an oil catch tank as seen in the posted link. Then I adapted the side panel around the new tank and re fitted the seat lock. Also I welded on a stronger exhaust mount and reinforced the engine mounts. I've now sorted the cooling system routing s well but have no photos yet. Loom to go in again next week.

    Long story short, the bike is now technically road legal! Passed its MOT last week but I can't use it until the DVLA pull their finger out and tax it! Utterly useless they are. It's changed somewhat from how I intended. A person who shall remain anonymous dropped part of a paddock stand on the tank so I had to repaint it and decided to apply some decals at the same time. It was a bit bland as was. Work kindly laquered all the panels for me and it looks ace!

    I've clocked only 14 miles from new so far. To the MOT station and to the post office (where I was denied tax) then home again. It pulls strongly to around 5k then tails off somewhat to a peak at 7k revs. The fueling needs work at the top end but I'll play with some options when I've done a few more miles. On the plus side it will wheelie at any rpm in first and if you snap it in second. It will clutch up in every gear! I weighed the bike without the fairing and 2 gallons of fuel at 70kg R 71kg F so I reckon it's under 150kg wet as it stands now and it will only get lighter. With some time and effort I think I could cut upto 20kg off the bike with aluminium parts and a track fairing.

    That is one very nice KTM!:clap

    I wonder if your fuelling above 5k is due to the little air filter?? Any way to get something larger on there? Or just remove it for a test run to see how it operates?

    I have a JD jet kit on my FCR and the jetting seems spot on for me.

    Cheers
