    Is your front rotor oversize? What is the dia? I'd like to use a 320mm - anyone ever use one that large?

    I run a 320mm on my CRF500L (mostly to appease the insurance engineer) - is does awesome stopies :)

    I believe it's a 320mm. I figured with the extra weight, I could use some extra stopping power.

    The engine is all back together with the ported head and high compression pistons. Decided on the K&N pod filter directly on the throttle bodies. I'm going to custom make an airbox between the frame rails and then use the stock airbox for the electronics and battery. I'm going to try to get it to the exhaust guy next week. Decided on a Rally style, low exhaust and use a SuperTrapp IDS2 quiet series muffler.

    Pickup the motor and frame yesterday. I was lucky enough to have Arnie Heller, who has built world record Funny Bikes, do the engine build. He installed high compression pistons, ported the head and did some other odds and ends. The engine ended up dead center in the frame which made for nice fitting throttle bodies and air filter.

    How close are you to a test drive? This sucker should be nice and light.

    It will probably be with the exhaust builder for a couple weeks and then with the tuner for a couple weeks so about a month.

    You'll probably think I'm crazy but I'm thinking to switching motors. When I first started this project the KTM 390 was just coming out and I wrote it off because it was a single. However, it's proving reliable and smooth running. I think the 390 motor weighs about 20lbs less than the Ninja 300 and probably makes similar horsepower to the built Ninja 300 motor. The KTM 390 would give up some rpm and has a closer ratio transmission. But 20lbs less. I'm just researching at this point.

    Whoo - not so fast there

    I thought you were after the elusive perfect Adv bike - everyone knows those have at least two cylinders for the sorry time you have to be on tarmac

    Don't do it. This one is practically done. Build a different one and sale this one to me

    I forgot where I read it but I saw a new term "Travel Enduro" which is exactly what I want.

    I think KTM is proving otherwise with their newer 690 and 390 engines. I like that the Ninja 300 pulls much higher rpm and has a wider ratio trans. Besides how heavy the Ninja motor is, the oil pan sticks way down and loses a bunch of ground clearance. Main reason to stick with the Ninja motor is timing. Switching to the KTM would add a couple months to the project.

    IMHO an ADV or Travel Enduro bike needs a Wide ratio transmission.

    Follow your heart, it is your project after all.
    I would only suggest that since you have gone this far, finish the 300 install and see if it accomplishes your goals. If after that you still want to try the 390 I am quite sure you'll have quite a few inmates lining up to buy the 300.

    If you buy a KTM 390 and get it installed, then you'll want the new Ninja 400 motor...(I know I wouldn't mind one, but it'll likely take a couple years before they start showing up as affordable/wrecked bikes)

    You've got to draw the line somewhere.
    Eventually, there may be a 50 pound engine that produces 100 hp and gets 100mpg.

    While you could wait for that, wouldn't rather be riding your bike instead?
    You're almost done. It should be a great bike just the way it is.

    Weighed the bike today. 278 lbs without fuel. That's with hand guards, rear luggage rack and skip plate (probably +10 lbs all together). Plus 2 gallons of gas (12 lbs) and it's 290 lbs. If I put a 3.4 gallon tank on it than it would still be under 300 lbs with a full tank.

    Finally got a weight on the 390 motor and it's only 14lbs lighter. I don't think 14lbs low in the chassis will be all that noticeable however I think the extra power and extra rpm capability is. Decided to keep the 300ex motor. Haven't had much time to work on it but figured out the foot pegs, rear brake pedal and shifter. Had to lower foot pegs and controls an inch to clear the clutch cover.

    Good choice to ignore the 390 KTM motor. It has not proven to be reliable. Valve keeper problems, head gasket problems, pistons cracking... not a first world engine. The 350 KTM motor is 10x a better motor.

    Thats good if you want to make your own adventure bike. I think you should think about Yamaha TT 230. It is one of the best adventure bike with some off-road characteristics. I has an outstanding suspension and braking system. Moreover you can also modify it with the help of Yamaha TT 230 Service Manual.
