    Spacers under carburettors

    I was going to leave to cams till after the fine tune but then it will change things so I know you are correct in saying I should change the cams first.

    Spacers under carburettors

    Mixture once on full throttle was constant 12.5:1 the throttle plate was only opening to about 11 o'clock(sorted) and there was a unintentional venturi shape in the plenum(sorted but unproven). It was all a bit rough first time out. Not being a normal carb but rather a mechanical Map sensor...

    Spacers under carburettors

    A bit out of date now but this is from my only dyno session to date. The bottom end mixtures were rubbish but I think they are much better now. this compared the toque of my 02 650 with fish carb to a 05 FI model with k&n filter and slip on. My goal is to match the top end power of the FI model...

    Spacers under carburettors

    I have converted my bike to a single 41mm Fish carburettor in place of 2x 39mm Mikuni carbs. and first dyno run was pretty good except for rick idle and part throttle, WOT wasn't bad for first go. Great torque better than stock and only 2hp down at peak and no big drop off even at the rev...

    Ton up SR250: 100mph, 100kg, 30hp

    It's a funny thing I never seem to make it to the first time I book for a dyno, always something happens. I had a suspension business and I was asked to cast an eye over a salt lake rocket car. The first thing that came to mind was, this thing is very heavy, not what I expected. I was told...

    Ton up SR250: 100mph, 100kg, 30hp

    https://www.rideapart.com/news/254553/how-to-set-a-land-speed-record-on-a-3200-motorcycle/ I think this is worth a look it may just make you think of something. They did offer for sale a 300cc LSR version the more you paid the closer to the true Land Speed Record spec you got. I thought at the...

    Spent time today doing a final trim of the tank shape, so apart from changing the fuel filler area, that is the look.. That is the final shape no real changes now just need to get stuck in and finish it. Plan is original hinge mount on the rear, standard petcock, Honda fuel sender compatible...

    looking back at pictures testing the fairing fit makes me feel better, concentrating on the tank I start to lose prospective

    Getting there slowly I have welded in the piece above and I am getting better, although far from picture book. It has caused shrinkage across the tank between the airbox and fuel tank but not twisted. I have made a flat bottom for the fuel part which is a really good slip in size but without the...

    Been a while but long story short, My welding mask wasn't good enough for me to tig weld. My first attempt at putting the above panel in the tank "tanked" looked like bird droppings and blew a hole but it was tacked in. I wasn't brave enough to try again till I got a better mask. I got a mask...

    Back to the fuel tank, just got some gas and have started bending up the main divided on the under side between the fuel and air box. It took some head scratching but I decided by putting a flange around it I bend the flange in and out for a perfect fit to made welding easier which I need with...

    Vapor blaster

    Sounds good let us know how it goes, I made a sand blast cabinet and the thing I hadn't allowed for was the huge static build up and it was unusable till I ran a earth strap from the nozzle.

    Had no time or money to buy shield gas lately so today just did some pounding on the tank blending to bar dents into the extended shape.

    Thanks for that. So sounds pretty right to me then. It does feel good to me on the bike now and the foot pegs feel better than when the tank was shorter so that's a win. I have just worked out an articulated front fairing bracket that will give approx. 25mm of up and down movement and tilt...

    After rotating the bars I think it's ended up ok I haven't measured with a protractor but the droop would be about 7 degrees and the bar ends are about 130mm above the seat. What's your ergonomic thoughts ?

    I adjusted the other bar to be the same and did some more welding on the tank. Unfortunately the wind picked up and the gas ran out so I didn't get as much done as planned, but for only the 3rd time tig welding I'm happy and learning as I go.
