In the tests I did years ago having the powerjet discharge end mounted down from the top of the carb bore and later , shortened , gave a smoother and more
gradual flow rate transition much higher up the fuel curve. The Keihin carbs with the discharge nozzle mounted below 1/2 throttle , start to flow almost immediately the slide passes the tube.
Of course later , using a solenoid with PWM drive as Dellorto did , gave electronically the same gradual flow ramp up that didnt suddenly richen the fuel curve in the midrange as soon as the slide was high enough.

Looking at the photo there is a restriction, the adjustment bit, close to the source of fuel. Once the fuel makes it up to the restriction then the flow rate will be restricted. If the restriction was closer to the carb throat like a normal power jet then air will flow through the restriction much more freely and once the fuel makes it that far THEN there will be a restriction to flow. Do like Frits said as well, of course.

Blue line was 100% Methanol, 75 pilot + 180 main. Red line is 50 pilot jet on petrol and 190 main on Methanol. Sounded rich, I guess that is due to the petrol component.



Sucks an amazing amount of petrol compared to the Methanol. Maybe 20% petrol. Dyno's are notoriously thirsty so I expect on the track the ratio of petrol to Methanol will go up, maybe 50% petrol to Methanol. The under the plug cylinder head temperature reached the high 90's C. Exhaust about 360 C. I was expecting a cooler head and hotter exhaust, detonation?. more things to think about.

Having said that, I love the way you use separate float bowls for separate fuels.

Herbert Skinner would be so proud of Rob.

Flanged front rim TX650/750?

The bike is a real mix and match of bits and bobs. 72 XS650 front end or at least bits of one. https://youtu.be/1QeSHLSwSXc?si=Df3eRCnkcoFWxfeE

Ducati caliper and 300mm Harley Flat Tracker disk rotor mounted on the XS650 disk carrier. I still have the front wheel for one of these Flat Trackers at home. Not that I ever had one, I just scored choice bits occasionally.

soon,, just some cables to do.



And to add to methanol discussion, a lot of the info applies on twostrokes also:

Can you remind me please?
Thank you

i never use google for search kb but others do they put kiwibiker in quotes "kiwibiker.co.nz" then search terms or images options

this took about 20 seconds

Use the Google "site:" search term to find all the posts about "balance factor" and how to check it posted on the ESE thread.
Copy and paste this line into your Google search bar:-

There are over 12,000 images attached to this thread and there is a lot of gold to be found there too.

To look through them use the "Thread Tools" option at the top of the page and then the "View Images" option.

Then they can be sorted by:-

"Posted Within" ........... I use from the "Beginning".
"Images Per Page" ....... and I prefer 70 images per page.
"Order Results" ............ and they can be in Descending or Ascending date order.

When you see a picture that interests, you can click on it to view it or click on the "N/A" symbol below it to go through to the original Post.

Thanks Husa. The Google site: search doesn't seem to work for me anymore. Don't know why. I don't need any naked pictures thanks.

No, it does not work for me either. I have been using the KiwiBiker "Search Thread" tool at the top right hand side of this page.

Turns out it runs a whole lot better when you wire the Ignitech up properly.

[wobbly]

So now Mr Hintz tell us what not to do - the important part.

Too embarrassing, can't say.

Apparently your embarrassment has scared us all, Neil; no one dares to post anything here anymore. Except for me, I'm too old to worry about losing face anyway .
