excellent work done on the vario gear box :thumb

Maybe the CNC Alu triangle for the wheel bearing would be the I point to your great work.

Like to see the bearings in your fridge between the bread 😀
That is how it works, did you need much force to press the bearings in? How did you press them in?

ah, ok. If the engine is loosing power higher than 90°C I’m soothed. I only don’t want to damage the cylinder with the first try.;)

Maybe my thermo sensor is not the best as I made it by myself. I used a screw, drilled a hole through it and glued a sensor in it.
During engine run it showed ERROR, when I stopped the engine it showed the…[Lees meer]

oki, I will change to vario for next try. 😀

nejc93, thanks, maybe 144 main jet is a good starting point. Honestly, I do not know what jet is in the carb, just plug and play for the try run. :lol

What vario are you using on your race Bravo? Is it standard clutch or Fox clutch?

today I tried to start with pulley drive, but without decompression I had no chance. So starting again with drilling machine.

The thermo sensor only worked when the engine was switched off. Need to have a better one for the future. But water temp of about 79°C was not bad I think.

also the small fuel tank was leaking, nice smoke when…[Lees meer]

Andree, open for any proposal 😀

@ktmgek, I like to run it sometimes with race fuel (maybe for races)

https://ssl.dein-isp.net/rennbenzin.de/index.php?index=1&lng=de&menuid=6&ordner=shop.artikel-17-214

this can not be mixed with standard fuel. And as the race fuel is expensive I will have it under control with the small race tank.

update about cooling installation.

Thanks a lot, so far the Tiff is wayting for next spring or sommer.
I will leave it in original condition and plan to ride some tours and to meetings with it.

I’m sure that this will be a eye catcher as most of German people are not knowing that something like this was build.:D

Hi ritze, thanks for the info :thumb
So the akku will last longer than the fuel in my race tank. :haha

vespaAvanti, it looks that this pump is used in many Mercedes models, a copy from the web

für Mercedes Benz W202 W124 W210 W461 W463 Sprinter Vito Vaneo V-Klasse usw.

bitte vergleichen Sie die Pumpen!

thanks, yes, it keeps me busy 😀

ritze, yes, it is a Mercedes W210 pump. You have good eyes 😉

With what akku are you running your pump and how long is the akku working from full charge to empty?
I have a 2,2 AH akku, but do not know what the pump is pulling.

thanks :thumb

I changed the stuur from Cross style to more racing style 😀

also found a place for the coolwater pump

haha, after I got a complete disc brake set incl. orange 5 spoke wheels my color combi is very similar to that in the video.:D

next step will be a secondary coolwater pump from a Mercedes and a scooter radiator.

Nice, you know where it is relaxing 😀

didn’t find Enduro tires from Pirelli but from Heidenau, VeeRubber or…[Lees meer]

haha, yes the topic is old but still ongoing. 😀

Can’t remember where I got the tires from, need to check that if you are interested.

In the meantime I have put a Malossi RV block with a 50cc Athena cylinder in.

Here was the first drive test.

that’s why I’m asking 😀

Using in combination with inner rotor.

haha, yes, that is very sexy, I only was sitting next to it with a coffee for relaxing. :lol

I like the rear frame fixing, it fits perfect to the Ciao frame and is damped with two rubber washers.

I hope that I will get answer from Roost regarding a sprint silencer 😀

thanks for the comments.:thumb

Lennaert, maybe I will fix some 17″ wheels 😀

Lastpak, yes it’s a Roost 😉
For the next try I need to fix the cooling system, then I may can have the first roll out. 😀

thanks, for the first trial I’m happy so far 😀

Now I got the right exhaust for it

Edjuh, now we are at the peak. 😀

First short start without cooling water

Then filled water into the cylinder and had a longer try with very little throttle movement.

Andree, comming closer and closer. 😀

At my first starting trial one or two weeks ago the rotor was sticking to the carter when I used the drilling machine for starting.

Here some scratching marks inside the rotor. The result of this, no movement of the krukas anymore.:((

After turning the rotor inside a little deeper I had another…[Lees meer]
