The operation of moving machine, or how to put a wider rear tire on the rear wheel, on the PX, of course.
I had to do it now, because of right kidney, VBA is 3 cm narrower then PX, so I had to fit the machine in chassis, to make right kidney big enough to acommodate px 200 machine.
To begin with, for wider tyre, you need wider rim. If on the standard rim is fitted wider tire, for example 100/90-10 or greater, due to too narrow rim comes to lateral protrusions / distortion of tire that scrapes on clutch cover. There are two inexpensive ways to expand rims. Or aluminum ring between the two halves of the PX rims , or two wider halves of PX rim, where on one half you have to close the valve hole. And then combine into a single wide rim.
For those who have tried to put a wider tire without moving the machine, they noticed that the rear tire is no longer in the center, but moved to the left (viewed from behind). This obviously means that if we want to bring back tire to the center, the machine should be moved to the right. And how much? For the dimension of 110/80-10 tire is enough to move 1 cm. Perhaps even stopped 120/70-10, but for her I'm not sure.
I have chosen 110/80-10 tire, just enough wider then 3,50-10 standard to looks juicier as I like. Not to say that the wet drifts are easier to catch, and the feeling of driving the curves is way better.
So, to perform the operation to start is good to have a new selenium blocks (thats how we call them, don't know why)
view on the bridge
To start I will cut one selenium exactly 1 cm
Since the pipe of selenium stretches out 5 mm from engine carrier, you should shorten the bridge only 7 mm, 2 mm more to have clearance between chassis and aluminum block
looks like this after cutting
Easiest way to put new selen blocks in the bridge is to push them with threaded bar and two wide washers and grease.
Look of "shortened" side
The other side, at the bottom can be seen the washer I made, exactly 1 cm thick, which I will plant on the right side
This is the way how it will be fitted
And this is the result:
