As installing CR carburetor on GS750, it is the essential part to avoid interference with stock camshaft chain tensioner.
It can also be used for GS400.
In order to build GS944, various small parts are needed, but unlike KAWASAKI Z and HONDA CB, there are no parts available for GS750.
If it is not there, I have no choice but to make it, and if I am going to make it, I want it to be something that I am satisfied with.
One of them, the prototype of the manual cam chain tensioner, has been completed, and we would like to introduce it to you today.
It does not mean that there is a problem with the stock cam chain tensioner, but when you try to install a racing carburetor such as CR or FCR, there will be a problem of interference.
It can be avoided by making the spigot as long as possible, but this will greatly impair the intake efficiency and response, and the gap between the carburetor and the engine will look awkward.
After spending all this extra money, the performance and appearance of the system will be inferior.
This is where a manual cam chain tensioner comes in handy, as it can be made compact.
Comparing the finished prototype with the stock one, the difference in size is overwhelming.
One of our specialties is the shape of the tip.
This is a faithful reproduction of the stock size.
Thought using a cap bolt and making the head of the cap bolt the tip of the bolt, but that's not quite right.
This shaft is made of chromoly and electroless nickel plating is applied on the surface, so it is not only rust proof but also has a great texture.
This is the reason why the tip shape is the same as stock.
The back of the slipper that is already used has this hit mark on it, so Factory Mameshiba wanted to make sure that it would hit here the same way.
If you disassemble the engine, you can replace the slipper, but the purpose of this manual cam chain tensioner is to avoid the interference when you install CR or FCR, so you can replace the tensioner only in most cases.
If you install the stock one on the cylinder, it will interfere with the float chamber of CR or FCR because it sticks out to the rear.
When the manual cam chain tensioner is installed on the cylinder, it will look like this.This can clear up the interference problem completely.
The outline is properly aligned.
Although it is almost invisible from the outside once it is installed, everybody may want it to be better.
As installing aftermarket racing carburetor on GS750, it is to be the essential part.
The anodized aluminum color is available in black or natural, please specify.
It is a simple structure, so it can be made inexpensively, but there is no point in making a new one if it only works.
The body is made of machined duralumin A2017 by machining center.
The shaft is also made of machined chromoly.
The surface treatment to maintain the rust resistance and texture is also not neglected.
The adjustment method is simple.
Fit the manual cam chain tensioner to the cylinder.
Remove the spark plug and points cover.
Then, while slowly turning the crankshaft in the forward direction, screw in the tensioner bolt with your fingers.
Then, you should feel the tip hitting the back of the slipper, and slowly tighten the slipper as far as you can with your fingers.
Then, by turning the crankshaft in the opposite direction, it can be tightened further.
Tighten it up to the point where you can tighten it with your fingertips, repeating the regular and reverse rotation several times.
Then, back off about a quarter turn to release the tension a little and fix the lock nut.
It's easy
Also, it is not something to be so nervous about, so anyone can do it easily.
