Changed carb rubber
TZR125 Track Bike
When investigating the carb rubber, it looks like it can be improved.
I like to remove the boostbottle because its there for improvement in the low rpm and may cost you at high rpm.
Also like to angular the flow more.

The oem carb rubber.
The big boostbottle hole.
Machining the plug.
Not a big challenge, but nice to do
It fits like a glove
And already giving a nice flow
To give the flow more room I cut the top and bottom
This creates a huge duct that needs to be smoothen out.
After a lot off cutting and grinding it start to looks promising
As you can see the duckt is completely smoothen out.
Will be interesting to see what it does.

Compared with the oem one, looks like the mod could help the engine a bid.
