Hello everyone, last year I started with refurbishing a MT 350 Harley from 1996 and got a license plate at the beginning of November this year. I think it is a very tough engine and my intention is to regularly withdraw into the woods and the countryside.
The carburetor of the engine seems to me out of order and so I am investigating how I can repair this.
Some technical advice from expert would be welcome and that is one of the reasons to join this club.
In the Netherlands there are not that many owners of a MT 350

Welcome to the forum

The Keihin carb is fitted to the MT350 problems often found are
- clogged up jets and internal passages. Clean all jets and the hole through to the enrichener
. Remove jets and clean them. Use thin wire to clear passages You may have to remove a thin soft blanking plate . You may want to have the carb cleaned ultrasonically
- accelerator pump diaphram cracked or hard, replace it
- diaphram torn or weak, replace it
-rubber hoses to and from carb cracked or split

Top tip- replace standard No 40 pilot with a No 42
Drill larger hole to allow more air to flow.
Have a look through the forum Technical section or Google ' Keihin carbs' to find video clips

Cables dry out and stick, renew cables if the throttle doesn't open smoothly

The mixture is set weak, you can adjust it 1/8 turn at a time to find best setting

If airbox has had extra holes drilled in it, tape them up

Check cambelt is correctly set. The engine will run if one or even two teeth out, but it will not pull strongly

Once cleaned the standard carb is reliable. Some owners do fit other carbs

Have a good look through the forum Carburettor section
Good luck

Hi Roadking,

Welcome to the forum, hope you get your bike running properly soon, Your nearest Harley Davidson dealer should have carb spares in stock as they use the same carb on their big V twins.

We offer a dellorto carb replacement if you're after something a bit more conventional and responsive.

Welcome to the club, Roadking,
Nice to see a new Dutch MT-owner on this site. There are at least 11 active MT-owners in the Netherlands. Not bad for such a small country.
I buy most parts in the UK
