New member with Gilera B300

Postby roadster » Wed Nov 05, 2014 12:27 pm

Hello all,
Sorry for not speaking germany. I am from czech republic but english is better for me. I just bought giute complete Gilera B300 second serie. It is not in original condition. Has another mufflers and seat but I like it as it is. At first, I have two question:
1. Identification: engine and frame number is *31*60xx. Can anybody tell which year it is?

2. Problem with parts: Is there any shop with replica parts? At first I need complete oil filter body. There is nothing in my gilera between drain plug and oil pump. Or can anybody help me with an idea of solution?

Than You very much

The Gilera should have negative earth. My Gilera 150 also has negative earth.

Hello All,
I started to work on my Gilera B300 second serie engine. Main issue is gearbox. Only top and bottom gears worked. Second and third did not. I was not able to shift second gear and third gear was plucking. So I reassembled engine. See attached pictures please. My questions:
1. in picture 1., there are main problems. Gear selector is damaged because of there was contious pressure from this selector to gear. Do You thing that problem is in bad position of gear selector holder?
2. in picture 2., there is my gear selector. The good one. Is this right part for my Gilera? I saw different type of selector on other gileras on the internet. But those gileras had also different gear to connect with this selector. I am little bit confused also because there is not radius.
3. in picture 3., there are shafts from gearbox with gaps. In my opinion these gaps are too big. What do You thing?

Thak You very much
