H2C Carb Oil Feed Questions
Posted: Sun Aug 24, 2025 5:08 pm
Hi All.
A couple of questions regardiing the H2C specific oil feed to the carb bowls:
1. The parts book I have does have a section near the back, listing H2C specific parts. It even shows a drawing with the oil pump to engine pipes but the part numbers listed are the same as the H2B and the drawing is the same as the more detailed one further forward in the book, in the H2B section. So what I am after is the correct part numbers for the banjo bolts seals where they screw into the carb bowl, or are they the same as the H2B?
2. When you go through some carb maintenance, maybe Ivan's jet kit fitting, you refit the carbs with empty bowls. Then using prime on the tap you can get the bowls full of petrol, but what about the oil - does this mean you risk the first start with no oil in the bowls? Do you put a couple of shots of oil in the bowl before connecting the petrol lines?
3. Suppose this goes back to the oil valve shut-off in the oil pump feed line story, but do people have trouble after leaving the bike for a while, with the bowls filling up with oil, especially with these lower viscosity 2 stroke oils around now?
Thanks. Just after a bit of advice from the people who know!
