Carb O-ring Sizes
Posted: Tue Jul 03, 2012 2:43 pm
Wondering if this could be made a sticky or similar?
Just to say that the other day I replaced all of the o-rings in my carbs. Bike runs sweet and all is well. They may not be the exact sizes but are as close as I could get. Had problems getting a good size for the two on the float but I managed it and the others aren't majorly critical anyway.
So sizes are as follows:
- 3 x 1 Mixture Screw O-Ring
- 4 x 1 Top Vacuum O-Ring
- 10 x 1.5 O-Ring between body and slide holder (white piece)
- 6.09 x 1.78 Larger O-Ring on float assembly
- 3.69 x 1.78 Smaller O-ring on float assembly
The smaller one needs a bit of lubrication to get on but then its a nice snug fit.
As a side note, you should try and get all of the o-rings in Viton (maybe not the vacuum one). It is much more resistant to petrol that normal Nitrile o-rings.
Hope that helps!
