Hi i have a 2001 yamaha r1 i am installing a engine that i did not take out i was wondering if anyone could help me with figuring out the vacume lines off the carbs i cant seem to find were they go and i think im missing some lines thanks
SOURCE: vacum and fuel line diagram needed
I have the connection shematics.
I'll try to explain, if needed send me your mail address, I'll send you a drawing.
First, the elements and their amount:
- 1 rollover valve, 2 straight connections.
- 1 Canister, 2 connections at the top, 1 outlet at the bottom
- 2 5-way connectors
- 4 Vacuum control valves, 2 connections at the top, 1 at the bottom
- 1 fuel tank, 3 connections, 1 is the surge hose connection, 2 others on the fuel ****: 1 fuel hose, 1 vacuum hose
- 4 carburettors: Seen from the back: 1 fuel inlet on a common ramp at the back, 1 vacuum connection between the two center carbs, 2 ventilation hoses at the outside of both center carbs, 4 purge hoses, 1 on the air filter side of each carb ( at the center of each external carbs ), 1 connector on the most left carb at the front bottom.
Now, the connections:
- 1 hose from the fuel tank surge hose connection to the roll-over valve, air must go from the tank trough the roll-over valve
- 1 hose from the roll over valve to the center upper connection of the canister.
- 1 hose from the second upper outlet of the canister to a 5-way connector.
- The third connection of the canister must stay free ( fresh air inlet )
- 4 hoses from this 5 way connector, 1 hose to each vacuum control valve at the upper 'side' connection
- 1 hose from each upper center connection of each vacuum control valve to each carburettor purge connections.
- The bottom connections of each vacuum control valve must be connected to the other 5-way connector.
- The main gallery of this 5-way connector must then be connected to the bottom front connection on the left carb.
I hope you've understood the explanation and you are helped.
The 1989 model is different ( it has a canister with 4 connections and only 2 control valves )
