Hi, I am new here and this is my first post.
I have a 1990 venture royale that just turned over 40,000 miles. It was working very well until recently, but now it is revving too high and, in addition, I have to manually turn the throttle back to slow the RPMs down (i.e.: it does not go back if I just release it).
I have been told that I have two problems: 1) I need a new throttle cable, and 2) I have some kind of vacuum leak.
Then they tell me that since it is a very old bike, they can not give me an estimate of what it will take to fix it because once they start probing all the little connectors near the carb they may fall apart and it may take an undeterminable amount of time (labor) plus time (elapsed) while looking for whatever parts may be needed.
I realize that it is true that without a magic ball it may be impossible to come up with an accurate estimate, but I would like to have an idea of some likely range, specially the upper bound.
Any ideas on realistic cost in terms of 1) availability and cost of parts that are likely to be needed and 2) number of labor hours involved?
I thank you in advance for any light you may shed on the subject
