1988 1500 possable vacuum leak

Post by skip15 » Sun Jun 28, 2015 12:00 pm

My bike is surging and when try to take off it sounds like it's trying to pull air and then it takes off no problem at hi speeds just when taking off
there are so many vacuum lines i noticed on my wing do i have to take the carbs off to get to them all i have the air breather off and all the plastic on both sides can see alot of them but i don't no if i want to get into taking the carbs off because of all the tubing around them any
i also have a trigger wheel on the bike can these wear out and cause this

suggestions thanks

The trigger wheel does not wear out.It makes no physical contact with any stationary part.
Vacuum lines can be a bugger...especially the one that's under the carb.I found 7 vacuum lines in poor condition when mine was surging.
Simple age and use...They seem to deteriorate inside...especially at a sharp 90° bend...
So yes..the carbs have to come out to get to them all.
My first carb removal was 4 and a half hours just to get them out...A 2 day project...a few band aids...lots of coffee..2 trips to the store for tools... (extra long screwdrivers and needle nose)...another trip to NAPA with hose samples...etc,etc...
Then I found that the 88 carb just didn't do well..Another $50 For a accelerator pump kit and a month of mucking with it to fix the off idle stumble and it's finally running great...
There's lots of posts about surging and stumble in the "Search" section.
There's many things to read about and try.
