I'm trying to help a friend with his 1988 1500. It seems like it is runing on 4 or 5 - more noticable at idle. It stumbles bad on take off and acceleration. At first is was thinking carb. problems, but after riding it for a while, it seems to do it most of the time - hign or low rpms. I checked as many vacuum lines that i could reach and all are good. I would like to do a compression check, but it shure looks like a big job. What do I have to remove to do the compression test? If I do end up going into the carbs any suggestions? What about timing belts? Could one be getting bad and runing loose. What is the procedure for troubleshooting?
Thanks for any help
