Hey guys , I believe I need to change the 4 carb intake boots on my '88, they're still original, while I can't seem to find any vacuum leaks on them with the spray test , the bike seems to act like it has a small one, I have noticed some seapage around them , particularly near the carb bases. My questions are do I need to or should I change the vboost cross over boots too? and if so where can I get a reasonable price on these parts , and do I need to remove the Intake manifols to change the VBoost rubbers, and would I need any gasket for the intake manifolds also?
