    Boots cracking and splitting after 4 months.

    Posted by Austin B. on 5th Aug 2019

    I bought this set to replace the factory pieces on my 73 CB500K (which had some very light cracks) at the end of April 2019. Installing them was a bear as the material is very stiff. I never was able to get the airbox boots to fit correctly as the factory ones did. Every time I would start to tighten the clamp, the boot would just slide off the end of the carb. It is now August and every boot now has cracks around them. I don't believe them to be leaking yet but I expected better. I've bought many of parts from 4into1 and they have always been good parts at a good price, but these are very disappointing. I honestly wish I still had the 45 year old original parts to put back on the bike.
