The higher pressure cap stopped my overflow from becoming pressurized and blowing out. I did a combustion gas test on the cooing system and it passed all 3 times, so it made since the factory cap was to low of a rating for serve duty.
The internet provides many options. Not all are good. HHR provides top notch customer service and the best parts available.
quick shipper
awesome customer service
I ordered Avio fiber glass fairing and all necessary brackets for 2023 Yamaha r1. HHR answered all my questions by email and later by phone. The staff I communicated with were knowledgeable, straightforward, helpful, and non-judgmental. I've had been using the products for more than a year, and I have no complaints and am quite happy with it. I've heard it's easy to installl, too, but I had someone else do it, so I can't say if that's true. The bodywork has cutouts for the tail light and headlights. Works great.
