Anyway to patch or repair the intake boot between the air box and throttle body? Its on the nipple so its a stressed area of the rubber. Silicone or some way to weld rubber? Parts on back order and maybe for a bit just planning for worst case. Its on a street bike
Strange but you MIGHT be able to print one in NinjaFlex. They claim gas resistance but I would swap once OEM is available. Not sure what you are talking about the stress point the ones I have seen are tubes with stretch points on the ends. https://ninjatek.com/wp-content/uploads/2018/10/NinjaFlex_CR.pdf
I ended up using some silicone i had laying around. Cleaned it well with rubbing alcohol. I dont expect it to last but i was able to buy a whole airbox with boots off ebay. Hopefully that rubber last more than a few years...
