リーナに導入するようにした。The above-mentioned tendency is particularly strong in motorcycles equipped with a cowling. For this reason, in the past, cool outside air was introduced into the air cleaner by opening an air intake in the front of the cowling, connecting it to a pipe attached to the bottom of the fuel tank using a rubber connecting pipe, and then leading it to the air cleaner inlet using a rubber conduit. I decided to do so.
