I've moved on my Zeal 250 project to concentrate on my ZR-7. I bought a new K&N YA-4085 air filter for the Zeal but it sold before the filter arrived. Please research fit yourself to make sure you agree it will fit Zeal. I based it on the YA-4085 fitting the 88-90 FZR400 which lists the oem filter as 3TJ-14451-00 (same as the Zeal). May fit some FZR 250s but I have not checked. $50 for the air filter. I'm happy to post it in Australia at buyer's expense. Thanks Terry
