each time i touched that filter it had more holes.
yes the yellow one has fiberglass fenders and a steel front. the red one the rear fenders were broken so i got those Orange 72 style fenders from Larry's we all went to for $30. they were over at his house
they are both 1970's
the red one i got $167 on ebay. new plug and new fuel lines and it fired rite up. rear axle assembly is from a 1980 110 to use the big red hubs and wheels with the stock Warroir tires. they cost $100. so grand total for running trike $275 after new filter.
the yellow one i got for $120 from the same guy a while later. did not run so i got a running 76 on ebay for $75 and stuck all the wheels/axle assembly and motor in the yellow chssis for the old school look.
