Hello i got a 1985 iowa spree a little bit ago its in pretty good condition and runs but on a flat road i can barely get it over 15 mph. was wondering what i can do to make it go faster. also i would like to know what size air filter a spree needs and if you take off the air box and just have an air filter like a 1100f or r to make it run better.

Thanks-

d*** thats slow as *, the iowa sprees have a restricted exhaust, there is a washer in the headpipe. The airbox is also restricted.

Thats slow even for an Iowa. Probably something besides stock restrictions holding it back.
