For sure!
do you want a race type set up or a daily driver? There is a HUGE difference.
Read the SPI post in the General section as well. You'll save big $$$'s, and get the good stuff. Don't even bother w/ Ebay sh** for your 2t engine.
for a complete rebuild (pipe/carb/bbk/cvt components/intake tract) plan on 500.00 ish You can work down from that, and buy/install in phases.
For an old inefficient 2t design these dio based engines can produce up to 25HP, and reach 100MPH.
For a daily driver 60+ is respectable. My daily tops 70MPH but I don't ride it anymore... 6-7 years of modding it just lost the charm.
