hmm, can get a new intake manifold on bikebandit for 86 bucks, i'm gonna make a cl ad for parts and see what i can get
Welp your already learning how to get parts for an old bike.
You need to find the OEM intake part # and do a google search on it.
Most likely it was used on more then 1 bike for example the IT250 uses it and prolly the DT250.
Use that info to hunt Ebay for one.
