My son bought a '97 zr440 yesterday, sled is mint but if you run it for a couple hundred yards it pulls really hard and then loses power big time, if you choke it, after a little bit, comes back to life and runs fine for a little bit again. Any ideas before I just tear into it? Just seems to run out of gas. Gonna be a lot of fun when we get it right.
