I just recently purchased my first bike ever about a month and a half ago! I'm very excited about it. Ive wanted a bike since i was a little kid. Its a 99 CR80R expert. I do know that two strokes require more maintenance then fours. I know how to do basic things like change the transmission oil and spark plugs. I just wanted to know if you guys could share some tips on how I can keep the two smokers engine running in tip top shape. Just simple maintenance that can keep my engine running strong and putting out as much power as possible. And also i was wondering how often I should replace the top and bottom end or if thats really necessary? I dont really have that much cash to be spending 1000's on my bike. So i'm hoping you guys can help me out. Thanks!
