This is a very helpful item. This is a set of 4 new Valve Guide Seals for the Honda XL250 and XL350 and TL250 from the 1970's This is enough for 1 engine. 2 exhaust and 2 intake. Important part of a top -end rebuild. We also have other items in our ebay store for these bikes too! Top quality aftermarket item. Part #12209-333-005. That is it! Good Luck! Thank you!
