I need a complete gasket set for my 86 ATC 250R. Where is the best place to buy and what brand do you recommend?

 

For an aftermarket gasket set, I have had best luck with Vesrah brand gasket sets. I have used Athena, Windersosa (top end sets only), and Cycle Craft gasket sets, but they tend to leave out certain minor gaskets from their sets. Look to pay between $50-60 for a complete set if you can find an independant shop that can get you the gaskets.
You might ask Vince at www.vincescycle.com - he seems to have reasonable pricing, even for his OEM parts.

 

www.calatv.com has complete honda set for 40 plus shipping. i have yet to find a better price/
