how many miles before an EVO needs a overhaul? Topend or both?

 

Really cannot answer that question. All depends on maintainence and how it was rode. There are lots of factors in here....

I had a 1984 FXRT and it had approx. 89,000 miles on it. The only thing it needed was cylinder base gaskets though. The bore, heads, and top end were in great shape. I put it all back together and rode another 20,000 miles and then sold it.

The EVO can last a verrrrrrry long time!

 

like evorider said, depends on how it was maintained. ride it until it starts smoking.

 

Treat it right and 100,000+

 

I will second that.

 

I know a bro who regularly beats his Evo FatBoy like he stole it and it has over 40K same rear belt and pulley's even.

 

Got over 100k on my FXR when I sold it.Replaced the base gaskets, Head Gaskets and rocker box gaskets at 60k and that was it.

Have 29k on my FLHT and expect to get over 100k before it gets rebuilt.

 

My 93 was rebuilt (top end) at 50 k. Today, at 76k it runs fine, but does burn about a quart per 1500 miles or so. Depends on how hard I twist the throttle.

 

My 85 has about 65K and still strong. I am thinking of punching it out. It does not need it, but I am bored.

 

Ran 76,000 miles on my 99 EVO before I sold it.Installed an oil cooler and ranM-onesynthetic changed every 2500 miles or under. Basically, I never let the oil get dirty which is the 1st commandment of owning British bikes for several years.No mechanical issues with the engine whatsoever.I'd swear the bike ran just as goodas the day I bought it.
