How are all the Tmax fevers holding up these days?

I have a confession. I really miss riding my Tmax.

Last August I rode her into Houston traffic on a _really hot day. She started putting out white smoke. I have been in denial and despair since then. She's been a garage queen for past year.

So yeah, I fully expect there to be a cracked cylinder wall. I really have no near plans to rip it all apart to check atm. But sometime soon I suspect I will change my mind.

Anyways, about the fever I've been looking over some things and realized I might start adding ZDDP to my scooter oil. Thinking about messing with those bucket tappets has made me wonder if this wouldn't help reduce the running temperatures enough to have the coolant perform reliably and get more service life out of the valves so I don't have a repeat of a cracked valve every 35k miles or so.

wish me luck! Dx

Hope everyone is happy and healthy in these scooter-needed times

As I remember the "TMax Fever" was always about the fuel pump overheating. Nothing to do with the engine temperature.

I experienced the fever years ago and changed out the fuel pump with the same one that BigWheelsTurning had recommended. I haven't add any sort of no-start issue since then.

Good luck!

Nah I live in a really hot place. its just poorly designed for cooling. although I think additives could be used to stabilize temps on the fluids.

What I really want to know is if any of the mod'ers have tried adding a water-methanol injection system for the T-Max.

I suspect that could offload alot of issues.

Replacing the fuel pump worked for me.

I got TMF right at 4000 miles. Replaced pump. Haven't had it since, with 42000 miles on it.
