So I want to pull the head apart and make a full parts list to do the valves and possibly piston (i.e. is the intake rocker arm bent? Is the cam ok, is the piston worn?)
The TW is my only ride and this might sound crazy but I’m wondering since it’s running good other than valve noise, can I pull it apart, asses the damage and make a proper parts list and put it back together with the same gaskets that are on it and be ok for week of short rides to and from jobs?
If I had another way to get around I would just tear into it, but right now jobs equal fixing the bike properly.
Also if I want to do the valves and guides my self will I be able to put in new guides without the fancy tools that you can’t order anyway? What about reaming the new guide?
I already got one fancy valve spring compressor 😉 i.e. c clamp from Ace.
I’m ok with having a shop do the guides and even installing the valves.
The valves tips are worn and noisy and it appears that either a valve is bent or a rocker arm is. The base gasket is leaking. And I am finding metal flakes or rather thin small flakes with one side metallic and one side black in the oil filter.
I’m concerned mostly that if I don’t fix issues preemptively I’ll find my self stranded.
Yes the engine did run “low” on oil for sometime previous to me having it due to the wrong oil filter. I had a new cam, cam chain, piston and rings put in about 7k miles ago but as far as i know the valves are original.
It has15,000 on it.

I might have found a solution. Or possibly more problems lol. I just looked at a “basket case” as my Dad put it. 2004 wr250f in a box. Needs radiators, rear sprocket and chain, and head bearings. But it’s $100... was running before torn apart to ship. Guy bought it while he was on island then tore apart to send home but due to regulations couldn’t ship it out. It’s been sitting for a year so carb will need work.
I was thinking run mine till I get the wr together and then have a way around while I tear the tw down.
I reuse gaskets all the time. I was taking things apart enough if I used new gaskets every time I would be in the poor house. I haven't had any troubles as long as the gasket doesn't tear. A small tear can be patched with a little teeny bit of silicon gasket maker but big tears need a new gasket. The head gasket seem OK to re use. Zero problems doing it.
Every time I look at my oil filter I find little bits of metal. All those moving parts and shifting gears there is bound to be some shrapnel created. The filter is there to trap it. One bike is 32,000 and the other is 24,000 miles.

Long live the internal combustion engine!
That’s how I got the TW actually. I was given a scooter in disrepair. I spent some time and a little money got it running and flipped it and used that to start the obsession haha!
