1985 TRX125 top end questions
I picked up a complete '85 TRX125 at a scrapyard for $100. Figured I could always part it and make money. Anyway got it home, squirted some starting fluid into the spark plug and she fired right up with the rope (no battery). Put gas in and she ran great, until I saw all the black smoke.Went through all the gears fine so I decided it was a keeper. So I took the top end off and took it to my local bike/atv dealer who ordered a new gasket set, Honda brand rings ($$$!!!) and valve seals. There is some fine scoring on the piston, but they said that it was just from dirt going down the bore and that the piston was still within specs and usable. They honed the bore and put in new valve seals and off I went. My question concerns the base gasket for the jug - the new one is just a fiber gasket, while the OEM was steel with a fiber coating. Am I supposed to scrape the fiber off the old steel, or do I remove and toss the whole affair? The steel/fiber unit seems thicker to me, that's why I ask. Plus I damaged a small area of it working a putty knife in there on removal. Any help is appreciated. Cheers!
