Yamaha TT350 Top End Rebuild 

Thank you for taking the time to make this video, I learned a lot from it and was able to rebuild my own top end on an 1998 xt 350 which is running awesome now.

thoes little rubber seals u put on the cam cover bolts are the valve stem seals

thos little rubber seals are valve guide seals.. the kit comes with 4 seals one for each valve.. LOL.. the not for the valve cover bolts..

Yew beauty I've been looking everywhere for how to line the timing up! Had no idea about the marks on the magneto and casing. Moines probably to dirty to see lol

i got it now:)!!! was a new junk head gasket!! it was letting oil pour into the combustion chamber... at least now i know how to build a mosquito fogger!! lol it runs great now.... cant wait to hit the forest on thursday...

Athose little plastic things you stuck on the bolts are valve stem seals champion .

Hmmm. My first thought are have you got the rings in the right position? the gap in the rings should be either diagonally opposite or at 45 degrees from each other. The oil ring maybe faces back.... It has been a while since I did it. I remember going to my local yamaha dealer with the piston and rings and talking to one of the mechanics

Did you change the jetting for that pipe?

Will this video also apply to an xt350 motor? I have to rebuild the top end on mine

little plastic picec you didnt know are valve stam seels. (remove valvesprings to change (big bar clamp and simple modified, cheep sparkplugkey) if pistonrings and zylinderheadgasket are new or good but engine is stil burning oil. better save that time for riding if not nessesary^^

can you tell me again what you did to the muffler i didnt understand but thats great, do you notice a power difference

6:40 those are valve guide seals

so i just got my tt350 togather tonight.... and it smokes like hell... white smoke..... rings are new and i dont think a valve seal could leak that much oil.... idk... any ideas??

oh my god brother please do not tell me you really believe that those green little rubber things going on boats please don't tell me that please disassemble. Motor right now and fix that please

Hey did you solve the leak on the rocker cover gasket ?

ey ermano yo tengo una moto igal pero no tengo las refacciones me podrias ayudar , es el piston, biela , perno, candados, anillos, no se si me puedas consegir un contacto..gracias
