Hi Guys, This Time i am coing To talk about my own scooter A yamaha Tmax 500 2003 model That is the earliest model with carbs I bought it from a garage engine non running and a nasty metal grinding noise when you crank it It turned up the timing chain and tensioner was worn out and the chain jumped Luckily no damage to the piston Just some really light dent But the valve were definitely dead as well as the valve guides I found a second head cylinder head from a bike who suffered house light fire damage And that s when my project started I originally fitted Malossi overrange kit Malossi higher gear kit with heavy duty transmission chain K&N air filter and Akrapovic full exhaust I enjoyed the bike with those mods for a year and last summer I fitted a set of malossi power cam Hear are the few pictures taken during the fitting
Getting ready to fit the cam The issue with those bikes they require specific spacer to adjust the valve play and the cam being different I had take be bike less for a week the time for me to order the correct parts and them to turn up Here is the engine with the cam cover off waiting for it internal organ transplant
blurgh i hate those valve shims, what a ball ache they can be sometimes. much prefer adjustable tappets.
