i was wondering how you know if you need a new top end or not. what are the symptoms that you notice while riding. also how long would it take to put in.

 

Do a compression test, thats the best way to tell if you need a top end. If you played with alot of legos as a kid you'll be able to pull it off in about 5-6 hours tops.

 

is there any other way to tell if you need new top end. i dont have the correct eqipment to do a compression test. you said that you think that it would take 5-6 hours. i thought it would only take only 1-2
so are you sure about the amount of time it will take.

 

oh ya its also a two stroke so would that change the amount of time to put it in

 

Im saying 5-6 because im not sure of your talent, that compression test is really the only way to do it that i know of, a compression tester is cheap, go pick one up and find out.

 

well i have done alot of engine work. i have done a car engine before. i have built up lots of car engines. i just dont know if this will be the same because its a two stroke and not as large as the car engines i have worked on.

 

its easier, your take the head and jug off, have that bored/ honed, install the piston onto the rod, then drop the jug over it, if you have mechanical talent you'll be fine. Just remember the arrow on the piston points to the exhaust. good luck.

 

Theres no way you give a time without at least knowing what bike it is. You could do a rebuild on a blaster in like a hour because its a air cooled single, but a 2 cylinder liquid cooled banshee might take a little longer.[img]i/expressions/face-icon-small-wink.gif[/img]

 

Just take it to the Yamaha Shop.

 

i dont feel like taking it to the shop becuase the ones around here are horrible they charge to much for labor and they are all D**kheads. yes it is a blaster like shavo said so you think i can do it in an hour.
