hey guys i just need a bit of help in choosing the direction to go in...

 

well my mate just bought a banshee that was appenetly running but had no power due to low compression..

 

the mechanic told him it just needs a top end rebuild... my mate asked me if i can rebuild it for him and i agreed, but how do i

 

know that the pistons just need replacing???? im worried i will rebuild the top end and next thing u no the crankshaft shit itself

 

how can i check the crankshaft while the engine is still mounted to the bike???

 

this will be my first banshee rebuild.. im very confident but wanna do everything 120% so if u all can give me any helpful tips

 

it will be much appreciated

 

thanks for your replys

Get a Clymers manual. It gives all wear tolerances of crank. Should be able to at least check side clearance of big end, small end free play.

Get a manual!! It has step by step instructions and helpfull tips. Also, I would take the extra effort and pull the entire motor out of the frame. It only take about 15 more minutes and it make working on it alot easier. So first things first, BUY A MANUAL! Then drain the fluids out and pull the motor out of the bike. Then pull the topend off and take it to a shop to have it either honed or bored. Then you will know what pistons to buy. Then follow the instructions in your manual to reassemble.

thanks guys... ok i already have a cylmer manual... so its suggested to spiltt the crankcase and check the crankshaft properly

 

im also not sure of wat pistons to buy? this topic has proberbly been covered 100X but should i go for cast(proX) or forged (wiseco)

 

i would personally choose forged but dont really know the advantages .. thanks
