4mil crank install

[Relytt58]

alright so i have an 03 banshee and can get a 4mil hot rods crank for close to nothing from a buddy who got it in a trade, the crank is brand new. I was wondering how hard it is to put the crank in. i know that i can bring it in and have it done but i prefer to work on my own stuff. i can do pretty much everything else as far as working on it but i've never done a crank

you have to split the cases. if you don't have the port work for it i wouldn't even waste your time

Yeah, you will be very happy if you get your cylinders done before installing that crank, well worth the money! :thumbsup:

alright so how hard is it to split the cases? ive done it on dirt bikes but never on a banshee. i was planing on geting them ported before i did the crank.

I don't think it is hard. If you have done a two stroke before, then you should have no problems. Just read through the manual and follow the steps. I think BigRed350X has a case splitting guide, I will try and find it.

 

Here it is: Splitting the Cases

 

Hope that helps! :smile:

thank you guys so much the guide looks preatty easy i have not done a 2 stroke but it looks alot easier then my 4 stroke bike. i will pick up the crank tomorrow but will wait to put it in until i get a port job. who should i go thru on the port job? i dont have much money so i good cheap job would be ideal. i mostly run out in the dunes with some drag racing.

BigRed350X definitly makes it look easy

i just had a 4 mil put in mine and i was told you had to get a stroker plate on stock cylinders.

who ever told you that is a dumbass. the plate is about the worst route you can go, it give your motor more places to leak and blow that thing up. your best bet is to get a cool head and cut the domes for the stroker. then have your jugs ported for te new crank to match the porting timings

yea avoid the plate if possible.
