Didn't work for me too.. Make attempt several time but never been accepted. My name on Fb is Dany Boutin

Which dealer do you recommand to buy my gasket kit, seal kit etc for the rebuilt ??? I know Tony Doukas, which one else ???

Ok maybe you are right, I dont have lots of xp in porting but I was supposing that the exh dropped to BDC will help flow and fill the combustion chamber with more fresh air/fuel... Correct me if i'm wrong..

Thanks for the blow down description. Yess I didn't mesure before because I was throwing a 4mill crank on it but as soon as I rebuilt I will do all the mesurement and work from there on the next port job depending on how the bike run.

What I did is to cut the base to make it perfect fit to the transfert on the base of the jug. I PM you, I want to know as much as I can on porting !!!

What do you mean by blow down ? Exhaust port duration ??

I have a stroker crank so the exh need to be dropped too

Transfert are dropped to BDC and are matched to the case. I worked every little detail I saw that could make air flow better. Since I want a trail bike setup with lots of midrange I did not raise any port. The job are not completly finish yet, I'm looking to widen the port a bit. I was also trying to figure out if I should open up the intake port a bit but I think my best bet would be to just work the upper part a bit to improve flow... What do you think ?

For info, how much hp and tq a stock banshee with T5 will reach ?

I matched all transfert port to the base, 4x boost port, chamfer where needed, dropped transfert and exhaust port to BDC and matched to the T5 pipe. Cool head 24cc, 135 psi on pump gaz. .052 squish. PWK 33mm with 2x K&N Pods + 2 brand new VF4.

I would guess that a 4mil get more that 40-45hp and 8100 rpm... But 30+tq that would be real nice for a trail bike on tight trail I'll let you know how I like it but I can't put it on a dyno as the only one I know is 200 miles from here...

Here a pics of the jug I currently port for my 4 mill stroker longrod with T5 pipe. Tell me what you think.

Yes I have a 4mill longrod crank and there is a thick .080 head gasket sold at Bansheedepot.com that give the extra clearance to the head chamber to run your stock head or stock dome without milling but it's also true that it's a shitty way to built a 4mill so i'll get my dome cut tomorrow Thanks for the help I order this plate cause I wanted to test it and see how it goes but when I take my squish this morning I thought it was way too much so I get scared and ask here
