awww taken the easy way out,i assume you are having him do the porting also
We havn't discussed porting yet. Ya, I guess it is the easy way out for sure. If I could find a press to borrow, I'd go for it, but I just cant see myself ever needing it again.
Looking at the case, Im not comfortable with taking any material off that will leave an edge to score the blades either. The tolerances are pretty tight.
He never talked to me about that so he must still be planning on doing it himself before he sends the unit to me.
EDIT: Ooooor not at all. lol
Id never be able to show my face on this forum again if I didn't do something for porting.
haha, yup. I'd tease too.
I hear you, that the gain in power per dollar isn't huge, and it is still time spent that needs to be accounted for.
I'm still on the fence. Part of what we are doing here is learning by doing ourselves. Ugh. Decisions. It will come down to the cost of shipping. If shipping makes costs the same as buying the press, I'll buy the press. Even if I take it apart and store it after.
I think I can do a basic port/clean up on the casing. From the documents Rocket sent me (Thank you Rocket!) the real power gain is on the inlet side. It looks like if I port the top side of the inlet, that helps quite a bit. Also, on the outlet, Just taking care of those two screw casting protrusions, and radiusing the edges and smoothing them out helps.
I definitely appreciate Rockets honesty on all levels, and want to thank him for that. Thanks Rocket!
High volume fuel pump. Check one off the list.
No fun. I couldn't get the fuel line off. I was able to get the assembly out of the fuel tank with some maneuvering and replace the pump. Im glad its done.
Here it is.
I couldn't do much on the intake side unless I want to work with the intake manifold also.
On the exit, the only area that could touch the blades I changed was at where I changed the bolt housing.
Other than that, I just radius'd the edges out. Here's a couple pics.
I think my M90 is too old to have a epoxy coating on the blades. I don't see any coating at all.
The walls of the case are a bit scored up, but I don't want to touch the walls at all, as this will remove material and increase the gap between the blades and the case.
The scoring isn't too bad. I see far worse pictures on the net (For what that's worth).
Mine had no carbon on it at all. I don't know the history of it though. I do know that the last time the snout was taken off, no sealing material was used on re-assembly though. Maybe it was cleaned, new oil fill, and not used?
