Thanks Roadtech. Maybe I'll get ahold of them and find out what they port to..But you're right, it is a little pricey inasmuch as I've got months to play with mine.... Manifold that is... And even if I do mess it up, it'* an extra one anyway.

That won't work. I'm putting the Bonne down for the winter. Stored off site and in one piece. Otherwise, that would be the best bet.

My human side showed. On an LIM side though..it'* amazing how much material can be cleaned up.

Reminds me of the old school castings etc that were X percent and that was acceptable to keep the costs low on the production.

Hi Barry,

"Looks" is the way to describe it. The way it felt was actually alot smoother. The looks were very decieving to be sure.
If anyone wants to get a second opinion PM Hawkjet -he has that ported LIM and is going to be putting it on in November IIRC.

No offense, Marty, but I don't see anything there that can't be done better in about an hours work.

DIY is definitely the way to go on something like this. There'* no reason to pay labor or a middle man.

The runners on that LIM are lacking a little attention to detail.

For some reason the pictures don't show up for me. But if they are photos of the LIM that I have, by the way people are talking, the photos don't do it justice!

No the ports aren't polished to a 16 finish, but I don't think they need to be either. Besides, I am not intending to race and I am not trying to eek out every .001% of performance. I suppose it is possible that another hour with some sand paper will make this prettier, but once it is installed, nobody will see it. I am quite happy with what I see here. I'd rather spend that hour installing it.

But like I say, I'm not a racer, so take my assessment for what ever you want...

EDIT:
The photos work now. And there is NO WAY the actual LIM is anything close to as bad as the photos look. The lighting doesn't show the port well at all. It is similar in concept to the scallop finish you might get with a 3D contour from a CNC machine. The reflections of this light would show that to be far worse than it actually is. It is unfortunate that the lighting has distracted the conversation. The manifold is just fine, really.

Marty: That looks really nice, but I do think I will do it myself. I have all winter, so why not? There is more satisfaction when you do it yourself. I was going to have a shop do the UIM and LIM work also, but I figured if I have the time, I'll give it a go for the same reason.

Will: Didn't you say in one of your posts that the polishing isn't that beneficial anyway? Just helps crud build-up. If that is the case, I'm not going to be overly concerned if the runners aren't as smooth as they possibly could be. There is probably a point of diminishing returns somewhere in that polishing. Thanks for all the comments. This forum is tremendous.
