Well, don't hurry up too much. I still haven't even ordered the gasket set I need...and it is getting cold outside (-5c lately at night). I may have to get a move on if you are making progress :)
 
Can it be? I got a call today. My shiney new stainless steel valves are at the shop :D

I go out tomorrow night to see what is up and regroup on this.

saaz, did Bruce take you up on that pilot needle offer you made in his tech thread? If not I would like them if you are willing to sell them to me? I need them to rebuild the carbs I am working on right now for my Blue 78.

Rock on!
 
Mark, I haven't heard anything so let me know by PM what you want. All the jets and pilot air screws are ok bar one air screw that has a bent tip. At least they were ok back in the early 80s when last they were used!!
 
Well my Orient Express stainless steel valves are in. The head goes out Monday for some welding and to have the seats cut. Engine project is back on board :D

Whoever it was that recommended Orient Express, thank you.

PM sent. Thx man :)
 
I also have spare mag wheel sets and disks, but don't think I will send those to the US!!

Yeah I can understand that! :)

I shipped a GS head down to your island last year and it was choose between mildly expensive/very long ship time or extremely expensive/normal ship time.

The experience was not one that I enjoyed but I was asked to do it by a forum friend and therefore didn't mind helping. Shipping stuff should be easier.

As for my engine project here. The work to be done was already paid for too so there should be no further demons to pop up and stop this anymore. Let's hope it just gets done now. She is going to be wearing her old cloths for now when I get this engine done but finishing this step is the worst of it and then the entire project moves back into my realm of control so my next mod or appearance thread for this bike shouldn't go out two years long :roll: That was just ridiculous. I will be glad to see this come to an end. The joy was robbed out of it a long time ago :|


But it's still Rock on! :D

Oh, No.

This Means I really need to keep moving on Old Red.

(sort of hoping the guy calls to have me pick up the frame after blasting today, but I'm doubting it and if not it's ok, as I have enough to keep me busy on saturday)

ps. BTW WOOHOOO for Mark!!!!!!!!!! b :lol: :lol: :lol: :lol: :lol:
 
Sounds like another challange :lol:

Don't do it to me! Seems that's when something always comes up :roll:

I will just sit back and hope that you get your done before me bro :)

Shouldn't be too hard to do :?
 
Well progress continues to be made albeit slow. I am still being promised that this bike will run this year yet :roll:

Here is the latest.

Valve seats cut for the new SS valves:

It ain't much, but it makes it so that all that is left is assembly I think?
I have honestly lost track :lol:
 
Just wondering Mark and without reading back...with all this added power, are you having the crank welded and clutch basket modified/welded?
My simple mod's probably add about 15+HP and I thought it was a good idea to weld the crank and modify the clutch. In fact, V&H recommended the welded crank even if the bike stayed stock.

Good to hear.. I thought about it last night when I passed Papparo's at around 8:40 and they were packing the bikes away for the night.

Awww come on Keith, what? You don't want to read through all 31 pages to find your answer???? :twisted: It's in there :lol:




Yes buddy, were doing a lot including what you have mentioned. But I may enhance the clutch more later if it doesn't hold up. You can see the old list on the ninth post down on page 15 of this thread.

A reputable mechanic that Katman turned us onto says this engine built this way when setup properly should produce 120+ BHP but that is yet to be seen of course. I'll be happy with any number over 100. Anything under 100 and I have failed and waisted my money.

I need to enhance the brakes now 8O

I left there at 8:15 after picking up my jet kit. Brian was just pulling in.
 
I will be finishing the porting and setup of the head myself now.
I don't see any way this is going to get done if I keep waiting for
someone else to do it. At this point, I am aggressively retaking
ownership of my engine and my project. I don't want to ruffle any
feathers but if it happens so be it. I think I can do this? I know
Dink and a few others have said they do their own porting and
polishing work so I think I can do it too. I want this done!

Here goes!
 
Start porting and polishing without any experience or help? 8O !
Please Mark, if that's the case, just leave the head stock. You can lightly clean up any small imperfections but you have to do precise/matched work here. These bikes are a lot of fun with just pipe/pod/piston/mild cam mods. Be happy with that! :)

I agree, you have to know what your doing with PnP.
 
Well I appreciate that guys and I certainly don't expect any human to follow all 31 pages of this ridiculous thread to come up to speed but it is WAAAAAY to late for that. There is very little left stock on this motor anymore and it is more than medium modded at this point. The porting has already been done. ie... the guts were cut out of it and now there is some nice holes bored through into the other sides so it needs the patching (either weld or epoxy depending on location) and then will need finished with a flow/volume test to get them matched and then polished.

I actually know how to do it having studied it over the last year and a half and even performed the mod on one head already that worked out pretty good.

I may have misled you here. I won?t be doing anything without the help of a professional at a professional shop. It is staying right here where it is. It's simply that I have taken the project on myself and am "pushing" the buttons. So far I haven't angered anyone (choosing my words wisely) and have been told that I can do it and to come out and he will help as needed but I am finishing it now or it wont get done I am afraid. I don't see it getting done any other way. I didn't mean to make it sound like I am bringing it home or anything. I was just wound up when I posted that having just got back from there after a lenthy talk about "we NEED to get this done NOW! How are we going to do it?"

My presence is relentless at this point and my bike has been pulled from the back and moved to the front. I am being pushy, but careful. Sad ain't it? It's working. :|

I go out tomorrow after work to start my work. I can do it.
 
Open up a can of whoop-a$$ on this guy! We all will feel much better when you do!
