My '82 XJ750 "Project Shadow Warrior"

So I've been scratching my head....Has anyone ever swapped or tried a xs1100 tank on the xj750? It is more straight on the bottom. I know it would need to be modification. Also, I'm aware that a 650 secs tank will fit. I just want to know if it's a lot bigger is overall size, look funny? It has almost double capacity on it. A side by side comparison would be nice if there is one out there? The 78-79 version is the one That I'm contemplating. I think that the top tube might have too steep of an arc and it would hit the top of the motor? Is the xs1100 frame more gradual in the top tube? I'll post a pic of the tank and the look I'm after below.

 

I saw on another forum a xs750 tank test fitted on a XJ750 Maxim. It road high on the frame. My question is, can it be fitted lower on the frame to look straight or would it need a lot of fabrication? A little isn't bad, just not reconstruction. Has anyone attempted this successfully? I'm wondering how it looks before I get one.

 

How did you get that nice shine in the motor. In the pictures at the beginning of the thread? Did you get the motor bead shot?

 

No, I used POR-20 Aluminum high temp paint. this stuff is amazing!

Update date on Project " Shadow Warrior"

I just recently purchased a few items for the project. I think these will real transform the bike. I'm sending the triple tree into Classified Motto to adapt it for the maxim. We'll see about the tank and it's fit. I'm looking for a R6 wheel and brake system now to finish the front end.

XS750 Tank

 

So I decided to go all out and do this bike the right way. I removed the engine and left it as a rolling chassis. Getting the motor out WAS A PAIN IN THE ASS! I'll admit, I did it by myself and the first time doing it. I rigged up a strap system from the rafters of my garage and lowered the bike on the lift. After hundreds of different configurations, it was evident that I needed to remove the oil filter cover off the engine and remove the rear swing arm for it to come out of the frame. There was just no other way. The only problem was the dam bolt was frozen inside and I could not get it loose. I ended up grinding the bolt head off with a grinder destroying the oil cover with it. Oh well, I guess I'll have to add that to the list of parts. Other than that, it was not that bad. I also just received the XS750 tank and just test fitted it. It rides a little high and back. This is due to the mounts on the tank & bike interfering. I think it really changes the look of the bike and looks way better than the Seca tank imo. Now I'm just waiting for the R6 forks to come in the mail this week. This bike should start to look pretty sweet soon!

 

My R6 forks just came in! Now they are off to Classified Motto for the triple tree mod. Should be back in a few weeks.

 

Ok, time for an update on Project "Shadow Warrior." It's been a while and I have done a few cool mods I hope you guys like? I found a great shop in Richmond, Va called Classified Motto. They do front fork converstions. I sent them a R6 triple tree with my bike's origional and they combined the two to fit a r6 front end on my bike. I have to say this thing makes the bike look sick. It's sort of Cafe-ish, but with more of a sportbike twist! I put a XS750 tank('77) and gold adjustable shocks from ebay. I also had a custom seat that was handmade in England. There is a lot more to do and I'll be updating this as I go.

 

Lookin' NICE!!!

Gorgeous! Any plans for the real wheel?

 

That looks fantastic, did they just have to swap out the bearings for the fork to fit?

What did it take to make the tank fit?

 

I wanted to put a sport tire on the back but the driveshaft limits my options. I really thought hard about converting to chain drive, but it looks impossible? Is there one guy out there that did it? I don't care how impractical it is, that's what custom is! In reality, I'll match up the front tire with a biased like the rear. I think a 110/90r17 tire or 120? I like the Michelin commander 2 tire. Does anyone know of a high performance biased tire for a set?

 

I sent the xj750 triple tree & the r6 triple tree into Classified motto. They mated the r6 triple tree with the xj's to fit the neck on the xj. I was able to use xj750 bearings. The conversion is around 450. I was very happy with the service & highly recommend them!

 

I just purchased a set of rearsets from fastfromthepast.com. I got the xj650 set. it looks like they should match up to the Maxim mounts? Will see, I get them in a few days.

 

Keep your eyes peeled,I'm fitting a 240 tyre into a 650 frame running a 900 engine with the shaft drive..... :wink:

 

I'll be really interested in seeing how you did this!! Please include detailed photos of the progress. I think there is a bunch of guys on here that are really excited to hear if this can be done!

 

This is going to be a sick bike when you finish. Can't wait.

 

What is it that they actually do to the forks to get them to jive with the XJ frame neck?

 

I'd guess at swap the stems and make up spacers to accomodate the top yoke. Pretty easy if you have access to a machine shop,done loads of them.

 

well, I got them in and they were very different. Oh well, I guess some you guys knew this already. I just gave it a shot. They have good service there and I'll be exchanging them for some universal ones. I'll say these are some awesome rearsets! If you have a Seca, They would look badass on your bike!
