XJ Bobber project, general questions

The problem isn't whether or not you want to spray crap all over the front of your bike or not; that's a matter of choice. At issue is the loss of the fork brace. Not something to recommend.

Yamaha has installed a fork brace on their street bikes forever; sometimes they hid it (like on the early XJs) sometimes it was right out there in the open, like on the 700 and other later XJs and most of their current crop of sportbikes. Believe me, if it weren't necessary they wouldn't have gone to the trouble.

Even if the fender is removed, a fork brace is still a good idea.

 

I like the bike. Cant wait to see more pics as the project goes on. I'm planning to raise the tank on my 750. How are you going to mount the tank? I've never done a tank lift before.

 

Sorry for the delay mate. To raise the tank I just welded an exact replica of the stock tank mount on the top tube of the frame (backbone ??)

I will get a photo and post it on.

 

I need some feedback please. I have now welded all the new mounts for seat, tank and handlebar risers. When I did it in the workshop I liked the look, when I looked at the pictures later I did not like it and felt the tank is way to steep. Please give some opinions / ideas.

I am thinking to either put it back to its original mount or halve the current height increase.

Also, will the tank actually function properly like this ??

The seat pan you may notice is back a fair way, but I am 6 ft+ and long legs, so it has to be there.

similar set-up, but tank in stock position

 

The front of the tank really needs to drop. The raised idea is cool, just needs to come down 3 or 4 inches. Make the tunnel even or a tad bit lower than the top fork clamp.

XJ 700 wheels will work. You will need the entire rear brake set up. On the fron you will only be able to run a single brake (the 700's have duals) and you have to use the rotor from the 700, but can use the caliper from the 650. You will also need to make or buy an additional spacer for the front axle. I used XJ 700 wheels on one I built awhile back. Have been too lazy to post pics.
