Clip On Bars Install

I am looking to do the same thing (install clip on bars) on an XJ750 Seca and noticed that there isn't much space at the top of the fork, so it would have to go below the triple tree clamp. Reading through the maintenance documents it seems that the forks need to be depressurized for the clip on bars to go below the triple tree. Can anyone confirm if this is correct?

similar to the way it is done on this video

 

In that video, two things I noticed, one, he has the clip-on bars mounted quite low. For street riding (and me) that would be too low for everyday comfort (judgement call)
Two, he also has the forks slid upwards relative to the triple clamps. As an option I would mount the clip-ons above the top triple clamps. The XJ bikes have a lot of rake to begin
with, in the 30 degree range so I think it would work fine.

@50gary thanks for the tips. I think they are way too low myself, for comfort. I've attached an image of my set up; this might help clear up my question. I'm not sure if the "air-pressure fitting" is movable or if I can disassemble to get the clamps past it.

 

I would remove the air fittings, probably just loctite plugs in the holes. the slide the forks upward in the triple clamps and that's it. The SJ has a ton of rake in it, so lowering the triples will take some of that out. The steering input will be a little more sporting, slightly quicker than stock. I have a set of those exact same clip-ons for a different bike though.

Hi, Manny and 50gary. I don't want to steal the topic but i'm exactly in the same status. I have a xj900 seca (1983) with anti dive and pressurised forks, that is something new for me though I only worked with Ducatis and a lot of suzuki gs older bikes.
I am in to the same project as Manny, clip on but stumbled with the problem
1. Clip on will be far too low after the triple clamp, airperssure collar and then clip on also after that the lamp bracket. I noticed that the air pressure collar has a pin that goes on the triple clamp.
2. How do you fill the forks with the air pressure when using loctite, wouldn't the forks bottom way to far without air?

Maximum air pressure: 118 kPa (1.2 kg/cm2, 17.1 psi) Do not exceed this amount.
Since the right and left front forks are connected by one air hose, there is only one valve where the air pressure is measured and adjusted.
Front fork:
1. Elevate the front wheel by placing the motorcycle on the centerstand.
NOTE: When checking and adjusting the air pressure, there should be no weight on the front end of the motorcycle.
2. Remove the valve cap from left fork.
3. Using the air check gauge, check and adjust the air pressure.
If the air pressure is increased, the suspension becomes stiffer and if decreased, it becomes softer.

Still I haven't dismantle the forks, triple clamp etc.. due to not having my clip on delivered.
I really want to know how Manny solved it, cause I dont really want to use my time to laborate and risk a loctite glue that opens up and poor all the oil during the ride, better to maybe purchase the xj´s non anti dive forks.
What do I know!
If there is a solution, please share it!

 

If you use progressive springs no airpressure is needed. You can regulate the airvolume and compression with the amount of oil inside the tubes.

 

Thanks for the rapid reply.
I Am a noob in Xj900 progressive springs,but do I need any spring spacers and do I have to trial and error with the oil amount? Whats the ratio of 118Kpa redraw equal to fork oil amount.
As I described, I don't have the knowledge or the experience of these kind of forks, sorry.

 

It depends what your ridingstyle is but since you are from Sweden I presume (..) that it won't be that fast or hard with braking and cornering. Correct me if I'm wrong!!
Been to Sweden and Stockholm for the last 25 years or so and even been member of Hüddinge motorcycleclub for years.. Klubben met drag
With the springs you can use the amount of oil as mentioned in the manufacture's info to start with.

My italian/greek parents origin has giving me an excellent temperament, and it deflects my southern europe temperament on the streets....not so fast driving but a lot of cursing and using my motorcycle horn which is worn to maximum. I've heard about Huddinge MCK but haven't been there.
Thanks for the tips for the fork, but it seems I am going to be a coward and purchase a Riser Clip-on Set with 7/8" Bar that Polock recommended.
Thank you all!
