nice rack!

[remegio731]

, yeah it remind me always before,.. after came home from a job, first thing to do was i'll go straight directly to back door to see it. now, i did save to my screensaver..
the pix bike ived posted here is not mine,..anyway, sharing the idea of whom you guys are planning to have a set project this winter..cheers

You really had to push your seating foward to make the R6 tank work, the R6 gas tank is 2 1/2 " shorter than stock 400 tank. Im having problems getting mine to line up with the R6 subframe, the gas tank ends up 2" from the front stem. Its forching me to mod the R6 subframe and make new mounting holes to get the gas tank where it needs to go.

How does your bike handle in the turns ?, seems like you have really changed the geometery of the bike?

FZRM,
the fact the R6 tank is 2.5 inches shorter should be good news for those of us less than 6ft tall and any one considering giving his GF an FZR as the reach to the bars will be that much easier.


Does the R6 sub frame bolt up to the 400 frame ? perhaps shortening the sub frame and making new inserts for the frame mounts would prove easier.?

[Fzrmike33]

I had my 400 mounting tabs on the frame heated and bent in a little to fit the R6 subframe. The problem with making new mounting points on the R6 subframe is your dealing with hollow material, where as the stock holes in the R6 subframe are solid and beefed up.

I think the answer is to move the 400 mounting tabs foward 1 1/2 " to slide the tank foward to a acceptable spot. The R6 subframe gas tank mount area is not tweakable pretty much, so moving the 400 mount tabs foward seems like the right answer from what i see.

Mike,
Here as I have seen the mount points on the sub frame are trimmed off. new mounts are made from solid and slid into the new hollow end. Once the whole thing is set correctly the sub frame is drilled thro the tube & solid bit & pinned then welded PLUS the tube to solid edge is welded.

I have seen this done with nothing more than an angle grinder fitted with cutting disc then a scurfer wheel,hand drill gun and a welder. so there is nothing major in the way of heavy engineering just patience & time.

With your idea you need some heavy heat to re-weld the main frame tabs plus you will spoil the factory heat treatment of the frame which could cause it to warp!

[Fzrmike33]

I will check into that George, but from mocking up the bike it looks like may not work. When you shorten the subframe you get the tank foward in the process, but you also lower the rear of the tank more into the main frame, and your angle of the subframe changes because you have to keep the gas tank flat to the frame. I did slide the subframe in further up from the holes and it puts the tank where i need it from front stem, but like i said the rear of the tank drops much more into the main 400 frame.

My guess to cut subframe and make it work, you would have to change the R6 gas tank mount, and now that throws off the seat into the tank

[Fzrmike33]

I think moving the 400 tabs forward keeps everything in line with how the bike was with stock sub, it seems to me the best way to do it. I have already had the tabs welded before, so heat treat in that area is gone already, i will have to have someone look at it, i would just love to cut the R6 sub and move on.

[Fzrmike33]

Well here are some shots George or anybody im open to ideas ?

[remegio731]

mike, did you try to put the plastic sides cover on? well in that case you have to move your tank a bit forward to look it better, try to increase the height of the tank bracket on the rear portion, dont weld immediately u have to make a temporary fastener (small wire or small ropes to tie) in that way u can change it easily..sorry i woudnt have any suggestion anymore since i use only a stock 400 subframe, i did bent mine a bit higher, increased the bracket height to adopt a sagging R6 tank.



however handling is not so good on the track, coordinates with height and base length beetween 2 wheels(front and rear) someone is trying to adjust the preload on the rear suspension to gain better handling, i didnt tried, i'll used mine on the road though..thanks

[remegio731]

Geo is right you have to be dealing with lots of patience and time..you can make it anyway

[Fzrmike33]

No i have not tried to put the gas tank side covers on, you have to realize im using a 2006 R6 subframe, not stock 400 subframe, whole different problem than you had. I may have to move my tank up more, but not sure yet, have to figure best way to get tank forward first. The R6 gas tank mount is fixed on the R6 sub, cant move it.

Im thinking i would have been better off with stock subframe, then at least i could have welded up tabs where i wanted them, . I just figured using the R6 sub would make the tail, and seat and tank fit better without having to make many brackets.

[yamaha_george]

Mike,
sorry to say what at first looks easy turns out to a have a knock on effect every where else. I have had it SO often oh afive minute mod yeh right more like 5 months of head scratching / banging but it usually comes out ok.

TIME & Patience & more time is all it takes, then some smart a*se comes by and says why did you do all that all I did was blah which really would be a 10 minute job !!!!

[Fzrmike33]

You move the frame tabs foward, or you make a bracket that comes off the tank mount and it will push the tank foward. With the last option you must add fiberglass the tail cause you will be short of reaching the gas tank cause you slid it foward, so which is the easiest to do ? i say move the frame tabs foward.

yes Mike, i think thats the only solution there,,you are dealing only with 2 tabs for your subframe to move forward..
