Just need some verification on a subframe....

[Slowprocess]

Just need to verify that this.............







.......will fit on this............before I start to break it down.

From the pic it doesn't look like it. I have a 07 and it doesn't have the support bars that come down to the bottom of the frame

Yeah its an aftermarket 6 point subframe that's mounted on an 04 frame. I'm mainly trying to figure out if the older subframes will work on the newer R. I'm going to have the tabs welded onto the frame for the bottom mounts if i know for sure it will work. I'm just not 100% on what brand subframe this one is, so I guess that's the main question. I can do some chopping on some plastic if I have to and I'm not running an airbox so that won't be an issue.

The best way to know is pull the rear fenders and look at it it's hard to say looking at pics

Part numbers are different, but am thinking it wil still work. Shoot Daddio on here a PM he could tell you without a doubt either way

The newer style 6pts are different from the older models. You can use older model stock subframes, but the 6pts are different. I don't think its going to work. When I bought my JB 6pt, he asked very specifically if it was for an efi model. Good looking bike by the way!

The 4 mounts on all YFZ & YFZR subframes will align just fine. The lower 2 on a 6 point is where things get a little different. JB's YFZR 6-pt (BBC & Elioff317 can clarify) bolt to the back foot peg bolts. JB's & LSR's 6-pt for the YFZ need tab to be welded on. (as stated).

I think with some minor modifcations you could get it to fit. Welding to cast aluminum for the bottom 2 points might pose a strength issue. If the bottom two "bars" won't properly hit the frame based length/width/geometry, you could always cut the bottom two points off & weld in new bungs. My concern is the strength of the bottom 2 tabs you have to weld on.

It takes 45 minutes to pull off some stuff to see if it fits. You could do a mock up in an evening to see if it all works. Leave the exhaust on the bike as the lower bars would be of a concern, depending on the bend. Take some measurements. You could always bend the subframe if need be.

I think it can be done.

Thanks for the compliment! It's a work in progress for sure!

Ah....I was wondering where they bolted up at on the Rs. Ok, so far so good. I've got it mounted and everything is looking like it might work. I'm curious as you are on the durability of the tabs I'm going to have to mount on the frame, but I guess we'll see when I get them on. Other than those I don't see where there is going to be any more concern. The gytr seems to fit just fine. Going to try to get the tabs mounted up soon.

Alright....been thinking this over and have a new thought that might work better than welding tabs. What if I heated up the straight bar and bent it a little, cut it, and have tabs welded onto it in the same location as the walsh subframe braces. It appears they use the two fender bracket bolts. I really think this would be the easiest and safest way to secure the brace. Thoughts?

[bbcmudtruck]

That would be the way I would gow welding on the aluminum frame would be a good idea. I can snap a pic of my lower mount on my jb if that would help?

That would be awesome! I'd like to see what it looks like to compare it to the walsh brace to see which would be easiest.

[bbcmudtruck]

No problem man. I'll shoot some pics tomorrow. In the mean time, I snapped a photo of the rear of my bike for my before/after photos. Its posted in the general lounge section. you might be able to see something there thats beneficial? Regardless, send me a pm to remind me and I'll snap some for ya.

[Slowprocess]

Here's a picture just to show how close the bar is to the fender bracket mounts. Shouldn't be difficult at all to make this work.

[bbcmudtruck]

Well thats alot closer to working than I thought would be. Here are some pics of my lower mounts. Hope this helps.

[Slowprocess]

Man I really appreciate the pictures! It looks like I can go right there with mine with no problems whatsoever. Quick question for you. I looked where you ends are on my frame and I didn't see any oem bolts or anything in those locations. Does your subframe attach to the frame with bolts or does it prop against the frame to support it? Thanks again man!

[Slowprocess]

Bump.....still curious how the jb connects to the frame at the bottom. Couldn't exactly tell from the pics. Thanks again man!

[bbcmudtruck]

The JB bolts to the frame on the lower ends. However if you'll look closely where the subframe meets the lower frame, it sort of squares off and sits up against the frame flush. It helps distibute the load I guess? If you need some better pics just let me know and I'll help ya out.

I see exactly what you're saying. I think I've made my mind up that I'm going to have the subframe go to the fender bracket mounts like the walsh braces do. Seems to be a really easy way for me to go. I ran into a few other little problems along the way. The FCI is going to need tabs welded on to work. I had to do some cutting on my rear electronics cover and I had to shave a few areas on the rear fenders where it would sit flush on the subframe.....I've also found that my stock R grab bar doesn't fit on this frame. It bottoms out of the frame before the bolt holes line up. I guess the grab bars are different on the R and the standard yfz? Looks like I'll be purchasing a grab bar for a standard yfz now. Still so far not alot of trouble to get this thing to work. I'll post up pics when I decide where I'm going to mount the bottom bars. Thanks again for all of the help guys!!!

I didn't have an issue with grab bars. I run the Houser "lowered" grab bar & had it bolted to a stock YFZR subframe, YFZ, and an LSR subframe for the YFZR. I never had one issue. hmm..
