Planning to get rear set brackets from Yoshimura for your Ninja 300?

KOOL!

Just don't get it from Yoshimura...

I ordered their Yoshimura rearset bracket kit for my Ninja 300. At the time of installation, everything went fine till the point I needed to replace my stock shift rod with the one provided with the kit.

IT DOESN'T FIT! THREADING TOO BIG! (insert joke)

Some of you know what I'm talking about. For those who ordered it and tried to install it..then found out the shiftrod doesn't fit...I got the same response as you did from Yoshimura.

"It's the correct part, it fits on our R&D bike."

"The rod had reverse threads, try putting it on the other way"

etc. etc

I won't make this a long rant about their rearset product. For some people the shift rod fit, for most people including myself, it didn't. Could be because its a new bike, but if its almost identical to the 250, there shouldnt be a problem

If it fit on correctly, the bolts don't have to be forced to spin on the rod threads or the rod arms attatched to the bike. It should be an easy twist on twist off like a bottle cap

Save up a bit and get more high quality rear sets...but if you want to give it a shot and settle on Yoshi's, go ahead.

I just wish someone did more reviews about it not working

***Refer to the 3rd page of the thread to read a positive outcome to a negative situation :D***

I know an engineer at Yosh and forwarded this thread to him. We'll see what he says! It's hard to believe that all of their parts would be wrong, but maybe you're the first to notice? Who knows. We'll see. Were you sent the correct part from Yosh?

Actually, I have the base model Ninja 300. I know for the ABS model there might be a problem though...so I've heard..

The brackets themselves fit perfectly. I'm actually very impressed with the build of it.

I have read a thread on this forum in the Ninja 300 general discussion about this problem, but I felt I wanted to start my own thread and make it aware to others they MIGHT run into the same problem with this product

The problem is the shift lever supplied with the kit doesn't fit. The threads are too wide. I can't even fit the first thread on the bolt. I'm guessing I can force it..but I don't want to strip anything. Plus, it shouldn't take so much pressure to twist into place.

No, I didn't get a shiftrod that fit. I was sent a new shift rod, but unfortunately it was the exact same (non-fitting) sized shift rod that was supplied in the kit.

I called back Yoshimura and let them know that the new one was also not fitting on my bike. The response was that it fits on their R&D bike, its the correct part number, therefore it should fit. This was after I explain my situation and even showed them the comparison pictures..same ones I posted on this thread (>_<)!!!!



Bascially, I'm stuck. I bought it from biohazard cycles, and now that I already tried to install it on my bike, I can't return it :( ! So I go to Yoshimura for help, but they haven't done much of anything...

This is my first time buying a Yoshimura product...and pretty convinced it will be my last..

Why do you mention the 250?
Was the kit you bought meant for the 300 or the 250?
Doesn't matter they are identical.

My experience with yoshi regarding the extremely fast yellowing of my CF end cap was not much better than yours it seems........Yoshi have really fallen in the customer service department seeing that they tote themselves as a top end manufacturer.

I wouldnt say that your totally screwed, a simple re-thread/tap to reduce the size of the threaded bar will suffice. If you have no tap & die kit, any of your local machine shops will be able to do this for you for a few dollars, or even a free beer. Will literally take them minutes. Even better, a basic tap & die kit is quite cheap and then you will have useful tools for things down the track. I always add to my tool collection where possible if cost is cheap.

Not sure of the size that it is supposed to be, someone else will probably chime in with that or it can be found more than likely in the service manual. An alternative too is grab a few different sized bolts and find the one that fits then you will know the size and pitch of the thread that you need it threaded to.

Another alternative........and I used this on one of my previous bikes to replace a lost shifter bar (came off whilst riding :eek:), was a simple threaded rod in the correct diameter that you require, and simply cut it to length. Most threaded rods come in 1m and 3m lengths and can be bought from any hardware store again for very little cost. Standard 4.6 grade will be more than enough for this application and can be had in a multitude of treatments......I would go with galvanised just for longevity. I had my "temporary" one on my bike initially just until I could get another OEM one.........never came about and that stayed for 3 years no probs.

Of course the all threaded rod wont look as nice as just having a bar with simply two threaded ends, but it worked and got me by for much longer than I had anticipated.

Well..the rear set kit is labeled (Ninja 250 & 300). Other than Yoshimura saying the same kit works on their R&D bike, I have seen a couple of riders on youtube that also used the Yoshi rear set kit on their 300, and not one mention about the problem. At the same time, I've found other 300 riders inconvenienced by a shift rod that doesn't fit their 300. According to Yoshimura, the 250 and 300 part numbers are the same for the shift rods

Thnx a bunch for the suggestions Jeff! I actually have thought about going to a machine shop with my stock shift rod and the one Yoshi sent me..to see if they can do something about matching the threads. If not, I'll give your later suggestion a shot.

More than the inconvenience of the shift rod not fitting, my main frustration was of the products manufacturer. I know they're very popular as far as motorcycle performance parts...but the customer service (or lack of..) was not what I expected. I felt no matter how much I explained and proved that their claimed product isn't fitting what bike they created it for, I got a slap in the face and "have a nice day".

Here's an e-mail I received from Yoshi..

Anthony,

We did have a problem a few months back where the incorrect shift rod was packaged with these kits. All inventory has been checked and corrected since then so you should get the correct one without a problem. We are located in Chino, CA so you should get this within 1-2 business days. Thanks!

Ok, I heard back from my engineer friend at Yoshimura R&D. Here's what he wrote:

“Regarding the shift rod thread, there is indeed an issue with the threads being cut incorrectly. All inventory was put on hold last week to be re-worked, and any customers with this issue should contact Yoshimura customer service at (909) 628-4722 to get a replacement part.”

It's nice that we have good guys like SPACEPOD on these forums, who help out fellow motorcyclists. My guess is that the problem was so new that the customer service rep didn't know the problem existed, and wasn't able to help out.

Thanks Spacep0d. I did give that number a call, and the rep I spoke with did in fact say that many shift rods for this kit were unfortunately incompatible with the Ninja 300.

He asked me to measure the threads of my stock shift rod so he can see if the one he has ready to ship out to me is in fact the correct one. (I really hope so...)


I'm also guessing because its a new bike there could be some issues with product fitment. But for it to be said that all part/part numbers are identical between the 250 and 300..then to have a customer find a defect in the actual part..to just not do anything about it got me really upset.

Its been about a month and a half already staring at these Yoshi rear sets sitting in the corner of my garage (>_<)

If all works well, I'll post up some pics on this thread of the outcome

They are identical. I installed the yoshi rear sets i took off my mates trashed 250. Im guessing they have multiple products that use shift rods and they got the wrong ones in the box(probs from the GSXR or CBR). Not really a big deal to get it re threaded to suit imo.

i contacted them back in march of this year and they told me that theirs fit their bike and they'll send me a new one just in case i got a bad one. i got the same exact shift rod with the same issue. i just said fuck it and made the threads fit. now i'm pretty sure my linkage ends are fucked but i might give them a shout to get an actual correct rod and see if itll work. I'm currently not using the lock nuts.

Yea, the I can get them re threaded for the proper fit. But the thing is, I paid for their product..and since it doesn't fit, I require their service. I don't feel like paying extra to drive somewhere to get someone someone to get the rod re threaded and pay for that (or buying the tools to do it myself :p). I think because of their lack of help makes me wanna push the matter to actually get them to help

Iono..I guess the magnitude of getting it rethreaded doesn't seem so big...but its the principle of the thing.

Call me stubborn, but paying for something that doesn't fit on what its supposed to is..eh..

I feel ya there mate, I ended up recoating my end cap myself and keeping the spare that they sent me, but it took a few emails to finally get them to send the spare one. No instructions or offer of advice on how to fit it, there are plenty of videos online I was told. Great after sales service they have. :rolleyes:

Spray a good amount of PB Blaster on there and let it sit for 20-30 minutes before you start trying to wrench on it. I read one of your older threads and it sounds like you cross threaded it on there. If it is cross threaded (I am pretty sure it is), then you need to wipe down the area that you sprayed PB Blaster on and get a torch and heat up the threads some and then try to back it out. Be easy with it when you are trying to back it out the rod, you could snap it off at the threads and then thats a whole other process.

crisis averted! i let the pb sit a little longer and took off the shift lever. i was able to turn it until the lever side came off, and throw on 2 spare nuts locked together to back out the transmission end. miraculously, the revised rod threaded into the linkages smoothly, and i was able to use the factory lock nuts perfectly. i thought my bike would be down, but everything came together nicely afterall :)

Awesome! PB Blaster is an actual Metal Penetrator, so sometimes it needs a little time to work. WD-40 isn't a real penetrator, more of a softener. PB Blaster is the best. I am glad you were able to save everything, could've been a much worse (expensive) situation.
