Well it looks like I got a bad fourth gear so I am going to be splitting the cases in my 426. My dad used to be a mechanic for Honda, (long ago) and helped rebuild the trans in my shifter kart and he routinely rebuilds his XR so I think it is within our ability. What I wanted to know is if there is anything I need to be aware of. I have the manual which I hear is pretty detailed, but are there little tricks that those of you who have done this can tell me. Is there any special tools that I need, do the cases split easily, etc....?

Also how much should I expect to spend on parts? Thanks in advance for all the help.

Sounds like your Dad should be able to handle it. Try to substitute for the pulling/pushing tools called for in opening and closing the cases as well as you can.

I've done my 400 twice, follow the manual and you'll be fine.

It's real easy the transmission will only fit one way.

Do I need any special tools to remove the fly wheel, clutch basket, etc...? Anyone know how much the shift forks, gears, gaskets and rings are going to run me? Thanks for all the advice

I am curious

Did you read any of the posts in the link I set up for you?

If you did you would had seen what it costs and what would need to be repaired. If you did you would had called the shop to ask just what a new 4th and 5th would cost along with 3 shift forks. Your roughly talking about $40 - $45 bucks per piece "On a Average".

Your dad is a mechanic, you have replaced and or worked on shifter cart gear box's

Sorry but something tells me in your questions that your either very very young or ? :cry: :cry: I don't know this just doesn't seem right close to call Bull

Just asking questions, didn't know there was a problem with that. Did I read the posts you found for me, yes some of them, but after a certain amount of time they expired and I have to work for a living so I wasn't able to spend a lot of time searching. Instead I figured I would start another post while I was at work in hope that all the answers would come to me.

Did I call the local shop, yes one of them but the other was closed, so once again I figured I might be able to get some helpful info while I was busy working, like what everyone is paying for the parts, and or, where the good deals are.

You see I am relatively young (I have graduated college and have a great career as an account executive for a publicly owned corporation, if that gives you a rough idea of how old I am) but I am old enough to know that it pays to do as much research as possible before you tear into a big project.

Now like I said before I have rebuilt the trans in my shifter kart with the aid of my father, it was a few years ago and there were a lot of parts (and that's a 2-stroke) so I want to know what I am getting into before I tear into this thing. From what I've heard on this post and what I read in the other post it seems very doable.

So once again thank you for the help in the other post. Now if you have any more answers to my questions feel free to contribute, but if you’re going to try and belittle me by guessing how old I am or post philosophical tid bits on everyone of my posts take a hike :cry:

Oh yeah here's a link to the bike I just bought

I can't remember the exact name but you need a tool to hold on to the clutch basket. So you can take the nut off. I just used a strap wrench and a impact gun. You also need a flywheen nut remover.

Thanks for the heads up! We are putting my dads motor back together tomorrow and then we're going to Cal City for Thanksgiving (luckily my friend can't go so I'll borrow his bike), so I probably won't tear it down until next week. I think I can get clutch basket using the same method you used, but I will have to buy the flywheel tool. DO you know where I can find that tool?

I don't think you need a basket holder if you remove the pressure plate and just push down on the clutch plates with your fingers and leave it in gear :cry: and get a flywheel puller there is one screw back there so you have to remove the flywheel and don't need a case splitter it comes right apart :cry:

Belittling No, Asking questions on if you are following the instruction we give yes. Seems the answers are given and yet I would assume if one has "RESEARCHED" then the new questions would relate to those specif c to the already detailed info int he threads. As a Newbie, I would suggest you do the "RESEARCH" on your own then ask questions, Most of us will answer questions, but as you can see, it gets repetitive and over the last few weeks months these threads on this very same issue are abundant.

Now for the sake of repeating ourselves, we point in general directions. Now you can either 1: Take the advice for what its worth or 2: Choose to not take the advise. By choosing 2 you will find less and less help. :cry:

BTW If in fact that is the link to your bike, then I would say you need a chevy mechanic not a Yamaha :cry: Not sure is that your shifter Kart :cry:

I[COLOR=Blue]Just a side note, I am not getting on ya, if I was you would know it. Questions are great we encourage it, being teachable is also a very good trait. A few things I wish to point out is simple
1: You have stated, Experience with working on Bikes or Karts (Same Thing), However your questions dont seem to point in that direction

2: You ask about tools and such: yet you have indicated you have or are in the process of putting your dads XR back together :cry:

3: You have stated your dad is an experienced Honda Mechanic: Yet your questions led to a point of either you doubt your dad or as With My son (He is 25 Never believes a word I say) Thus the How old are you question

4: When pointed to and specifically laid out a Link to posts, you did not read them or at least you read some of them. This leds to think that 1: your not inclined to research on your own 2: Your unwilling to accept a answer 3: your unwilling to research 4: all the above[/COLOR]

Now this is of course a simple observation and a Humble (Yet Arrogant) Opinion on my part. I will leave it be

Like I said chief, just doing a little research, if my questions are repetitive skip the post. Unfortunately I have a job, a job that requires all my attention, so I didn't have time to read every post you found. Seems to me like the other people that have read my post didn't have a problem answering my question with out trying to figure out how old I am, or how much experience I have. Once again I was busy and I figured if a few of the guys that read the post had some experience on the subject they might lend me some advice so that I don't have to track down the answers

If you yourself have worked on different motors than you would know that different brands of motors have unique qualities, which is why I asked if I needed a unique tool that I may not have needed on my kart or my dad's XR. Granted my dad did tell me that I would not need a special tool to plit the case, however I thought I would double check because I don't want to be half way through the project and not have the right tools to finish the job

Do I care if you think I am kid or if my dad was indeed a motorcycle mechanic? Not in the least!

I'm over it, I've had good luck on HotBoats.com when I've had questions about my boat, and when I ran into troubles with my bike someone suggested I come over here. I never had intentions of getting in a dot.com battle, so I appologize if I have waisted anyones time with this crap. Thank you to everyone that offered up some helpful advice, I have answered all my questions and I will split the cases on Saturday.
