First of all thanks for all your patience and here's wishing you all a Happy and Healthy Thanksgiving 2018 !!!

I'll be sending out emails and or PM's to those who had expressed interest and I've set aside a quantity to cover the first people interested - I should have those messages out by Thanksgiving eve


XT225 / TTR225 to TW200 Output Shaft Extensions now ready for mailing to the USA & Canada

I will guaranty these for fit and function and even performance under their intended use in adapting Yamaha XT225 and TTR225 motors for use in the Yamaha TW200 chassis - I'll replace the unit if it fails while the original purchaser owns the unit

Package includes the output shaft extension, (6) 8-32 x 1/4" allen head set screws and a sealed outboard bearing to replace the OEM bearing that was oiled by engine oil in the original configuration (I'm still waiting for the allen 8-32 set screws from Grainger while all other ebay sellers ship the same day Grainger still takes 2 weeks to do the simplest of tasks - All items should be ready to start mailing Monday November 26th)

You may need a drop or two of Permatex ThreadLock Blue for the allen head set screws - these only need to be snugged not massively torquedthey entire shaft is held captive by design so the retainer screws are a redundant feature

Total Price Delivered is $279 to USA & $299 to Canada
USA can pay via paypal friends & family option or by mailing US Postal money orders or Cash

Total Price Delivered is $279 USA & $299 Canada

Any Canadian orders already received I will honor my quoted shipping price and there are a few other Canadian forum members who I did send an initial special offer to and I will also honor those quoted prices through midnight November 30th 2018

Thanks and sorry for any confusion the revised Canada postage rates are basically starting December 1st 2018

Fred, do you recall how this was manufactured? Fully machined, investment cast etc.. ? (don't say printed lol). It looks rough cut in areas (the ends).

Has one successfully been used for a good long period of time and what was the lube method actually used if you know? I'd consider a sealed permanently lubed bearing if one was available the correct size.

I looked for the thread but can't seem to locate it. But I am interested if it's a proven part as I have a pretty new 6 speed engine. My memory fails me but I thought Brian? May have run one?

I'll see if I can find the OP it was a gent out of Gold Beach OR and yes they were testing on one or two of their TW's but like me they don't rides tons of miles like many on our forum do. They wanted more people to test

The digital camera greatly enhances grain structure and scraches etc I find this with guns all the time the can will show a flaw you can't see or feel with the unaided eye.In hand these look and feel very high quality

it is CNC cut from the same steel as an OEM output shaft and it uses the OEM outboard bearing they just packed it with grease it already has a seal . One of my TW's runs a ScottOiler so I was going to try that.

Greased trailer wheel bearing run multi thousands of miles and with modern grease technology it can easily run longer than a TW can live

The OP had a few hundred miles with no problems as I recall

The OP had guaranteed them to me abd wanted my opinion but plans never materialized on my engine projects although I'd still like to build a TW250 Bananachunks style

I'd really like to upgrade my motor eventually. It would be nice to know this would be an option if and when I get to a new motor.

The most concerning design issue would be the set screws, but I imagine red loctite would do the trick. I doubt it would get hot enough to break it down.

the designer determined the set screws were unnecessary and will not be used in any further designs the shaft fits with precise tolerances and is fully captured on both ends regardless. that being said he never had any come loose and a little loctite would end any concerns but even if they fell out it would not make any difference

It's an ingenious design IMO saves a lot of hassle splitting cases and having output shafts machined plus the motor can still be installed in XT's or TW's

I had planned to find a no mile XT225 motor and I could install it in my TW that very day and be up and riding as opposed to the learning curve of splitting cases and just my luck something in my new output shaft would be slightly off kilter (as has happened to a few I'm aware of) and I'd have to pull the motor and split the cases again

WIth this you can upgrade to a fresh motor with ease and the motor you pull can still be sold to an XT or TW owner

I know when I bought them the OP had a waiting list for more of them it was all I could do t purchase 2 instead of just one and he gave me a full guaranty of quality and offered to buy them back if I didn't use them but I figured I would offer them here rather than bother him as I am more than happy with the deal

I'd definitely be interested. My XT225 cylinder is getting re-sleeved for a 250 piston at L.A. Sleeve as we speak. I got a fresh TW output shaft but havent found anyone able to do the machining, so this sounds like a great way to get her up and running until i do, if nothing else.

Hey Bootz,

Take a look at the picture below. The top one is a stock TW200 output shaft. The middle one is a modified TW200 output shaft. The bottom one is a stock XT/TTR225 output shaft.

The modifications to the stock TW200 shaft involve grinding an additional circlip groove and the fabrication of the spacer/washer shown on the center image below.

If this is a job that you would like to try and tackle, I could send you the above XT/TTR225 shaft and the modified TW200 shaft that you could take the actual measurements from.

Let me know if you are interested in doing this,

Thanks,

Brian

I remember seeing that old thread somewhere too. I'd love two of these as well, but if not, i'd take someone that could modify one.

I have amassed an xt225 and a ttr225, no idea on the running condition, haven't got that far yet. Figured i'd need to rebuild them anyway.

I could cut that Grove no prob. Assuming the hardining dint get to hard or deep. Not that I still couldn't, just a little more PTA

If you could send a spacer.....or the dimensions. If the spacer is what I think it is, it should be no biggie


With that "adaptor". I could build most of it,. But the splines on the inside....hmmm. Not sure we even have a tool to do that. Man I wish I could talk my boss onto a edm machine...then we would be in the adaptor business

Has anybody actually checked the hardness of the XT or TW OEM shafts? I won't have access to a tester for a week or two

My machinist is A) busy as hell and 2) celebrating summer and his 30th anniversary so it will be next week before I can face to face meet re the projects of the extensions and cutting the new grooves and making the spacer washer. I'm hoping we can find an off the shelf washer with at least the ID close (or some DOM tube etc) so they would be easier to make. I've always found July and especially August to be dead months for getting business done but I'll be working on it

Hi mate
How much are these counter shaft $ and do you post to Australia
Cheers Eddie
the originals were $300 each but I still don't have the final numbers from my machinist but rest assured I'll post here when I do I think we will know in a few weeks

If you factor in the time and labor to remove output shafts from two motors, modify and raplace the output shaft I think this is still a better way to go at least for me and the XT motor can always be used in an XT or TTR again if desired
