"Buzzard" may trade for WR250F in 10 days

Read the torquing specs and sequence carefully from the factory manual.  Yamaha’s are very specific and especially with a big bore if not done correctly they will leak. That can ruin the head and cyl. I use new head bolts in the process. 
 

Good advice Steve👍 

I have done a bunch of them..

I have owned 3 450 5 valvers... Son still has one if them...

And I have done many for customers...

This is just the first 250 5 valve that I have personally owned...

I am very familiar with Yamahas "torque to yield" specs.... And the need for fresh bolts to yield 👏

My Lovely Lisa helping the old man with a fresh knee replacement get the first once over power wash on the new garage mate....

Ugly ass stickers removed... Gaudy white hand guard extensions removed...

My Love and my Hero!!❤️💪 

The tires are the showroom original Dunlap's.... Bald now on the rear...

Air filter is THE ORIGINAL... intact but starting to break down...

I like this bike a lot for my start point... Not a lot of maintenance, but not a lot of use for an '06...!!

Lisa said:

"we just got this thing in time! It's more like a rescue than a trade!"

then after the cleaning we were just sitting in the shade in the garage and looking at the bike while it air dried... And Lisa all of a sudden asked me, kind of panicked:

"Does this one have a pumper carb?!?!!"

I said... "Yes, the best one actually, an FCR!"

to which she immediately replied:

"Oh! That's Good!!"

true story❤️❤️

Are you going to dyno it?

Probably not...

I sold my last dyno to a friend of mine years ago....

Sredrum Racing is a carb and throttle body taperboring specialist... 

I have an open invitation to use the dyno all I want... Same as he had open invitation to come and use it at my shop in Michigan while I owned it..

He's in Ohio ... I did make the drive a few times from Michigan to do some testing... But since moving to Tennessee 7 years ago, I have not made the much longer trek...

When we would dyno with each other we would bring extra boxes of components.... From carbs to cams to pipes to intake setups... Strap the machine to the dyno...and literally make a weekend of testing and swapping components... Not just doing jetting / tuning work...

Now it would be a 14 hour round trip for me, not including time on the dyno... and I wouldn't be able to have a baseline run unless I made the drive initially just to dyno the machine before the mods began...

I dearly miss that kind of Dyno access...

Other than that kind of access, you are stuck with things like 3 to 5 dyno runs with no tuning or parts swapping of any kind, for $150~$200.... Barely enough to warm the bike up to get a solid baseline...

Would love to dyno it to death and back again , testing everything like in the good old days... But sadly that isn't likely to happen☹️

I haven't read much good from you about your Yamaha's except in the longevity department...  I believe I have read you were not a fan of the handling several times,. 

Sure Larry... Gimme the low down...

But remember, you aren't riding a stock 230 either😁

Ok Mr Mixxer my spare 230 has stock engine only carb and suspension. The wr250 is bullet proof  will 60 year old Mixxer . Ride it faster in tight woods or hard trial then the 230 😂. Hell no you will fall down much more . Now  to fix that beast on all those early year wrs . Front fork is shit do not spend money gold valves and fix it's. On our 450s we use  xr650r forks . On wr250s  xr400 fork or later year yz fork . Rear shock revalved  with 250yz ti spring . Would not hurt to lower rear shock 3/4 in or 1 in. 280 big bore kit much cheaper the 290 kit . They have good bottom end stock up to little over 1/4 throttle mid range they suck . Big bore fixes that  top end power yes. This will not matter in your neck o woods . Not much speed in 5th gear even with 14 on front .

Oh my this is getting interesting!

I test rode 3 WR250Fs and rejected them because of rough and notchy throttle response.  I was sure it was fixable but was advised it was caused by the WR250 ECU so bought a CRF250X instead. No problems to date.

On suspension it all depends on your terrain and how you ride. I bought a CRF250X is AZ that had R forks on it courtesy of a PO, while it was OK in AZ it was terrible on WA PNW trails, which resulted in a lot fork/shock revalving.
I've found that my suspension issues and fixes seem to be similar to Baja's, yet WA PNW and Baja seem so different.  YMMV depending on where you ride but be forewarned it can be a long journey.

Stock WR250-450’s need some mods like every other bike made. But no Bultaco XR650 forks or others. 
 

Very simple mods. Derestrict it, cut the grey wire at the ECU. Change the defective base valves to Racetech gold valve so you have standard shim stack forks like a YZ. Send the carb to Zipty racing to drill the needle jet and make it work. 
 

From there the real fun starts with porting, big bores, cams, pipes, tapper bored carb, Dynatek ECU and on.

Like when he took his Yamaha and was crying. Saying too many rocks 😂 what rocks when you have bultaco forks . 👋 Sorry bro rode your yam and bbr beats you to death . Bad money over bad money gold valves .

Poor old mixxer....☹️☹️

We have Larry and Chuck crushing my spirit and killing my ,I have a bike I have always wanted joy...

Terrible suspension that can't be fixed short of replacement... Uncontrollable engine... What a bummer....

Only Snakemaster Steve giving a ray of light and hope.... This must be the end times!   That would be in alignment with my karma for sure..

"Okay, we have confirmation that mixxer got the WR he has wanted forever, Release The 4 Horsemen!!"

From what Steve has said , I have:

1) found the gold valves for the 06 and they only fit that year... Earlier take one set, later take another set..

2) I didn't see a drilled emulsion tube offered at Zip-Ty , but did find it at thumper racing... I did find where a part number was supplied for the WR250 tube that came pre- drilled ,and it matches the part number for OEM on my 06... Will have to pull apart to verify...

3) grey wire will for sure be cut 

My older son, Samuel, has an 04 5 valve YZ450F that he bought from a dude who set it up for woods riding. He had sent the suspension to Pro-Action for the full "triple valve/ re spring" work.... Took forever to pull the ugly ass Pro-Action decals off the forks... That bike has some of the best woods suspension of all time.. roots and square edge rocks feel like cigarette butts in the trail..

I don't know the comparison of YZ to WR suspension at all though...

When I built my CRF270R years ago, the 270 kit sucked to install (cases needed relieved... A lot!) The 290 kit I bought for the WR will almost install itself...

I had Sredrum taper bore the carb to 40mm...  Was not too big for the bike at all... Worked perfectly... I'm debating having the WR carb punched out to 40 from 37...on the fence at the moment...
