Since you just finished a resto, I'd ride the snot out of the steely..then convert. You'll have a better appreciation that way IMO.

Is triangulation needed on the headstay?

ShanMan · Post by **ShanMan** » December 2nd, 2008, 12:44 pm

yes. You can only provide a rigid hold of the head in the vertical plane of you have a three bolt pattern. Triangulation is the key to stiffness and strength. There is also considerable stiffness offered transversely (left to right as you sit on the bike) with the additional mass and clamping force that a triangulated brace gives you. if you go with a simple link (one bolt to another bolt) it will allow far too much movement through vibration and the link will ultimately fail....plus, the bike will shake like nobody's business!

I am building a o3 cr250 with a 98 cr500 motor. Interested in the two sided headstay. This is a pretty old post. Let me know.

Hi shannon. I sent an email back last week looking for mounts. I'm trying to figure out the PM deal, for some reason I can't just click on your name.

Just click the PM box......

Sent ShanMan a PM yesterday looking forward to getting started

Post by **AlisoBob** » July 17th, 2009, 2:13 pm

I believe Shanman is out of the hardware business....... But his machinist has the files.

Maybe Shan can put you in touch with him???

slowwrx · Post by **slowwrx** » July 17th, 2009, 2:25 pm

That would be great

ShanMan · Post by **ShanMan** » July 31st, 2009, 10:17 am

I have spoken to WRX...but to the rest: I have five gen one kits left which I don't want to split up, two sets of covers one of each script style, and five ignition covers beyond that. My machinist has several sets of engine mounts, gen one and gen three head stays and probably some other stuff like coil mounts, etc.

He can be reached by e-mail at: rob@evpweb.com The name of his machine shop is East Valley Precision and they are located in Apache Junction, AZ.

He will need to get the price list and some application info from me, but he is the keeper of the hardware. Be forwarned: I never, ever marked up his prices to me...so you can expect the prices of the parts to be the same or even a little more from him....he won't be selling parts and shipping them at a loss.

If any of you want/or need the stuff I listed above, let me know.

Peace!

if anyone is still using these front engine mounts or ones like them. I have found a Honda Part number for the 10x160mm bolt if you would like to stay with stock metric stuff.
90101-HP1-000 10x162 from a 2005 TRX 450R
note: received a message from Rob yesterday and he still has headstays and motor mounts to sell.

Hillbilly500 · Post by **Hillbilly500** » March 1st, 2010, 1:09 pm

yea, talked to him via email, he has headstays in stock for gen 1 and the mounts also.. What are the differences for the head stay for the gen3 vs 1??

I am sure it is in here somewhere and will look. but if you know post up.. thanks

Post by **AlisoBob** » March 1st, 2010, 1:46 pm

I hope he is leaving the cylinder head side of the Head-Stay undrilled.

The plan was to offer these undrilled, so you would install the engine and bolt one side on, back drill through the head lug, then bolt the second Head-Stay on and then drill forwards through everything for perfect alignment.

This would counter any small deviations, from frame to frame.

Its a different piece... The ones Shan offered up for CRackers Gen 3 fit perfect. Shan should have the measurements stored somewhere...

Again, these should be offered with the head side undrilled.

Both the Gen 1 and Gen 3 conversions reuse the OEM lower mounting tabs, so the motor position should be repeatable, but its not.

Hillbilly500 · Post by **Hillbilly500** » March 1st, 2010, 2:11 pm

cool, thanks for the heads up, the pic he showed had them drilled on both ends and are a gen 1..

here is a pic of mounts and headstay, he want $150 for the stay and $100 for the mounts

This stuff was never meant to be free....

I'd say having quality hardware for $250 is cheap.

I ordered the front mounts from shanmans guy. I'm happy with them. I'm lookin for someone that does headstay now.

I always cut the headstay block off the frame use 12mm or 1/2 flat plate for a double sided mount then weld the block back on after lining up the carb airboot & sprockets.. .. That headstay has a lot of weight pushing on it at full noise especially in motard with nearly zero wheelspin.. No flex in the headstay means no flex in the cradle & no cracks at the Y.. But I've only been welding & fabricating with aluminuim for a living for 15 years.. So maybe I'm wrong..
