Here's a couple pics of my headstay.

Post by **AlisoBob** » November 21st, 2007, 3:28 pm

Now that folks are using my info to build their own, I began to ask myself.. "Is there anything you would do different?"

See the photo above... That's as far "clockwise" as you can rotate the motor with the stock cradle. The bolt below the clutch cover barely misses the frame, and the water pump up front does the same with the cradle.

If I had it to do over again, I would have modified it more, to turn the motor a few degrees . I have plenty of room for the radiator cross over hose. I would trade some of that clearance for a easier time routing the coolant hoses coming out of the head, and to raise the rear of my pipe up a little.

Just a few more degeres would make allot of difference...

....next time!

Too many edges on that, will eat right through that clutch cable in time. Would be better to put a phenalic rub strip on the metal or wrap the cable in chaff tape in that area.

Any updated pics, Bob? Looks like it is really coming together well. What did you end up doing to get the tank to fit? Heat and smoosh ?

The tank issue still exists.

its hard to tell with the photo, but does the bolt almost hit the cast or forged part of the frame/weld or the tube? if its the cast or forged, i have an idea on how to get that to clear nicely without sacrificing the strength of the assembly. the water pump issue seems fairly simple, once you get the other done.

ive been trying to find a die to bend some tube up before i cut my frame, but its hard to find a square tube die that doesn't have the rib to fold the inside part of the tube, and i can't use a mandrel with my bender. i could make a die up myself, but i don't want to put the money into that and not get the results i want. i may throw it a piece into my round die and see what kinda results i get. ive heard of one person getting the results i want with square steel in a round die.

reading the problems with the fuel tank is making me want to just weld up like a 3.5 gallon tank out of stainless for mine going up and out .Does anyone know where I can get a fuel neck that bolts on?

Black pipe - thought it was a CR250R for a moment.

I'll fall on my sword again - it looked just like mine but probably cost half.

So I'm thinking.... " If I dont stop staring, and get to building.... this isnt ever going to get done in time for Thursdays ride with Brit....."

So I'm looking at the headstay issue, and think about my original plan to move the frame block over, and fab straight plates... Bad idea ( time wise) because its double the work... two tasks instead of one.

What to do....what to do...

I know, look in the junk bucket....

I think these are Gen 1 CR125 head stay plates ( anyone know?) PERFECT angle!!

These are going to only take slight reworking!! If the bike buzz's badly, I may still lop off the block and go with my original plan.. but for now... I'm taking the easy route...

Ported&Polished · Post by **Ported&Polished** » December 6th, 2007, 9:36 pm

That looks just like how I thought you should do it. Cept maybe a cross member in the middle of the two plates.

Post by **AlisoBob** » December 7th, 2007, 12:45 pm

Since the plates are installed backwards, I cut off the tab and flipped it. Once TIG'ed together... WHAMO! Done.

That little ,factory, pilot hole lines up EXACTLY with the foreword mount hole... You just have to open it up to 10mm. Shithouse luck or what!

Friggin' SWEET!

Thats as good as the stocker, nice job

Post by **AlisoBob** » December 7th, 2007, 12:54 pm

Thats what I want... OEM Baby!

That $20 of yours will come in handy to finish the bike!
