thanks bob for your words, you and mike inspired me, ive always like the cr 500, raced them for many years. at the weekend i will take some close up. large pics, ive tried to build a bike that honda would, all brackets, and fittings are as i think they should be, neatness, and durability. ive made an alloy tank, trick one off rads,AlisoBob wrote:

I am not sure if anyone has made a headstay like that before but from what I have seen that appears to be the best design. Not sure what it would take to make it but that appears to be the strongest setup.
what it would take is to make up a mount, weld it in the same area as a 250 headstay block, as the 450 doesn't have one, and then make the plates that fit the head mount and the headstay block...i like the design but personally i have no problem with the way all of us have done it up to this point...What do you plan on doing with your existing 450 head mount holes under the frame spars? they're going to useless chunks of metal plate and will look goofy not serving any purpose...i have an awesome headstay mount that goes somehwat horizontally across the head mount and works like a charm on my 02 450...i would like to see some picturs of that bike with the tank on to see how much clearance you have...i'm sure it's plenty but i am curious...No offence of course but as far as the best 450 headstay design goes...how can you get more solid then this? this is Ben's 450 headstay...looks awesome. and i seriously doubt this design will allow for more vibration then the rear mount would...But you are the first i've seen to do it this way, and it looks amazing...congrats man!
And as far as the Head gasket spouts...did you use soft aluminum tubing similar to the thickness of a regular radiator spout? is there any problem welding softer tubing, like that of a rad spout, onto the head?

ref my tank clearance, it fits a treat, no fouling of the plug cap. all the fuel loss is. 1/8 of a litre. ref head mounting bracket, we all do it our own way. ive done it my way, and the head is supported from both sides, with a billet mount, then welded mounts the the main shock mount spar. that all crf.s have. i have made a lot of cylinder head spigots, mine drop in, then welded.
my original head stay mounts have been used to mount a bracket up on the left for adjustable cdi. right side, runs another gadget. all are hidden on the inside of frame.
Could you please post a close-up picture of your headstay block? it looks like you don't have a triangular setup but rather one bolt per side? I would be nice to see an up close pic to see what you really did...
but is there any problem with welding such a soft material to the cylinder head?i have made a lot of cylinder head spigots, mine drop in, then welded.
take your cylinder head to a specialist welder, thats if u dont weld youself. i removed the old stubbs, and made new ones, and flared the ends, then dropped in slightly to the cylinder head and welded them up.Balaclava wrote:Could you please post a close-up picture of your headstay block? it looks like you don't have a triangular setup but rather one bolt per side?

ref my cylinder head stay setup. i machined a billet alloy lump, then made 2 brackets, that are welded to the main spar. i didnt want to spar it off where the original crf mounts were. i have a genuine hrc frame that rwj used in gp,s and never had any frame vibrations, or cracks,
most of us tend to do it our own way, ideas help, just go with what you think is the best.
