Ref mudguard - just finished mine

That’s starting to look very good Phil 👍

Having just gone through all 5 pages I love this build.  As someone just starting out on their Cr750 journey it's brilliant to be able to draw on all the photos, research, pointers and tips from you lot (as well as drool over the bikes coming together).  I'm a million miles away from finishing mine but really great to see how other people are going about their builds.

Keith - very envious of your work space, it looks spotless.  I've just had a damn good sort out of my garage here (mainly so I can hunt down parts for my build) but most of the time it looks like a bomb's gone off!

Have these on eBay for a CR genuine NOS if anyone is interested

Mudguards look pretty good Phil
What are they made up from ?

[philward]

Standard mudguard - used the brace but lowered by 13 mm to accomodate 18 inch wheel (otherwise the mudguard has a large gap between tyre and mudguard) . Then cut the stays to suit. Welded back of U section where they overlap the brace (near the fork lowers) then blind drilled and tapped M6 to be able to screw through the brace into the stay. Used m6 allen button screws with nylon washers between guard and stay with half nuts to give plenty of clearence to the tyre at the other end of the stay. The blade is from Tony Huck at Maitland Racing - at £25. Its very tight with wheel and tyre being smaller and wider. You have to fit the brace behind the offside disc brake arm swivel (where as the brace goes on the outside of the nearside disc arm swivel (as standard bike). You have to be quite creative with the brace mounting sequence as the bolts at the rear can't come out as they foul the ally rim (due to the 18 inch rim being lower). I cut the rear nearside brace hole in a U (as apposed to a hole) so it can 'slot' over the bolt.
This setup creates the next problem - the fact that the brace sits behind the offside brake arm swivel means the brake set up will need re-shimming to ensure everything runs parallel - thats the next job.
So overal cost me £25!
Hope that all makes sense.

Just realised your running Gold Wing forks/brakes - so maybe you could use the Gold Wing mudguard brace with the stays from a SOHC model

Thanks Phil, food for thought, bike looks good mate, when do you anticipate completion ?

[philward]

Hopefully next summer - main thing to decide on is whether to go for the narrower alternator or keep with the standard and cut fairing - I would lose the electric start if I go for the narrower alternator as the Electrex World product - http://www.electrexworld.co.uk/acatalog/RPK-1750-Honda-CB750-SOHC-Alternator-System.html - ditches the starter gears. Plus adds about £750 to the build cost (alternator plus cover).
Ultimately I'm looking for the same look as your posts original CR picture with not quite the expensive detail!

The devils in the detail Phil
I don't like to spend lots of money on the paintwork but that's what everyone sees on the finished job

Question
Do you know the entire length of the original CR mudguards  ? and what length is yours. ? what diameter wheels are you using ?
It looks good and as near as it can be.
My forks are GL1000 and ill need some mods as well as a fork brace.

I can see that others may have had problems posting pictures.

I am , it used to be ok but now no go
I usually upload pictures from my phone to my Yahoo, downsize them in photoshop to around 450kb
and use the site attachments and other options bar, browse, load the picture and post.... But no go.
thoughts ?

I have just added jpeg to the list of allowed attachments - maybe Yahoo or the resizer has switched from jpg

I've also increased the allowance for each attachment to 2M and the total per post to 6M

That’s better, didn’t even have to resize it, our pug doing her ET impersonation.

Not sure on original mudguard length but mines 780mm. Ref paint, I agree - mine will be right as per that Aussie rep (your original picture) which is what I've also based mine on. I have a guy who is a car sprayer who has done all my bikes - charged me £70 labour for my standard k2 tank/side panels (I do basic prep) - its mint. Its not what you know, its who you know!!!!!

Still cant post a picture, Ill try another route ?

No,  again My system says Server error
