CR 750 for road use build
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.
