Im the proud new owner of a 1973 cb750 that Ive been strugglin with a bit to get running. The bikes a dime, only it was sitting in someones garage for 12 years. Ive spent a couple months now getting the bike to where Im happy with it mechanically, taking it apart bit by bit, cleaning the carbs, adding new floats, valves,needles, fuel lines, filters, plugs, battery fresh oil the list goes on. I got it running but it seemed like the gas flow was restricted and took a while to settle into a nice idle each time I fired it up. So I figured Id check out the valve....found rust in the screen...FUUUCK!
sO i drained the tank, its off now and Im waiting for my bucket of rusteco to clean up the inside of the tank. Its a biodegradable de-rusting agent theyve been using in the marine industry and it seems to work. The paint is a MINT original olive colour so I dont want any harsh chemicals coming near my tank.
Anyways while Im doing this shyte Im thinkin of tackling the handle bar situation. Ive been havin a blast readin everyones thoughts on the gay clubmans vs. righteous clip-ons. once my tanks innards are sparklin, this will be my next step, and I think Im leanin towards the tommasseli adjustable cubmans or some form of adjustable clip-on.
I want to keep the bike as stock as possible, and if I go with clipons my worry is having to use a different headlight bracket. What exactly needs to be done with regards to adjusting the front suspension if I mount them up top??? And Im guessing the wires need to stay outside but how is that kept from being an eyesore? I think I need a picture book to assist my pea sized brain to wrap itself around the idea. The other option is the tommasseli adjustable clubmans. Has anyone put these on? Any words of wisdom youd like to share'd be much appreciated.
thanks

raced with a set of tommy adjustable clubmans on my cb350 for two seasons, then went to clipons cause i figured i'd never race with ahrmas proddy light class again.

peace,

if you go with clip ons you will have to take off the top tree (watch out for the ball bearings) and slip off the head lamp ears )then slide a universal headlamp bracket on each side then slide your clip ons in place.You will then have to assemble headlamp on to brackets and adjust bars and re fit the top tree.Alternatively you loosen the tree fork clamps slide them out and do the same thing.

The only way you can avoid all this is with clubmans and if your looking for a stock as possible you have no choice but the clubmans adjustable or standard solid type.Anything you do you will have to put the wires outside the bars by notching with a tremel tool the controls so wiring is outside the bars.You can put them inside the bars but you would need skill, tools and pateince for the effort, most run them outside.

Just sliding the fork legs up higher to fit clip ons without considering the fact you are lowering the front geometry, almost two inches to the ground, is changing the handling and handling dynamics of your bike.I wouldnt recommend doing that willie nilly without sound engineering theory to the rear suspension hieght. A bike is not like a car, you only have two wheels and things go wrong, snap finger quick, a car , oh well the ride sucks I f'd up, on a bike you dont want to screw with factory engineering without some engineering theory applied in your reasoning.

Im so far behind ,that I think Im in first.

significantly lowering the bars without also switching to rearsets will almost certainly create a very uncomfortable riding position.

...just soomething to consider.

Unless you are jockey sized and really thin, going to clipons or clubmans without rearsets on a cb750 is pretty much asking for leg cramps and backaches.

Mounting the clipons on top of the tree requires sliding the forks up through the triple trees enough to give the clipons a perch to mount to. YOu keep everything below the trees stock. Usually it lowers the front suspension an inch to an inch and a half. The effect is to sharpen up your steering at the risk of losing some highspeed stability (because you are reducing trail). There are a number of people out there running like this so it has been tested. I even had my bike setup like that for a while but I didn't like the bachache so I switched back. To keep the same suspension geometry some guys lower the rear the same amount (usually using the 11inch lowering shocks), others just install a steering dampner. Make sure your steering bearings are in good order (or switch to timkin bearings) because cb750s have been known to speed wobble over 100mph if the bearing are in bad shape.

as far as the wires, it depends on what clipons or clubmans you get. If you get adjustable clubmans obviously you can't run the wires internally, and most solid bar or closed end clipons you have the same problem. If you get the old style open ended clipons you can run the wires inside and out the end and that cleans things up a little. If you are worried about the wires being an eyesore consider that in 77 honda switched to running the wires externally on all of their bikes, and most people hardly notice. If your stock wire sheathing is shot you may want to use some convoluted tubing to clean then up (its that plastic stuff people run wires inside of in cars and office equipment). Black zip ties also keep stuff from standing out too much.

One thing that makes any low handlebar mounting easier on a cb750 is if you switch to a smaller master cylinder. With fixed clipons and clubmans (espically clubmans) the M/C hits the gauges and is nearly impossible to get setup at a decent angle. Switching to a cbr master cylinder helps a lot to free up some bar space (and also improves the cb750s braking).

i have the tomaseeli adjustable bars and i love em, wish i had gotten them to start with. i'm putting clip ons on the 750f i'm building now though.

some people are like slinkies, basically useless but they still make me smile when i push them down the stairs
