Changing rims for bobber project

Want to put a 3/4 rim up front what and or were can I buy updated rims to put on my xj750 were the front could be a 3/4 axle up front rim any help please the rear is a shafty

 

The rear wheel has splines for the rear diff and a brake drum incorporated into it. The front rim is set up for dual rotors and spaced for the brake calipers. You might be able to find a different style wheels from another Yamaha of the same time period but aftermarket "updated" wheels are going to be tough to come by and I would suspect expensive.
What kind of look are you really after? Some guys want wire spoked wheel in the front. I think they find a front end from another bike and do a complete swap.

 

I am putting a springer front end on bike the stock axles are 1 inch the springer is a 3/4 inch I'm just thinking usein the stock rims and just getting a front axle reducing kit just don't know we're to get it at

 

You will need to either make a bore reducing sleeve, find bearings to suit, or modify the axle bores on the forks with a split sleeve.

Stock axles are not 1 inch. Stock axles are metric.

go to local auto or bike machine shop they can find bearings you need , or make a bore reducing sleeve for you.
does the high school or trade school near you have a machine shop they will usaly do the job for cost of matrial

 

If your springer front fork is truly in inches vs metric you are going to have to have axels custom machined to your needs. How are you going to incorporate front brakes into your new fork set up? Front brakes are going to be about 70% or better of your stopping power.

I was thinking the Stock Yamaha Front axel would not be working so good on an aftermarket fork setup. Hence a custom fabricated axel would need to be made with shims and reducers to work correctly.

 

I have a pretty reputable machine shop down the street I'm going to go over there with the forks and front rim and see what he could do then thank you for your response
