Rick knows how and I do too cept Rick welds betta. :lol:  I can stand around drinkin your beer and tell ya how. Its really a PITA. You gotta strip the beam down to just the tubes all the narrowing has to come out of the middle of the beam and if you want it to go pretty low then you have to angle the adjutrs back just right to achieve that. I have a guy I can order waterjet cut sideplates and such from ya if you want something real nice.

How narrow you going? I highly recomend a 6inch narrowed beam. Do yourself a big favor get a big metal rod and knock those factory needle bearings outta it and buy BUGPACK bushings and BUGPACK adjusters. Do not use Empi adjuters or bushings. There's alot of lil tricks I'd be happy to share em if ya want.

RECAP" 6 inch narrowed BUGPACK thanes,BUGPACK adjusters. Then get with me on the angled adjusters the angle is the art man. Figure out how low and compensate when you build it. The ride quality will depend on it.
A 6 incher done right rides almost as smooth as stock.  

If you plan on buying  rims at some point you need a 6 inch beam.
At 4 inches you loose the shocks,by cutting 2 inches more off the torsions you stiffen the load on them and reduce the floppyness most 4 inch beams have. Same thing with needle bearings ditch em the thanes keep it snug and provide resistance. If your wanting anything less buy a CB Performance 2 inch beam and be done with it. No matter what get drop spindles for it. It all depends on the look you want.

Are yellow bugs falling from the sky? :lol:

145/65/15's on stock rims 4 inch beam. 2 clicks rear 195/65/15 on 7 inch wide rims. Awesome turning radius but the beam hit everything on the road. But it looked cool. :lol:

Oh and it has drop spindles on it since the begining.

I think they sell aftermarket smoothies in 4 lug. Put some caps on em and nobody could tell.

man I think it was either cip1 or cb I'll check.
I just checkd I'm wrong on both counts.
Samba? Hot vw's add I know I saw em recently. :?

If they still are offered, American Racing used to make 4-lug chrome plated smoothies.  I know this cause a friend of mine bought some for the rear of his trike.
They used a plain, domed hubcap.
