Title: upgrade to 35mm forks
Post by: chuck on December 02, 2006, 04:15:01 PM
Will 35mm forks fit in the triple clamps on a 73 125 six days that wer originally made for 32mm?

no chuck, they'll be 3mm too large. you would have to have some maching done and it would probably weaken them its a lot easier to just get a set of triple clamps off of this site or e-bay. i see them on there fairly often   by the way,  how's the shoulder?  [?]

The teachers were right-Math does come in handy.

Believe it or not I was a math major!

My thought was that the pinch bolts would open enough for the extra 3mm. Guess not.

So, I'm going to use 35mm forks with triple clamps from a 175 Jackpiner. Anything else I will need to know that doesn't reguire high math.

Thanks guys,

Chuck

If I remember correctly the spacing at hub is a bit different and maybe the axle length.  I am not totally solid on this but that is what I remember.  Good luck!  The 35's are way better and you will enjoy more.

Chuck,
  The only thing I remember on this change is get the tank all the way down in the front...in other words be sure you don't have too much padding underneath the tank.  I saw a nice tank damaged this way because the top of the triple is larger than the 32mm.  Like Larry says, and Larry knows, you will love the ride.

Chuck,
 The axle that came with the 32 mm forks is different than the one the 35 mm's will use. You can machine the one from the 32 mm's to work.
 Slip the wheel on with the 32 mm axle in place. Check with a ruler the distance between the fork sliders. You need to have  the rim centered, enough thread on the axle sticking through  the fork slider to bite the ny-lock on the nut and stick out 1/2 a thread or so. When you get the axle fit right. If the rim is  off center of the sliders you can center it with the spokes . Off set the rim from the hub center enough   to have the rim equal distances from each fork slider.
 We did this to my bike back in 02. On my bike we machined  the thicker part of the axle the handle fits through  to allow the threaded end the nut fits to get enough thread in the nut. On mine we moved the handle out on the end and welded it in place.
 Easiest way is to get a new axel from Al if he still has them in stock.
 Hope this helped ,
 John D.

John,

I think I will go with an axle from Al.

Thanks for the help.
