What would be needed to put 3.5" front on to 93

[1tinindian]

When I changed to 17 x 3.5 the feel in the corners was like cold custard in an old sock to well planted and following a line leaned over required no effort. It might be from the wheel change... But I also put 89 forks with the RPM valves, new oil of course, 0.85 RaceTech springs, Dunlop Q2 rubber, Blue dots, steel braided lines, Galfer knock off rotors, new bearings... so I am not sure what change made the most difference.

I have all these mods monkeyman, but did them at different times, so I wouild say that it was the fork valve mod that you are noticing the most, all the other stuff is just frosting on the cake!

That is what I got from it, your results may vary!

Well the xjr rim / wheel is of to the local body shop for a colour match so I'm using the time I have to make sure I have all I need ready for assembly.  I have the front tyre, wavy galfer knock offs are winging their way from the land of the rising sun (well china anyway!). 

I have However noticed a few issues.  In spite of comments earlier in this thread advising that my spacers will fit and nothing else is needed. Comparing part numbers and microfiches the 93abs uses different spacers compared to non abs.  Am I going to need to source non abs spacers to make this work?  Anyone got any advice? Any one done the 3.5" conversion to an abs? Any experience? I wanted to have everything ready so I didn't get stuck half way through.

Ok well it's school boy error time, so I need your help to fix it.  The xjr rim is on its way to being ready to put in, but I have realised that the axle diameter on the fj is 15mm and on the xjr is 17mm.  Dont want to drill and tap forks!  I found these as measurements for the bearings needed by each wheel in its original installation

If i remember right, the FJ's are 42 x 15 x 12, and the XJR's are 40 x 17 x 12.

Would prefer correct size bearings but am struggling to find them in the uk. Could have shims made but would prefer to source the right bearings.

Any ideas??  Heeeeelp!

Oh crap, just thought does this mean the spacers that I have coming from boats won't fit because they are for the 17mm axle?

Arrrgghh

Nurse,

What I did was have the rim bored for the stock bearings & axle.

Simple and inexpensive. Still sound after many thousands of miles.

Spoke to my trusted spanner monkey at the local garage (shop for those in the US!) and he has recomended normal XJR bearings and then he will have some 'top hat' inserts made to flesh out the difference.  Its reassuring when you speak to someone and they not only understand the problem, but also how to fix it without even seeing the bike and/or parts!!

There is light at the end of the tunnel!

Well in answer to my own question, a few more bits than i original thought/was lead to believe.  I will post a pic of the final product when i get home tonight but i thought i would do the typing while i had the time. 

So i went with a 3.5" XJR1200 front rim.  The axle on this is a 17mm in comparison to the 15mm Fj so not quite as plug and play as was originally quoted.  I had aquired the xjr wheel and spacer and collar (part no 10-90387-15550-00) for the non abs Fj wheel, before figuring it through thoroughly and realised that the axle size may cause an issue. 

In the end a 'sleeve' was machined from high grade billet to flesh the axle diameter out to 17mm.  This sat over the axle and was the same width as the wheel bearings were apart.  The bearings used had to be 40x17x12 as there was no other easy option.  A new spacer was then machined at same width as the bearing were apart. The bearings and the new axle diameter meant too many variables were evident to make the old spacer fit.

The wheel itself centred up perfectly as well so that was another near miss avoided!

None of the original ABS spacers could be used.

However the collar that fits between the bearing and the fork fitted fine, so at least one bit worked out easily.  The discs fitted fine and so did the speedo drive....however there was the smallest amount of contact between the disc bolts and the drive housing so the smallest of shampfers was taken off, i need to touch these in yet but wanted to leave it exposed so you guys could see what i meant.

Keen to hear what you all think!  Have only riden it back home as yet as we are currnelty experiencing biblical weather, flooding, gale force winds etc.  So as soon as it dries up, i have a bit of time i will be out to carefully scrub in the tyre (michelin RP2 to match the rear) and rotors, so will update on handling as soon as i have had a play.

Ok folks here the finished article





Below are couple of pics to give an idea of clearance mod needed for rotor bolts





Sorry they are a bit out of focus but they were the best i could get on my back, in a tigh space with an iphone!!

So what do you reckon folks? boy done good (in the end) I reckon. Looks pretty sweet, not quite OEM, but not too tricked out either!!

I reckon it looks as good as mine  , , job well done mate, , don't know why you had bolt issues, as monkey did too ??

Hello their; this is gonzajr the bearing number you may need is 6203 size is 15-40-12 front wheel bearing. Bought them at Whisler bearing and drive in Colorado. Just but the dimension on the web
and see if it get you any leads get back to me if you need them and can not find them near you.
