I see you found pic of my bike tricky trev
Trickytrev, welcome to the assylum
Its on over Easter next year so you would have 2 days either side.
Great if you could bring the CM out for a spin.
What does it sound like?
Well I am more than a little chuffed today
I just won this on ebay this morning, which gives me all the parts I need to finish the XR460Four build. It is pretty close to home too.
Its an old XL250 with a XR Disc brake front end. I will be surgically removing the Front end, swingarm as well as many other bits. The seat will be great too.
The motor needs work but might be good in a Frankenpostie one day
Well I picked it up, 1985 XL250R with XR front end. Realy Happy
Disc brake front end and pro-link rear end.
Unsure whether to run the Prolink or twin shock.
As I am on Holidays for 2 weeks these will be waiting for me when I get home
What wheel size would you prefer to run.
Twin shock should be 18" and that pro-link should be 17".
Well it would be easier to plug and play and run the 17"
Havent really pondered it. I imagine the 17 was run due to space requirements for the prolink setup.
You know I have an `85 XL350 frame and front end sitting in my shed
What engine are you going to run . . . . . . something 2 stroke I hope
Also the prolink swingarm is easy to lengthen for an 18" wheel and adds a bit of stability especially if the donk going in has a bit of extra power.
I appreciate your input.
Anyone have one of these Acerbis Front disc covers to suit a Honda XR laying around??
Well looks like my run with this adventure is done More specifically the charity ride.
The missus informed me last night we'll be in Bali over the easter period and that puts an end to proceedings :ddog
I might still buy the little project I've been looking at though...then I'll be ready if there's another ride.
Have fun guys
We'll miss ya . . . . .
what if we put in a DFAT Travel Warning
We will be making this an annual event
yeah the DFAT thing would be cool - she won't argue against that
Glad to hear it's going to be annual - so I'll go ahead with getting a little project going
Im on holidats for two weeks up in Forster, enjoying the wife and kids enjoying the beach. Only problem is being so far away from the Skunkworks I wake in the night thinking about this bike.
I have been mulling over the front end rebuild and have a few questions abou the steering head bearings:
I need to know the dimensions of the steering head bearing sizes on the XR250 and the sizes of the CB400 Four replacments.
I tried to find a listing on steering head bearings but no luck.
I know I can pull them out but the bikes are 3 1/2 hours south of here
xlx250r which is the same as xl250r has the same 'replacement bearing as the xr250r '85.' part number 91015425832
now the headstem bearings in the shed of the xlx250r are E32005J, pickup the new pair tomorrow.
the dimensions are here,
or 25mm inside diameter, 47mm outside diameter & 15mm height.
I hope this helps you sleep at night and do enjoy the holiday.
Just found the sizes for the CB400Four is 26 x 48.5 x 15
So now I have to find a bearing that has 25mm ID 48.5 OD and 15mm height or there abouts
I will keep searching
I work in ag stuff, so thought I'd check out aftermarket bearings for your hotrod (like Fafnir, Timken, etc).
Bottom line, bugger! I can get part no. 30205, which is 25mmIDx52mmODx16.25mm tall, but that means reaming out the headstock to suit, or you could use the XL250 brng set, but that means shimming up the headstock with 0.75mm thick tube, so haven't been able to help, sorry man.
At least you know what your up against now I spose!
Did something similar years ago, and reaming out the headstock, then fitting a machined-up inner pipe to restore strength was how I went, but I'm sure you know what you doing man.
Thanks for the research.
I will have to pull the front ends off both bikes and see what I have to play with once a rule has been used.
I may have to machine up bearing carriers for both bearings and weld them in place in the steering head.
Been in the back yard, as I just got back from Holidays, and giving the XL and the 400 a bit of a look over and a measure up.
Front will be pretty straight forward. I will need to build a new stem and bearing carriers.
On the back it will be a big effort to get the Pro-link rear end on it with out butchering the frame. Maybe just butcher it. I will pull the remnants of the engine out and get to see the frame clearly and work out the bracketry.
So a mini poll if you will indulge me.
Should I paint the 400's frame and what colour???
Black - Its a scrapheap bike, dont bother
White - Factory Dakar bike colour, not sure which factory
Red - Scientifically proven that it will go faster
Blue - Cause it will look okay and annoy the Yammie guy's
Rainbow - Cause I love trees and whales
