Project I can't leave things alone!

@gareth_iowc Sweeeeet. Dream project, those 86/87' YZ125 engines are a funny engine, think they were rated at 24hp?
You could expect to see 9-10 more HP and substantial torque with your 98' engine.
What are the dimensions for your bearing cup? Alot of people looking at fork upgrades
-
Evening all,
Follow @Calum guide - https://dt125r.co.uk/topic/17/usd-conversion-bearing-cup-method
I don't know the measurements off hand as the machine guy did it. It was dam close was only a millimetre or so out..... well that's what he told me.
Calum's guide is great just take that with your yz forks, new yz top bearing, new dt bottom bearing and the frame to a local machine shop and they should work some magic no problems at all.
One interesting think was the stops on the yz are on front centre of the fame and the dt has two rear ones. Luckily it gives the correct steering angles with no modification
Winner.Little update today the yz 125 rear swing arm turned up today. Would have been great but it doesn't fit.
I was surprised to find it's not as wide as the original dt one at the frame. It was only cheap and I didn't think it would fit with out some modifications but as it's smaller I'm going to scrap that idea.I would like the dt200 one was it Calum? But I can't find one for sale in the uk and for a good price.

@Darty yeah I'm going to use the 98 as it's closer to the bikes year. Started it finally today as well sounded great. Ears are still ringing.
The 1lx will be up for sale with 0 running hours fresh rebuild. I thought that was 33bhp as well? I'll have to have another look on the net.
-
@gareth_iowc Is the YZ engine a straight swap with no or minor mods required then???
-
Yeah fits but needs a few modifications. Needs custom head to frame brackets and the front engine brackets.
The decider was the fitment between the swingarm and that fits no modifications
-
So the yz rear wheel turn up today
It's 19 inch rather than the stock 18 inch dt wheel.
Looks like it's going to work great only thing I've noticed so far is the yz spindle is larger than the dt.
The calliper carry will need a little adjustment to make the new spindle fit.
-
@gareth_iowc Nice fat rubber you have their bud - looking good so far!!!
-
Got the new bolt for the dog bone to mount it to the frame from fowlers
Just waiting for the rear axle spindle to turn up so I can get the rear wheel fitted
-
Doh!! So the yz spindle is a lot shorter than the dt. So the next thing to try will be to see if I can take the dt wheel hub and fit it in the yz wheel with the yz spokes.
Thoughts?

@gareth_iowc This dude runs a wheel rebuilding service and has a good rep;
-
Thanks
only problem is I don't have Facebook lol.Might try a local bike shop as I've been told it's quite involved with getting it right.
-
@gareth_iowc No Facebook??? Dude your missing out. There are some wheel builders on ebay too.
-
@gareth_iowc Yeah wheel building is a dark art, so I am told.
-
Haven't posted in a while but things are still slowly moving .
The wheel has been with the builder for a week now so hoping to have it back soon.
Ordered the wrong front yz calliper doh!! So sending that back and ordering another. They calliper carry is wider on a 98 then the 97. My forks are 98
.The yz exhaust has arrived as well but I forgot to take a photo. It doesn't quite fit might need a little bit of heat and some bending to make it work but it's not to far off.
-
@gareth_iowc Took 6 months for the wheel builder to build my brothers YZ wheels!!!
-
Jesus 6 months! He's going to have them ready by end of next week
-
@gareth_iowc Nice big knobs - LOL
-
Yeah not sure what it's going to be like on road in the wet haha.
-
@gareth_iowc Just avoid any bends dude!!!
