stem swap question
Im lookin at swaping front end on a bike and easiest solution looks to be swaping the stem..is it just a simple press out or does it needed to be heated up..both bottom tripple clamps are aliminium thanks
Re: stem swap question
Press should work fine, but you could try some heat on the triple if it doesn't move.

Re: stem swap question
heat wont hurt it, but they usually press out fine, tho it does depend on the bike and the triple being used.
Re: stem swap question
If u wanna know jon just ask..dont dance around it..lol its a wr200 front end on a dt200..I got it thinking it would just bolt in..as the dt is the same bolt on fit as dt175 ,rz fzr , r6 and prob a dozen more..but nope the same year wr200 with the same motor they changed it..I know the wr frame is baced on a yz125..any way thanks for the reply..
Re: stem swap question
LOL, I would also have assumed it would bolt right on as well but as you say the WR is based on a YZ not the road bike stuff so will be longer. you could also run spacers, but if the pins are the same and it will fit then thats a more elegant solution you are suggesting
Re: stem swap question
Well the length longer and yes spaces could be used..but the diameter of the stem on the wr is smaller and runs smaller bearingins both OD and ID So the cleanest sulotion is swap stem then machine the wr one to fit the bigger dt one
Re: stem swap question
Or you could check the bearings tables and find a bearing that fits the ID and OD that you need, thats where I usually start. Check the hints and tips section of the RDRZ500's 350 forum as Ive linked the tables on there for this stuff and also axles etc.
Re: stem swap question
Yeah that's the way I would go first. Might be an off the shelf bearing that will work.

Re: stem swap question
Yeah I usually would go that way too..how ever it would also need a 25mm spacer..bit ugly..

Re: stem swap question
check for roll pins OD of the stem under the bottom cone and the OD of the stem under the bottom clamp . WR 200 is indeed a YZ125 frame
Re: stem swap question
very good point Lozza! I should have said that, those things are a mare if you have them in the triples, and you need to remove (probably with a drill if they are deep in) em before pressing of course.
Re: stem swap question
There may also be circlips = press the stem the opposite way slightly to create enough clearance to get the circlip out
One day lad all this will be yours............
