I'm having a heck of a time trying to get a used 18" wheel from fleebay (probably because we are all looking for one) has anyone bought a new rim and a spoke kit and built a wheel? What brand rim and spokes did you use? How much did it costs for the parts? I know it's tough but I have a whole winter to do it, and I'm tired of trying to find a decent tire for 17".

Thanks.

Try searching local junkyards. There's a pile of 18" rims in mine. Most go for $35.

The back of motorcycle magazines like Cycle World have ads for junkyards. Make sure you know exactly what you want and what will fit your bike. The junkyards don't.

hey guys just another question, if I pu 84-85 xr200 forks on the front do I have to change front tires?? or will the old one work??

[Quick Draw]

Your stock wheel, axle, clamps, etc. will work just fine. And remember, it's

'84-'91 forks, and '81-'83 if you get the cooresponding clamps.

[Hondafmf]

would the CRF 150 front tire work with the CR forks ?

The picture must be a generic clymers manual pic, that happens to have a manual for a quad...but that should be what you need...

For anything that manual doesn't tell you, there is almost surely somebody on this board that knows the answer.

Has anyone tried swapping cams? The ATC200X looks more radical and fits right in. There's a guy in England that has done some research into the XR200 and what swaps. Check out www-staff.lboro.ac.uk/~elvpc/papers/XR200.html for more.

How would like to try it for us, and report back? Everybody has to be a guinea pig at some point...

Thanks for the link. I have seen that site before.... There is a TON of information and reading....some of it useful. I have decided to edit the sticky. I'm going to put "helpful XR200 links" at the bottom of it. This one goes first, now everybody give me some more....

"I put an FMF Powere Core 4 on my wifes 99xr200 and it is way too loud. I have come up empty looking for a quiet insert for this particular pipe."

when i had my 1996 xr200, i had a 125 main jet and a 40 pilot jet in it with stock exhaust and a k&n air filter. and it ran great. almost no hesitation and i pulled hard for a simple mod. i rode in similar elevation and above with no problems. and it started on the first kick every time even in hot summer heat or in the the dead of winter

Back to being a sticky by popular demand.

I did remove it because there haven't been any recent replies.

Sorry Phil, we have been using it as a tech guide and reference point as much as for replying too. Thank you for remaking it a sticky. It is very convenient for us to quickly look up and relook up the information posted in this thread.

Now to add some of my own useful info from my recent experience. I did port and polish my head my self. At my house in my garage. I used a dremel with different grinding stones to port match the intake and actually open it up a hair. I smoothed out the short side radius and straightened the flow path pretty nicely. I did the same for the exhaust and intake. To polish the exhaust side I started off with 400 grit sand paper and worked my way forward until I was using 2000 grit. I then used a buffing wheel on my dremel with some different grit metal polishing compounds to finish off. I forgot to take pics but it's really not much to see. As far as the results I was pretty pleased. The throttle is much more responsive. Power delivery is really smooth. I can roll on the throttle in 3rd gear and raise the front wheel up. Now I am not sure the piston and or cam is stock in my bike. I am sure the piston is not an overbore as i put stand bore rings on the bike. They fit perfectly. It may be a higher compression piston and there may be a different cam in the bike. I honestly didn't think there should be when I had the motor apart so I did not try to determine they were anything other than stock. I am using a slightly longer rear chain which extends my wheel base a hair and should make pulling wheelies harder. All in all I felt the porting and polishing was a nice touch.

Disclaimer: I know I wasn't very detailed but I do not want some kid to grab out his dad's dremel and go start grinding on his head. I have been porting and polishing heads on cars for a long time. I have some experience in what I was doing. If you are not experienced in porting and polishing I suggest you send it out to get the work done. It is possible to hurt flow more than help the flow.
