Now that the 86 T3 is finished it’s on to the next project. Going to be building a 500R with caverider, he no longer has access to the internet so I will be posting the progress for ya’ll to follow. In the very early stages of the build yet but we are making some head way. This weekend we rebuild the front forks and did an old ice racing trick to lower the stance of the bike with out changing the rake. Here is the standard fork set up.132765

If you swap the smaller spring for the larger you can make the fork about 2 inches shorter with out sliding the forks up the clamps. You could take this a step further and put both springs on the bottom of the fork lowering it about 5 inches but you will have almost no suspension travel what so ever that way.132766132767132768

Note: This will only work on 85 forks, 86 uses one long spring on the top of the fork tube and one small on the bottom instead of two springs on top and one bottom in 85.

Im gettin a woody !!! Cant wait to get her on my lift and tinker my little heart out !!! I must say,if it werent for friends and 3ww than we wouldnt have had nearly the same quality jobs completed in such a short time. I believe the term "BROS BEFORE HO'S" has proven itself here today...(SORRY HO'S)

How you likin those front tires?
What are they?

Carlisle trail wolf. Good price and they get the job done, I like the look of them, they are about in inch shorter than stock. Plus if your bigredridr you can run it backwards for better breaking (inside joke).

Looking good. You might get that together before i finish my tecate, that would really boil my kraut. What did you guys come up with in regards to the kick starter? removable fender?

Cave Rider

Oh it runs, and as I recall...its the reason you have to build a 500R!!

Cave Rider

10-15-2011, 10:56 AM

Oh it runs, and as I recall...its the reason you have to build a 500R!! Actually im building it because im done with the kids toys..lol !!! There is no replacement for displacement !!! I would have done a tecate,but someone bought it out from under me..jkjk

Sure there is....500 displacement is easily replaced with many other 250R based cylinders :Bounce

update: 134021

caverider should be getting parts back from powder coating today or tomorrow, so I would guess it will start taking shape rather quickly. More to come!:Bounce

I have just received the plastics (all black),i will also be utilizing controls from a 2011 kx450f. I wanted to use something new age which allows for custom levers and a more slim feel. I hope to recieve the 10" front rim shortly,as R-TIFACTS has just been kind enough to handle the purchase for me. I will also be sending a seat to Mrs. Mosh for a custom cover. (I WOULDNT SEND IT ANYWHERES ELSE) as her work is absolutely stunning. I would also like to thank R-TIFACTS for creating this thread for me because i am lacking in the tech. dept. and also to bigredrider for his welding/fab skills which has also made this build possible !!! And to all the rest,thanks for the compliments and support during this build. - CAVERIDER

Well after a small funding delay (Something about he had to buy the wife a new car if he wanted to finsih his "toy".) caverider is making some progress again on his 500. Got the 10in wheel in from xowner and mounted up the tire.136381 The front end is taking shape and it is starting to look like a trike.136380 He is currently re building the motor and looking for a good 85 86 cr500 right hand sidecase. The water pump housing has rotted through, if anyone has one please contact caverider or me and I will relay the message. More to come soon!
