Thanks. I have been a lurker on the 13X WERA forum for years.
 There are some very smart & funny folks on there.
 I need to join the group.

 I am in So Cal, but, not near any race tracks. Closest would be
Streets of Willow, if it's still open. And maybe Grange.
 ButtonWillow and Chuckwalla are at least 3 hours away.
 I assume Apex would be too tight of a track to really open up
 the RS125. Since it is mostly a Kart and SuperMoto track.

 The RS is running. At least in the auction video from Iconic.
 It certainly has been raced in it's past. Although I do not
 think so since someone fitted the SharkSkinz body work and new paint.
 Whoever owned it took really good care of it. The safety wiring
 is a work of art. I changed the gear oil and it looked brand new.
 
  In the spares it came with another carb, 4-5 slides. 12 or more
  needles and 10-15 main jets.

 Without removing the top end to check. I am leaning towards the engine
 being a fresh rebuild. Maybe only a couple thermal cycles.
 The slicks are from 2022 and show some gum balls. Whoever rode it had some
 skills.

 Thanks folks for looking at my new toy.

The Avatar is an 1988 SDR200.
You likely saw it at one of the 2 Stroke Extravaganza shows.
 This picture is the RS125 next to the SDR.
 The SDR is small, the RS looks tiny next to it.
 The RS is supposed to be 160# and 40HP?!?!?
 The SDR is a little over 200# and 33HP?!?!?

 My bucket list of dream bikes is growing.
 Cheers, Jeff

Just won an Iconic auction for a bike I've admired for years.
 I didn't really intend to win the auction. Tossed a bid out there
 to see if others would bid it up to what I estimated of the bikes value.
 Got it for, what I thought was a very good price.

 So. Asking the forum if they have any experience or knowledge of the
 Honda RS125 GP bike (s). The person I got it from never did ride it.
 He had very little information from the previous owner (s).
 How many hours on the piston, crank, rings etc.....

 It came with a few spares. Gaskets, sprockets, CDI, Tach, crank. Don't
 know if it is new or used.
 I've been looking to gather as many spare parts as I can  find.
 Would be nice to have enough to do a complete engine rebuild.

 Having trouble finding sources for new engine components.
  I've been looking at RSCycles, and Accu-Products. Mostly trying
 to stay inside the USA for parts.
 Really looking for Piston kits, Base gaskets, Head O-rings. Main bearings
 and main crank seals. etc...
 I was lucky enough to find an owners manual and parts list manual for the
1992-1993 NF4. Pretty sure the 1994 is exactly the same.

 Let me know if you can help.
 I can post more pictures if anyone is interested.
 Cheers, Jeff

Russ is going to be jealous. He has ridden two of them.
 Mine and Andrew's.
Let him know of you ever find another one. I'm sure he would
 be interested.
 Post pictures of your new ride. cheers.

Always wanted a TY when I rode vintage AHRMA trials.
Thanks for sharing your TY.

Let's encourage Russ to change the "Death-Wing" tires with something sticky.

 A complete wast of my time. Only got maybe 1/2 way through and had to
 turn it off. Pictures of some very nice bikes.
 Otherwise worthless. I hate Ai generated videos.

Turning Wrenches / Re: RD350 Oil Pump Question
March 17, 2025, 10:35:34 AM
socal250 or Arrow to the yellow phone.....
 Finding the exact spring might be a problem.
 The roll pin, when you can find the diameter/length
 could be found at McMaster-Carr.
 I'll defer to the real experts here for more info.
 Cheers, Jeff

Interesting! Never heard of this bike before.
 Curious if this is a Derbi Motor? But, 4 Speed?
Wondering if this is correct.....
 Cheers.
