SpaceCowboy 71 Posted June 18, 2024 Thank you @DSM8 for coordinating with your neighbor and meeting with me so I could pick up this moto trailer. Initial to-do list: - 3 new tires - weld cracked frame - Cut off rusted in place ramp - replace deck wood - replace lights/electrical Share this post Link to post Share on other sites
SpaceCowboy 71 Posted June 18, 2024 Unfortunately before I could get anything done to this trailer, my 525 started knocking and bogging. So, as projects and priorities go, the first step in trailer rehab is fixing my KTM IMG_2755.MP4 Share this post Link to post Share on other sites
SpaceCowboy 71 Posted June 18, 2024 (edited) Oil filters and screen don't look great... I think that's the forbidden glitter I've read so much about Edited June 18, 2024 by SpaceCowboy 1 Share this post Link to post Share on other sites
DSM8 406 Posted June 18, 2024 ooo that is gonna be expensive, might be worth looking for a new motor that runs vs full rebuild, if you dig into it make sure to check for crankshaft spreading. Share this post Link to post Share on other sites
cmbthumper 164 Posted June 18, 2024 Damn that's too bad. Hours/miles? Dave Hopkins rebuilt my 07' 450 and i think there might be only one more doing RFS rebuilds. I loved my 525 and love my 450 but it would be tough deciding to rebuild them cost wise. Give the roller to Tom and tell him to make it electric as a project.

tntmo 962 Posted June 19, 2024 I have a GSXR1000 engine sitting here just looking for a home! Yeah, it might be cheaper to find a non plated donor bike? Then you could swap the engine in and have lots of spares or sell off the rest to recoup some of the cost. Share this post Link to post Share on other sites
kkug 151 Posted June 19, 2024 (edited) My buddys crank twisted and it kinda sounded that . As Dave said . same buddy . Edited June 19, 2024 by kkug Share this post Link to post Share on other sites
bajadog 23 Posted June 19, 2024 Just in case (I'm not associated), this shop is really talked about on KTMTalk for RFS engines. CTracing 2 Share this post Link to post Share on other sites
Mr.JAJA 409 Posted June 20, 2024 Can you make a BMW 1150 motor work? I have a angel grinder and stick welder. 1 Share this post Link to post Share on other sites
tntmo 962 Posted June 20, 2024 There’s a 2003 on FB marketplace for $1500 right now with $800 back fees. Would make a good donor possibly? 1 Share this post Link to post Share on other sites
robertaccio 435 Posted June 21, 2024 for info look into replacing those paper filters with a micro stainless steel mesh filters. They are super durable and reusable after solvent cleaning. example PC RACING STAINLESS ULTRA OIL FILTER – Taco Moto Co. used for years on all my 4 strokes for racing and trails. (PS all our aircraft filters (both Hyd and fuel sys) are this type. Share this post Link to post Share on other sites

CTracing Thanks for the link. Looks like they have a connecing rod kit for $180 and will rebuild my crank for $110. I also like that they're close by (LA). If I can get this bike going again for less than $500 I'll be stoked. I'd love to get the engine completely gone through by a professional shop that knows the rfs, but I cannot justify dropping $2500-4k on this bike. I thought about buying a used cheap rfs as a donor, but then I'm taking another gamble on a 20 year old bike which could be on it's last legs Ya'll are crazy with the motor swap ideas. The 525 is already more power than I'll ever need. On 6/21/2024 at 9:13 AM, robertaccio said: for info look into replacing those paper filters with a micro stainless steel mesh filters.

I have to decide which project to work on or go riding, so this might be a slow build. But I plan on rebuilding the bike myself.

SpaceCowboy 71 Posted September 3, 2024 crank feels great. Piston got some wear, maybe ate some small metal pieces, but looks surprisingly nice. I've got a wosner piston on the way. And some ebay pre-owned rockers and cam and new gaskets too. I'll clean the bottom end out as well as I can, but won't be split the cases. Share this post Link to post Share on other sites
SpaceCowboy 71 Posted September 3, 2024 (edited) Valves look fantastic. I'm thinking/hoping this bike was recently rebuilt with that new crank, piston, and valves. Also, the internet says this rocker bearing failure is uncommon on RFS bikes. Do ya'll think I should replace the bearings on the pre-owned rockers? Or only replace them if they feel crunchy or loose? Edited September 3, 2024 by SpaceCowboy Share this post Link to post Share on other sites
tntmo 962 Posted September 3, 2024 I know someone else that had the same thing happen. Maybe it’s not common, but you’re not the only one that’s been down that road. 1 Share this post Link to post Share on other sites
DSM8 406 Posted September 3, 2024 you have it this far apart, only makes sense to replace what you can that is in your budget to give it the best change at longevity if you intend to keep it. Now about that trailer........ 1 2 Share this post Link to post Share on other sites
