I Bought a $600 Suzuki RM125 Dirt Bike. Will it Run?

If you press the crank, pie scribe both sides for alignment so its faster to reassemble for balance. (Pie scribe means 90% 90% 90% 90% lightly enough to see) so u can align close when re-pressed together. u have to make sure the weights aren't sheetmetal covered put a wedge between halfs but not on weights. You need a press a set of V-blocks and a dial indicator. With all the stuff I see u do its not to hard and cost effective $100 rod to a whole crank $650. O I almost forgot as bad as your rod is you have to cut pin off because you don't want scored area to get pressed through as it will groove the crank and make it junk. Most crank rebuilders use thin cut off wheel and cut through slit in bottom of rod all the way through pin. And press off pin halfs then

I bought a 91 rm125. "engine needs rebuild". When you kicked it over, you could feel something grabbing. I pulled clutch cover off, one of the springs was stretched out and grabbing the case. Someone broke a bolt off on the inner stud, and put the spring back in without a bolt! I threw a set of yz springs in and was riding it 20 minutes after I brought it home. $90 bike, $0 fix. Sold it for a grand. But unlike you I washed it up really good, I use wheel cleaner, toilet brush and sos pads. Made it look great.

I don't know where you sent that crank off to but I bought the rod kit I got only costs $80 and the guy I let rebuild it only charged $200. I had the option of going to Independence County Off Road and rebuilding it myself for free there because they didn't want to charge me since they weren't a Suzuki dealer and didn't want to be liable for it. Which was really cool of them. But since I don't know how to true them I just took it to a guy here in town who rebuilds dirtbikes professionally. $200. I live in Batesville AR btw.

You mentioned something about crankshafts on one of your dirt bike videos. You have as a guy down here in Washington. State that does it for about a 150 bucks to 200 bucks. Depending on how bad the current is, he's a good motorcycle. Mechanics been doing it for years

[@tomalealso]

my brother and I bought a blown up suzuki 90 It had oil injection and I think He never filled the tank with oil, He had a big bore kit in it. the cylinder was ok but the piston was too much money so for 4 bucks we bought a new stock piston and put the stock cylinder back on., a few weeks later the rod bearing went out. I think we had not been careful to clean everything up so the debris from before destroyed the crank bearing. we pedals our bikes across town to a guy who rebuilt the crank for us. I think we paid 50 bucks to have it rebuilt. that was 50 years ago, we have learned a lot since then. never stop learning. I have seen them done a number of times but have never rebuilt them myself. I have been thinking about trying it myself, I have learned a few things in the process and would like to know If I am capable. Is probably more difficult than I think it is, love he videos

[@williamcrowder9814]

I have found when buying a bike one of the important things you should look at is the frame rails make sure that they are straight and not all dinged up

[@christopherknee5756]

My brother's first bike was a used Suzuki 250 street scrambler. My brother stripped it down and re-assembled each part getting everything back into specification. When setting the rear wheel alignment, we went according to the ruler stamped onto the swing-arm. My brother takes it for a ride but comes back saying the bike is pulling to one side. When my brother rode straight away from me, it looked like the rear wheel was not inline with the front wheel. We tried ignoring the ruler on the swing-arm and it got the riding better or straighter. However, the rear wheel wasn't straight according to the swing-arm ruler. Something had to be up! Then one day, my brother had the gas tank and the saddle off and I was standing behind the bike. The large main "back" tube of the frame (under the tank) was skew relative to the rest of the seat frame! This damn bike had been in an accident! No wonder we couldn't get it to ride straight! So takeaway is: check to see all is straight before buying.

[@auroraRealms]

Four possiblities of rod failure: 1. Exceeding max RPM, 2. Overheating, 3. Improper oil/fuel mixture, 4. Dirt in the engine (could be from rebuild, or from letting dirt though the air filter).

When your marking for the timing, look into a "Automatic center punch" you can mark the location on both surfaces. You can clean everything and the punch marks will be deep enough to see and help during rebuild. The Snap-On dealer has them, the cheaper ones wear out and do not have the hardened tip like the Snap-On

[@nicholasdoneen7860]

My 98 RM 250 is a beast! I had the jug sent in to be re nickel silicon plated and I had a Suzuki powersports store do all the rebuild work. I saw the crank had heat marks on it and I asked them about it they said it was normal only to find out on the first ride after break-in that it was in fact not fine and the crank bottom end bearing took a dump. 😂 so I got a free rebuild from basically top to bottom after they finally found a bearing after like 6 months.

For your info guys, these RM-125 around 1996 really didn't like being reved-up un-loaded (like winding the engine on the starting gate @ the races). I could explain what was the problem, but it's a long story. To make it short and sweet, the big end's bearing CAGE was too heavy , had less rolers then ideal and the bearing SLIPPED, and wiped the oil on the crank pin, making steel to steel contact :( . Just avoid reving the engine un-loaded as much as possible!.

This comment is a bit late (only watch it for the first time today), you're probably done and dusted with this bike by now, but do you think the crank pin wasn't replaced when the new rod and bearing were installed? And that's why the new bearing failed? As far as I'm aware, the bearing uses the crank pin (and the rod) as a race for the bearing. I've only had 4t cranks rebuild so it may be different for 2t, but the last crank rebuild kit I bought was a rod, big end bearing, and crank pin. Anyway, great work, loving the videos. :)

Can't see how that engine has been rebuilt recently judging by the way it came apart and nobody does an engine rebuild that cheaply. Looks like the previous owner was taken for a ride. Forget ebay for crank rebuilds. You need an engineering shop that works on motorcycles. We have loads to chose from in UK so you must have the equivalent in US. Doubt it would cost $600 either.

Send it to Eric Gorr. I paid $200 total for him to rebuild my '89 cr250 crank. I sent him the ProX rod and big end bearing ($120) and he charged $80 for labor and shipping back to NY. I'm surprised you've never mentioned him before. He's only the hands down best 2T man on the planet. Wisconsinite as well.

Me and my 9 year are rebuilding a 2004 yz85 I got for free. I wish I could post some pictures of how bad the motor was. It sat 16 years outside with the top end off so the crank was as rusted as it could get and loaded with mud dauber nests. My 9 year old totally rebuilt the bottom end with oem parts including crank. He had the biggest grin when it fired 1st kick. We have put about 1700 in it and it looks brand new but if not for the experience of doing with my son I probably wouldn't have put that much loot in a 2004.

The heat mark is probably due to the previous repair .torch to expand to extract pin ,use freezer on pin before installed
