So here’s a question. I have seen a few members that have recently purchased a used bike. Also a HUGE amount of so called new members who have purchased a used bike and have come here “just here for a manual”.
Some have been disappointed with the bikes and or knew they were getting a broken bike with some mechanical experience thinking hey I can fix it. So here’s my take on buying a used bike. Anyone who has followed some of mine and other members posts about what to look for when buying a used bike here’s a few pointers on what to look for.
1. I always check the oil and look for moisture, metal shavings and color.
2. Feel the compression or take a compression tester with you.
3. Check for spark (if the bikes not running)
4. Take a small jumper pack to verify that the starter cycle works and the bike cranks.
5. Look for bent or cracked frame/welding that was done on the frame from maybe a wreck.
5. Mismatch plastics by looking under neath.
7. Bolts on the engine/frame that look like they are stripped from someone taking the bike apart.
8. Any kind of scilicone or gasket adhesive that was used on a cover plate or engine seem where the engine was taken apart.
9. Patches on the exhaust pipes with sheet metal or jb weld patch material.
10. Wiring messes on the harness like bundles of tape where the harness was opened up and taped up for an after market device or just plain butchered up.
11. Put the bike in gear (running or not) and roll the bike back and forth to see that the gears work and you feel resistance like the engine is trying to spin while pushing it forward as if you were push starting it
12. I keep a vin# decoder website on my phone as a favorite to double check the year of the bike .
All though nothing is fool proof these tips will help you along while buying a used bike. Not only that but it will help you negotiate a fair price for a bike that may have one of the above problems.
I have minimized this entire process down to about 15 mins. I buy all the time so I don’t expect you to do the same or have a compression tester etc but use some of these tips when buying and go into the purchase with confidence!
I would like to hear anyone else that has any input on buying a bike and what to look for!
Following on from the brief interlude in the "introducing myself" thread....
In a nutshell, I acquired a YFM250 Moto 4 (1991) for cheap recently with the previous owner citing "no spark, needs a new magneto coil and I don't have time to fix it"... anyway I am dubious that the magneto/generator is the issue and thinking more along the line of ignition coil as after a clean up of the magneto I was able to get a rather decent voltage reading off the magneto with pull start and resistence readings seem to check out that the magneto is all ok (all 3 x phases = 1.2 ohms and no run to ground)
None the less I ordered a new Ignition coil and Magneto/generator coil and am waiting for them to arrive.
In the mean time I cleaned up the current Magneto, popped in a new battery and sparkplug, checked out all the wiring harness, all seemed good except I came across the "neutral switch" wire was broken.
After wiring up a new neutral switch wire, the neutral light now comes on (small win) and the starter relay (attached to rectifier) now clicks. If I hit the starter switch on handle bar the starter motor spins and if I pull the cord starter I get a spark on pull....YAY!! I'll try and attach a video below if possible.
So onto the starter motor. Starter solenoid seems to work A-ok, even if it looks crappy and starter motor spins as it should when I hit the start switch....but here is my issue.
When the starter motor runs it turns Cog #1 and Cog #2 (see photo below)....but the chain in the back of the starter which I assume is the timing chain, does not move and there is no apparent movement of the piston in the cylinder.
If I turn it by hand (per photo) or with the pull starter however the chain moves and the engine turns. However cog #2 rotates but not fluidly with the "Crank" (part I turn by hand) for the lack of a better word to use if that makes sense?
Is there a grub screw or similar on Cog #2 that fixes it to the center shaft to make it all turn when the starter motor is run? Could there be a part missing? Previous owner had the starter apart so could be possible?
The outer/front part seems to be on a key-way so not sure how to remove this easily to check how Cog #2 is attached.
What am I missing here?
