Hey everybody. I haven't been on here since my bike broke, but I tore into it, replaced my broken rocker arm, and painted some parts of the engine, etc. Just wondering if anybody has torque values for the head? Also not sure which oil to use. I heard 20 50? Thanks in advance.

It's got like 17k on it. I did get a spark. I just went to the Yamaha dealer and was told there's also been a bad batch of gas going around? I filled up like 75 miles before this happened but maybe the water got pooled in the carb and it pulls it during high rpms? I don't have a compression tester, but I can't push it in gear so it's obviously not terrible. I'm trying my new spark plug, new gas line, and new gas.

I love this bike, but it only ran for 3 days after i bought it, and then it started to cut out It would basically feel like I was running out of gas and it would sputter out, but then restart afterwords. Anyways, the last time this happened, it just wouldn't start up again. I checked, and it has spark, it has fuel, and it's sucking in air with a clean filter, so what's my problem? I took a look in the carb and everything is really clean. It turns over and I can hear a little combustion but is just wont run. I did notice while holding the spark wire boot that I got shocked while looking for spark. Maybe an electrical issue? Ignition? Thanks for the help in advance.

Just bought a 1980 SR250. I love it and I have a lot of plans for it. I decided to join because it ran great right up until 3 days after I bought it, and then it started to cut out It would basically feel like I was running out of gas and it would sputter out, but then restart afterwords.
