I’m in the process of stripping down and rebuild my engine after I believe it seized because I rode it not realising that there was no oil.
It’s my first bike and want to truely understand it’s workings before I buy a bigger bike this summer.
When I opened the engine up there was a strong burn smell, however so far everything seemed to me moving well. I’m waiting for the flywheel removal tool to be delivered so I can continue dismantling. Is there anything signs that I should look for when determining what needs replaced if the engine was seized because there was no oil keeping it lubricated ?
Hi storm, it’s a mutt mongrel 125 with the Suzuki GS engine.
What did you do with your seized engine?
Everyone I’ve spoken to thinks I’m mad for attempting a rebuild but I’m not in a rush and enjoy tinkering about with things. It will just be handy to have someone who knows engines to get advice from, when the manual and YouTube fail me 😊
Youtube tutorials are your friend. If you don't know how engines work mechanically, don't attempt a strip down. Heat warps etc, let the chap look at it or someone who knows what to look for. Personally, I'd buy a replacement lump and fit that. No oil in an engine is catastrophic. This is a big job. *qualified mechanic*.
Not that I'm particularly mechanically knowledgeable but I would tend to agree with the changing engine idea, given how much it cost me to have an engine rebuild 30 years ago🙄
If it's been run without oil & seized you are looking at new piston & rebore as a minimum. The big end has probably suffered damage, any internal bushes would be worn. As above look for a replacement engine or even a cheap crashed or scrap bike on Ebay.
All of the above. If you want to get back on the road fairly quickly, then it would be far better to find yourself a spare engine. But hang on to the old one and dismantle it methodically, preferably with a knowledgeable friend to guide you through. Then work out what needs to be done and then rebuild it. It'll be a steep and possibly expensive learning curve, but you'll know a lot more about engines and how they work and are repaired by the time you've finished.
