Any thoughts on the noise going on, it’s near the top end. I’ve already checked for the recall and i’m good since I have the dots, adjusted valves and cam chain tensions. Any thoughts?

So I was riding for a last time in early november 2024 - cool day, end of season in Canada. I was getting to a town close to home, when my engine seemed to start getting really hot, making a different sounds, when climbing up a sloped road going over the freeway , the bike suddenly seized, wheel...

Engine Noise Video I just recently did a rebuild on a CA160, I’ve already followed the manual on adjusting the timing chain and made sure the valves were in spec, I also know it isn’t piston slap. What do you think this could be and should I be worried or what should I do?

I am not sure this issue is carb or electrical related, but after rebuilding the carbs many times and them running fine up until recently, I feel like my issue is most likely more electrical. So, with that in mind, let me jump into it. My 1980 CM400 started running rough about 300ish miles...

Hi all, purchased a '72 CB350 that was in running condition, just not running well. PO said he had it for a few years but never finished fixing it up and had never really rode it. PO stated he had replaced piston rings and cleaned up carbs (but didn't rebuild them) and said he believed the...

My Honda runs great at idle but as soon as you give it throttle, it dies. Carbs have a full rebuild, points are set, valves are set, new plugs, new coils, and a bunch of other new stuff. Needless to stay it is pretty much completely rebuilt and I have no idea how to get it to run with throttle...

I've had my first bike for a few months now (72 CB350) and it came with foam pod filters from the last owner. A couple weeks ago I changed the foam back into the oem air filters and messed with the air mixture screws to get it to idle (started with the spec 3/4 to 1 turn but had to up it a bit...

Hi, everyone. I've got a '75 CB200T that I picked up for a good price that I'm getting ready to fix up and make a daily commuter. Right now the engine is seized and is soaking in Marvell Mystery Oil. The PO said that it turned over as recently as last Spring (2021). Hopefully I can get it to...

Hi guys, short time before I bought my bike (1982 CB450 SC Nighthawk), the previous owner made a repair to the engine with all Honda original parts in June/2019, this is what he changed: balancer chain, balancer shaft, balancer chain slipper, cilinder, cilinder head, valves, valves seals...

Hello everyone, I thought given the state of the engine right now it might be best to make a log thread, since i always have a few questions and I think it's better than to inundate the other sections. So first of all, a little history and a few pictures! I got this bike in the summer of...
