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 all! recently put my engine back together after changing headgasket and the lower engine gasket. I also removed carbon from my pistons and grinded the valves, and changed the valve stem gaskets. so fast forward, putting the engine together goes nice, connect some fuel and on the second try...

Hi! need some advice. Doing a top engine «rebuild» if you can call it that. Upon removing soot and carbon from the top and pistons I noticed some brown/copper ish coloring on the sides. No sign of scratchs on the sides inside the cylinder barrels. Bike ran OK before dissasembly, except some...

Hi All, I recently took apart my CB200 engine and have found that the Cam Chain Bar Tensioner has had a lot of wear and the chain appears to have eaten into the side of the head of the tensioner. Does anyone know where I might be able to buy a replacement, I can't find anywhere online at the...

Big hello from Orlando! I’ve really enjoyed reading posts here and I’m hoping to dive in deeper now that I’m a member😁 I’ve been playing with Honda’s for the past 30 years. I’ve had several 305 dreams, a 1965 Superhawk, 1971 CB750, and a 1990 gold wing. The bike I’m currently enjoying is a 1969...

I have a 1978 Honda CB 400Tii with a Frankenstein motor that is giving me trouble. I found a '85 Cb450SC motor that I was considering buying. Before I buy, I have a few questions: Does this motor have the same bolt pattern? Will it work with my electronics? Can I fit my 21b carburetors...

Hello all! Glad to have found this forum for help. I am a 20 year old college student who is absolutely in love with vintage Honda motorcycles. I purchased a 1974 CB450 about 2 months ago in rough shape, and have been slowly restoring it back as original as I possibly can. HOWEVER!!! After...

Hey everyone, I haven't been on this site recently, so if there is a better place to post this to instead, let me know. I send this to 66Sprint, but in the case he is not active here anymore, I'll post it here too. I have a Nighthawk 250 rattle/buzz that I'm having a hard time diagnosing...

Hello All, I have a 1980 Honda CM400T and I just took the engine apart to replace all the gaskets. After reassembling the engine, I got to the last portion of tightening down the piston cover bolts. (12 & 10 in the image provided) They require a torque wrench, but I stupidly decided to tighten...

I have a 1966 Honda CL160 that I need engine help with in the Sac area. If you have a good referral please let me know. Thx, Mike

Head gasket is leaking and the leak is accelerating to the point where I can't ignore it any more. Maybe the gasket between the cylinder and the crankcase, too. I want to replace those, and I figure if I start pulling gaskets off I gotta put all new ones in when I put it back together. I do have...

With Covid closing everything down this summer, I decided to pull out my dad's CB360T that had been sitting in the barn for nearly 40 years. Externally, it wasn't too bad with rust in some places, but no holes. The engine appears to be in great shape internally, and also has plenty of...

Hey guys, im in the process of replacing a head for my 450 engine. I have had much success in the last couple days. (Even making my own castle clutch nut socket) However im trying to find a shade tree mechanic way of getting the balancer off on the other side. Ive searched the forums and...

Hello everyone, I recently purchased a 1979 CM400T. After a bit of riding, I noticed that there was some ticking/knocking coming from the engine and after research I came to conclusion that I should try adjusting the valves to address the problem. Upon opening, I used the feeler gauge and none...

I’ve included some photos of an oil leak on the cylinder head side cover (I believe). What do y’all think it means? What’s the best action? Thanks for the help, this is my first post besides my intro.

Hey Everyone, Pretty sure this is something I have done when I did the engine rebuild, involving the kickstart spring. When I run the electric start, the kickstart lever just kinda... falls backwards. I can lift it back to the upright position, you can hear the ratchet mechanism, and it can...

Hello all, ive been digging through this forum but couldnt find exactly what I was looking for (because I dont know exactly myself haha). I have finally gotten the opportunity to find a house with a barn that gives me the opportunity to learn more about engines (that I like but have very little...
