engine

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...

Gday All, I'm in the final stages of restoring a 71 CB250 (K3) and have an oil leak from the top end that keeps plaguing me. I have resealed and replaced the rocker cover gasket several times but it keeps blowing out in the same location which is the corner above the left exhaust valve. When it...

I've been in the process of restoring my Cl175 scrambler and finally got everything put back together, I tried to start it and I got nothing. As far as I can tell I am getting gas, and I know that I'm getting spark as I've tested that. The big issue is that I don't think I'm getting any...

Hey guys. Right now I'm working on a 1982 nighthawk 450 project. I had a seized engine, so I bought and am in the process of installing a new one. An issue I have is that the lever on the right side panel attached to the clutch cable is stuck. Off of the engine the lever on the panel (I'm...

First post, been lurking for a few weeks. To make a long story as short as possible - I bought this bike for a couple hundred bucks. Decided I could make it my project. I’ve done basic work on bikes for years but this is my first time opening up an engine. So bare with me. Apparently this bike...

Hey everyone New guy here. I've been working on my first build (cb350k0). I finally got the engine back together when I found this little dude on my bench. I have no idea where it goes. Can anyone here help me identify this piece? It's super thin.

Howdy fellow wrenches (wrenchers? Wrenchees?), I'm having a little issue as I'm putting my '93 XR250 back together. The first mistake I made was not labeling three wires that leave the alternator and go to the regulator. The manual says they should be different colors but for whatever reason, on...

Justice gets his 1972 Honda CB450 put back together after some serious engine problems and technical difficulties. He can't wait to take it for a Test Drive on a cold spring day.

Alright, I need to get a log started before I loose track of what I'm going to be doing so here goes! But first a little history, Last 4th of July I picked myself up a fair condition 1973 CB450 k5 for 500 smacka'roos! Got the thing home and tinkered with it a but and got it to run! and that's...

I paid a local shop to do some top end work on my CB360. They installed the cam chain tensioner wrong (prove it amirite?!) The tensioner snapped both the metal tabs on top and bottom off and are currently floating around in my engine. I'll be rebuilding the engine myself this time, but I'm...

Completely restored my 1972 CL350K-4 and got about 1000 miles out of it then it blew a hole in a piston. I have a "modern mechanic" who is willing to try to repair and trouble shoot but at what cost. I think I'd be better of finding a completely rebuilt engine and just replace it. Any...

I'm doing my very first bike tear-down and build on a bike that a buddy of mine practically gave me. So, I decided that I want to try to do as much as I possibly can on this bike by myself over the next few years in order to teach myself and have fun. Engines have always intimidated me, but I...

Hey, I have recently purchased a 1978 CB400T Frame and engine and its missing the exhaust. I live in Australia and these things mega rare and parts are even harder to get. What other bikes exhaust will fit on this thing? I am happy to customize a bracket for it, but when it comes to Exhausts...

Hello everybody I have a Honda cm 400 t, and it worked just fine the other day as i was riding around my hometown. However when i wanted to adjust the valves, so that i wouldt click as much i broke one of the bolts. This meant that me and my friend had get to the the remaining part of the bolt...

Has anyone had issues with their stock 71 cl350 choke turning on(lever up) while riding? I guess its not a huge deal, but it is irritating losing power every 3 minutes because the vibration just moves the lever up on its own and i have to bring it back down every time while i ride. Is there any...
