engine

Hi Guys (re-posted here instead of Garage) I have a 1980 CB750C I am rebuilding, and while I have the engine open I am curious if it's possible to increase the stroke by using the crankshaft from a cb900f engine. If so, are there any additional parts I would need to make that work? I am boring...

Hi Guys, I have a 1980 CB750C I am rebuilding, and while I have the engine open I am curious if it's possible to increase the stroke by using the crankshaft from a cb900f engine. If so, are there any additional parts I would need to make that work? I am boring the cylinders from 62mm stock to...

my Honda is only firing on the 2 and 4 cyclinder. I have replaced coil ,cdi and still it nothing what else can I do.

Hi there all, hope you've been well. It's since long ago that I have an oil leak from where the ignition pickups' wires pass, in the rear part of the left side cover (not the "points" cover, but the one behind it, on which pickups are mounted). There's a rubber grommet moulded on the pickups'...

I did a valve clearance check today, the numbers looked like this (from left to right, sitting on the bike) - Exhaust - 0.004, 0.009, 0.002. 0.002, 0.003, 0.003, 0.004, 0.003 Intake - 0.004, 0.004, 0.004, 0.005, 0.004, 0.003, 0.006, 0.004 The compression test I ran the other day gave these...

All I want to do is check my valve clearances, should be simple- right? Bike was running fine most of last season, but poor starting made me decide to take a look at the valves before timing and carbs... Issue one; when the end of my camshaft is at the position stipulated in my Clymer manual...

Hi one and all, Need guy here so hello and high fives to one and all =) I'm working on my '81 CB750K, total novice (bought the bike a few weeks ago - cleaned out the carbs and got it running a few days ago but it's a long way from purring like a kitten), and going through the owners manual's...

I was wandering if any of you knows what the GE stands for; i can't find it anywhere? usually the number is only with an E, can someone give any advice? it is an engine i am about to restore.

I had to use an impact screwdriver to get the screws loose on the two outside cylinders. The issue is that I can't get the finned "collar" far enough out of the way to get at the screws with anything other than a normal screwdriver. They hit the frame before they slide far enough down the pipe...

Hey all! Removed my headers to replace the rotten muffler a while back and now I cannot for the life of me get those little "cup" things into the head and put the exhaust on after. I am referring to the metal "sleeves" that are in between the crush washer and the header itself. I have...

Can I replace the countershaft seal on my '70 KO without opening the case?

I'm in the process of rebuilding my 1980 cb750f and was wondering what I should be replacing? It has 45,000 mi. On it, the Pistons and cams look good, I will be replacing the rings and all the seals and gaskets, can the valves be ground on these? I'm the origional owner but the bike has not been...

Well, I am just getting around to tearing down my 1980 cb750f and when removing the cam cap bolts three of them broke off. Any suggestions?:bike:mad

The bike was diagnosed with low compression today. Too low. I got 120 psi on the two outer cylinders and when I squirted oil in there and retested it went up dramatically, leads me to rings/cylinder compression. Really strange because the bike runs well. Doesn't burn oil, etc. It just has this...

Hi guys. i was doing about 80 today on the highway on my 72 cb750 and when i tried to move my feet to the back pegs, they felt slippery... I looked down and indeed... wet with oil. i pulled over and checked the dipstick... wasn't dry - saw some oil down there in the bottom of the reservoir - but...

Hello all , Very new here in a new hobby ... Recently I aquired an Old '73 K3 CB750 . Will have to rebuild the engine . Maybe some light tuning to 836cc with some of the existing kits ( pistons, valves etc ...) Found out that the cilinder head has one helicoil in one sparkplug . Since I may...

Can you use a 1969 crankcase with everything else from a 1974 engine?
