Greetings, everyone, I'm working on a cm450 that's been sitting for a long while and while I got it to turn over, I'm not getting spark. All of the ignition components appear to be in pretty bad shape. I think the coil should be replaced as a matter of course, which is easy enough to find...

Guys, would appreciate some feedback from those who know: I'm rebuilding a pair of VB's off an '81 CM400 for someone and I know you can disable those air cutoffs with an appropriately sized piece of rubber in the air hole, however, as I don't really have a way to cut a perfectly-sized piece of...

I've got a 78 myself. Have you checked for spark by laying the plug against the head and cranking it over? You should see a nice blue spark. On the clacking noise, that happens on mine, too, if I crank too long. What I think is happening there is the gear behind the starter clutch gets worn...

Ok, if the signals don't come on at all right now, you have a wiring problem, so get that sorted first. But, you will still need a different flasher in order to get them to blink at the correct rate. I got mine from Fleabay but you could probably get one from any auto parts store, too. Sent...

Try replacing your stock signal flasher with one made for led's, which don't draw enough amps to trigger the stock one. I used a 2 milliamp flasher for my led strip. They're cheap, you should be able to get one for less than $5. Your stock flasher is probably a two-pronged one, so look for the...

Dude, I did the broom handle trick, then put a 200 psi impact to mine and stripped one of the bolts. I had to have a machine shop drill it out. You might drill it out yourself, if you feel brave. I couldn't believe that bolt was so tight. That drilling cost me an astronomical amount...machine...

Yes! I love to see another 750 being restored to tasteful glory. Mine is below - a '78. Will be watching... Sent from my iPad using Tapatalk

Well, like I said, I've never ordered from them, so do post on what you find. I do know that finding standard pistons and rings for these old beasts are like finding a buried treasure in your back yard, so I hope that place actually has them. Sent from my iPad using Tapatalk

I bookmarked this site long ago in case I wound up needing pistons in the future: http://www.cyclewareables.com/pages/vintage_piston_rings_kits/vintage_piston_rings_kits/vintage_piston_rings.htm Never ordered anything, so don't know much about them, but I suspect you'll need to,call them to...

Btw, here's what came of all my efforts. I call it the Beesticorn, part wildebeest, part unicorn. I hope this pic posts ok... Sent from my iPad using Tapatalk

I wasn't able to get the rear axle trick to work either. I pounded on the end with a sledge and the generator didn't budge. In the end I sprung the mere $18 and bought the rotor puller tool, put it on an air impact, then drove that sucker out. You can get the tool from z1enterprises.com. When...

Actually, let me second advising against any aftermarket gasket sets. I used the Vesra set and every single gasket, except the head gasket, in the set started leaking, some as early as 800 miles after my rebuild. I know it costs more money, but OEM gaskets are the only way to go. You'll have to...

I've got the same bike and once I got it running somewhat properly I absolutely love riding it. It's a wonderfully torque-y, relatively smooth-running engine with decent handling once you do your suspension right. Since you're going to need to do a full restoration, here's a few things to look...

You'd be surprised how difficult points are to set just right, so try turning the timing plate while the bike is running and with a timing light so you can see the effect in real time. Also, try using an unlit propane torch around your airbox and intake manifolds to check for air leaks. I think...

+1 on the rude awakening. Building or restoring get a bike is not for the faint of wallet. I rebuilt a 78 Kawasaki two years ago and estimate I spent about $3,500 to get it torn down, put back together and running after sitting for a long time. I just found out I have a worn out camshaft and had...

Got it running. It was flooded. Took out the plugs, turned engine over a few times, put new plugs in, choke on, it started up. Got it idling, rode it around the park once. I think the PJ may be too rich? Air screws are 2 turns out, any less and I can smell the richness in the exhaust. There's a...

Held the throttle wide open and cranked...no change. Plugs are wet, checked again. I'm going to go get some spare plugs and try a new set, see what happens. Man, I've never not been able to get a bike started...frustrating. The air/fuel must be off somehow.

Yeah, I can't take that dcc jetting seriously. I've read some threads from people who've put their other supposedly pre-jetted vm's on their bikes with horrid results. I'm sure the 3.0's will prove the answer...once I get them going. My plugs are wet after cranking with the enrichers on. I can...

I must be losing my mind. Ok, slides are sitting correctly, no obstructions and the front side is indeed closed. Left slide on the left, right on the right. Same jetting as above, mix screws 1 turn out. It cranks and every once every three or four revolutions thinks about firing in one...
