Re: Hello

Michael, sorry bin a tad busy last little while, runs, just, but gutless. Had carbs checked over by professional but not made any difference. By a stroke of luck I managed to score a running engine, but due to unforseen circumstances, ie, a bloody heart attack, it's not been worked on for a bit. Mo...

Re: Advice on replacing gaskets

The only thing I can think of before you start work is to get a piece of thick cardboard and draw a rough outline of your rocker box cover and punch holes through the card for each of the 22 bolts, the bolts are three or four different sizes and it will save you a lot of fiddling about on reassembly...

Re: Dumping gas between carbs?

If Permatex is gasket goo then I'd be willing to bet that the PO didn't use any new gaskets, you shouldn't need any type of goo with new gaskets other than to tack the gaskets in place to aid assembly.

Re: air box

Hi Nick and welcome. That old chestnut again, my thoughts are to stick with stock but I'm sure there are plenty out there to disagree :lol: I like factory standard bikes because here in the UK CB650's were never that popular, well the C's and SC's weren't anyway. You may find some useful info from t...

Re: Dumping gas between carbs?

Hi Brent, when I rebuilt my carbs I had no choice but to buy carb repair kits from Taiwan, they were pretty useless TBH, I just used the float bowl gaskets. I ended up buying selections of nitrile O rings from ebay as none of the kit O rings fit and I was dubious about using the brass parts. Now Dav...

Re: This is how you post pictures

I find the easiest way is click on Post A Reply, click on Attachments then Add Files which opens a window to My Documents on my PC, click on the picture I want to post (having first resized it so the largest dimension is around 750) and then click Place Inline. nighthawk exhaust and top end build 00...

Re: Dumping gas between carbs?

Hi and welcome, we were all new to bikes at one point so don't let that worry you :wink: The carbs are numbered left to right as you are sat on the bike, the far left carb is number one, the far right carb is number 4, this goes for cylinders as well. The pipe that I think you are referring to is yo...

Re: Advice on replacing gaskets

Hi, I personally would replace the cylinder base gasket because it may not leak now but when you undo the head bolts you may disturb it, imagine how you'd feel after doing the top end gaskets only to have the base gasket start blowing after you've finished the job. Another very important thing to re...

Re: neutral switch stays on...

Hi, the only time I have ever had a problem with the neutral light on all the time was when I trapped the wire between the engine casing and side cover, I managed to put a tiny nick in the insulation.

Re: RPM ISSUES

What flatlander said, my money is on your timing advance weights as well. They seem prone to rust so you should take them out, strip them then clean them up and lubricate them. My advice is to take pictures before doing it so that you put them back together correctly.

Re: Newb. Rebuilding engine. What parts should I order?

Hi Dustin, it depends where you are as to the best parts site. If you are in the US then Partzilla is pretty good but if you are in the UK David Silver Spares is my go to choice. Does the motor need new rings? I wouldn't bother if it doesn't, why spend money that you don't need to. Gaskets are a mus...

Thanks for the info

This is the part that I used, it fit straight on with no mods other than an old handlebar cable adjuster placed in the cable clamp to give the extra lift.

Re: My New(someone’s old)1980 cb650

Hi MikeD, I put a metal choke pulley on a set of 650 PD carbs from a Honda 750 but I can't remember which model 750 it was. I never actually got around to fitting the carbs on a bike but the metal pulley fit ok, would have just had to use a choke cable adjuster at the carb end to give the cable a bi...
