I have been reading about painting the motor. My ? is do you primer first. No one ever mentions it. Just wondering if it is a given or that you just do not lay primer. I am going to be painting my cylinder and head with VHT high temp engine paint. Also has anyone used this paint on their tins? I have read that it does good up against fuel. So, I thought maybe I would just paint my tank with it as well.

Cleanliness is the first BIG priority - and being cast aluminum - oil can seep into all the tiny pores and ruin your paint after you've finished. Clean, clean and clean some more. I've known guys to put engine parts in the dishwasher and got good results - but of course, the wife never heard about it...... or they wouldn't have lived through the night....
Definition of an Expert-
An Ex is just a Has-Been, and a Spurt is just some poor drip under a lot of pressure.........
Looked on the VHT website and I can not decide between the engine enamel(up to 550deg.) or the flameproof(2000deg.). The engine enamel states: They are specially formulated to withstand corrosion, rust, salt spray, chemicals and additives of today’s gasoline blends and degreasers. The flameproof makes not mention of gasoline. They also have a barrel paint. I figure if they use the engine enamel on car motors then it should not be a problem on motorcycle motor as far as the heat goes.
I'd recommend an acid based degreaser - some of the engine degreasers actually leave an oily film behind. the acid degreaser can cause flash rust on steel parts, like the cylinders, so be aware of that. Follow with brake degreaser. I used a high tem[ engine primer and paint (duplicolor). It has chipped a bit through the rebuilding process, and I've touched it up with good results, but not real confident that it will hold up well. POR-15 makes a kit for painting engines that is supposed to give superior results. If I could go back, I would've used that kit.
I was going to start a new thread on painting engines, but found this one. So- I'll tack this on here. I'm also thinking about painting just the crankcase halves, as the rest will be dry ice blasted. I'm also looking at the VHT engine coating in a rattle can, which by the way, says "do not prime". I'm pretty sure that its 550 degree rating is plenty good for a crankcase, but was wondering about color. I'd like to duplicate the stock gray color as close as I can. Has anyone tried the Nu-Cast aluminum color? www.jegs.com/webapp/wcs/stores/servlet/product_10001_10002_749327_-1_10747 Or- does someone have a better idea? Meanwhile- a few shots of the engine work in progress:

joshua: The regulator/rectifier unit I got from Mikes PMA has closer hole spacing than original. Are we supposed to mill the holes to fit?
Jun 7, 2017 19:25:58 GMT -5
joshua: My bad. I found the bracket they supplied to mount the rectifier/regulator... Uh oh. How is this meant to work? Which way is it meant to mount? Looks like I have to use some spacers or something. Good instructions would be nice.

craig8johnson: I'm checking the charging system. I'm afraid I might have fried the last battery. With the solid state regulator (after market) what should it be charging at. The book says, I think, 15 volts. I'm hitting 17 when revved. Is that too high?
Jul 11, 2017 18:06:19 GMT -5
gggGary: Yes 17 volts is too high, about 14 volts is max, sounds like you don't have the right regulator or it's wired wrong.

tt650: Trying to breathe life into a 1980 that's been stored (indoors) for 25 yrs. Air filters are dry rotted. Have cleaned carbs but she only runs briefly on choke then stops. Need jet setting info and other ideas that might help her idle and rev.

trix13: Hey everyone! New to the forum and am fighting those gremlins!! New charging system, ignition switch, coil and fuse box. Resistance is higher than normal on the ignition pick up so I'm trying to find one. No such luck yet.

trix13: Also, even though all of my connections are clean, I cannot seem to find out why , when at higher rpms, I hit the signals and the rpms pulse with the signals...hahah. same with the brake light. I appreciate all input!!

jimothyj: Hello everyone, I just joined & wish would have known about this site in 2014 when I brought my 1974 TX650A back from the grave. I have spent a good deal of $$ and alot of time on it. Just painted it and working on electrical, I will post pics soon,

louisvan: trix13 - I had a problem with my 1975 SX650. When I got to highway speeds, the engine lost power. The problem was in the connectors. At a certain vibration and the wind pushing on the wiring loom, the connector lost continuity. A bad crimp to the wire.
