In general you can figure about a max of 350 degrees for the cylinder head...maybe a bit more around the exhaust ports. I'd say more typical would be in the 300 degree range.
Most "engine enamels" are good, but they will discolor around the exhaust ports. Everything seems to eventually discolor around the exhaust ports.
Duplicolor makes a most excellent high temp "ceramic" paint. I use it on headers, holds up real nice...but doesn't even cure till it gets about 400 degrees.
A good way to test engine component temps is to have a good store of small mammals that you can press against the hot engine part. The length a pitch of their screeching will tell you how hot it is.
and an alternative for you peta types out there, i saw a thing on television the other day. its a thermometer for measuring engine parts that you just shoot a beem at the area and it tell you the temp. it was on one of those car shows on speed. just think of the possibilities.
jb, you go by the squeel huh?? i usually go by how deeply i can brand em.
I used to use the branding method..but I got tired of shaving them first so they make positive contact with the engine part. Course with the branding method you can use them more than once, the squealing method tends to make the little critters a single use tool.
Hey all, new here. Just got myself a 72’ Honda CB100 with a CL100 engine swap. Im replacing the lighting and fenders, but I’m running into an issue with finding compatible lights. Everything that I’ve found that is low profile runs on 12v, but the bikes battery is only 6v. Haven’t done a TON of...
Hello all............recently put a new battery in my 69 cb175. Battery died after a week or so. I only rode it for a total of an hour within that time. It usually takes 6 cranks with starter to get her going so i imagine that's draining the battery significantly. I also have an H4 type bulb...
Is anyone running an older DR650 as a stripped down trail bike or desert sled?
I am currently working on one, and trying to find a good exhaust, tire and seat setup. Open to input and suggestions.
In general, will mounting tires sized (110/90 -18F) and (120/90 – 18R) make a difference one way or another if a bike has tire/rim sizes to accept (100/90 -18 F) and (110/90 – 18 R) stock by the manufacturer? No clearance issues being a prerequisite.
Working on a bike that has a sorted history. Don't know any more about the motor other than it is a '83 or '84 CB or CM 450. Trying to figure out if we need a CDI when rewiring with a Motogadget M Unit?
Would appreciate help as we try to determine a wiring diagram.
