Brakes.
I forgot to mention yesterday that some bikes are coming through with undersized caliper mounting bolts. I would remove the caliper, and run the supplied mounting bolts into the fork leg about 1/4 or 3/8 of an inch and see if they wiggle around in the threads on the fork leg. If they do, do NOT tighten them up tight in an effort to "git 'er done". Go to the GOOD hardware store, and get the right bolts. Personally, I prefer Allen screws. They seem to be made better. If the bolt you take out is shouldered, use the same Allen screw to replace it. Put anti-seize on the threads...ARH

Another thing to check is the exhaust bolt directly beneath the air box. If this rattles out then the exhaust oscillates back and forth until it cracks off the top exhaust stud in your cylinder head. Fixing that sucks.
Put red loctite on the exhaust securing bolt beneath the air box. If you want redundancy, drill and safety wire it, or put a hose clamp around the exhaust and frame. I was on a 400 mile ADV trip with two friends, all three of us were on hawks (new as of Memorial day), all three of us had this happen during the trip. Don't be us.

I would recommend against loctite 272 (red high temp high strength) for that bolt. They make a medium strength high temp blue. Same thermal capability, but wont be a total pain in the rear to get off. It is known as loctite 246.

Registration.
Except for three states, most registation issues are the result of the MCO or MSO stating that the Hawk is a dirt bike. It is up to YOU to make sure that whoever sold it to you states "motorcycle" on the afore mentioned MCO/MSO. The three states that know more than you do about what you should own and ride - California, New Jersey, and Pennsylvania. Yes, you can solve the Jersey/Pa problem by first registering it, by mail, in Vermont, and then transferring it to your home state. California is hopeless. Don't even try it....ARH

Carburetor Magic
I just realized that I glossed over something on carb tuning in previous discussions of this system. Unfortunately this solution only works on Mikuni Carburetors, because Mikuni is the only outfit that offers interchangeable throttle slides. Now, if you prefer to roll on the throttle, the slide that comes on the carburetor you bought is adequete for the job. But if you like to grab a big handfull of throttle, then the standard throttle slide is too lean. You can cheat a little by going a little richer on the pilot jet, but it is easy to have an over rich idle that way. So the answer is less cut-away on the throttle slide. Less cut-away increases the suction on the pilot jet so that when you crack the throttle, you have a richer mixture of air and fuel. And this helps acceleration. And this lesser cut-away helps all the way up to around half throttle. And yes, you can feel the difference. You may have to lower the needle one slot to prevent an over rich condition at half throttle. And a word to the wise. Yes, you can overdo this whole idea, and then you will be worse off than before. The throttle cut-away thingie works on both round slide and square slide Mikuni carbs. Even better on square slides....ARH

Ground.
You will avoid many electrical problems by making sure of good grounds. The alternator puts out about 35 volts, AC. The rectifier converts the AC to DC, at a nominal 12 volts. Actually, 13.1 to 14. If that rectifier is not 100% grounded, things like CDI's are trying to handle short spikes of too much AC voltage that they were never designed to deal with. The frames come down the line painted to where the parts are attached. I have previously stated what it is like working on an assembly line. You only have so much time at each station to bolt these parts on. I don't know of an assembly plant anywhere in the world that does not use air operated torque wrenches. Some are magazine fed, but most are not. The theory is that the screw attaching it to the frame will cut through the paint in the hole and make an acceptable ground. I'd say 90 or 95% of the time it works, maybe even more that that. But if you count the number of grounds on your bike, even 1 % means that about 1 in 25 will have problems. Could they ream out the holes to ensure good grounds? On a $1200.00 motorcycle? Get real...ARH

So I took off my hawk's wheels to change tires, noticed that the bearing inner races are almost impossible to turn by hand. Is this normal?

No. Take the bearings to your local store that sells seals (not the ones that Pete wants us to ride), and bearings, or go online and get a name brand. Either Japanese, American or German...ARH

What was Pete recommending? Some how I remember sealed ass bearings or something like that.

Mine were the same way when I first got my bike. When I removed them they spun freely again so I reinstalled them and they worked fine. I do plan on ordering new ones here soon for both front and rear. I just need to get the bearing specs or numbers.

Rear wheel bearings I suspect the spacer tube in the wheel hub is slightly too long and that's why they don't spin (because the assemblers pressed only the outer races when installing the bearings) but I don't know for sure. Last edited by wamey; 07-20-2017 at 11:50 AM. Reason: clarity |
