[1976 XC500C]

How in the world do I get the starter motor out ? Motor fits like a glove and

when the motor is angled it still will not pull out.

Now that I have the left motor case cover off, any idea's

[Blueing of Exhaust]

Hi, it has been a long while since I have been on but here is my question; My 1983 maxim 400 has blueed exhaust pipes where they hook up to the engine. Could this be because of sticking exhaust valves or timing? I have been thinking of getting a new exhaust but dont want to if they are just going to over-heat. My other question is that between 3k - 4k RPM it hesitates pretty hard going up small hills. Is that normal, or is there a problem with the carbs? Let me know guys. Thanks!

Sounds like a heat problem/very hot exhaust causing the same thing that happens when "tempering" metal.

The second situation maybe related to heat also, I have the same problem on an XS500 after running 5K - 6k,

for over an hour and it being >98 degrees outside. I recently found out that heat from the engine block was transfering

over into the carbs causing gas in the bowls to get very hot (not quit a vapor lock, but getting there) and also

break down of the engine oil viscosity.

You might also look at the spark plugs, they could be "breaking down" at high compression/high load (inclines).

[XS500 oil filter]

Looks like you ran into the same situation I did about a year an half ago. I went through the same search and tries as you. I looked for the

replacement adapter, but there all gone and I finally got tried of looking for the "green grass" over the next hill. I solved my problem by

duplicating the original XS500 oil adapter and changing the metric threads to accept the threads of american oil filters. Of course I had

to make the drawings, present them to the machinist so that we where on the same page, have the threads turned and so on. After brushing

up the two cavities and verifying the flatness of the mounting surfaces and making a gasket, I mounted the new adapter. Works like a champ.

I use the M108 filter and can also use the PH6607 and the STP filter of the same size (the last two filters clear the extanded cover of the

drive sprocket area by a whisker but they fit and thread onto the new adapter without a problem (had I spec'd the thread length 1/8 in shorter a

racing pit crew could change the filter in 2 seconds). Total cost of labor about $325.

I wish you luck finding and trying ready made oil adapters, but for me that was a hard road to travel and I probably sent more in

time trying to find a soluation on the web, but give it a try.
