hello and welcome to Mike's garage I got
00:00:03.649 00:00:03.659 to tell you I'm a little beat up I went
00:00:05.630 00:00:05.640 and spent three days down in Orange at
00:00:08.750 00:00:08.760 the Born Free show I'm telling you I
00:00:12.290 00:00:12.300 have never ever had more fun it was
00:00:15.200 00:00:15.210 absolutely the best the vendors to the
00:00:18.529 00:00:18.539 people who were there to the motorcycles
00:00:21.109 00:00:21.119 it was just one big wonderful show I'd
00:00:25.519 00:00:25.529 say it was the biggest and best show
00:00:27.380 00:00:27.390 I've ever been to it was awesome I saw a
00:00:30.620 00:00:30.630 lot of people that I've gotten comments
00:00:32.780 00:00:32.790 from on the video channel it was just
00:00:36.080 00:00:36.090 great I can't say enough nice things
00:00:38.389 00:00:38.399 about it I stayed with my friends from
00:00:40.880 00:00:40.890 Lindell breaks thank you you are
00:00:43.459 00:00:43.469 wonderful
00:00:44.299 00:00:44.309 O's that was Paul and his lovely lady
00:00:47.420 00:00:47.430 Jennifer and Chico and I just had a ball
00:00:51.200 00:00:51.210 down there it was great I ran into a lot
00:00:53.270 00:00:53.280 of people I hadn't seen in years and I
00:00:56.000 00:00:56.010 met a lot of people that I hope I know
00:00:58.189 00:00:58.199 for a lot of years to come so that being
00:01:02.119 00:01:02.129 said let's get on to what's for today
00:01:04.090 00:01:04.100 what's for today is my old shovel head
00:01:08.359 00:01:08.369 here is my road bike and being my road
00:01:11.780 00:01:11.790 bike I tried to get a lot of miles out
00:01:14.030 00:01:14.040 of a motor and I have gotten a lot of
00:01:16.850 00:01:16.860 miles out of that motor but one of the
00:01:19.520 00:01:19.530 things with the shovel head his shovel
00:01:21.800 00:01:21.810 heads run hotter than pan heads
00:01:24.080 00:01:24.090 pan heads run hotter than knuckleheads
00:01:27.730 00:01:27.740 so with a knucklehead I've never had an
00:01:30.230 00:01:30.240 oil cooler on it and with a pan head
00:01:32.390 00:01:32.400 I've never had a oil cooler on it
00:01:34.700 00:01:34.710 but I always run an oil cooler on a
00:01:37.280 00:01:37.290 shovel head so when I did this build i
00:01:40.130 00:01:40.140 rummaged through my stuff and i had a
00:01:41.810 00:01:41.820 brand new oil cooler put away some
00:01:44.630 00:01:44.640 customer years ago and ordered it and
00:01:46.730 00:01:46.740 guess it wasn't what he wanted i don't
00:01:48.770 00:01:48.780 remember what the deal was but i had a
00:01:50.389 00:01:50.399 brand new oil cooler so I made up some
00:01:53.630 00:01:53.640 brackets and I mounted it on the frame
00:01:55.460 00:01:55.470 here if you can see it there mark can
00:01:58.130 00:01:58.140 you get it in there and yeah
00:01:59.450 00:01:59.460 and so I mounted it on the down tube on
00:02:02.209 00:02:02.219 the left side because on the right side
00:02:04.219 00:02:04.229 is where I'll be hooking up a side car
00:02:06.230 00:02:06.240 mount so I put it on the left side now
00:02:10.400 00:02:10.410 one of the things with an oil cooler
00:02:12.760 00:02:12.770 is that although it cools the oil and
00:02:16.210 00:02:16.220 helps your motor stay cooler if you only
00:02:19.570 00:02:19.580 run your bike in cold weather and do
00:02:21.940 00:02:21.950 short little blasts the problem is your
00:02:24.940 00:02:24.950 oil doesn't come up to temperature now
00:02:27.550 00:02:27.560 if your oil doesn't come up to normal
00:02:29.650 00:02:29.660 operating temperature what happens is
00:02:32.530 00:02:32.540 all the impurities from fuel and God
00:02:35.050 00:02:35.060 knows what all that form in your system
00:02:38.170 00:02:38.180 are normally cooked out by the heat so
00:02:42.160 00:02:42.170 if it never comes up to operating
00:02:43.900 00:02:43.910 temperature you've got all this junk in
00:02:46.480 00:02:46.490 there and I made that mistake I ran one
00:02:48.400 00:02:48.410 without a bypass valve on it and just
00:02:51.610 00:02:51.620 doing short little runs in the
00:02:53.260 00:02:53.270 wintertime what had happened is the oil
00:02:55.990 00:02:56.000 turned into a miserable chemical
00:02:58.450 00:02:58.460 disaster area so I always run either a
00:03:02.440 00:03:02.450 thermostat or a bypass valve both work
00:03:06.700 00:03:06.710 well I've used both this particular one
00:03:09.820 00:03:09.830 is a bypass valve when it's in this
00:03:12.700 00:03:12.710 direction here the oil is flowing
00:03:15.400 00:03:15.410 through it if I turn the valve then what
00:03:20.800 00:03:20.810 happens is the oil comes up to the valve
00:03:25.890 00:03:25.900 bypasses and goes right back and doesn't
00:03:32.050 00:03:32.060 go through the cooler that way the oil
00:03:34.330 00:03:34.340 gets to come up to operating temperature
00:03:37.380 00:03:37.390 so what I did is I mounted the cooler
00:03:39.970 00:03:39.980 here on the frame and I ran my lines
00:03:42.790 00:03:42.800 where I could basically I wanted him out
00:03:46.180 00:03:46.190 of the way and I don't want him to get
00:03:48.340 00:03:48.350 hurt down below so that's what I did I
00:03:51.340 00:03:51.350 ran them right here down through the
00:03:54.910 00:03:54.920 frame behind the exhaust pipe and I'll
00:03:57.610 00:03:57.620 go over to the other side and show you
00:03:59.350 00:03:59.360 where they end up the oil cooler
00:04:05.100 00:04:05.110 basically runs in series with the return
00:04:09.520 00:04:09.530 line of the engine so what we have is
00:04:15.220 00:04:15.230 two lines coming off the cooler I got my
00:04:18.940 00:04:18.950 old pointer out so that I could actually
00:04:20.590 00:04:20.600 show this stuff and again I ran them
00:04:23.500 00:04:23.510 down the right side
00:04:26.590 00:04:26.600 and one line comes directly from the
00:04:31.930 00:04:31.940 return side of the oil pump you can see
00:04:34.900 00:04:34.910 that in here this is the feed this is
00:04:38.140 00:04:38.150 the return so it's hooked up to the
00:04:40.570 00:04:40.580 return line right over there and goes
00:04:44.740 00:04:44.750 right back down to the cooler and from
00:04:48.220 00:04:48.230 the other side of the cooler it comes
00:04:49.810 00:04:49.820 back and goes up to the oil tank and
00:04:53.580 00:04:53.590 returns again it's the same as the stock
00:04:57.370 00:04:57.380 setup it's just that you've now put a
00:04:59.860 00:04:59.870 cooler in series with it years ago when
00:05:03.790 00:05:03.800 I did it I checked with thermometers and
00:05:05.950 00:05:05.960 I'm not sure everyone believed me and
00:05:08.020 00:05:08.030 I'm not sure I was even that accurate
00:05:11.130 00:05:11.140 but I believe I actually lowered my
00:05:14.530 00:05:14.540 operating temperature in the oil tank
00:05:17.850 00:05:17.860 about 35 degrees now that may be an
00:05:21.910 00:05:21.920 outrageous claim I'm not really sure all
00:05:24.670 00:05:24.680 I know is when I'm running the bike hard
00:05:27.040 00:05:27.050 and I'm running it on the freeway and
00:05:28.810 00:05:28.820 I'm running down the road I can feel the
00:05:31.600 00:05:31.610 difference in the way the motorcycle
00:05:33.430 00:05:33.440 runs it's a much happier motor I don't
00:05:36.010 00:05:36.020 know how else to explain it
00:05:37.450 00:05:37.460 it just seems happier and runs better so
00:05:41.950 00:05:41.960 that being said that's my pitch on oil
00:05:45.040 00:05:45.050 coolers I really believe in them if I
00:05:48.790 00:05:48.800 didn't get to meet you at Born Free I'm
00:05:50.980 00:05:50.990 sorry I got to meet a lot of people
00:05:53.440 00:05:53.450 there and it was fun so for now see you
00:05:59.110 00:05:59.120 out on the road
