RPM in the 5. gear?

[Fj 1200 wOW]

I am wondering, how high is the rpm at 80 km/h in the 5. gear on Fj 1200 1ty 86 mod? 1500 or 2000 or above? Any ideas?

I feel its time to put in the 18 number front-sprocket- to have more Cruise sound from the engine? It sounds to me that I always have several gears left

But I guess its just I who is not used to the high rpm? But I am sure I read about changing to a larger tanned sprocket will do her more silent.

Good day woW.......on my FJ with 17" rear wheel and 18/38 gearing, 100kph = 3480rpm, 110kph = 3840rpm.

18/38 is the highest gearing I have ever heard of anyone using on an FJ.....you cannot safely use a 19 tooth front sprocket as the chain will not clear the sprocket cover. I've never seen a lower tooth count for the rear wheel.

Hey Harvy!
Mni thanks for your reply to my quest. In fact I wasn't thinking to move above 18. I just wonder may its only a 15 sprocket on mine Fj?

As standard front sprocket on FJ 1200 is 15, so therefore I might changing t o 18 instead, and get a more silent ride?

Stock front sprocket is 17. Much lower and the smaller sprocket will be really hard on the chain. Check out www.gearingcommander.com

Just ran mine 120 miles today. 18 /38 sprockets. 75 mph (indicated on speedo), 3800 RPM. I have 180 rear tire which is a bit shorter. My speedo is a little unstable, pulses about 3 mph...... That's the best i can do until I get the GPS on it.

Pretty much the same for me, I'm set up the same way. Not sure on mileage as I'm doing some final adjustments with lots hard riding and idle time.

Same here.... I have done a few around town trips but today I took her out on the freeway to see how she handles higher speeds and shake down any other problems that might come up. Around town my steering feels neutral and at higher speeds it is a little quick. Not bad just quicker and I notice it more sensitive of course when I put on the front brakes (easy to get a slight "wobble" , sensitive to pressure on the bars). Just for info my rear is up about 1 1/2 inch's and my front end is about 1 1/4 down on the forks. Static rake is at 25.8 degrees and 27.5 with me on it. I figure that with bags and weight on the rear this will trim out. If not I will pull up the front.

The f4i shock works great ! Can't beat it for 75.00.  The front forks I put in 10-30 motor oil and have the settings in the lightest positions and they are working a lot better now. I weigh 216. Incidentally the bike weighed in at 569 LBS with full fuel on the digital bath scales. I think the wife was suspicious when she saw the tire marks on the scale, whoops  

I set the ignition advance up to about 4 degrees and didn't really notice a lot so I bumped it up to 6 to 7 degrees and it seems to like that setting. Running Chevron Premium and no noticeable knocking. I will have to set my idle back down a little. My goal there was the engine running cooler and fuel economy. And yes it feels more snappy. If that makes any since.  I am running 112 mains, needle down to the 4th notch, fuel air screws out 2.5 turns. Altitude 2950 feet.

I got mid point to my test run and while turning around to head back I noticed a knocking sound down around the front sprocket area. That got my attention !! The new chain looked good and I had replaced the sprockets. So I took it easy going home. When I got back I pulled the sprocket cover off and discovered the chain was just nicking the steel plate attached to the sprocket cover. Easy fix...  (hammer and grinder) I was glad of that. The front sprocket is a 18T Honda with a little off set and as the cover gasket was pretty bad I had decided just to leave it off as it serves no purpose that I can see. Hence the chain clipping the steel guard.

The Michlen 180 Pilot Road clear the chain and no noticeable rubbing or milling on the tire. The chain is close but no contact. The rear tire is set dead center and in alignment with the front tire.

Next I guess is to load with the bags and trunk with some weight and she how she handles going on a trip. Today I received my GPS bracket for my handheld unit so I can get a more accurate speed reading.

Testing and shake down continues

Hi George!
Mni tnx for your detailed info. It is vy informative written. So I am appreciated for such experience. I will take the beauty out for a ride one of the first days, now the weather here in north Norway is above plus 10 C.

So I will take a closer look at my front sprocket and count thee-ts. I might change from 15 up to 18 am right, I like it more at 3000 rpm and 250 mp/h. Yeah, I will not stress the clutch too much so going easy. I have been reading on how to make a mode at the clutch unit by increase the spring pressure by adding one extra spring, )

So I will not pay that too much attention yet, by now. Just have it in mind- In case. Its a lot of power to use by firmly careful likes.   She might observe the tire marks,when she feel too heavy?

Well, that's it. I've got no hope now, it's gone viral!

Hi,  FJmonkey, nice link-

I took her out at E6 and tested rpm in 80 Km/h by 5. gear. The rpm was exactly at 3000.

So now I will take off the shield and count the front sprocket teeth. If I can come down to 2500 rpm, at same speed, I am glad.
The trip was vy nice and the sky was clear. And the home made auto-lube system did oil the chain by no regret.
