2009 G-5, stock old school tires 22 front, 24 rear psi, 19 tooth countershaft sprocket, 6,000 miles on the bike, TPS .74, NGK BPR8ES, speeds indicated mph, 10% off from true

calm wind, 50 degrees, erect riding position, 5'7" 155lbs., with bags and rear carrier

Seattle, climbing  I-5 southbound hill from I-405: accelerating through 83 (surprised me when I looked!!), slowed by traffic.

     Northbound I-5 from I-405, ran effortlessly 75-80 (depending on traffic) through rolling hills, hit 85 climbing when possible though slowed by traffic. (downhill doesn't count)

      Climbing 509 hill from 1st Ave. bridge: 75-80, limited by traffic.

On ramp, use 4th gear to 70-73 before shifting to 5th.

Bike feels like it'll run 70-80 all day and like it.

    65-70, vibration negligible.

Jus' sayin'. Don't underestimate this engine

+1, starts to pull a bit weak and work harder when two up but that's what the side roads are for!

[ace.cafe]

Cool.

 Way to ride it  bebopper !

[bebopper]

Also K%N filter. I checked the plug today. Using this page:

http://www.4secondsflat.com/Spark_plug_reading.html

and these pictures:

http://www.4secondsflat.com/plug_chart.html

my plug looked closest to too hot and/or too lean. There was a slight deposit on the ground strap tip which according to the text maybe too much gap, but it's set at .28, came as .30. Also, the slightest hint of chocolate on the resistor side under the ground strap but the resistor was white inside,, and slight sooting on a portion of the thread tip, the rest was just flat black to clean.

Looks like I'll try a 9 and go up @ .2

What is your weight?  Some of us are more (ahem) "settled" in the poundage department.

Are you sure you don't want to go to a 7 on the plug rather than 9?

Weight listed in specs. 9 is colder.

[Alan LaRue]

Was that indicated or actual mph?

I'm about 10 lbs. heavier than you, running a completely stock B5. Had it up to an indicated 88 and it wasn't done yet. (That's how fast the left lane traffic was moving. Completely flat section of I10 (not an overpass, and we don't have hills here!).

[bebopper]

Indicated. You got a good one. My stock G5 was hard pressed to hit 82. Dealers had no answer. Tru speed is 77, 10% error

[P. Schraub]

Hello BeBopper,
       I didn't know a G5 would take a 19 tooth counter shaft sprocket. I have a UCE 2010 G5 Deluxe and went to the 18 tooth. Were there any clearance issues with your 19 tooth ?

[bebopper]

No problem. With the 18 I was always looking for a 6th gear, but the 19 fixed that. With the rest of things I've done, blowing out the oil lines, setting the TPS, I finally have a machine I like. All you need is a 46mm socket, but check the depth. If you do it, use grease without silicon sealer on the gasket. Mine always seeped after dealer silicon, but with just grease, it's clean. Also check to make sure that  the oil hole on the top of the case and cover is clear. Mine was 70% restricted by a silicon plug, so I took the top end apart and blew the oil lines clear. It's simple on this engine, legos. Mine and others I've heard had  clattery top ends but after I did that, the noise disappeared. In the picture, the plug is in the lower hole top center, to the left and below the bolt hole.

[Chiefharlock]

Hmmm... interesting...   This clattery top end stopping after the oil galley was cleared of silicon indicates a definite oil starvation issue.  How much extra wear and tear did you see on you top end components?  How many of us out there have had the clattery top end noise?  Does this seem like a systemic issue, and if so, is this information that needs to be addressed with R-E itself?  Would accelerated wear of components due to this issue be covered for warranty?

Not trying to start a witch hunt or something over this, but hey, $6k isn't just a drop in the bucket for everyone, and as a maintenance manager, I get titchy about stuff like that.  I guess it comes from dealing with military vehicles/equipment  and the various contracts and the like for said equipment.. But anyhow, food for thought.

[bebopper]

   The intake rocker shaft was discolored and there was light scoring on both. The galley was wet so oil was getting through. I was just surprised by the quieter action.

[P. Schraub]

Hello Bebopper,
          Thanks for the info. Looks like I'll go from the 18 tooth to the 19 tooth. I only see the 18 tooth in the RE Catalog. Were did you get your 19 tooth from ? Thanks for the heads' up on the plugged hole.

[bebopper]

  The 19 tooth is the stock C5 sprocket. Also, hears a plug heat range chart:

Good going on your G5.  Enjoy the ride.

Any picture of your spark plug ?

    SinghG5, best I can do.

The 19 tooth is the stock C5 sprocket.

Unless REM changed it in the last few months the stock sprocket on the C5 is a 18 tooth.

     That's not my understanding. The C5 has 18" wheels, the G5 19.

[gashousegorilla]

  18 tooth on the C-5.........That's alright, keep the good info coming...

   Me bad and apologies to all. The stock G5 is a 17, so I switched to an 18. Tire size confusion and old age dementia!!

[t120rbullet]

Hitchcock's sells a 19 and a 20 for the UCE/EFI.
But with a 18 on my G5 I can't see how you could go any bigger without paying a price for it down the road.
CJ

[bebopper]

  I agree. The 18 is as tall as I would want.

[P. Schraub]

Thanks Guys,
       I'd like to hear from someone who has installed a 19 tooth counter sprocket on a EFI G5. I'm very happy with my 18 tooth, but sometimes on the freeway, I wish I had a 19 tooth. I weigh around 160 lbs, so I don't think I'll blow the clutch ! One more time......is there an interference problem with the 19 tooth? I wouldn't think Hitchcocks' would sell it if there was.

[t120rbullet]

Here's a pic of a 18 on a G5.
The sprocket is almost hitting the boss behind the sprocket and the chain has very little room in between it and the case. With some grinding on the boss I think a 19 would fit in there but the chain would be right up to the case on the front side. Any pebble that got a ride up to the front on top of the chain would hole the case. A loose or worn out chain might be rubbing on it also.
Don't see how a 20 would fit in there at all.
I'd stick with a 18 and go up to a 4.00 x 19 tire if I wanted a bit more.

I ran a 20 tooth on my 99 for about 19,000 miles with no ill effects. Went down to a 19 to run it in the Ozarks and kind of miss the 20. It's kinda like a 3 speed with OD.

[ScooterBob]

Drilleth, Tappeth and Grindeth thine Royal Enfield for thy heavenly fit of thine 19 tooth sprocket ..... This seems to be the English way ..... like hanging, haunting, quiet desperation ..... you know, like Roger Waters said ....... 

[GlennF]

The vagaries of something as simple as what front sprocket fits what Enfield are amusing.

The B5 is a case in point, seems to be a C5 engine but a G5 style non O-ring chain. Can you fit a C5 sprocket and O-ring chain to a B5 ? Maybe or maybe not. What difference does the kick start make to sprocket choices ? All very interesting.

Being a fan of big sprockets I managed to get a 26 on my old shovel and a 22 on a Bonnie with the help of my little friend, Dumore. But those old cases had a bunch of meat on em that could be ground away.
That investment cast UCE motor just don't have a lot of extra meat to eat.
I can see maybe getting a 19 in there with some grinding but have major doubts on the 20. At least on the G5.

The sprockets for all of em use 530 chain, O- ring or standard. The width of the O-Ring chain might have some clearance issues with some of the bikes. I think a good quality standard chain (Tsubaki/ DID) is more than adequate for the massive output of all the Enfield models.
Don't know what the B5 uses for sprockets or how big but I doubt REM would change any design for just 1 model.
 

[Alan LaRue]

Instead of going up one in the front, can't we go down one n the rear?

[GlennF]

Bullet rear sprockets can only go bigger not smaller. This is because the sprocket is part of the brake drum and the stock one is as small as you can go.

[Arizoni]

True, and if one wanted to change the rear sprocket and to achieve the same change in ratio as they would get by changing the front sprocket by one tooth they would have to drop the rear sprockets tooth count slightly more than 2 teeth.

[GlennF]

The sprockets for all of em use 530 chain, O- ring or standard. The width of the O-Ring chain might have some clearance issues with some of the bikes.

yeah ... apparently on the old iron bullets all you need to do is fit a spacer between the front sprocket and the engine to make room for an O-ring.

No idea if that trick works on a UCE bike.

[digstuffup]

Just ordered a 19t sprocket for my 2010 c5 from hitchcocks. Will be a while before I get a chance to install it, but I will let everyone know how it goes.

[wokka]

just got back from a trip, 1,160 km, 95% of it highway

My standard 2011 C5 happily sat at 120-130km/h all the way. Topping out (hitting the limiter) at just under 150km/h

[BRADEY]

Wokka.....................what mileage did she return ??

[wokka]

Wokka.....................what mileage did she return ??

To be honest, I wouldn't have a clue.

I know my riding style uses about 15% more than a more conservative rider as we had another C5 on the trip and he was regularly topping up much less than me

Fuel is so cheap here, I never bothered looking at the price and had to look it up.

It works out at US$ 0.46 a litre or 1.75 a gallon
