Alright, there must be a speedo error based on the feedback I am getting.
Agreed, I have only done Phase I mods, but I am happy with the outcome.
But, I am more curious than ever to know the REAL max speed I can hit. I am going to order the Radon speedo from PhiTesla as suggested by Jay. They have a 2 week lead time .

I'm keeping the headlight casket cuz, i believe what you have to replace it with weighs almost just as much! I maybe wrong of course. Even though as much as i want to, the main stand is too practical for me to get rid of. Otherwise everything else is being shed

Got the 18" alloy rims but haven't been able to instal it cuz i can't find a pair of decent matching tires.

Do the K&N, Upgraded carb/rejetting stock carb, and "goldie" exhuast mods.... the results are worth it. You get much more low end torque, and for day to day riding that's the best thing. Get rid of the "hot tube" at the end of the bend pipe.

I've got the Mikuni TM32 on my AVL and there is no clearance issue with the petrol tank and it works just fine.

140 Kmh or 155-160 kmh on an almost stock AVL.... hmmm, I'd say your speedo is wildly optimistic!!!

I checked my speedo with a GPS and above 70kmh the speedo reads a steady 5kmh above GPS. Below 70 its more between 5-8 kmh optimistic. But then I have different profile tires from stock so it may be different from other bikes.

On my AVL I've got a 535cc piston, high lift cams T19 sprocket and other performance mods and even then the fastest i've gone is 141 kmh (GPS). May be if i lie down on the tank I'll get more, but that seems to be it.

For all practical proposes, its not how fast you go, but how you get there. A few basic engine mods and some weight reduction will transform your bike and have you grinning to work every morning (if you ride to work, that is).

@ Cougar: The pic of the bullet with "Nomad" on the front plate, do you have any info on the petrol tank? You know the owner? Some info would be much appreciated. Thanks.

speedo meter would read different if you fix smaller tyres

[Bluu]

Wow, I wasn't aware that people had so many mods done on their LBs. I'm really excited now! Jay - I'm awaiting a word from you when you are available so we can meet and discuss this!

150-160 with that windshield! WOW! thats some awesome performance da!

are you selling your bike by any chance?

also with a 127.5 jet you dont exactly go faster! arent you running leaner now?

anyways i have learnt from experience that RE speedos (or anything coming out of the RE factory for that matter) arent exactly reliable! my own personal experience has been that with the speedo showing 115 kph, the speedgun was showing 101! ofcourse with a bullet, 100 kph will feel like 150 thanks to the vibrations!

Yes. Once i install the 18" wheels, I'm thinking I'll use the CL500 speedometer since they are using also 18" wheels.

[desideep]

i would recomend you to use the SIGMA cycle computer instead of the CL 500 speedometer. cause the CL500 also has major error

Apart from this, you could look at sigma BC1106. It is a cycle digital speedo that can almost match a speed gun if set up right.

I looked at the features of the Sigma speedo and it looks great. The only concern I have is not being able to install it on the bike for good. It looks like you cannot leave it on the bike because it is so easy to whack it!

I have ordered the Radon since it just replaces the standard speedo and it has all the right features. My question is - does it match the accuracy of the Sigma? Feedback from someone that used it would be great.

Well, I will give you a better max speed after I get the Radon, but I can tell you that more than anything, I feel comfortable, balanced and feels smooth with relatively low vibrations. I remember that when I just got the bike, I felt uneasy taking turns and balance was an issue. Lowering the seat and taking some weight off helped quite a bit. Another thing is the front sprocketing - I felt like I could use another gear even when I was on 5th.. but now the gearing is more suitable to my style of riding (shifting gears at slightly higer rpms).

After interacting with Jay, I realized that he has a 150 jet on his LB and in his earlier post he was refering to my setup being lean. I figured that since my petrol Jeep is recommended at 127.5 having that on the bull should be plenty. I recently changed to a 140 jet and need to test its full impact. Also, I found that I had a 15 pilot jet , and I still can't believe that I had not checked it before. It was leading to popping and so switched to a size 30 pilot jet. I have not achieved carb tuning nirvana yet after these changes. I will try it out this weekend and let you know.

Cougar, trust me, you don't want to pay what I have spent on the bike! he he, even I won't buy it from me. Seriously, the bike is a keeper.. I have not ridden other RE's, but I can tell you I have achieved the sweet spot on this one and hesitate to make any more perf mods, lest I mess something up! But, I am getting one of the oil cooler kits which will only help in running cooler.

But, that's true whether you have a windshield or not, since your upper body is providing the same (or worse) air resistance. My belief is that the windshield improves aerodynamics.

@GB - Where did you source the 19T from? My riding style seems to be similar to yours, I too shift at relatively higher speeds. I dont think I need anymore convincing, I am going for it.

I would agree that the windshield would actually improve aerodynamics. The rider's body would act like a sail IMO. However, it does not have to be really tall, a smaller one would be good enough to deflect the air over the rider's head. Hopefully that should address the issue of the windshield acting like a sail in crosswinds. Where did you get yours? Do they come in various sizes? I am interested. I dont think merely reducing the weight is going to work wonders, the aerodynamics are probably more important.

Thanks

Battery is in the stock location, held by a simple old style battery clamp with no box.
Dint relocate the battery to the front of rear mudguard since space there is taken by two HT coils for a twin-spark setup.

Please double check the stock sprocket on your vehicle. I am breaking my head to remember what I had and what I changed mine to. I will call the RE Service station to find out what is on the LB500.

I know I just went 1 size up, but I have read online that some people have pushed theirs to 20T or higher. I think going beyond 19T will impact start up torque advesly.

I was lucky to get mine from a regular bullet spares store on JC Road in Bangalore - I can give your their number tomorrow. Alternatively, you can call India's leading distributor of motorcycle parts. Specialists in Royal Enfield spares and accessories. and find out if they have one.

I have the windshield offered by RE, which is not really that great aesthectically. I would have preferred to get a smaller more aerodynamic one, but mounting one from another vehicle may require some creativity.

I am living with the standard windshield from RE because it helps protect my face from dust and bugs. Sometimes, I also take my 5 yr old girl sitting in front of me and it helps keep the wind and dust off her face too.

I just went for a solo ride today for about 130Kms and my new carb settings with a 30 pilot jet and 140 main jet is a Hoot!! I know I got to change my speedo, but about three times I maxed out at full throttle with the needle going beyond 160Km/hr. But in reality, I don't know if it meant only 130 or 140!! In any case, I was basically out pacing everyone except one new swift that I could not catch!

Ganesh,

Stock front sprocket is the 18T one. Raj(Beast_of_Burden) knows Sandhya Automobiles in JC road if that's the bullet store you're talking about.

About your speeds, you'll be pulling 130+ on the kind of jetting you're running. Also, with a 140 main, your revs will shoot up very quickly. And yeah, time to change your speedo if it is maxing out. Interestingly, most 2007 LB500s with a freer flowing intake and exhaust maxed out their speedos. Before buying my LB500 in 2009, I went out for a ride in one of the early LB500s sold in Bangalore. lat out on NICE road, the LB500 speedo was hitting the max speed. In fact, this prompted me to go for the LB500 as it was a mean machine once modded.

Also, now I have a query since you seem to be having great top end performance. Check your TCI module beneath the seat and check which module you're running. Whether it is the two pin or the three pin one. Two pin = 1000 rpm overrev. Three pin = limited to 6200 rpm. I'm saying this because we tested a 2007 LB500, which came with the 3 pin TCI module as stock, with a 2 pin TCI module. The top end changed dramatically. No, we weren't revving higher but the top end response and revvability was a dramatic improvement over the stock 3 pin unit.

Cheers,

Jay

Jay,

Thanks for conforming the 18T. Yes, I got my 19T from Sandhya Automobiles.. the name slipped my mind even though I have been there dozens of times

I will check the TCI module and let you know if it is three or two pin.

@GB - yeah, I already knew it was 18T, so 19T it shall be. Considering there isnt a bike in the RE line up that has 19T sprocket, who manufactures this sprocket?

@Jay - Thanks for bringing up the TCI module, I had forgotten all about this. Mine is a June 2007 model and doesnt rev as freely at the top as you guys suggest. I will post a pic in a day or two, and you can help me determine what my bike has.

All this talk of top speeds is heady stuff, both you guys need to watch yourselves talk rather casually about 130+ top speeds. While a number of riders have reported those speeds even with stock bikes(speedo error notwithstanding), sustaining those speeds even for short periods of time would drastically impact engine reliability.

Raj,

I understand what you say and I completely agree with you. Whenever I do 130+, it is just for a few seconds at that speed. Just to feel that surge and to convince myself that all is well and everything is working like it ideally should.Plus the roads just don't permit such speeds for longer durations. Maintaining such high speeds for extended durations will certainly lead to hugely accelerated engine wear. The LB500 is just not built to sustain such speeds, no doubt about that.

Cheers,

Jay

You can take off the sigma very easily you just have to twist it and it comes off and then you can either carry it around with you in yur pocket or just leave in the tool box..

second yes the Radon would match the accuracy but it comes at price. the price for the sigma is less than 2000
