[@eddiepiecart6030]

Hi mate, Well I just love my Classic 500. I'm 65 and have a lifetime of building high end performance motors here in Australia. I bought a 2009 Classic Bullet 500. My wife and I rode it for about 3 months and I felt that the engine had massive potential to go a lot "harder". We live in the Northern Territory where the speed limit is 130kmh and we have triple trailer road trains that beg to suck you in under the rig. We needed much better performance. I did a lot of research including buying another UCE motor which I tore down and examined and measured to the "nth" degree. I have a nice little workshop with a small lathe and a mill and we made our Bullet a Harley hunter. I know most blokes don't have a workshop, but this is a a bit of a run down on what we have done. These mods will probably be out of the reach of most RE owners BUT someone had to do it. The very first mod we made was to throw the engine pipe to the dump. We replaced it with an 1 3/4" pipe and a Mostyn straight through Megaphone. This increased power incredibly as in extremely noticeable and fuel consumption was way better.. The I went crazy in an engineering way and modified the cylinder head. A serious port and polish job, swirl polished inlet valve and ditch cut exhaust valve. We replaced the throttle body with a 40mm unit and a surprisingly cheap EFI system. Totally tunable too. We installed a crankcase evacuation system which was only $35. No more oil in the air filter box when we caned it a bit hard. We managed to find an individual who ground up some serious cam profiles for us. The performance of the Enfield is not something akin to a very fruity Yammy XY500. If anyone is interested in more information email me at [e-mail]

[@gyanendrasingh4471]

Hi @eddie not sure if you are still around active on youtube, but if you are, is it possible to help out with cam reprofiling. Possible to share the cam profile to which we can grind the stock Cams to, to make them a high lift cam? Any input would be extremely helpful. Thanks

What I like most about these images right now, are the blue skies, dry roads, rich green grass, and leafy green trees. Still winter here, with ice, snow, dirty, wet, slippery roads, nothing green to be seen, and not one leaf on any tree. So it’s very pleasant to see Mr. Fillingham out there motoring along , in summer, of course. Well, summer will happen here soon enough, but there’s encouragement here and a lot of good chat as well. Thanks for all that. Ride on!

[@oldgeezerproductions]

Edited to add: I installed the filter and what a huge difference it made. I bought the Iridium plug, but failed to order a new cap. Carefully ground down the large (soft iron) electrode on the plug and now it fits my existing cap. Easy job and much quicker than sending away for a new cap or even changing caps. My bullet drives like a different bike now with more and smoother torque at low engine speeds. Anything below 2500 RPM was pretty rough before, but now I can (carefully) lug the engine starting at 1800 and it feels smooth. Really helps in the corners when it is inconvenient to downshift. The hesitation, to the point the engine would die or (more commonly) almost die when rapidly coming off idle is now completely gone. I'm a bit mad at myself for not doing these simple and obvious things a couple of years ago. You have made me a believer. My new DNA air filter and my NGK Iridium plug should be here in a couple of days. I hesitated getting a "performance" filter for a long time because I was afraid I might upset the EFI operation, but your engine didn't seem to have any problem. I'm hoping the new plug will help with the sputtering I sometimes get when I open the throttle from idle and perhaps a quicker start.

[@rakesh3967]

All mods big or small makes the bike more yours. That's my personal feeling Sir.

[@samguapo4573]

[@mcbob1967]

These are simple yet nicely effective mods - I've done them on my Classic 500, too. I used a K&N filter, though, since it was a gift and, you know about gifted horses. That's good quality, too - after installing it the Classic goes almost 40km/litre which is fine (before it went 35-36, but I have to say now I am also using 100 octane fuel which reduces consumption, too, and keeps the engine cleaner). The Bullet/Classic is not a thirsty bike per se, bless her, but you're right, tinkering is so good. Anyway. Before installing the Iridium plug I swapped a couple of emails with NGK technical support (very helpful people, I've to say) to double-check something I'd read on the Internet, and yes, they too recommended using a non-resistor cap with the Iridium plug (that, I understand, has a built-in resistor). That was a good chance to install a longer HT lead, too - the original RE lead is, to be honest, on the too short side. Regards and ride safe!

[@CEDARRISE]

I really like your no nonsense, matter-of-fact reviews. Video and sound quality are spot-on too.

[@boomerguy9935]

I agree with you on the air filter elements and iridium spark plugs. I use the same type of both in my cars, trucks and motorcycles. Just out of curiosity, I switched my air-cooled Sportster's spark plugs back to standard and then back again to the iridium plugs on the same day, at the same air temperature for a quick comparison. From a cold start to complete warm-up, the iridium plugs performed better in every way: quicker warm-up and quicker response. This is IN ADDITION TO longer plug life. Another thing I do on my motorcycles is to re-route the crankcase ventilation from going back into the air intake, to going directly out into the atmosphere. Cool and dry air is much better for the engine's health and the motorcycle's performance. In most cases, this is a cheap and easy modification.

[@lisacolbert5987]

Bart has highly recommended your channel a few times.

[@ironcast]

Stuart, I own another mild mannered machine here in the United States. It is a 2003 Harley 883 Sportster. I found magazine dyno tests of before and after installation of Screamin' Eagle air filter kit. Stock the 883 made 44 rear wheel HP. With the kit installed it made 50 HP. I found that completely stunning so that is the first mod I made to the bike. It was a higher hp increase than exhaust for less money, so basically a no brainer. Beside the air filter the kit also includes a new backing plate for the air cleaner assembly. This allows much more air to get to the carb. I bought my kit for $55 from a private owner who had never used it. Then I rejetted the carb with 2 sizes larger main and one size larger low speed jet. I also uncapped the mixture screw and opened it from its original 1/2 turn to 3 full turns. WOW. What a wonderful difference in power that can really be felt, and for so little money.

[@alphatango5668]

I fitted the stage 2 kit from DNA on my Conti. The bike makes a lovely sound now. Saw the same horror stories about oem plugs and switched to Iridium they do make a difference.

On the strength of this video I ordered a DNA air filter for my Bullet C5 EFI. The difference was immediately apparent. The bike feels smoother and seems to have more torque. Nothing more at the top end, although mine does have to lug a chair! It just seemed to be a better ride. Plus the engine sounds even better! Well worth it. (April 2021). Thanks Stuart.

[@SprueMonkey]

Hi! Eine Frage dazu: Braucht man da auch andere Caps oder passen die?

[@peterlamont1533]

Well, I fitted the iridium plug to my Classic 500 'Tribute' and that was an improvement, then I fitted the DNA air filter - too soon yet to tell if that is an improvement. Then I fitted the booster plug, to fool the ECU into detecting a lower temperature than actual, and that was a definite improvement. In that process I realised the stock air temperature plug sits across the air intake so maybe that needs moving. Thanks for the tips!

[@sanjaysanjay-hp2vt]

Me Stuart , I like the way bikes are kept clean and tidy . Maintaining a bullet , one need to be disciplined very much . The English country side and the description about RE was enthralling . I was totally mesmerised. Keep the good job going ………👌👍

[@graemehay5714]

Great video, as ever, Stuart. Plenty of information, clear images and a helpful discussion around the "Myths & Legends" on fitting higher quality items. I ordered an air filter, having followed the link and fitted it last week. I am already running the NGK plug, of course. We can't really ride at the moment because of restrictions but today I had a legitimate errand to run (Pharmacy). The air filter makes an instant difference. As I left home the acceleration in 1st and 2nd gear up to 30 mph was very much better and the throttle required was noticeably less than usual. The bike just breathes so much more easily and on my 4 mile journey it was noticeable throughout the trip. It makes more of a difference , in my view, than exhaust modifications. I had fitted a lighter and less restrictive down pipe and silencer but the noise just got me down. This significant improvement from the air cleaner is important to me because I now no longer believe in louder exhaust pipes: they just seem to annoy non-riders and that does none of us riders any favours. I don't know about the fuel consumption yet of course: I have no doubt from the significant improvement in throttle response that my 90 mpg will improve and just 10% will put me into the three-figure mpg range. Thanks, again.

[@mondo2417]

Hi Stu, thanks for sharing, ive made the same upgrades you have, plus an external temp sensor for the air intake , the sensor now sits underneath the seat, also two stainless anchor rods/bolts (Hitchcocks) that anchors the engine to the frame the the result for my Classic 500 is altogether a more responsive smoother more enjoyable ride, and it will cruise now at 65 to 70mph more comfortably , it does remind me of my early days of riding when i passed my test in 1975 as a despatch rider on an army BSA M20.

[@KevinSmith-jz1nn]

Air and sparks! Good to see classic old school lore seeing the light of day again. Knowledge that was in danger of becoming forgotten as modern bikes have such a huge power reserve over what you actually need for real world riding that there is no need even to consider efficiency gains from such things as air and sparks - unless of course you are going racing. My old Norton Commando benefitted from a K&N filter, and Japanese coils, leads and plugs to replace the Lucas & Champion horrors it came with - not in tangible performance terms but just in terms of confidence it would always get you work in the morning. My Classic 500 hasn't been out of the garage since it was delivered at end of Jan, so I am looking forward to playing when weather and end of lockdown allows. I would be interested to see what you make of Hitchcock's booster plug kit (92120/1) and their Vibration Reduction Plate (92498A) in future videos.

I’m an former bike mechanic, and my former brother in law was a taxi mechanic. Iridium plugs were made purely for longer life due to some modern cars having less than ideal access to the spark plugs. New plugs will always be better. You will immediately feel an improvement. To be honest, when I got my 2010 C500, I swapped the stock plug for an NGK BP5RES. Huge difference in startup, idle and running. The only thing an iridium plug will give is longer life without requiring changing them. There’s no benefit to power and running compared to any other NGK plug. But I will agree, there is definitely an improvement over the stock plug.

[@johnpaul3806]

I was advised to check the filter on the fuel pump when I got my Classic 500. It had done 5000 odd miles. The fuel pump is in the tank and shrouded by a very fine mesh filter. The inside of the tank is coated with a red lead coloured paint, I’m not sure what type of paint it is. This breaks down over time and clogs the filter. I removed mine to find the filter was badly blocked with a sludge the same colour as the paint lining the inside of the tank. Removing it and cleaning it gave a noticeable improvement. The engine was crisper and more responsive.

[@stevemiller6044]

I have had very good luck with Czech made Brisk spark plugs. It is of the multi prong design type--so NEVER A NEED TO GAP IT. I put a pair in my Ural side car rig and it made it go from a no kick start to a one kick start. And as you noticed the cold idle was much improved. I like them so much that I have them for my RE 650 and Himalayan. I have seen tests where several different types of plugs were used in see thru glass head lawn mower engines, and then they ran them with and without load on a generator. There were length of run differences. So measurable results.

I'll believe the air filter and fully synthetic oil are worth doing, but the only reason to use iridium plugs is where you want them to last a long time between changes. Copper core plugs give a better spark in old low compression engines, so just swap for a good make.

I think a new seat should be the first upgrade, that is if your air filter does not need it .

[@glaicogobbo4046]

Completely according to your propositions. There are still the suppressive cables that conduct the energy to the plugs. They are of the resistive type so as not to radiate interference to television sets and currently even for transmission with modern helmets. However, over the years, their resistivity greatly increases, stealing all the energy produced by the ignition system. Another piece that can easily deceive us, if we do not continuously measure its resistivity according to the table in the motorcycle workshop manual, is the pipe which is attached to the plug with rubber insulation on the outside. Many of them have a pre-resistor that sometimes breaks down with little time, producing a thin spark to the plugs. Grateful for the advice. Until!

Hey Uncle Stu.. I've edited this a little here n there as time plods along and I'm modifying things and clocking up more kilometers... My RE C500 is going like a little ripper now.. Apart from updating those idiot lights in the speedo with LEDs, I also replaced the "Tiger Eyes" with LEDs.. I've replaced both the Indian relays in the left cover above the fuses with better ones, fitted a straight through header pipe and added the same muffler as yours (no cats on my bike now, and its gotten a smidge lighter due to three catalytic converters now living in my shed) I decided to ride with the baffle out as it sounds a bit lumpier - it sounds bloody awesome actually.. Fitted a DNA air filter (had to add an extra gasket to that black plastic filter housing as the DNA filter is slightly wider than the OEM one..) Also replaced the OEM plug cap with a resistor cap and have added an iridium plug.. I rerouted the plug lead too.. It was cable tied to the frame directly above the cylinder at a sharp angle.. Some of the copper wires inside the lead were pulled away from the plug cap and didn't get a very good contact, I'm thinking that's what was causing the bike to intermittently cut out while I was riding along.. It doesn't do that at all anymore.. So it was either the plug lead or the relays that were the issue. 🤔 Now the bike accelerates up to 100kph without any drama at all... I think it freaks people out on the freeway, them seeing what looks like a WWII bike pelting along at the same speed as them... Now to see what these mods have done to my fuel economy.. Edit: Fuel economy - not much different - I'm getting 36km/ltr which isn't too bad for a 500cc single... I've replaced the OEM seat with a touring seat so it's a lot more comfy and loosened the nuts on that square bar under the front of the seat.. Now the springs actually work and aren't there for looks.. Some of the shiny things I've covered up.. The petrol cap annoyed me.. I found a plastic cap from a Goulburn Valley fruit container that fits perfectly, and a Berri fruit juice bottle lid that fits the steering head bolt. Also for a bit of "bling" the two bolts that hold the handlebars in place - I've covered with a couple of 12 guage shotgun shells cut right down to the brass... BTW... Before I added those "performance" mods it would take anything up to ten kicks to get it going.. Now it takes just two or three from ice cold.. Brilliant.. 👍👍👍

Hey Sir Galah Ive rad your comment and you have done some mods I did too. Your airintake as well the exhaust is really free flowing now. I have this free flow parts too, but some problems with hasitating of the engine, nevertheless i thought about a powertronic or commander to fix this problem. Do you also intergrated one of those piggy banks? If not, you dont have problems with a lean mixture? Which year is your Classic? Greetings Sam from Sqitzerland

@@samuelbraunwalder3022 My C500 is one of the last produced so its either a 2019 or 2020 - I cant remember.. To get rid of the popping its been suggested to blank off that little pipe that runs off the top of the cylinder.. Upper left side under the tank.. I havent done mine yet but I'm thinking about it.. My bike pops and farts while decelerating.. As far as running lean Im not sure.. Ill check the plug later..

Your DNA ( K&N) Air Filters make the bike breathe free-er; and the Iridium type spark plug supposedly sparks bigger for a more complete burn...That would help performance...

Just subscribed! Sophisticated videos

[@christinedoyle9159]

Brilliant video thank you. I own a Classic 500 2013. I have just changed spark plug and air filter to your recommendations. I have noticed smoother acceleration and tickover. Hitchcocks are now selling both items. I wanted to ask what you were using to seal air filter in. It looks like my red bike grease?

[@allengreen6885]

love the vlogs please keep them coming

[@birbeck87]

Yes another very interesting little video one I will bare in mind when my meteor finally arrives 👍

[@jamesstephen7640]

Hi Stewart Great video by the way after watching bought dna filter plus plug For my bullit 500efi What can I say just brilliant. Jim Stephen

[@davidmawson9071]

Just seen this video, and it is the most informative one I have seen to date. Will consider making the changes, Do you replace the dna filter at all or is it a one fit hit and clean it every so often.

[@rossdarling5975]

Get ready,get ready,get ready.

[@drewlawrence696]

Why aren't you presenting a bike programme on TV ? Someone, somewhere is missing a beat...as in some 12 year old TV executive. Keep it up Stu, new subscriber here, but I really look forward to your videos.

[@davidvardy8582]

As per the norm Stuart informative and to the point. Can you supply info on the compound you used for the sealing/lubrication on the air filter/housing please.

[@denniselenson560]

In my personal experience, the fuel quality is also one of the biggest factors in fuel economy, ease of start, smoothnes of engine run and power delivery. Performance air filters and plugs can be easily made pointless when you're filling from asda.

[@denniselenson560]

Me too, I've noticed I do the most miles for the same £25 whith v-power.

[@terrywootton8882]

Nothing wrong with supermarket fuel.

[@trevorlittle225]

Have you replaced your Classic 350's spark plug with a higher quality one? If so, what? On Hitchcock's site, they have OEM one, Bosch YR7MES which I cannot find any cross reference to say NGK. Someone on internet said it may be made in China by a company called Torch under Bosch brand. Bosch representative from North America knew nothing about the spark plug. I'd say you're absolutely right about RE going really cheap on the spark plug. Thank you.

[@davidcompton8525]

Hi Stu, excellent video as usual. I have my little classic 500 since last summer and did a few mods on her. One being the iridium plug but now I need a proper air filter. I think I will go down the dna route rather than the k&n. Just a quick question. Have you any knowledge of the RE Taurus diesel versions of the bullet ? I ask, because I recently came across one for sale. I've heard of them before and I like them because they're a bit of an old oddity like myself. 40mph pootling about suits me . Any thoughts ?

[@michaelevans1658]

Got a feeling in me water the T120 going to go and a Norton replacement in the future uncle Stu.

[@samueljeppsen9785]

Loce your videos, love that RE-500. It's a classic, regardless of its year.

Best mod of all ... 19T sprocket.
