@calum nothing is as easy as it seems.

@irongamer727 Well that's tuning for you. You can't expect to modify something and for everything else to just accept it. You need to modify each component separately.
My advice is always, get an aftermarket ignition system. It's the one thing you can buy that will result in decent power gains without any other mods. This is because you are just removing the restrictions placed in by Yamaha. Coupled with a slightly more aggressive ignition (just enough to not cause detonation).
Then when you want a more aggressive map, bump up the carburettor, richen the mixture, and advance the ignition for more power. Throw in a pipe next and adjust the map to suit. Then do the porting last with all the rest of the supporting mods. Perhaps richen the mixture as appropriate and alter the map slightly. That's the order I'd do it in.

Tuning/racing is expensive, and its hard to stop once you start, as everything is connected, just like Calum is explaining.
But its also pretty hard to do right. Some people have spent a fortune without getting anywhere, or ended up with a bike with a 200rpm powerband, or just no low end powerAfter you've removed all the stock restrictions, you have to start spending money. A new aftermarked expantionchamber can really help with the low end, and makes it more ridable when you get in to the gnarly stuff offroad.
I havent seen many weight loss threads, there should be plenty of "meat" to remove from this bike. Lossing 5-10kg from the bike would be great. Removing the clocks and the huge light would help with a lot of weight up high on the bike. Replace it with an enduro light mask and an universal speedometer like trailtech vapor.
Replacing the battery with a capacitor is just about free aswell.Also, servicing or upgrading the suspention is overlooked almost everytime.
Tuning isnt just about getting more hp. Its about making the bike handle better , and making it more rideable aswell.Sorry if that got at little off topic.

@jens-eskildsen Weight is probably one of the better modifications you can do. It's "free", it increases performance everywhere (straight lines, corners etc) and reduces strain on the engine.
For my current build, weight is going to be key, unfortunately the bike is already pretty light and it's the fat sack of shit sitting on it that needs to lose weight LMAO! So I'm on a diet just as my bike is. The difference is totally measurable.
-
@calum i just saw your video of this on youtube this bike is an animal deffinatly stealing some of your ideas although looking at it you have a lot more technical knowledge than me deffinatly the best build ive seen yet
-
@stinkwheeler Ah cheers bud. Well believe it or not, when I started this bike I didn't know a think about mechanics. So all it takes is one project to get up to speed.
It's a good build, but you haven't spent enough time looking at other peoples builds on this forum yet to call it the best
There is a lot of talent on this website, whether it be restoring a classic like @scrimsmustang & @oldman or going all out on the tuning like @Darty & @Louis-James. Definitely worth checking out their builds that they have done! -
@calum I'll second that, and interesting build that is for sure. I've seen you're now building an Aprilia, have you now sold the DT?
-
@2stroke4smoke your joking right? He can’t sell his baby
-
@2stroke4smoke Yeah it's just in a lock up now. Collecting dust. Never even rode it after all that hard work lol.
-
-
@2stroke4smoke I've had it over 8 years now. I've not got the interest in riding it anymore.
-
@calum in that case might you be persuaded to part with your zeeltronic
-
@2stroke4smoke Doubtful. The bike will be used one day. Just not for a few years yet.
-
@calum I've seen alot of the builds on here including the 170 builds ect i should have phrased it differently i should have said one of my favourite builds rather than the best like you said before its all preferance I've had a few dts and hope to own a few more but out of them the supermotos are more my thing and i was planning on the jollymoto tail pipe and alot of those mods that you have done before i read the thread hence why its one of my faves
-
@stinkwheeler Yeah I know mate, I just like to dish out the credit to others. We all draw inspiration from somewhere, it's nice to be referenced for my hard work. Thanks.

Hey let us resurrect a dead thread...
Got the DT out of storage and it runs like turd. Battery is dead.
Bought a lithium battery for it. They are cheap now. £50 and it has 1/4 the weight. It's smaller too. And still packs enough punch to power the starter.
