@ninja That said, the brakes on the DTR were shit anyway.
Best modification I did to my DT was putting those four pots on.
Seriously, as stupid as it sounds, you're way faster with decent brakes. Can brake later into corners and come out without a sweat.
My rear brake is better than both the brakes on my stock DTRE lol.
@watty I'll check my manual, like I said, DTR's struggle to power the lights, so I doubt it'll power the servo.
Hence why motocross bikes utilise either pneumatic or gearbox operated powervalves.
Firstly you're going to want the check the rating of that stator on those old engines.
They struggle to power the lights, let alone operate the servo, I have a strong suspicion that those wires were a dedicated live and negative for the servo to operate. I doubt the servo will be supplied enough power otherwise.
Don't quote me on that. I'd have to dig through my Haynes manual to know for sure.
I'll be sure to upload the wiring diagrams to this site to make easier for others in the future.
I would recommend getting a battery fitted, the servos tend to be a bit hit and miss without them. I know my DTRE would play up if the fuse went between the battery.
@glynn123 There are better ways to restrict the bike than some plastic box on the inlet tract lol.
I don't know the science behind it, I figured it would work in a similar fashion to the YEIS. But it's as mystery.
The DTRE also had YAIS as well.
@irongamer727 Not to my knowledge, the little box on the side of the air box can also be found on the competition bike WR200, they wouldn't restrict a competition bike. At least that's what @AndyYam told me. And he has a lot of experience with all of that.
Secondly, the PowerJet, to my knowledge (Happy to be corrected) is a clever mechanism to lean the fuel off at wide open throttle, when actually you don't need as much fuel.
The logic is that at WOT, you should be easing off the load of the engine and now it's all about refining that combustible mix. The leaner you can run that engine, the better the burn of combustible mix can be.
The trick is to lean it off as much as possible, without causing detonation.
I've always ran br9eix on my bikes with no isses.
I think that's the one at least.
@scrimsmustang The other thing is, there is no guarantee it wouldn't need work. And then there goes your profit margin.
I've yet to see a rotax engine that hasn't suffered damage...
@scrimsmustang A pipe can make a big difference, especially if the stock system is restricted. Good figures though. I had a mate who had a 1999 KMX and he couldn't keep up with my bog standard DTRE (green and black wire earthed), and I wouldn't call the RE a quick bike.
Odd that it'll do the cleaning cycle fine but not run right.
I'd be more inclined to say faulty CDI more than anything. I guess these bikes are just starting to show their age.
Yeah, it'll be down on performance if that's the case.
Are you sure the other side of the powervalve is fastened properly?
@bradt If there is any play in the swingarm, and you ride it, you risk damaging it further, failure that, the shock.
It will also reek havoc on your wheel bearings as well.
Any suspension component will have consequence, big or small, on many other parts.
If this were me, I'd look to sort that out as a priority.
Just my two pence on the matter.
@irongamer727 Yeah, the valve muffles the exhaust sound, when you pin it, you're blaring the combustion through the expansion chamber.
@thechompster No, just take the two powervalve end caps off. The offside powervalve housing has a bolt to keep the two pieces together, make sure you don't lose the locating dowels as they're prone to falling out. You'll want to lubricate it with WD40.
@dinkydong The lack of privileges is because I don't take commission on you people using my site, instead I merely ask that users contribute to it.
If you want to sell your wares, then you must build up a relationship with the forum, or sell it on GumTree or eBay or BikeTrader.
Sorry it sounds harsh, but if I let you sell your bike on here, then I open the gates up to every man and their dog taking advantage of my good nature.
And that's no disrespect, that's just how it is.
Sorry.
