@NINJA I was messing bud.

@declan said in Project SMX:

@NINJA how very dare you!!

Yes, this is getting a little off topic now...

@declan was quite clearly talking about the bike parts.
@NINJA Let me know if you want me to tidy up the thread.

P.S. I was messing about the off topic. But do let me know if you want me to clean up the thread.

I expect these are becoming very hard to locate.

@scrimsmustang Would probably be your best bet for sourcing the appropriate graphics.

@NINJA Yes, it is the same on the Cagivas as well!

Looking clean. Small touches like that make a big difference

@Bluestoesonnose You can get the engine ported and tuned to make more power in the mid range, rather than peak power.

Again, speaking to a tuner will be able to highlight what needs to be done.

I don't know if he's still knocking about, but Mick Abbey might be able to help.

When I spoke to him last, he provided free consultation, then I sent the barrel, powervalve and head off to him to work his magic. But he said it would be pointless without an aftermarket ignition system.

Yeah. The head is where the majority of the power is made. So yes. you can have the head reworked to alter the squishband.

Really you need to speak to a tuner to understand what it is you're after, where you want the power to be made and what ignition setup you're running.

@finnerz89 Used to notice it a lot on my little 50cc Aprilia RS when I was kid coming home from a late night!

The DTRE/X used 210 main jet also.

My RE, with newer electrics, definitely had problems with no battery. YPVS wouldn't operate properly.

@panmil92 Having a faulty battery can cause issues.

@panmil92 I'd be investigating the generator if it were me. At the end of the day, the bike should operate without a battery....

@panmil92 Yes, if the bike is failing to generate enough power, you won't be able to fire the ignition as many times as necessary. This will result in the engine bogging down due to it misfiring.

WOw, that looks superb!

@panmil92 Did you have the cylinder honed? Its not enough to simply through in a setof rings a d a piston on a used bore. The piston rings need to seal on the cylinder walls.

Whilst I doubt thats your problem its worth checking.

Are you getting excessive smoke? That plug looks too oily. I winder if the cranjkshaft seal is starting to weep.

What is the spec of your DT?

Mikuni TM28 flatslide carbs should run a 210 or 240 main jet. The black good dripping from your exhaust is more likely unburnt two stroke oil, and that plug seems to indicate actually you're flooding the engine with 2 stroke. Rather than it being rich or lean.

Unless your engine is modified, I'd suggest return it back to bone stock. Adjusting the oil pump back to factory settings, restore the air snorkel in the air box and go from there.

When tuning, start from a base and only adjust one part at a time. That way you can understand what affect the change is having.

A perfect colour is "Golden Brown". It is very distinct and you will know instantly if it's right from the colour.

But that only checks WOT fueling, not under load up a hill at part throttle. Which is why bone stock DTR's are very good, since Yamaha have worked all this out!

Neutral light runs off a switch inside the gearbox, runs along the selector drum. Oil light is just a float that sits inside the tank.

Nothing worth taking from the 4DL in my opinion. Better off spending the money on your DTR engine.

@Glynn123 Sod doing 30 miles on the DTR lol. Maybe on really nice mornings.
