@Calum saved Abit of money with the ignitech and I'm really happy with the new software etc to be fair though, and the spark is terrific out the unit!

Jetting a none standard carb on a DT is a ballache, 32mm polini pwk didn't make my DT much faster at all without any supporting mods like ignition etc. The fuel usage was well over double too even with both carbs appropriately jetted.

@Darty yeah seems a difficult one, really don't know where to start with the YPVS at all wiring wise..

Got my DT running and mapped with the ignitech and new DTR engine, sounds really sweet, couple little issues but only one I don't think I can work out how to resolve, how is the YPVS wired into the unit? And by any chance would anyone be able to tell me the cable colours to the terminal number on the Ignitech DCCDIP2? I'm pretty sure it's the four pin servo as it's the later DTRE/X loom and pv. I am pretty lost right now haha. I bought an unwired unit as ignitech never replied to any of my emails, same goes with the support for some reason.. Would like the bike rideable soon but struggling enough for time to get out in the garage at the moment

On DTX SM rims I run 120 front and 150 rear Conti Attack SM tyres, you don't really wanna go much wider than them on standard rims as the profile is pretty agressive, takes alot of lean to get full use of the curve but they feel very good on tight mountain roads.

I'm having success with a Polini PWK 32mm on my DT, runs good with supporting mods but ideally you want to get a programmable ignition if going up to this size of carburetor, as you won't see too much gain. My RE with romeu exhaust, airbox cutout, reads etc ran good with it and had more torque over standard but didn't see an extreme speed difference, however my piston rings were pretty gone and bike was low compression. Original jetting the carb came with was well out and the needle was wrong, took me alot of time and money setting it up to work with the DT, happy to pass on the current good basepoint for it if anyone off here needed it
. Fuel consumption was extreme compared to standard carb too, with +1t on the front on long runs I would average 80mpg with some acceleration and cruising 60-70mph on standard carb with 250 main jet, however I'm guessing around 30mpg currently with the Polini.
Long story short, can't really get much better carburetor than standard without supporting mods ie programmable ignition
I have a pretty much brand new standard carburetor sitting in my shed off an 03 engine, this things done nothing and is a thing of beauty, was tempted to put it on my new engine but going for big power so keeping the Polini. Was gonna keep it as a backup but might be tempted to sell if a good offer came up, none of the bolts have ever been touched or undone, checked mixture screw and it's nice and free. Probably would want bowl and passageways cleaned which I would do but it's just too clean to touch haha.

@Jgb19830 I'm the same, I had access to an entire workshop with milling machines, large lathes etc, just not worth it for the wheels, they're too skinny anyways really.
Good luck anyways

I think I made a post about this, the later ones are the same as an MT 125. I bought the rims off a 2015 and attempted the rear first, spacing for disc and sprocket are well off, you'll need a hubcentric spacer for the sprocket for certain, good luck getting one made, I wouldn't trust using individual spacers and longer bolts. The rear axle is also tiny compared to the DT one, I machined an axle with a step up on one end acting as a spacer and also to allow the caliber bracket to fit on correctly, then I was going to make a step up collar/spacer for the other end. The axle worked and I had the bike rolling but I sacked the project off and bought DTX wheels cheap, there's no real way to mount the wheel correctly and safely without getting expensive components manufactured. The front wheel looked easy enough.
Long story short, sell them on and get some TDR or DTX rims mate.

@Calum apart from later 03+ engines, re etc...
