Hi just joined today as just got another DT 2002 after my last one 33 years a go
-
Hello there!
Welcome to the forum.
That's certainly a long time ago? What DT did you have back then? An mx?
-
@Calum had a DT125 MK1 black stage 3 tuned by slipsteam kent
-
-
new one having a few problems does 65-70 mph in 5th but when you go to 6th nothing happens also only restarts when hot on full throttle mods new front pipe .read switch removed from housing,6in away from Speedo, read block rubber reshaped carb ,restored std has main jet 240, model 3RML-010 Portuguese ? CDI 3RM-30 any suggestions -
@kevb1967 not enough power to pull the gear. Probably need a smaller front sprocket
-
thanks I will check the number of teeth on the front sprocket do you know what is std
-
@kevb1967 welcome, very nice looking DT you have. My French import has the 3rm-30 CDI and I understand that they're one of the best.
-
thanks how high does yours rev to
-
@kevb1967 mine has no clocks and it has the 170 kit but it does have very good top end and revs freely. Also the powervalve is pinned open so after about 6k it sort of comes alive. Is your powervalve working ok?
-
Unfortunately, the 2002 models were heavily restricted. Even with the derestrictions you can still expect problems.
Get yourself an aftermarket CDI and all those problems will go away and it'll fly through the gears.
Looks tidy though!
-
@Calum thanks any links to them
-
-
@Calum is a 3rm-20 CDI any good as i see they are not restricted
-
@kevb1967 no it's not restricted but if you have the 3rm-30 that is the best one, only available on the French models from 1999-2002 and apparently quite special and rare. Here's a link to a German website which explains the different CDI's. http://dtpedia.de/mediawiki/index.php/CDI_Steuerteile
I don't think your problem is a restriction problem, only starting on full throttle from hot? Maybe fuelling or maybe compression? Sounds like your bike is a full power unrestricted french import. -
hi thanks mine seams to be portages' but registered as new 2002 in the uk ,its a 3rml-010 and 4bl engine stamp, 3rm-30 cdi ,goes like a rocket to 70mph in 5th, but wont pull hard and or enter the power band in 6th gear and only revs to 9000 but not in 6th ,16/57 gearing refurbished carb std 140 main jet, read switch removed away from Speedo, snorkel removed from air box, read block rubber reshaped big one exhaust any ideas anyone .so near but so far some one musts know ?
-
@kevb1967 I mean, it's a 125.doing 70 like that. Could just be gearing.
-
16/57 gearing is this std ? should it rev over 9000 revs
-
The 2000-2004 era were notoriously restricted.
Also appreciate that a lot of these bikes were ridden by youngsters weighing 60-70kgs.

r u saying i need to loose weight , am at 12 st 12lb so down hill it would be faster ?
