Alot of enduros are registered under power from factory, they can be riden on A2 however if police decide to Dyno you it can cause issues. My mates Beta 300rr came brand new registered at something like 11kw, and I have seen alot of the KTMs are the same. Some insurers ask for proof of restrictions with a2 bikes, most don't. It's on you wether you want to risk it or not, however the likelyhood, atleast in the UK, of being convicted seems fairly slim, I know alot of people riding 600s, KTM 690 unrestricted etc on A2 with no issues, but in the event of a crash you may not be paid out, but the same goes for not declaring modifications. Insurance nowerdays is a nightmare, it's up to you how you want to go about it all.

@Calum yeah last time I ride was only for a few minutes and thanks @Calum @NINJA

+1 on the vacuum kits. I've only just got one and now I'm wondering how I got on for so long without one lol

@Calum thanks for replying,about the cdi restriction,the past owner did derestrict the cdi and it worked fine untill the bike started having problems,also i could definitely feel the difference before the problems when i disconnected the earthed wire so im sure it's not that(i was curious what was the difference),i also checked the wire when it started to have this problem and it looks fine. I will also add that i derestricted the exhaust about a month after i got the bike and the bike still didn't have any problems ,in fact it actually worked much smoother About the electric start issue what should i do,i would know how to bypass the sidestand switch but not the clutch and neutral switch(i don't know where the neutral switch is)

@AndyJay what year dtr you got. Some had auxiliary boost bottles on them. I would get a fuel filter. The tanks are metal, maybe you've got corrosion or some other crap in the tank.
