Bit of a dredge. Got the KX forks on which highlighted how undersprung the back is. So looking for a 5.6 or 5.8 rear spring. Sending the shock off for a rebuild.
But a obvious question, what grade petrol should I be running it on?

What ever it's set up for. Higher octane fuel is more detonation resistant, but that just means you can run more advanced timing and/or higher compression. You won't get any real benefit out of running high octane fuel if the bike has been set up for regular fuel, i.e. isn't ported and running some crazy high compression ratio... certainly no more power from doing so.Originally Posted by nzspokes

50/50 aviation and pump fuel , get 5 thou skimmed from the head , rad/boysen intake , over bored carb, KX ignition etc.

Or quit messing around and just run it on methanol...

Not after more power, just making sure Im not doing damage.

Two strokes are low compression so will run fine on 91. I will only use fresh gas though, any older than two weeks and it goes in the car.
KDX's make great power so looking at suspension is the right thing to do.

Cheers. Thats what i was after. Power no issue. Suspension will be solved this week.
Its my skills and fitness thats rubbish. Working on fitness now.

Talked to a kart racer mate about his, he was of the opinion that too high an octane rating is actually counter productive in 2 smokes, as the relative lack of compression means the fuel won't burn properly and leaves deposits behind. Not sure if that has any merit, but sounds reasonable.

I think ive found the source of my jetting issue. Check check shows my KIPS is sticking shut. Got it moving but after tomorrows trail ride I guess I will need to clean it out. Not sure how easy that is yet but there you go.

Dredge.
Not ridden this in ages and want to sort this jetting once and for all. Its running rich on 155/42. Have been advised to change the Oring under the jet block in the carb which is held down by to security screws. Apparently this can cause richness when it gets old.
Anybody got an idea of the part number of this? Just get the feeling a parts guy is going to look at me blankly when I try to order it.

Please keep us up to date on your carb work. My dad has had a KDX 200SR for a few months now, very low mileage and FMF pipe. Proper little minter. But. It has a noticeable flat spot (to rich) and no end of jetting has resolved it, just moved it. His next attempt is working out the effect of needle profiles.
The bike runs great, a proper wee screamer, he loves it, but after riding a CRM and DT 230 he's determined to get the fueling better.

From what I hear this is a common problem.
Forum whore
get them to fax/email you a print out of the KDX200 carb page, i just looked at the fische and can not see the one you mean either ,
or look up on one of the sites that show the parts catelogue,
Pootler
Apparently its not listed in the parts fiche. Will do some looking tonight. Have some pics of it om my laptop.
