I'd think so too, you get to squirt a little fuel with a pumper, then start it. I have TM40's on another bike and they're great, still get 42 or so on the road and 30 mpg in the dirt. One TM40 per 575cc cylinder.

Honestly its made me super lazy.

When the bike is cold i'll pull the choke (no squirts), pull in the decomp, clear it out with a few strokes, get the bike so it will kick through with the auto-decomp, kick it through once or twice and it till fire up and purrrrrrrrrrr


Does anyone have any logic about how the auto deomp works? It seems like sometimes mine will only be auto decomp, and then sometimes I go to kick it and its like not there and its full compression? So if i actuate the decomp i can kick it through a time or two and then the auto decomp will work again.

Its been a mystery to me since i've gotten this bike (i'm a two stroke guy at heart, but actually contemplating buying a 4stroke as a dez bike too)

I run the Mikuni HRS 42mm Carburetor it has more circuts and jet in easy, I love it.
the tm40 is for a two stroke but lots of the guys run them. I found it cheaper to get the hrs42 off ebay for $200 and the cables from motion pro $100. or the fcr41 off a crf250 you can get them cheap as well. Bert

Kind of half true. there is a 2 stroke version of the TM40 available that was built for snow machine use. This version of the carb does not have an accelerator pump. But its not the same carb we use for our bikes.

Personally if I was buying another tank, I'd spend the extra for an IMS......I've been that impressed with mine
Does the IMS fit with the spal/ktm fan?

Where did you guys get your TM40? I see Sudco has them. Was the jetting close when you bought it? looks like they are selling for around $500.

Powerbarn -
Good guy, helpful and delivery here in Oz was about as quick as most things are from the USA
He will/should have some benchmark settings by now.
Has had a fair amount of feedback from a number of us re settings/altitude & engine config.
Mine was reasonably close for a stock motor/side cover/exhaust etc.
Moved the needle one clip and changed pilot & airscrew otherwise as good as I can tell.
Starts/runs OK
Plenty info on the Edddy vs TM40 thread

That's awesome. Put a lot of miles on my 650R too and am approaching 10,000 on the KTM that replaced it. Only hope it's half as reliable as the BRP. So far so good. Who else has a high-mileage XR?

The 4.6 gallon IMS fits a Spal 4", the 7g does not.
As an aside, the KTM-fan is a Spal in a shroud.

I have about 40,000 KM on mine. Oil changed every 2000 KM on trips, and valves checked/adjusted every 4000.


I wasn't talking a sumo fender. Those things are just plain ass ugly. I run a CRF450 fender. Takes some trimming in the back area, but in my opinion it looks 100x better then any sumo or stock fender.

I found them for $250 each from amazon, remote choke, main jet was retarded big, but I dropped it about 25 sizes to get it to come off idle...I was gonna lean them out on all the circuits, but it's pretty good with the smaller mains.


Edit; this is the place I got my TM40's, the remote choke model makes it a TM40-6 and the "stock" photos that everybody on amazon is using is of another carb, NOT the TM40-6. You can convert the remote choke to a simple plunger, parts from Sudco on that.

I got these when buying the above item.
