Co Springs to 717 jet

Recommended Posts

I almost added this to the other Jetting post but really its a different question... anyways....

I was told that the jetting that I have in my bike right now (jetted for the springs) would be good/close enough for 717 (Divide). I have a YZ250. I would think I would need to re-jet for 717. Anyone have any idea and if so what size is good for 717?

If you're jetted for 6000' at the springs, you'll be a little fat at 9000'. Bike will still run, and shouldn't fould unless there's other factors causing fouling (weak spark, etc)

Bring a jet one size smaller and have a backup plug.

Thanks. That's basically what I was told. I always have a couple of plugs on me so no problem. The guy also told me that my wifes xr100 should run just fine up there so I think we just may make the trip up there this weekend. Now I just have to get some screens put in the since the others one have burnt out. Not sure how I am going to get them into mine though... I'll do a search!

My YZ is jetted for the Springs and runs fine up there also.

No bogging or anything? Just don't want to be stuck on a hill and have to do the tuck and roll manuever. :thumbsup:

if your jetted correctly for the springs cris you should have no problems on 717 or most anywere on the front range. 6 years on my yz and i never fouled a plug up in the hills.
