i have the jd tuner but i havent had a chance to play with it properly but it certainly did make a difference straight out of the box. air box is standard (surely it wouldnt make that much of a difference - would it??) no idea about different ECUs. did they come out with different ones? maybe it is just my ability (or lack there-of)
how would everyone else rate the "power mono-bility" of their 610's? ive done most of the power mods and i still feel a little underwhelmed.
I went one down on the CS (on a SM610 ) goes to 100mph at the rev limiter. I like how it runs this way , more bottom end ....
Lunger, depends on your rear suspension set up too. My rear has a wilburs unit with a stiff spring for my weight. I can lift the wheel in 1st and 2nd, but not 3rd. If your rear is softer your front will lift much easier..
Well that makes sense, I had my suspension worked on and set up for woods riding in New England and that equates to a softer ride.
Been messing with gearing, I've got a 13/46 set up right now and I really like it, but I think I'm going to go with a 14/49 which is about the same, just not as hard on the CS. I ordered a new 114 link RK 520 EXW XW ring to go with it. I have a brand new 112 link D.I.D that fits the 13/46 but the axels way forward in the swing arm. That said, I have a new (3miles) D.I.D o-ring chain (520 -112 link) and a 46 tooth iron man sprocket (4 good rides) that shows no wear if anyone's interested.
I'm on 14/48 and it's too short for rallies. Going to go back to 14/46 - I really find it runs out of puff in a high gear around 5000 revs. Low speed acceleration is awesome, but 14/48 is just too short.
My riding area I never pass 3rd gear. If its still too low, I'll try the 15/49 and see how that works. What ever I don't use or sell will fit the WR 250 I'm going to buy. It's an 02 and the stuff should fit from what I've seen.
112 works with 14/46 and might work with 14/47. I have a 49 rear now, so the 112 isn't going to work. I ran 15/49 yesterday and it was good, but I only did it because my 14 was so chewed up and the new one hasn't come yet.
Iron Man rear and OEM steel front. I've tried a couple of other front sprockets and they get wrecked pretty fast, but the OEM one seem to last and fit better. BTW, I just put the 14/49 combo on with a 114 link chain. The adjustment is pretty far forward, but that's better than 116 adjusted way back.
