Hey guys, from my experience I think it will be necessary to change my front sprocket to a 13. I have it but not installed yet. What difference did you see with the front sprocket changed? How does it wheelie? Must be a lot better for trail riding? Reports would be appreciated (before and after).

Thanks!

 

Hey TheFrog,

had my 14t on for about the first 600kms then switched to a 13t, I love the faster response off the mark, but higher revving at faster speeds, yes I can wheelie with the 13t however I'm not very good at it. the 13t is much better in tighter / hilly dirt areas, but if you are doing most of your riding on road, i'd stick with the 14

Cheers
Chris.

 

I should rejet and change my sprocket very soon (looking for some time...). Can't wait to try that 13t. Should be a different bike after that. I don't mind for the higher revs, this is not a street bike but a dirt bike. What I need is a faster throttle response, a bit more torque and power (of what is possible to get from a KLX).

 

Hey chris, do you need the clutch to wheelie with the 13t?

 

just a small bump to get started.. , also when we do our big rides, it is a lot easier to get over all the trail obstacles with the 13.

Cheers
Chris.

 

obstacles...one reason why I tought it would be better.

 

big time, and even then it's nearly impossible. it won't give you more power, just better low-end response, that's it. I'm finding the same scenario with my '09 as my '06 had- tire spin. A lot of traction is lost with the stock tires. I see some 606's in the future.

 

I had 13/42 gearing until a couple months ago..now have 13/45 and love it even more...like u said it's a dirt bike and the bigger rear only adds about another 500rpm to the top speed, just like the 13 did...climbed my first hill today since I put on the new rear sprocket and the bike climbed up the fairly steep hill in 2nd gear no problem at all...love it!!! Also had the bike wide open down a stretch of road and managed 120Km per hour at about 8000 RPM..not bad for a 250...does just what I want it to.

 

With the 13 tooth and 21/18 street tires I can pull 85 at WOT in a tuck. I saw a touch over 90 stock but had a tailwind. I love the low end response with the 13 tooth, its damn quick on the street.

 

I disagree.... its not huge, but you can notice it.... just like alot of mods that i have done from suggestions on here. IMO i feel alot of the mods are made out to be better than they really are, i was disappointed with quite a few of the mods... the biggest gain that i could feel was exhaust. The jetting and gearing were not a huge increase IMO. I ran 13-42 for like 7000 miles, and just switched over to 13-45, and its not even that much more noticable... it does go a little better and i can get the front up easier, but its not huge. just my opinion.
