When you change sprockets you are moving the entire range of your gearing. For example, if you install a smaller rear sprocket, you increase your top speed. But you also increase the speed that 1st gear can go and makes it easier to stall in 1st. Swapping 5th gear makes the gap between 4th and 5th slightly wider and gives you a higher top speed without changing the torque or speed in the other gears. As for the 2nd gear swap, the gap between 1st and 2nd is notoriously big on this bike. What I mean by that is this: If you are in 1st gear, lets say you're revving the rpms relatively high and you're going 12mph and you're riding some trail in the woods. You now want to shift to 2nd and ride at the same or similar speed but at a lower rpm. So you shift to 2nd. Now you're going 15mph and your rpms are super low... if you go any lower you will stall! But you don't want to go 15-20mph. You want to go 12-15mph, but 2nd gear is too tall a gear to do that and 1st is too low! By swapping the 2nd gear on this bike, you bring that gear ratio down and make the shifts from 1st-2nd and 2nd-3rd more even and now you can use 2nd gear on the trail more comfortably WITHOUT changing your sprockets. That means you are getting the result that (most people) want without sacrificing top end speed. I hope this makes sense.

I would say it's a little bit smoother and not quite as snappy as a 250. However, it is much more aggressive and much more snappy than the KTM TPI 300's. I have not tried a KTM 300 TBI yet.

@@MichaelAbramo Thank you for the reply. I currently own the Tm 300Mx 4t, but I keep debating myself if I should sell it and get the 300 2t. I also own a Cr250 250 2t and was curios how the power differs between the 250 and a 300. As I thought the 300 is alot torquier motor and probably even easier to ride it since it's less snappy.

@@JayJay-mt2fc it is way more mellow than your CR, that's for sure. But more snappy than KTM.

@@MichaelAbramo Thank you for all the info. If i go the two stroke route, the choice would between a Tm 300Mx or a Beta 300Rx.

Hello What jetting you fit on this bike?

Glad you gave it a try and that you made it out safely. Consider coming back next year!

You'd definitely enjoy the course. Lots of it is similar to your home trails

If you thought Rattlesnake was rocky come run this one with us. You and dad are welcome to spend the night at my place, twenty miles from the race.

Wow you must have the front end pitched very far forward. Interesting. With 104 sag at the first line, I have a very neutral, maybe slightly high rear end feel.

I absolutely had my clickers too stiff. I forget where they were at (it's written somewhere...) but I agree with you. I came from Michaux Dual Sport right to this race and my settings were totally wrong. I knew RORR would be rockier but also thought "it's still a harescramble!"

@@MichaelAbramo I go soft for most HS races because the course gets so beat up. Even in Jersey except for Sahara.

Its really nice trail. Plus eliminates a potential safety problem.Definitely A level , video makes it look easy

Thanks, funny I've been racing this bike for 4 years and I only just realized this past year how hesitant I am about turning the throttle all the way. It's something I really started focusing on after this race.

I currently have on 15/48. Normally for the woods I run 14/48 but the 15 was fine here. On this lap I was mostly in second and third gear, sometimes fourth, in the woods, and fifth out in the fields. Never first gear. I should have changed to a 14 but I forgot. I wouldn't have had to feather the clutch in third gear so much which makes my hand tired.

This was at about 1pm or so. The track wasn't totally clapped yet, but it was soft and there weren't many berms just yet. Not to mention, the camera cuts through a lot of the dust and smooths things out. Check back in a bit for 2K quality to be available

@@MichaelAbramo yea I couldn’t believe how the track evolved throughout the event. My last lap at 9:30am was probably the funnest one I had

Check back in a little bit - 2k quality will be available

The outer diameters of the gears are the same. It's a non issue. I think in your second point you referenced the description of the video? I fixed the mistake. I don't know why the manual says M2-16T. In any case, you're swapping the 17T to a 16T. It's been a while so my memory of all this is not perfect.

The mechanic the rebuilt my worn counter shaft sprocket spline was not sold but the NV gear works. He said the clicked through the gears several times to make sure it would work. It’s something about the gear cut. Make sure to swap to the 600R drive sprocket. Flip it outside in. Worn countershaft splines mean a complete tear down.

No. Totally different gears. There are no known gear swaps for the XRR.

@@MichaelAbramo ok thanks that what i was thinking since they use different part number. I wish there was a gear swap for them a new 5th would make a world of a difference

You have the correct part number

Hey I remember you. At broad mountain the first (or second, can't remember) and last sections were the most challenging, in my opinion. I didn't finish the event when I attempted 2 years ago. Happy to have at least taken home something last weekend

5th in C250. 19th in overall C. Riding a yz250x.

Added the part numbers to the description. The 5th gear is difficult to source in the US. I actually bought the gear almost 2 years before doing the conversion. Watch ebay because some dude imports them in bulk from europe. They were originally in the NX650 and FMX650.

No head work. Local machine shop for the bore and hone. Honestly I don't need to squeeze power out of this bike. With the right gearing it'll pull 100mph. I just put a high comp piston in to try it out. Reliability is most important to me

Part numbers added to the description. Once you have the countershaft from the XR600, you need an XR600 or XL600 clutch cover, kickstart spindle assembly, and the kick lever.
