For those of you who have aftermarket valving, Racetech or other, do you find that you are often pretty close on the clicker recommendations? or is it not all that uncommon to be say, 10 more clicks out on shock rebound? I may try and stiffen up the ... more »

Ya why not sometimes its helpful. See what you can find Murph. So it sounds like maybe this is normal. I guess 2 1/2 turns total isnt much range on the 17mm adjuster. Were pretty close everywhere else comparatively speaking. Im 160 to 165 on most days. ... more »

the Devol pc was an adjustable link. They also offer a lowering link that is non adjustable. Here is the Devol Chart. I also run the forks about 5.5mm up in the clamps. seems good. Just recently installed the JBI Pro perches up front and removed .25cc

Specifically talking rear shock here. I'm pretty happy with my setup but I noticed the last time I was out I wanted to soften my low speed compression a bit on the rear and noticed I only had about a 1/2 turn left before I was fully open. Sag running ... more »

ended up being the rubber grommet from ebay messing with the cable. Seems to be running much better now.

I was going to try swapping those 2 as it's the only component I stole from the Ebay carb, tho I don't expect different results. I kept the oem needle and slide(Needle on 3rd position from the top). I figured no harm in keeping the physical top cap and ... more »

Pretty common problem. I have disassembled the carb and cleaned every passage twice with compressed air, let the jets soak over night and still just seems like there is an air leak somewhere or maybe its time for some new jets? I noticed in the OEM carb

28 Hall...Maybe Ill start with dropping 25cc then. I'm a decent B rider maybe not that fast but I know my skill level is just shy of that. I still hit some pretty big jumps and know I can be on the gas when the settings are good. I find it interesting ... more »

Paul would you mind sharing a little more about how to use the 5V reference? Id be interested to know if I come upon the need in the future. Id like to understand more. Appreciate the insight from both you guys.

Paul, I got some fresh gas and dropped in the 48 pilot and surprisingly ran much better. Very minor bog off a hard snap of the throttle running the fuel Screw 1 1/2 turns out. In regards to the reading across the black and yellow, I could never get a ... more »

Pretty simple but the manual is a bit confusing? 1 does the bike need to be running? Pretty sure it does per the manual? 2. How do I physically adjust the tps when the carb is on the bike? You cant get to it, its tucked behind the frame spar? You cant ... more »

Mr Rob I can see why you would say that. It will be a few weeks before they go in. Thats probably what Ill end up doing. Still not sure on if Ill lower the oil height tho.

Seems like everyone gives these things a good review. Going into a 2014 yz250f. Ill have to reach out about the oil qty suggestions but Im within the current range per JBI directions/site.

Added reply in a thread JBI Pro Perch 2.0 whose got experience? 4/8/2021 6:00 AM

Yes I keep seeing that reference, does it come with oil height specs or do you have to ask? Im pretty happy w the fork oil height, was just looking to smooth out front end chatter and smooth out mid to bottom stoke
