This is nothing more than failure to properly oil the filter unfortunately. Over the past 20 years, I have rebuilt countless engines from dirt ingestion while using spray on filter oils. I know ill get 500 people that swear they work, but im sure those same 500 people adjust valves every 15 hours. The solution to the problem is good old fashion Bel Ray pour on oil. It is the most effective filter oil at protecting your engine, especially in dry and dusty regions. Living in South Jersey, our summers can be absolutely brutal but sometimes worse than Summer is...

TBF - bikes 30 years ago have more in common with what we are riding today then they did with bikes 10 years prior to them....90's tech (30 years ago) is basically what you see on modern YZ250's, outside the alum frame, which isn't really better or worse. The 80's tech (40 years ago) is quite a bit different and many factory's were still experimenting with sus setup and geometry.

Split lanes take away the racing . You’re on 2 separate tracks , stupid. Then hv markers in the middle , more stupid.

Cmon Deeg's - stick it to the AMA, skip the May 9 SX finale with the title locked up and go race MXGP Great Britain and get your MXDN legs under you.

I don’t like deegan at all….and the rule should be followed and penalties applied…but where the hell was this by the book mentality during the red light/jumping a Red Cross flag??? Where riders actually did gain an advantage, and disadvantage….and no one has asked why the hell are there even track markers before either turn starts. As you saw with Deegan, no advantage was gained. The obvious gain would be changing lanes after the first turn….so wtf were there markers there??? …and before someone says so they have to commit…..I would say….or it would be like the rest of the...

AMA didnt want him beating golden boy jetts 250 record of 5 wins in a row

Seems it hurt Jo and Hammaker more than it hurt Deegan. They both lost an extra 2 points to Davies because of it.

What was the oil level that JBI recommended for you with the spacers? Let us know how you like the ride when you test them out.

I have been studing the JB site for sometime and now I am installing the Volume Spacer the the JBI Pro Perch. The Volume Spacer was a bit of challenge getting to the final location. Had to get out some mini spoons! Will it be benifcial - we shall see! I am venturing that it will be oil level sensitive and since I am under 145 in the kings cloths there will be some testing. The spacer is worth about 40cc to 45cc from what I understand. This setup goes on my 24 YZ144X. If I like it, I will...

Spent last weekend testing the JBI Volume Spacers (VS). FC had my oil at 300cc, so I started there. At my weight (165 lbs with gear) it was too much oil. Had my son ride it (220 lbs with gear, top-level local pro)—same feedback: too much oil. We removed 50cc per leg and rode again. The difference was immediate—the fork now moves through the stroke without the mid-stroke feedback I’ve always felt that “push back” into the bars and upper body and really disliked it. It now settles and tracks. As I understand it, the VS reduces air volume, increasing...

I’m really hoping for a 150 and a 300.

Hmmm - I am unaware of Jeremy McGrath winning the 1996 Supercross championship 30 years ago on a 6" travel POS. I thought his bike was a little better.

Well in context I've been doing my own suspension for like 20+ years and more if you want to count changing fork oil going back to the 80s. So I have most all of the tools needed. It was more difficult than I was anticipating loosening and removing the stock WP reservoir. I've seen a lot of people doing it with strap wrenches but I couldn't budge it even with a ton of heating. I ended up getting the Ktech WP reservoir tool to get it off. The biggest issue on doing any shock is proper bleeding.

Just a note I wanted to add here. I had never heard of JBI suspension before seeing this thread and it caused me to go look at their site and research their parts. I watched a bunch of their videos and I ended up buying and installing their bladder conversion kit on my 24 GG350 shock a few weeks ago. The thing is like a work of art for sure. Need weather to turn here in Ohio to actually get some time on it but I'm sure I'll like it.

My JBI parts are with my suspension guy, awaiting the lower tubes to come back from DLC coating. He has the Ti Pro Perch back in stock and I already received mine. I tried to see if I could move the bendable reeds on the Pro Perch with my fingers and I couldn't at all. Perhaps the internal pressure of a hard landing is enough to bend them. If not, the openings in the perch are so small that I think it would make for a stiff set up. I was also surprised when JB told me to run the...
