I just switched my aer over to ohlins ttx 22 cartridge from coppersmith, it's pretty dang good, I posted on thumpertalk about it, I had the mx tech midvalve setup which helped but was not what I was looking for, the ohlins is a pretty solid product, ... more »

Added reply in a thread 350 vs. 450 5/4/2020 5:52 PM

I have a 350 and it's a really good spread of power, my last 450 felt like it had more overall but was heavy, the 350 I have now is pretty good but wears me out in the sense that it give's me the sensation to rev the piss out of it, they roughly make ... more »

It's not a carb, it's the piece that the main jet threads into, or the piece the needle slides into, I had one on my yz, could not get lean spot jetted out, did seem to rev quicker but other than that for what I do it wasn't to beneficial in my scenario, ... more »

If your super concerned with it maybe send cylinder out to get replated and give them piston to fit it.

I have ran cylinders at .0015 to .002 before, they were fine, that was with forged wiseco, the coating on the skirt is typically a moly, it will wear in alittle, alot of times if I get a cylinder back and it measures on the tight side like .0015 I will ... more »

If I had to do it over again I would not have went the with a 300 cylinder, there is a lot of good tuners out with experience on the yz 250, Tuna is right a stock bore 250 is hard to beat when ported correctly, 300's are flat on top, yes the bottom end ... more »

I have a athena kit on my yz, obviously not a esr 325, but the 300 even with the porting seems pretty flat on top, I feel my stock bore cylinder is every bit as strong and definitely is better mid and up, the 300 is pretty good in the tight stuff.

I've had Derek do work and he did what he said he would, after some tuning they were really good, I've had other builders do work and it was either good or long and drawn out, over the years I've learned to do it myself, whether it's just a rebuild or ... more »

Dont get wrapped up in outright hp or dyno sheets, I would take a bike with less power and a better chassis and suspension then one with the most, dyno's are a great tool but that's where it ends, one might read 45 in California and the next might read ... more »

I would look at resale value on the back half, the suzuki is a good bike, hell there all good bikes, but when your done with it there is a small market to appeal to when it runs on race gas and has a bunch of motor work done, look at longevity, durability ... more »

Flat track bikes make alot typically, but the torque is up there and very linear, I couldn't imagine riding a bike with that kind of power, I'm sure it has its place.
