Added reply in a thread What is Sunoco's equivalent to VP 4.4 ? 2/27/2020 8:08 AM

compared to U4.4 is ex02 if I remember correctly. Its leaded, high octane, very high oxy content. Its all ethanol based oxygen in the sunoco oxygenated fuels.

T4 is indeed oxygenated. im anywhere from 4-8% richer across the board with it via the FI mapping. Not sure why its touted as a pour in replacement, the stoich is almost as far from pump fuel as u4.4's stoich that comes with a 10% enrichment suggestion ... more »

20 shock is shorter, you could always internally shorten shock thats not a huge issue. I am not sure on ohlins, but I know on previous 18 older works/kit showa shock bodies, the cross over is larger going from body to reservoir and wont quite clear the ... more »

You're making to much sense, and using too much fact. People will still be looking to dump the production 49mm forks off the KX / CRF / RMZ and replacement them with A kit forks from 2010

Bought an 809cc skidoo Mach z triple last week more for the sound than anything. They are dinasours compared to the new DI/PFI two strokes but none the less it’s a blast on flat stuff. I am fairly certain skidoo earns Credits with the etec 2 stroke engine ... more »

Good way to kill the rest of the engine. Over fill it - likely large increase in aeration.

Too long , as in, need to shorten the shaft? Because I just have a body from that era. I used the clevis/shaft/ ect for another shock. An adjustable seal head might get you there.

Cross over from the body to the reservoir - It hits the shock mount. You COULD clearance the mount slightly, its not a load bearing direction IMO. What many are doing (including myself) is just utilizing the A kit shaft /clevis / piston / and teh A kit ... more »

Added reply in a thread Yz250 brake problem? 1/20/2020 6:22 AM

sounds to me like a floating rotor, with worn out rivets. The slop is in the rivets - Caliper grabs disc, however hub (and thus the wheel) can still rotate slightly forward/backwards due to the large rivets having a bunch of slop in them.

Specifically the 2019 CRF450 cylinder is a production works caliper essentially with dual piston sizes. 2019 250F did not have it to my knowledge, and 2018 an older did not have it either. I looked into purchasing one to try rather than a 500$ billet ... more »

Why not buy a set of 19 kx450 forks? Same or better internals than 90% of the a kits for sale. And doesn’t carry the bend over because it was fancy 10 years ago when new price tag.

T4 is unleaded, and the R+M / 2 is lower than that of T2, as it was designed for 4 strokes which generally require much lower octane ratings than the two stroke counter parts with performance work done. The cost is the same between T2 and T4 , so why ... more »

Lemme know how it goes when that shock blows the seal head or bladder cap out with a measly 130 pounds of pressure. This should win vital comment of the day
