If he gets decent starts both motos and stays off the ground top 10. We all know he'll be on a bike that can start top 5. I hope he does well and turn some heads!!

If they really drop 8lbs that's close to having 1 free horsepower. A good start for Honda on the 2022

To make 54 hp with a 250F i would say around 15,500 RPM's or higher. It would take around 18.5 ft lbs of torque at that RPM to put it around 54 HP which is pretty impressive. 22 ft lbs would be the max torque at a lower RPM.

2020 has Yosh exhaust, XPR vortex, recluse torque drive clutch, stock gearing and back fire screen removed made a pretty significant difference. Picks up much sooner on the bottom and revs out hard to the increased 14,600 limiter, can use 3rd in most ... more »

When my bike was stock I didn't feel it was a slow bike but the lack low end torque was noticeable. You had to keep momentum through turns. A re-mapped vortex, Yosh exh. air filter screen delete, good fuel and a Recluse torque drive clutch helped mine ... more »

Reply to Yz125 Cylinder Sleeve 1/20/2021 6:11 PM

Whatever you do, do not sleeve. You will loose a lot of power especially if the ports are pretty far off. I once replaced a sleeved cylinder with a brand new OEM cylinder on a 98 YZ 125 and it was night and day difference on how much stronger the bike ... more »

This started happening to my neighbors 18 yzf450. Picked up the bike used in excellent condition with 5 original hours on it. Bike was solid for about 15-20 motos of practice then just started dying mid moto for no reason but would always start back ... more »

I really like mine, great ergos and handling. Suspension pretty good out the box, turns much better and less busy at speed then the last Gen. What I noticed the most over my 14 is it follows a rutted turn a lot better no knifing or tucking. I put on ... more »

Hell of job, that is one great looking YZ. I agree the plated pipe looks sweet on your bike. The plastic came out awesome. I re did a old RM tank and it took a lot of time and effort to bring it back to life and you did all the plastic. Can't say enough ... more »

No, sorry I forgot to mention the cams, the valves are stock Yamaha. It has mild Jesse Williams cams, nothing radical that takes a lot of spring pressure. I also forgot to mention it was dynoed with a brand new O-ring chain that definitely hurt the power ... more »

Stock to stock about 1-2 more HP through out the curve.

I've built a quite a few 270's, yzf and crf's with help from Derick @ HPbikes. All of these bikes run amazingly well with good reliability. Stock you will notice more bottom and mid with about the same top end maybe a bit more at peak. They don't loose ... more »
