Such a cool day yesterday. Went to a mates farm, my son was able to ride in big flat open areas at full throttle for the first time, so awesome for his confidence learning to ride in an environment like that.

Then we did a few trails through tree lined tracks following a river. He loved this, however it was quite a step up in skill level, which he handled it like a champ. By the end of the day his confidence increasing more and more.

We probably overdid it with the ride from the farmers house to the river trail. This was about 2km each way. My son was exhausted on the return leg. Next time I'll shorten this up so it doesn't tire him out as much, lesson learned on my part here, its gotta be fun for the kids otherwise you risk putting them off.

Built a heat shield, after all 3 of my kids got burns from the pipe. Slow learners - but so am I.

I made a plate for the other side, to prevent the riders foot from going into the front sprocket. Probably not really an issue, as the way its tucked away, plus the near impossible chance something could squeeze into the gap between the upper/lower chains - but hey as I've always said "Saftey 3rd"...

I also set the rear suspension up. Google tells me around 25-30mm of bike sag, plus around 100mm of rider sag is about where I want it.

I measured:

As it was when I brought it to be 32/120 which did feel a little droopy?

1st adjustment I made got 22/100 sag numbers, which made it corner like it was on rails...but felt too hard for me after riding it for the past month on the Cadillac suspension settings. It felt like it would bouncy me off when landing my epic jumps (***my jumps are less than 1m high).

2nd attempt I split the difference and ended up at 30/110. This still feels a bit hard and bouncy in the rear compared to the ride I'd become accustomed to...but I figured I get used to it. The bike corners, handles and lands pretty well, it doesn't feel as droopy as it once did. So I'm leaving it like this for now.

I may re-look at this in the future? But keen to just send it for now.

Fancy new grips, stuck on with the old spray paint trick. I had to carefully cut the ends out enough for the bash guards to fit. Looks 1990's cool, which is the period correct look im after.

Added a cheap hour meter, so I can keep track of those services I won't do, then I can feel guilty about not doing them on time...

That bracket for the hour meter was a nightmare to make. I stuffed up by drilling the wrong size holes, but persisted with trying to make it work after realizing what I'd done. Would've been much quicker starting again - but I didn't...FML

On the plus side, it does look tidy now its done.

I was half pie tempted to post a photo of my bigger one, lifting the smaller one, with the vespa on top...

Race numbers for additional horse power. I haven't dyno'd it...but at least 10hp per sticker is my best guess?

So:

That's 30hp engine, plus 3x race number stickers with my name on top @10hp each, total of at least 60hp now!!

Offset risers, to shift bars 30mm forwards and 30mm up. Makes a massive difference, way more of a difference than I ever expected...in a good way too.

My knees don't hit when turning and standing up feels a lot better too. Stoked!!

That's just the stock motor. Its actually not that bad, it moves it along at a nice predictable pace, enough power to have fun with...but definitely not fast in any way.

Years ago I had a YZ125 and it was rated at 37hp...it felt twice as fast as this XR does, so I'm not sure hp is a great measure of how a bike "feels" to ride?

I do like this XR though. Its a solid bike thats such easy-going maintenance wise.

30hp think the xr250r i rode not long ago lost half of those over the decades,but I did just get off a 4fiddy

The xr is one of Hondas most durable reliable bikes so there cool

Thompsons track mission today with a few mates.

Resized_20210522_105434.jpeg.f746eecd6a5f1880293688f2dc0c6814.jpeg

awesome line up of 2 wheeled vehicles.

Us posing for a photo about halfway up. About now we're seriously thinking that the track is so fucked we may not make it to the top, so we'd just pretend we made it.

Another regroup at the actual top. quite an achievement given the current conditions of the track.

heading back down, this photo captures the typical condition of the track. There were much worse sections, where my spirit still remains buried and forever lost to me somewhere in the mud.

It was a great day, but I'm battered and beaten. The XR250R did so well, its a solid bike for sure.
