Some questions for those of you out there with more jetting/two stroke experience than me: when this bike gets warm, when coming down off a rev, the idle sits a few hundred rpm high for a few seconds then falls back to normal. It’s not really a rev hang as it can be revved up and come down at a...

PSA for those living in minnesota, with a couple of extra forms you can get any “off highway motorcycle” legally registered with street legal plates with very little extra work. I went down to the registrars office yesterday and did it in about 20 minutes, no inspection. You need to sign a form...

Nice! Sheet metal is tough stuff. Pretty cool what you’re doing, wish I’d had that chance in high school Sent from my iPhone using DO THE TON

As one of the resident young guys here, I can confidently say my experience with all this pales in comparison to you all, but I’ll throw my $.02 in here anyways. I’m in school for engineering, and I have some good insight into that world through family and friends as well. So much of what we...

Can get LiFePO4 batteries with pretty decent capacity for pretty cheap. Batteryhookup.com has some 35ah for sale right now for like $50 each and they’re only 10lbs or so I wanna say. I think they pull them from medical equipment backup power supplies so you can pretty much guarantee they’re...

Popped the pipe off tonight to see what I could see on the cylinder. From what I could see it’s pretty good, however there is one vertical score mark that was enough to get my attention. It doesn’t look like it’s through the nikasil, but still concerning. Currently, considering the compression...

Do you have any more info on actually encasing those magnets? That was on my list to do before I even picked it up, but most of the info out there about it just says to do it, not actually how. I assume I’ll only be able to fill the voids between the magnets without causing interference...

Glad to see there’s some love for the kdx around here! Maybe this’ll stir some activity up on here for these bikes I was a little apprehensive initially to the air cooled aspect, I really wanted a water pumper kdx, but seems like these c series bikes are really tough and a pretty good chassis...

Well the FZ I got from ex119x is officially gone. And as happy as I am for him to have passed that bike to me, it’s leaving opened a door to a new-to-me bike… a 1987 KDX200. Kinda funny that it’s the same year as the FZ lol. Anyway, I picked up this gem earlier tonight from a local guy. It’s...

Believe it or not, perfectly fine. The seat actually looks really nice, and the rest of the head/combustion chamber and piston crown too. It almost looks like corrosion to me Sent from my iPhone using DO THE TON

Crank is in, cases are back together, just need to get the piston and get it to a machine shop. I also will be doing the exhaust valve as it’s a mess, as well as the rocker and rocker pivot pin on the exhaust side, as they’re pretty bad. This engine is is worse shape than I’d hoped, I could...

Very nice. Little jealous of you, been wanting an xr/xl 250 for a while now Sent from my iPhone using DO THE TON

How far would you have to trim to make the can section equal length on either side of the mounting clamp(if that makes sense)? I think that would make it look nice and proportional. Either way fantastic work! Sent from my iPhone using DO THE TON

That’s an interesting looking clutch. What’s the benefit of that vs say upgraded friction plates and springs? Sent from my iPhone using DO THE TON

Been working on this bike this week before classes start up again. I swapped the crank over to the 125 unit, and I looked over the transmission and replaced one shift fork. Other than that, nothing else really looked too bad. Someday I would like to build this engine from the ground up, I’d love...
