Good idea.. I'll try that if I can't get the stock part, ta.toratora wrote: ↑Wed Nov 07, 2018 12:23 amThe part of the air box you are talking about is removable. The stock 50 wont run if you remove it. However, if you kit the bike you have to change it. One way is to get the part from the 125 2T bike. I've done this, and somewhere in the DRP thread there is information on it. But if you don't want to get that part you can do what I initially did with my bike.
Remove the plug, and replace it with some radiator hose. You can get some that will snuggly fit the hole in the air box. I then employed a zip tie to keep it in place. It worked quite well, and there might be a photo of it in the DRP thread, but I probably had upgraded the air box by then. I'll hunt around for photos, and update this post if I find them.
I'd already ordered some from a UK supplier before I saw your reply. They claim to be UK made to some half decent standard, we shall see, the fact the packs are 10 jets with no gaps (ie. 95, 96, 97, etc) suggests they have at least a small amount of confidence in their tolerances–most kits I've seen are 95, 100, 105 etc.
Have to pay for the pleasure, but yeah, it was useful to see the fueling, even if overall it was fruitless (until I get more parts to swap about). Long ride on an unhappy bike in the rain/dark to get back though
I read something about it somewhere, but failed to find the right search terms to find the topic again. Wasn't even sure which forum I'd seen it on. The plastic part can be removed/replaced, as I've had mine out (don't ask). It's a bit fiddly to tighten back up if, like me, you can't remove the filler assembly because the captive nuts are insufficiently captive now and spin.toratora wrote: ↑Wed Nov 07, 2018 12:23 amOh yeah the petcock. I've not had this problem myself, but I remember Patrick talking about it on AF1. It seems that some of the tanks were made poorly, and had an issue with that plastic part failing. From what he said there was no way to replace it. But I can't really believe that there wouldn't be a way. Some sort of sealer should do the job. That or pick up a used one. I actually bought a brand new tank with your bike's livery when my bike was run over. I've never used it because it's yellow, and I found removing the gas cap difficult. However, for the same reasons I mentioned to Berkeley you never know when spares will come in handy.
Ok, so I'm just lazytoratora wrote: ↑Thu Nov 08, 2018 11:39 amFor nearly all of the photos I post they are taken with cell phones. Sometimes I will post images made with the bore scope, and very seldomly I'll employ a "real" camera. Sometimes I may get stills from an action camera like a GoPro, or Contour, but for the most part it's all cell phone action.
I was hopeful that they had new stock in, but that part is actually the 50cc version.
