As a Christmas present to myself, I decided it was time to replace my worn out bike with a new one. Where the previous bike used the cheapest kit available from China, the new one uses an improved kit from gasbike.net, the Raw Racer II, as this seemed to be the best value for money at the time. Thus far it seems to be pretty ballsy, top speed is unknown but there's way more torque than the old bike ever had. So anyway, meet Dennis III; (Don't ask about Dennis I, that was an autowheel, it sucked) http://dxzeff.com/trash/d3-full.jpg The engine. This engine has a larger piston than the regular China kits, the cylinder and head are a single piece. Carb is stock (heard too many mixed stories about the upgraded ones and they seem harder to repair if something breaks) but it does use an upgraded air filter, CDI is also an upgraded one, all of these parts come with the kit, usually costing about the same as an entire engine kit anyway, so I think I got my hundred quids worth easily. http://dxzeff.com/trash/d3-motor.jpg The exhaust is mine though, the old engine doesn't really like this one so much and the one I was using proved far too loud, annoying the neighbors more than I'd like so this one seemed like a good middle ground. Note how I found a use for the stock chain tensioner, someone else must surely have done that already. Also note the CNC sprocket adapter, that won't be staying, don't know if I just got a bad one but it didn't fit as well as I'd like, I had to make my own shims but it still keeps coming loose, both around the hub and the sprocket itself regardless of threadlocker, my wheel is ruined. http://dxzeff.com/trash/d3-pipe.jpg That's the pipe I fitted at first, it was nice but I'd rather not fall out with the neighbors. Lost a tiny bit of power by changing it as well as the rather nice noise it made, but oh well. I might have carried the name 'Dennis the Menace to Society' since the autowheel I built, but this was an excessive one that was likely to end in some kind of noise ordinance violation I'd rather not contend with. http://dxzeff.com/trash/d3-oldexhaust.jpg As I never posted a full picture of it, here's the old one, Dennis II, made from the cheapest and cruddiest parts available. By now it's a mash of more than one kit. http://dxzeff.com/trash/dennis2.jpg Not sure what to say really, at some point I'll strip the old engine down to try and find that mysterious loss of power but I'm waiting on gaskets coming from China as I'd like to keep it running just for fun and the fact it served me far better than I could have hoped. Suppose I could close off with this; Going back with the old bike proved that the road was slippery due to oil, which was mysteriously there for some reason, and I'm sure has nothing to do with someone regularly riding a beat up 2-stroke that leaks oil everywhere on that roundabout. Wasn't hurt, bike wasn't damaged, but I'll be looking into why the clutch didn't disengage, probably need to adjust the cable. Either way, this new one should make pulling the heavy trailer around much more pleasant than before. It's not as nice as some of the builds I've seen around here, that's for sure, but it should do its job well enough for me.
