Basically, what do you guys use on your 1040 ?

Hi all, Just figured my chain life is over. Not sure the chain on it (marked 40) was an original, or the right size. From my research here it seems like the following chain is the best one can get to avoid chain troubles. What's the right size for the 1040 bronc ? 40, 35, 420 ? This is a 35...

Thank you @Gdiddy58. But my belt seems symmetrical (if I understand it correctly, both sides of the belt seem to have the same angle).

Hi, this is what I think the original belt on my 1040. From the measurements I've made (I'm not a mechanic), I think that's the belt I need to order to have a spare or two. The center distance between my crank shaft and jackshaft is 7 7/8, the belt is 7/8 at top width. Could someone validate...

Well, I'm happy to report that the bike is now running pretty well, with the original engine and a good idle (although it's kind of eager to go ride when it's still on choke as the engine warms up, as I have to keep the RPM a little high to keep it idling well :p). I was able to find a good...

Ok, so the engine IS due for a rebuild, good to know. I think I cleaned the main jet housing, actually I'm sure I did, but maybe not far enough, I'll have another look. Thanks

Ok, so took the carb out yesterday, here are the pictures. BTW, if this is not the right forum section to ask for advice please let me know and I'll post accordingly. Not sure the carb is still in working order, some corrosion in the main jet socket. I cleaned the best I could with carb...

Hey 45t, thanks for the concern. I actually thought about writing something about not wanting to offend anyone, as I understand the religion of originals ;) And about enjoying the build, I know, I'm more of a computer guy and I'd build a nice gaming rig everyday over actually gaming with it I...

Hi, thank you John for the response. (sick avatar btw lol) I really like your input on the qualification of the engine, to be a "great unit". I always thought that tecumseh engines were good units, but since I found the bronc, I've heard and read some contradictory arguments. I'd way better...

Hi, new comer to the mini bikes world here. I just was fortunate enough to pick up a Super Bronc 2 VT-1040 lately. Played with it a bit and not sure I'll keep the tecumseh (HM100) around for long. Ideally I'd go for a used honda engine, if I can find one, but I heard there are some good...
