I have an E-Charm 150 EFI and the Ducati brainbox is dead. Won't even turn over without it working, I guess it controls everything. Any option other than spending $600, if I can even find one?

My 54B is a VOG clone, and I got the rear wheel from Scrappydogscooters. I saw that one, not a bad deal just wasn't sure it would fit the same. Thanks for the info, I will order one. |

In restoring a '07 54B I noticed the rear wheel is out of true with a flat spot on it. This won't make for a very smooth ride although I haven't had it out to try it yet. Where, other than the over-priced Roketa website, can I get a wheel that fits?

Remember that the oil can have an insulating effect when it contaminates the cooling jacket so a flush with a mix of 25% to 50% white vinegar with a little Dawn Dishwashing Soap (Very Little) followed by at least 4 flushes with distilled water may be required to get the cooling system closer to 100% effective again. Yes some people should not do their own maintenance at least until after they first learn how to read and comprehend above the third grade level. Hey, it's an engine, not a coffee maker! LOL  |

Crotch rockets are just to compensate for shortcomings in "other" areas  |

Just picked up a Roketa 54b with low miles cheap! Doing an initial look-over I went to check & change all the fluids. Upon opening the coolant tank I saw that it was full but the coolant was very thick, hmm… DOH!!! someone must have thought it was a 2-stroke and filled it full of oil! Yes it got into the system and after a half hour of flushing I think it's clean now. That's almost as bad as when I found gunk in the brake bleeders and realized someone thought they were grease fittings! Always important to grease your brakes...

I just picked up an '07 Roketa 50cc with only 600 mi on it. I got it cheap as the P.O. could not get it running well: hit the gas, back off and it dies sometimes and bogs out at mid throttle. Checked the valves and intake was tight and ex. was loose. Adjusted and still same prob. I took the carb apart and it was pristine inside, it looked new. Sprayed out the jets anyways and just for the heck of it I pulled off the Air Cutoff cover under the throttle linkage just to see if there was a spec of something in there. It was also clean but something didn't look right. I tried to re-assemble it the way it came apart and also looked at the diagram on page 34 of the QMB139 service manual available on this forum (thank-you, by the way) and that showed it going together the way I took it apart.
BUT the drawing, and the way mine was assembled, is WRONG!
The rubber diaphragm goes in first, THEN the spring and then the cover, watching out for the tiny rubber o-ring that I held in place w/ a little grease. The written instructions actually state the proper way to do it but they do not match the picture! Page 38 talks about the accelerator pump service but mistakenly has the picture of the Air Cutoff system. Now it runs great! I'm not sure if the factory got it wrong but it didn't look like anyone has been in the carb. Maybe there's several thousand of these carbs assembled wrong! Worth a look if you can't get it to run right.
