"Contrary to what your nephew says, you should have a working kickstarter since it will start the scooter if the battery goes dead. "
The small gear next to the variator on the crankshaft will make one hell of a racket aswell if you don't put back the entire kick starting mechanism ! I know that first hand . Make sure to line up the markings on the kickstart and cam gears aswell. The kickstart spring is a royal pain in the tuchas to get back to its proper place. I use a bigger wrench end .Just watch out for the fingers. the spring doesn't like them if they get in the way . My 2 cents worth.

Grease or not to grease ? That is the question !
Do I grease the bearings on both my new crankshaft and cam shaft ? Or are they lubed by the engine oil ?

Scrappy did honor the Ebay "buy it now" price last week when I purchased the high performance camshaft he had listed. However I did place a seperate order tho from him for my replacement crankshaft and other needed parts. He did combine shipping and shipped the camshaft with the rest of my parts in the same package(due in monday) .  BillC. |

Thanks Alley ! If I had known about that sooner I would have gone elsewhere ! At least I got a working tracking number. I'll keep the forum posted as things go ! Till the parts come in I can do the majority of the disassembly and partial assembly.Then all I will have to do is assemble the piston ,cylinder and head . I can tear down and get the old crank out and the new one installed with timing chain . time to scoot !

Just a heads up . MXMotorsports Inc. is not recomended by me !! I would seriously recomend you going else where for your parts. I made my order last friday and it just got shipped today (7 days later). I got excuses constantly from them when I inquired by phone and email about why it hadn't been shipped. Those excuses included that they were waiting for the gasket sets to get there for the kit. They say that they ship within 24 to 48 hrs . It took 7 days for them to ship !! When I placed my order I paid for USPS Priority. This afternoon I got an email with a fed ex ground tracking number instead. When I called about that , they said that usps couldn't be tracked (wrong they can!) and that fed ex was better (and more expensive) . Fed Ex carries Priorty packages for the USPS and the packages can be insured that they get there as promised . USPS packages can be tracked if a delivery confirmation slip is attached to them. That way you know it got there ok ! Absolutly !!!!! Donot do business with this company ! Your better off going else where like Scrappydog . Ticked off !  Bill Coleman |

I am replacing my crankshaft so just the nut will be needed from it when I disassemble and remove it. Last night I saw the video and book marked it for future reference.

Just double checking before I order one : 27X1 left hand threading for 157qmj flywheel removal ? What about the starting clutch nut ? That needs to also be removed correct ? where can I find a wrench for that ?

rear break
by: Kaveman - Feb 28, 2011 22:48:13 GMT -6
Post by Kaveman on Feb 28, 2011 22:48:13 GMT -6
spring attached ? Is this a 150 ? Mine ( roketa 150) has a spring before it heads through the rear arm brake attachment on the enginecase . The nut then goes on at the end . The spring is what tensions the end nut to keep it from moving up or down when in use . Adjustment of rearbrake is how far up or back of the final screw end of the brake cable you go.

oy ! Could someone please point me in the right direction. I need a new flanged nut to retain my variator assembly . What is its specs (size and threading) and where can I find the d#$% thing? Is it the same nut that also retains the flywheel ? I checked the 3 engine service manuals I have and none had what I was looking for. Thanks ! Bill C.  |

after looking at my finances this morning I may have to go with a stock 57.8 crankshaft for now. I have to refund a guy asap (from ebay ). I still need a new varitor facplate and nut , gasket set and if possible a a9 cam . I also must get a flywheel puller. The 61cc upgrade will still be an improvement in power than what I have had with just the stock 150cc. That should give me abit more topend correct ?

The +3mm stroker would boot me up to 64cc (if I am correct) . Do you think a 30mm carb would be a better idea than keeping and upjeting my stock carb ? I already know I need a performance tailpipe. After this upgrade with the engine, that is next on the list for me to get.

I picked up a 61cc bolt-on kit on Thursday night for my scoot. I have a " terminally ill" 157QMJ engine on my 05 (MC-27) Roketa and have decided to upgrade it to a bigger bore while I have the chance and cash to do so. What I am still trying to decide is wether to spend the extra cash and go with a +3 stroker crankshaft or stick with a std 57.8 mm . Has anyone done simmilar what I will be doing to mine upgradewise ? Has anyone used the bigbore bolt-on kits in an engine upgrade? I am also thinking of adding a a9 cam to this . Are there any suggestions for upjeting my carb ? My big need right now is more topend . I take country roads at times and the higher speed is needed in some sections. I expect the upper kit ( cylinder upgrade and head assy) to be in by next friday. Im stuck waiting till later next week to order the crankshaft. The 13gr slider weights I got with my mrp variator upgrade I don't like either and will be upgrading to14-15gr ones . This mess unfortunatly started out when I stripped the threads on my crankshaft when I was replacing the variator assembly that was making one hell of a racket . I got the variator nut on wrong (not using a D@#* impact wrench as I should have and not installing the variator assy without the belt). After a couple of attempts at dealing with the issues and stripping out another variator faceplate I made the emergency decision to just upgrade . This would be the best time to do so for me since the engine was going to have to be torn apart and the crank and cylinder replaced. Adding further to the mess I had a vibration within the engine that was also getting worse. That vibration eventually snapped my exhaugst pipe bracket holder 2 weeks back and I had to have it rewelded (luckily at no cost to me) . I am doing my homework and watching and reading anything that will help me with this project. Any advice and help would be much appreciated. Luckily I am a very mechanically inclined person so doing my own work isn't an issue . Ok I've rambled on too much ! Bill C. |
