I have an OP Roller with the GT5 kit....I bought it second hand and it wasn't running, but after a few hours of figuring out what was wrong it's been running like a Swiss watch ....loads of torque w/o much vibrations ....the GT5 fits perfectly in there .....OP roller.
I'm also new to motor bicycling and looking to find a quality motor. I stumbled upon this site (great site btw, learned a lot about MBs here) while browsing for motor kits as I plan to make a board track racer inspired bike. Some stuff i have read says that Grubees are the outright best, and other stuff says that there is no difference between those engines and generic chinese kits. I'm wondering if it would be worth the extra 40 bucks to go ahead and buy a Skyhawk 48cc kit or if i should go with a generic motor as linked below and spend the savings on a better sprocket/spark plug/etc. Does it really make a difference?

I know where to get jet engines that zoom used to carry..i have run 2 skyhawks and a ZB motor(all 66cc).. they have all been fine so far. i have had some things fail. but mostly its stuff that came with the kit, not the motor itself. and you will have that with use anyway.
i can say i would by another ZB motor if i could get one in black. i cant find a place that has them or ships to the USA.. but here is a link to one in standard finish. and its from a solid dealer, cant beat that.

mostly i think people pick china two stroke kits based on two things. 1. legit dealer(warranty and such). and 2. a kit with the things they want such as...motor size, carb, color and things like that. because for the most part they really are the same. people get bunk skyhawks, and they are i think the biggest seller.
just be sure to have a warranty, and the rest is just picking what kit works best for what you need and want. good luck.
Right, before you buy a new Grubee, look at the forum posts about the new CNS carburetor those kits come with. A lot of people are having trouble setting adjusting/tuning them.I think they are the best i wont even bother ever buying another grubee considering the 3 i baught were all crappers.
I told the guy that, but the whole experience left a bad taste in his mouth, and just gave up the whole idea of MBs as a hobby.there are so many carbs that will go on the stock ht intake
