Trying to decide on a 66cc Kit (try #2)

This is a hard one to call, look for a kit that comes with upgraded hardware, chain, etc. Standard chain will not last on a 66cc engine!

Thats dax, may be worth the extra$.

90% of these motors will benefit from some minor attention given right out of the box, just look a round the forum a bit, you'll be able to get a lot of info just from reading posts

Jet.............RAW, or ( PK) Z80 from boygofast

TiM

Yup, I have never had a problem with any of my BoyGoFast engines, but have had a ton of headaches with engines from grubby Grubee (feh).

Is the carb upgrade for the jet worth it? I'm also looking into buying a bicycle engine kit.

Nope, go with the original carb.

no matter what motor you buy from gasbike.net they will still send you a gt5

Can anyone back up this statement? I plan on ordering a Jet from them.

Swed - order the cheapest 66cc motor they have, they will send you a GT5 at the cheapest price.

i bought the jet 66cc and they sent me a gt5.

My take after trying one Grubee SkyHawk 66 kit...
These China engine kits are loads of fun, but new out of the box they are rough at best. You could get one that is just right, goes together fine and lasts long, or you could get one that is falling apart (or not completely put together in the first place!) The parts are rough, looks like the rough castings haven't been finished completely, stuff might not be tight on a new engine, there's probably gonna be a TON of gunk in the gas tank. You're gonna have to do a lotta fiddling to get it just right in a lot of areas.... That said....
I must say the ride is pretty nice, mine isn't completely broken in yet, or tuned up particularly well but it pulls me good! If you get any of these China engine kits my advise is get to know every part of it! Check every bolt to be sure its tight, wipe away the factory grease and check the nuts underneath (specially the drive sprocket and clutch) and put in nice fresh grease, on everything! LOL Make sure you lube the clutch cable well, clean/lube the clutch pin (often!), check and recheck all the nuts and screws for tightness very often. You might want to carry a pouch with the basic tools to work on the engine just in case something needs attention on a ride far from home.
I have only a short time with this kit and already I am learning about quite a bit about the engine and other parts. My goal is to eventually know the thing inside and out, disassemble/reassemble completely, once that is accomplished I am sure this thing will serve me well. So, not matter what you decide to buy, get to know it, don't assume cause it's new it's right, or tight!

I just got two GT5's from gasbike.net. I ordered the SkyHawk 66CC "2010" kits (not the cheapest), my kits were fresh, dated 04-20-2011. I do know from talking to them that they have a boat load of these GT5 kits on hand, so perhaps they might just send you one for the lowest price? If they were out of stock on the older model you would think they would take it down or mark it out of stock rather than listing the old model cheap and sending the new model? I dunno...
I think the carb was different, muffler didn't have heat shield, not shure what else was different on the older GT5's. Price is right now $149 and $179, might be worth a try to save the $30 bucks, and I bet even if you get last years kit you'll be just as happy with it. They are both indeed GT5's, even if one is older.

I have built a Raw66, a BGF66 and a PK80. The pk and the bgf were crap and didn't last very long. The Raw66 lasted longer but got stolen. I have a GT-5 personally and have never had any major issues with it and I have close to 5000 miles on my engine, and it's modded to shjt. The things your want to replace immediately are:

- engine hardware for metric 12.9 grade or higher
- 410 chain for 415 or #41 chain
- stock carb for RT carb or dellorto
- stock plug for NGK spark plug
