If quality parts are used, ran in perfect tune, well maintained, and its put together right. you will have a STRONG running engine that will last for years. As stated above the 10mm will have more torque and more hp. The Numbers will vary on who you ask, but all i know is that you WILL ALWAYS WANT MORE POWER! You will get 3 million answeres on what brand of crank to use. So Contact one of the site sponsors and they Will Set you up. I Used FAST Racing and they have been nothing but great to me. hope this helps

IMO> 7 mill crankshaft is the same $$$$ as the 10Mil. So dont build one of those unless you get a great deal on a crankshaft... And i had a 4 mil built and im already wishing i went with the 10.......

I also have a 421 CUB with 39's, v-force 3, 20cc domes and shearer in-frames. If i wanna ride tight, rocky, muddy, trails i do it anyway. its just a hairy ride!!!!!! But i agree with 87sheerips. Stock cylinder, 33's or 35's depending on port work. OH and dont forget about a boost bottle

IMO, ALWAYS start with a leak down test. Then.... get urself a sync tool from FAST. Comes with both adapters, Its cheap and jeffro will get it shipped out asap

well said Matt! But seriously. I would sell the t-rex before you cant get parts anymore. Then pick up a super Serval kit for the red one. You"ll have the best of both worlds!!!!....

I'll take the trans. pm sent

PM sent pm sent !!!

CONGRATS TIM. haha ya you better fab up a titanium crib!

Well just like it says.... I am looking for a frame for a new build. Looking for one from Canada with a clear title...

Just curious as to how often you guys are on here.... I work for an ambulance service and have A LOT of free time to work on my bike and piss around on the computer... I seem to be logged on 4 or 5 times a day. yikes

How many hours are you guys driving to get there?? Its 22 hours for me, was kinda thinking i should show up....

Yup. Talk to the boys @ FAST and they will set you up with some 39's. And if you decide to go bigger in the future, they will work great for just about any application. P.S you WILL go bigger. period.

ok thanks, I didnt think i would need that big of a main. But i was a little worried. It always ran better with the cgl needles anyways....

Loco is runnin a DM on gas....

hahahaha, can i trail ride my cub motor???

Hey guys, never had this setup for winter so im wondering what u think about my jetting... 421 clean up 39 pwk's shearer sb If 2300ft 20cc domes and its about 20'F out BR9ES plugs .024 172 main 52 pilot air screw..... cant remember also running cel needles in the middle clip. I have a set of dhg but not sure which is the richer needle , thanks in advance

Get your hands on a Clymers manual..... you will need it if you wanna enjoy your banshee lol. contact Jeff @ www.farmandsandtoys.com, he will set you up with one.

are you kidding??? something really wrong with your bike........ I ride for a couple hours...... and with 39's!!

Thanks guys, Me and buddy were just watchin some Top Fuelers and i wasnt sure what the difference was.

Well i wasnt sure where this question belongs. What is Nitromethane? is it Alcohol??

I would get whoever does your head porting to polish your boost bottle....

Sounds good, thanks guys
