ok we put a new water pump and seal, changed the oil and put in the right amount blew air through all the lines and it all is fine. he rode it for about thirty minutes and it still bled out just a little bit what could it be? it runs great everything seems to be fine its good oil, bel-ray 85w i am out of ideas, and there is no oil coming out of the silencer either

i have stock crank and carbs in perfect condition the crank is not trued or welded just pulled it out in running order to build my cub make offers

just changed the oil and brand new heavy duty barnett clutch. It also started to overheat along with leaking oil could it be the water pump seal?

What would cause the vent tube to drip oil out of it? my buddy has pro circuit pipes vforce3 reeds k&t coolhead and 35.5mm mikuni carbs. oil just drips if not pours out of his vent hose like half a quart in four hours of riding what the heck is wrong with it?

i have some real good t-6's for sale 300 bucks shipped to your house.

I Just got my 421 cub built and it sounds like that on the stator side it seems to be normal

Should i get small bore shearers or big bore, same with cpi small or big bore for a 4 mil cub with 35mm pwk

I have a set of t-6's that i need to get rid of cause i want some shearers they are in great shape pm me and i can get you some pics, they have blued a little right by the cylinder.

I just built a 421 cub with plus 4 timing 35mm air strykers 150 psi of compression noss coolhead pretty much the works, but i didn't have the money to get pipes like cpi's or shearers or anything so i have my old t-6's. How much am i losing because of these pipes, i will be getting some new ones i am just wondering.

I want to buy some shearer or cpi or grand river racing inframe pipes chrome of course. I have t-6's if anyone is interested in trade or i will buy them outright.

its goint to be hard to weld anything to that flywheel seeing as how its magnetized and even if you do get it to stick it will break off once you put it under very much pressure just spend the money and buy a puller and two or three jaw puller will work ten bucks.

I built a plus 4 to accomodate my 421 cub and it works damn good, it seems to be a happy medium it will still wheelie pretty damn fierce on pavement but i don't ride much of that just to ge to where i am going. i vote plus 4

He is right about the k&n pods wouldn't trade them for any other kind, but to save money you could cut the back of the airbox off where the coolant bottle mounts and just use it like that or what he said and buy the mount.

In my honest opinion spend the money and get you some itp holeshots i have had quite a few sets, they last the best and they have the best traction, if not then get the razr's

I have a 421 cub on race gas with 35mm air strykers plus 4 timing and i need some good pipes for it what would be better cpi or shearers, i don't ride trails much mostly sand washes and open roads and drag racing and hill climbing

I am a little above 5000 feet. i am already running 150 psi and the cylinders are cubs and they are factory with a touch up port.

a 4mm stroker

ok i am already running 110 octane race fuel, i just built my motor and want to run pretty high compression because i am running 110 octane with plus 5 timing how high can i go compression wise with the plus 5 timing?

Get the cub man they are very popular at this point and work can be done to them cheaper due to the higher demand, and i just got my 421 cub together and it rips so i vote the cubs.

Well if you are a good welder or fabricator than yeah it will be a breeze if you just tinker with welding spend the money on either a good swingarm or have it done at a fab shop. What were you going to weld it with as far as how mig tig stick? I have extended quite a few and also buit quite a few and its pretty easy but i am a welder so thats you call like they said your only out ten bucks so give it a whirl. For a shop to do it it will be like 60 bucks an hour so count on being charged 3 hours at least.

what about with +5 timing

how high of a compression can you run with 110 race gas?

I use citgo 110 because thats all i can get in this area its 4.85 a gallon i run it with bel-ray 40-1

Jeff at F.A.S.T gave me an amazing price of 2350 bucks for everything you could think of to do it right cylinders crank and the whole nine yards.

I got my 421 cub broke in and took her out for a spin and holy crap does she haul some as thanks Jeff it runs like a champ and thanks to all you guys for answering my questions.
