...

10 mil serval or driveline low port for the engine with pro mod tranny fireball or lsr long travel a arms fireball +4 or 6 swing arm shock or your choice cpi pipes

Will you be drag racing, woods riding, duning, flat tracking ...etc

Great way of putting it

No. A 421 piston is 68mm so that will be with aftermarket jugs like driveline or CP Industries (cubs and servals for ex). What you do is get a 4 mil crank (longer) and have a builder match the porting to that longer crank and cut domes to account for extra stroke. A set of stock cylinders are good to 66-66.5 mm piston so that puts you around 400cc ish. I would highly recommend you call some builders like the ones that sponsor this page and get quotes then send off your engine. Also, use the search function and read up on some of these builds. Good luck with your build Sent from my iPhone using Tapatalk

And sell your pipes for CPI.

Do a 4 mil stock cylinders build with a dune typ port. Keep stock carbs but add billet bowls, add a shift mod (like a promod), billet clutch basket, driveline head, and hot rod crank. You'll be within your budget and making 75-85 hp.

Entirely depends on how much money you want to spend. So what's the most amount of money you will spend ?

PM me price if still available

Will reed spacers help for clearance? Does anyone here run reed spacers to help clearance issues? yes I know it's one more thing to cause an air leak just curious

I know your still tuning it in, I am real curious to hear how much of a difference the porting has made.

Claude let's see the port work?

Your cylinders were ported therefore lowering your compression.

Your going to want to start big and go smaller. I would start with a 290 main jet. Buy 290 and start leaning out. Buy like 5 sets of jets. Pilot will most likely be 27.5 use youtube for carb sync

try a different cdi. test your stator

great for all around duning. wont slide out when going sideways up a wall

I am currently out of commission and wont be making Brule this year. Join the FB for dune conditions and events. Dont buy those sand gekos on the FB page look further down for the skat traks. There on a 10 in rim but the price is right.

8 paddles on 8-9 in rim. Your from Sask? Look n the AB banshee FB page there is a set of haulers on there and on the Brule Dune FB page there are some dunes tires for a god deal right now. Throw them on the greyhound.

Definitely could be the cdi. So it was running better with the other jet? It might be jetting then. You need to check out how to make a leak down tester and do that first.

What size pilot? Tried moving a clip on your needle? Does it bog when you get off the throttle a little or when you get off the throttle a lot?

My guess is a bad crank seal
