Theyre 192° exhaust port. Kinda an in between'er but low 190's is what we've had good personal experience with. Its been super hard to keep the website updated or even add cylinder kits to it before they're already sold/spoken for with the parts shortages and the extremely long wait time on plating. Partially why we made a sleeve to install in our casting. All the labor of installing, port match, bore and hone is done in house vs sending them to plating at Millennium for almost 3 months.

I still call bs. Literally hundreds of ppl have bought cylinders from us in a year the exact way you say you didnt. Lane say hes left no email or voice mail unreplied. Good luck with bp racing Sent from my SM-G965U using Tapatalk

state side campsite #511 forsale $125 for the fall bhq ride

if its a stock head that's what the squish is supposed to be … 2 miles. get an aftermarket head with interchangeable domes/combustion chambers.

he'd have to go back in time 6 years to have langcourt plate his cylinders in the usa or send them to the UK where langcourt is.

I did a 421 58x68 and a 424 64x65 this past season. The 421 made 2hp more than the 424. Ported very similar but I would say the 421 had a touch more work.

correct, were not cutting oem heads anymore but we got deez drivelineperformance.com/yamaha-banshee-stealth-head/

definitely, there are not many 424cc cylinders out there to begin with and this ones bad

$425

In the back, down into the rear jackets first, then the flow will come up the 2 side and 2 from jackets and find its way out Sent from my SM-G900V using Tapatalk

never happen, new buyer is a tire kickin mofo

wossner pistons

it took me a over year to sell a set of stockers that I bored to new pistons and cleaned up the porting for $200. The junk ass Chinese cylinders that come with stripped holes, unlevel ports, unchamfered ports, soft ass steel sleeve have ruined the market.

100% there would have been a sticker and instructions.... shops that have bought our lockup in the past are buying the knock offs and still selling them as ours
