I ride a 392. And. It isnt enough For me I. Toomys 34 mm pwk dyno coil ect.. And I fucking rip aroumd everywere but ita not enough for me so thats why I was want g to make it into a 521 . cuz im worried 421 wont be that big of a jump from 392

I dont understand why a 521 isnt good for mx . it's has alot of power and so wben u need it u use it other than that I just don't get why you shouldn't use one and what is the top speed of a 521

I got. Aftermarket oversized radiator.

Please explain to me about how u have to set up the 521 motor to run correctly . I got 34 mm pwk air strikers. Tommy exhaust. I got. Front end widen +2 and i got works shocks in front and got 6 inch extended swing arm.

Just got a quote for 521 motor rebuild for everything for 3700 .il just go with that

Pretty much o I am going to give it a try this next. Spring or so . ok so what is a pro mod tranny

Why u say that

Are u saying 7000 dollars on just parts cost

And what site sponcer do you recommend

I am. Going to do 521 build on my banshee and. I have about 4,000. Budget. I ride trails and mx track and some street. Can anyone help me out on all the parts brands that u recommend or were best place to purchase from and. Best. Prices. But. Still not jepordizimg quality . And do I want a tranny that I can shit without clutch up or down and have 2 threw 6 gear . along with a lock up clutch set up. If I ride mx track . or would I be better off with normal tranny with having to use good old clutch fashion . and what size of carbs should I use to get most power from and whats the best type to use electron or pwk. Really. What im looking for kinda is a complete parts list and best and fastest shipping retailer. And whats the best aftermarket 200 watt stater to buy
