Reason I asked about trenching and boring is because it is actually needed for the top end and crank to even work. You can still run stock carbs, trans, and exhaust and it will "work" just not correctly. 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. Quote Link to comment Share on other sites More sharing options...

I for see this happening but way worse. 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 Quote Link to comment Share on other sites More sharing options...

You will need your cases to be worked to accept the big crank. You will need an up to date tranny and clutch setup, billet basket and straight cuts, because of the high hp. You will defintly need bigbore pipes and people putting that kind of money in an engine will like to have it ported to their need. So, we are talking some more $$$ here.

Ayesully810 Posted December 12, 2018 Report Share Posted December 12, 2018 (edited) how fast do you REALLY think you are going to go on an mx track? you said you do street riding too? well those two things are completely different, you cant build a bike suited for both. If you are being completely serious and this isnt a joke, Id say build a bike set up for MX like a nice 421 with some sick suspension and arms etc and then just change the gearing if your are going to rip on the streets which id suggest you dont do because its illegal but I get the impression you dont gaf. btw a 392 with toomeys and 34 pjs prolly make in the 70s horse power at best. I bet that if you took a 110 HP 521 on a mx track youd be slower because it would be took much to hang on to. btw top speed on a 521 is 143mph Edited December 12, 2018 by Ayesully810 Quote Link to comment Share on other sites More sharing options...
