Definitely gonna want to get the u-bend taken out before you pulley down at all. Then you can go for it, that's why i'd go MPS, because if you have too much KR w/ a 3.4 you can back it off to a 3.5 or start with a 3.5 and pulley down further if you can. That's what i did. It's a lot less hastle w/ a mps hub than a press on.
im looking for a cheap ubend delete now or im gona go have shop make one this week. id like to get a mps but i can get a 3.4" press for $35 unless u know of mps around that price. also i really dont have money to get a kr scanner. do u know if any place will check it or borrow one? thank u.
If you can't afford the hub, i'd say hold off on the modding until you get a little more cash. Trying to do things on the cheap can cause you to cut needed corners and make more headaches than you started with. Not to mention even properly modded you're putting more stress on things and asking for failure. Don't plan to mod unless you plan to rebuild anything you touch. The 3800 is a hearty motor, but don't leave yourself up a creek.
