All of these topics have been well discussed on this board, and the old board. Try the search bar up there (^), and if that doesn't suit you, go to Google and in the search bar type "site:tw200forum.com "your-search-terms""



A few quickhits:

1. If you want an extended swingarm buy one from Japan.

2. There is no more top end.



Welcome to the board.

Use a Yamaha BW 200 triple tree for the front end. It is a bolt in to widen the forks for a rear tire on the front conversion.

http://www.sprocketcalculator.com/ Stock size 14 / 50



Putting on bigger tires is going to suck away some power and resprocketing for more speed is going to lower what torque these bikes already have.



Example changing from a 14/50 to a 15/50 will drop your available torque by 7.1%



If you loose to much torque 5th gear will get pretty gutless if you hit a hill.



All of this would not matter as much with a 350+ cc bike





Most folk around here that go with bigger tires either live somewhere flat or regear for more low end grunt, ride mostly off road and don't care to much about speed.





Some good gearing threads

rich thanks for getting back to me.. i plan on putting two of these on the bike if possible (http://i206.photobucket.com/albums/bb133/grundlelips/motogrip-big__91777_zoom.jpg )

EFX Tires - Moto Grip Radial ATV Tires

im not really too concerned about low end power but would like to gain back any top end if possible from putting two fat tires on it. i plan on extending the swingarm a little sometime this week . but i still want to do some off-roading by me as we have a lot of power line trails that go pretty far.. what do you think i should do as far as sprockets and tires sizes that rear wheel will accept? im on the hunt for a three wheeler front end also

Hmm ... You don't seem to be afraid of a challenge, maybe the dual sprocket setup would work for you. http://tw200forum.com/index.php?/topic/641-the-dual-sprocket-thread/



As Mrgizmow put it

"The advantage of the duel/duel sprocket mod is, you get a "very fast" 6 tooth spread in about as much time as it takes to lossen the rear axle nut. No chain length change is needed if you stay with the six tooth spread (one front, five rear). Of course, you need a wrench and would be inclined to get the rear wheel off the ground so it can be rotated. These issues would be the case with both approaches.



The disadvantage of the duel/duel set-up is it's uniqueness. The second primary sprocket is not held in place by splines on the shaft, it is mated to the stock sprocket and held by two grade 12, 8mm allen bolts and 4 tempered 'coil pins' (very strong). Should you be an aspiring hot-dog Moto-Cross kind of rider, it is anyones guess if bolts and pins will hold. It has worked fine for me for a couple of years."

I've stayed pretty much with stock tire sizes so I can't tell you much about those.



I'm running 14/47 I can nail 75 heading down hills, 65 on level ground, on a mild incline I'm down to 60 and for a decent hill I have to downshift and can just hold 55mph.



I've done the typical rejetting and needle spacing to my 09 carb, I switch back and forth between my stock and fmf pipes. (stock pipe is faster in my case)



I'm 6' and 220lbs



I usually ride logging roads in 2nd

ok thanks.. how does the 14/47 work for you on low end ( example.. rocky hill incline, off road.) does it seem like 1st or second needs to be lower to keep momentum or is it not really that noticable at really low speeds.. becasue i plan on using it off road but also to bomb around town in.. thanks again for your help.. everyone
