Default scootwork front pully or 200/70-15 rear tire

Hi guys, i have read many reviews and here on the forum about the scootwork front pully. everyday i ride on the street and always feel like once i pass 50mph i feel the need of a 6th gear.

does it really make it alot better ? I do city ride everyday. rarly go on freeway.

does anyone chaged pully themself ? or i should let professional do it ?
i dont know how to adjust the belt after install bigger pully, or i dont need to?

guess thats the cheapiest way to make it faster and lower RPM at higher speed.

please give me some of your input on this, thanks!!!

pully is not going to make the bike any faster... only way to do that is increase horsepower....pulley will decrease rpm at any true given speed, but it will still run the same rpm as it does now at indicated speed...

yes i know.....i mean when i go about 50 i feel like rpm start to go higher and i always thinking about 6th gear so rpm come down lower. thats what i mean, not really go faster, just want it to go smoother after 50.

or i have heard someone talk about 200/70-15 rear tire....

should i go with bigger rear tire or change pulley ?
saw many bad reviews about SW pulley wear out fast and all kind problem...
the bigger rear tire seem like the way to go and a lot less maintnance.

are you talking indicated speed or actual speed.... because the pulley will lower the rpm vs ACTUAL speed... but will not change rpm vs INDICATED speed .. that is if you are going by the bikes speedo !

they more you talk the more you confuse me......lol

what i mean what i want is when i cruise about 50 or 55 i want it to be less vibration.....i dont really care if it go faster.

everyday i go to work when i cruise about 50 i feel the need of a 6th gear so it gose smoother.

i dont need to go faster. a bigger tire will go faster with the same rpm.....
so if i put a bigger tire and i feel like i ride the same speed, the rpm will be lower and less vibration. correct ? i think so.

So i think i will just have to wait for the rear tire to wear out so i have excuse to buy a new tire or my wife is going to bit%@# at me.

evodog, On this bike the speedometer reads the transmission, not the wheel. Because of this, no matter what pulley or tire or combination you run, the engine rpm will always be the same when your speedometer reads 50mph. If you use a gps to check your speed instead of the speedo, you'll see a change in rpms when you change the pulley or tire size. So:
INDICATED SPEED = Speedometer reading
ACTUAL SPEED = GPS reading

I put the Scootworks front pulley on at the same time I replaced my rear tire with a standard sized Metzler. The combination of a taller tire (the old one was worn out ) and the pulley has helped the top end "need" for 6th gear. You have to remember that the 900 is not a fast bike due to its engine size. For 60-65 ish cruising in a relaxed manner its just plain fun. You will need to have a shop tighten and check the belt unless you have a tensioner. The rear wheel needs to be checked for center tracking as well. You lose a little in acceleration but the top end for a given engine rpm is a little more. I drilled out my pipes and added a Fi2000 and K&N cobra intake all at the same time.

Replaced both Front & Rear pulleys 9-10 months ago. Made a huge difference on the highway cruising at 70+. I would think if you are city riding, just the front will help. The front pulley is the easiest to do (If you have basic skills). I have seen what you have done to your bike and you seem very comfortable working on it. If you want to see what the various changes will do, here is a good website that will calculate any changes in gearing. Speeds are all actual (versus indicated).

Thank!!!! that chart helps a lot. I changed tire to 200/70-15 and look at the chart. the MPH only go up like 2mph, so when i use to ride 50 mph is feel vibrate.
after i change the tire and i should ride at 48 and its low vibration but go about the same MPH.

200/70-15 on 2850 RPM = 50.9MPH
170/70-15 on 2850 RPM = 48.7MPH

so when i get the biger tire if i ride the same speed the vibration would lower down. just a bit.....not a lot.

will i really feel it ? or i will have to change two pulley and rear tire all at the same time to see a big difference.

hum.....what do you guys say ? SW pulley is like hit and miss to everyone.
this bike is my only trasportation and i ride to work everyday.
I can't have it mess-up from the pulley or I'm F-ed.
