Effects of changing front pulley & rear tire

AlanH — Thu, 07 May 2009 04:00:00 GMT

This is an old subject that has been hashed around quite a bit in the past and comes up frequently under different topics

Here is some trivia based on mathematical masturbation & known mechanics that might bring more clarity other than what has already been mentioned below:

Improved light to light & rolling burnouts – YES
Reduce top speed – YES
Higher engine RPM when cruising the highway - YES

The speedo & tach will not change at all because the modifications are being done downstream of the speed sensor device. A GPS is required to qualify the changes at a specific rpm or mph. If i'm not mistaken the Road* 5th gear 0.75 ratio will indicate a different speed than stock.

There is no increase in horsepower or torque only a shift in movement on the dyno curves.

Keep in mind that deviating from the 32T stock pulley to 31T or 30T puts the belt drive train under more stress because of the increased reduction ratio.

The percentages listed in these 2-charts use the stock components as the BENCH MARK for comparisons

EXAMPLE: my ride has a 240/40 Metzeler on a 18 x 8-1/2" weld-up rim and a 33T frt Road* pulley = 3.56 + 3.03 = 6.59% diff

I purchased a 33 tooth front pully off a 99 1600 Roadstar. Will it just bolt on ?

[/quote]not without having the lip machined off[/quote]The Road* pulley is symetrical out of the box! Remove 1-flange ring that is stitch welded and have the step machined 1/8" (.125") ..... When properly machined the pulley teeth will not be cut as shown here: http://rswarrior.com/forums/p/24977/367714.aspx#367714

How many teeth and what Mfg's front pulley are you using before and after the failures. A smaller frt pulley (32T stock) puts more stress on the belt and that's a fact Edited: Your gallery photos show a Baron pulley (teeth?)

I would agree that the Dayco Panther belt is a very poor quality rubber belt and a piece of $hit that is not suited for the Warrior.

The 1-1/2" wide Gates BDL-PC-130 is definitely stronger than the 1-1/8" counterpart PC-130-118 both being aramid fibers or Kevlar belts!

The GATES-HTD Poly Chain Kevlar belt : 42616 sold by Phats: BDL-PC-130 is being used by 2-members of the site very sucessfully under harsh drag racing conditions w/o failures on modified HP engines. Based on their gallery specs they are both using the Road* 32T Billet Front Pulley

Re: 1.5 inch rear pulley

kmdc... I've done the Road* 33T frt & 70T rear using a 1-1/2" 130T drive belt with a DIY 240 swingarm. Chk my gallery photos and Homepage url if interested.

The Road* 70T rear pulley is offset approx 3/16" off the Warrior stock pulley centerline. The belt is 3/8" wider and the outer edge of the pulley runs closer to the stock swing arm by 3/16" (half the difference [] ). It's very close as has been discussed in other threads and it is necessary to grind the weld bead for the bottom tab of the belt guard.

The OEM Road* 33T frt pulley being wider is also offset by 3/16" either side of center. The Baron 31T pulley i suspect is very similar being that it is made for the Road*. Not having hands on experience with it i can't comment and only speculate!

If i understand you correctly, a 1/8" spacer is being added behind the cushioned hub inner bearing spacer and the inner whl brgs effectively offsetting the hub and pulley? [] What about a new axle?

If that is the case i suspect the 1-1/2" belt will ride against the frt pulley flange very slightly depending on the alignment!

I recently installed the 33T Road* OEM steel pulley on my bike with the 70T Road* 1 1/2" wide pulley, 1 1/2" Panther Belt and 240 Metzler tire

I did 90 miles total at elevated speeds on my way down to Phats to pickup the wide belt and had the 33T frt pulley and stock rear wheel, pulley, belt and new Metzler 130/70HR18 front tire.

Really didn't notice a big difference as i was focusing on the newly mounted tire, frt bearings, rotors etc on the chromed wheel that i had assembled

I now have nearly 900 miles on the completed mod and still haven't got a handle on the mileage or speedo error.

One thing i have noticed is that i'm not looking for that elusive 6th gear any longer  and i'll find myself riding in 4th on the freeway . The changes have affected the light to light performance slightly, but that's not where i'm at 

I'm not the pioneer of this mod but i can say without a shadow of doubt that you need only machine one side of the pulley that faces the case...nada mas...

FACT: the OEM 33T Road* '99~03' frt pulley must be machined to fit our bike

Taken from this post:http://www.rswarrior.com/forums/topic.asp?TOPIC_ID=49007
Here's another topic that i added my .02 :http://www.rswarrior.com/forums/topic.asp?TOPIC_ID=49638

Absolutely....the rear flange is removed and the step should be machined 1/8" to clear the middle shaft case gussets.

The 33T Road* Pulley Flange just touches the Stay Bracket so i removed 1/32" mat'l if that with a Dremel disc
The flange sits behind the stay bracket when assembled to the middle shaft. This course of action isn't required
if you choose to remove the bracket    Stock Road* pulley shown in last photo before machining at bottom

If I get the RStar 33 tooth, part # 4WM-17651-00-00, will it need to be shaved if I am still using the stock pully cover and insert? I searched but the thickness reduction of the pulley seemed to be related to the Yammi pulley case set.

A special thanks to the following members for their help or forum postings that made this a reality:
Kroozn2, RaySDF250, metrickkruzer, Jabo, JoeH, Megawatt, BrazeauRacing, DarkStar and 357Warrior's super human powers to help me remove the front pulley nut that i had torqued to 120 lb~ft many moons ago during my middleshaft replacement []

This project started the 1st of Nov '06' by securing various parts mainly from forum members and Ebay auctions.

The longest lead times were the weld-up wheel and job shop chroming because of the holidays.

Hub Interchangeability

AlanH — Fri, 24 Nov 2006 05:00:00 GMT

In my quest to upgrade to the 1 1/2" Roadstar pulley i discovered that the hubs are the same machined castings.

Only difference is the colors.

The heavier/thicker washer used on the Roadstar is to accommodate the longer stud projection present because of the deeper machined pulley that is required to offset the wider belt on the rear wheel and also for the accessory CHROME PULLEY NUT COVERS that would bottom out because of the longer exposed studs. (THE ASSEMBLED STUDS ARE IDENTICAL FOR BOTH HUBS)
