·  What mileage can I expect?

How long is a piece of string? This is very hard to answer as there are many many variables that make up effective mileage.
In short, on a properly tuned and jetted bike you can expect around 40-45mpg, even higher.
On a badly setup bike it can go below 35mpg

·  What is the Stage 1, 2 and 3 modifications to the exhaust system?

Stage 1 involves removing the cone at the end of your exhaust and drilling 8x half inch holes in the end of each pipe
Stage 2 includes Stage 1 but requires the use of a longer drill bit to drill through the next baffle wall, most believe it is more trouble than it is worth
Stage 3 is removing the cone at the end of your exhaust as per stage 1, cutting away the final baffle plate entirely and then ramming a rod up into the baffle to wriggle the baffle back and forth until it comes out of the exhaust.

0 ~ 198lb = 36psi/250kPa
198lb+ = 36psi/250kPa
High-speed riding = 36psi/250kPa
Rear:
0 ~ 198lb = 36psi/250kPa
198lb+ = 40psi/280kPa
High-speed riding = 40psi/280kPa

Road Star Warranty

Question

·  What is the standard warranty?
·  What is the Y.E.S. program?
·  Will changing my airbox or exhaust void my warranty?
·  Can I remove the AIS without affecting my warranty?

Answer
·  What is the standard warranty?

In the U.S. it is 1 year extendable to 4 years with Yamaha’s Y.E.S. program
In Australia it is 2 years with no extension option

[ Back to Top ]

·  What is the Y.E.S. program?

Yamaha Extended Service. The Y.E.S. program is only in the U.S. and allows owners to extend their warranty out to four years

[ Back to Top ]

·  Will changing my airbox or exhaust void my warranty?

Changing your airbox or exhaust, or both will not void your warranty PROVIDING you do it properly and that includes any neccassary rejetting of the carb. If you burn your valves out because you replaced your airbox but didn’t rejet, that will not be covered under warranty.

[ Back to Top ]

·  Can I remove the AIS without affecting my warranty?

Removing the AIS and plugging the holes let in the engine with custom made plugs shouldn’t affect your warranty (providing you do it properly), but your bike will probably fail an emissions test technically making it illegal for road use.

[ Back to Top ]

·  Is the stock carb needle slotted for adjustment?

In the U.S. no
In Australia yes (other countries may also vary)

[ Back to Top ]

·  Do I have to re-jet if I replace the exhaust pipes?

Depending on the manufacturer, if you only replace your pipes and not your airbox, you may not have to rejet, but always check with the manufacturer’s recommendations. Because if you do damage to your bike because you did not rejet despite manufacturers advice the damage will not be covered under warranty

[ Back to Top ]

·  Do I have to re-jet if I replace the airbox?

Typically yes. Changing your airbox to an aftermarket one usually adds more air to your carb, which in turn can create a lean condition (the fuel mix burns hotter). If you do not re-jet after changing your airbox you may do serious damage to your Road Star’s engine and it won’t be covered under warranty

[ Back to Top ]

·  What other carbs can I use on my Road Star?

Mikuni 42mm, 45mm and 48mm Flatslide carbs
Other carbs have been known to be fitted (such as Webber carbs) although they require extensive modification

[ Back to Top ]

·  What is the PMS?

Primary Mixture Screw. The PMS is on the carb and you adjust it to change low range performance and mileage of the Road Star

[ Back to Top ]

·  What is the stock carb?

The stock Road Star carb is a single 40mm Mikuni, model #BSR40

Road Star Parts and Accessories

Question

·  Do I have to use Yamaha accessories and parts for services?

Answer
·  Do I have to use Yamaha accessories and parts for services?

No you don’t. There is a huge range of aftermarket parts available for the Yamaha Road Star now and quite a few of them are much better than Yamaha’s own. Keep well in mind that if you use the wrong part and it causes damage to your Road Star, it and the damage created will not be covered under warranty

[ Back to Top ]

Big Air Kit. A BAK is an airbox and filter offered by Baron’s Customs

[ Back to Top ]

·  What is the part number for the Silverado Saddlebags Brackets and the Tour Classic Saddlebag Brackets?

Silverado Saddlebag Brackets for Road Star: Yamaha Part No. STR-5GA73-40-00
Tour Classic Saddlebag Brackets for Road Star : Yamaha Part No. STR-4WM73-40-10

[ Back to Top ]

·  Can you use Silverado Saddlebag Brackets with Tour Classic Saddlebags (and vice versa)?

No you can’t. Yamaha lists different part numbers for the brackets for the Silverado bags and the brackets for the Tour Classic bags. They look very similar but the mounting points for the bags are different. You could make it work if you were very handy with a hacksaw and welding equipement, but it probably isn’t worth your time

[ Back to Top ]

·  Can you use the “Royal Star” Tour Classic Saddlebag Brackets on the Road Star?

No you can’t. The brackets are different for the Royal Star and can’t be used on the Road Star. You could make it work if you were very handy with a hacksaw and welding equipement, but it probably isn’t worth your time
