Open belt primary 3 Years ago
|
|
|
Ok guys I really like the look of the open belt primary. I'm running my drive belt w/o the lower guard and pulley cover off. I want to try and go from a chain primary to a belt primary but I can't find anything anywhere about a yamaha setup. All I find are HD setups form about 600 dollars on up. Anyone know if a conversion is even made for a roadstar or if there is an HD model that would possibly be able to convert to fit the roadstar. If so what am I looking at fab. wise. Really like the look but cant find squat. Any help is appreciated.

The Road Star doesn't have the same type of set up as a Harley. Our bikes have a transfer case after the transmission in the stream of power transfer. In other words, there is no "primary" like on a Harley.
I suppose you could expose the transfer case on the right side with a belt instead of the chain. 
Good luck! |

No can do.
I suppose you can expose the transfer case chain but you would need to change the chain ... there is not belt for the right side transfer case setup that I am aware of.
You can also do a right side pulley setup and eliminate the pulleys on the left.

Open chain sounds somewhat cool; however what kind of chain would I be looking at and since the gears and chain are in a wet environment, what downfalls to this setup would or could exist. As far as a right side setup you are refering to the drive belt and sprockets correct. I'm just trying to exauhst all possibilties before jumping in headfirst like I usually do. I know the possible hazards associated with removing guards and whatnot but it aint like im riding around in shoes or flipflops with baggy pants 
Thanks for the input guys. |

There's the rub .... the OEM chain needs to be lubricated to minimize wear and tear. You would need to find a drive chain that would be the right length and fit the sprockets. 
There's a member who has done the right side pulley setup ... you need to look to him for advice 'right from the horse's mouth'. 
Try doing a search .. I think he posted some details within the last 6 months.

On a Harley the transmission is not part of the engine, it is a totally separate unit. The primary drive connects the engine to the transmission; it is normally a closed housing with a chain and a wet clutch. The open primary uses a belt instead of a chain and uses a dry clutch instead of the wet clutch, and of course the housing isn't covered. There is no primary on the RoadStar.

I understand that this a onepart setup, engine and tranny together. Guess I should have clarified a little better at the start. If the tansfer case has a two gear and chain setup then my thinking is that the gears should be a 1:1 ratio which whould mean quite possibly that I could go with new pulleys designed to run a belt on. Am I thinking correctly or am I off. My minds in full gear right now and I aint gonna be home for another 24 days to a darn thing about it. Oh well gotta make a living. thanks for all the input so far, keep it coming.

So you want to go to right side drive. Put a belt pulley on the output shaft of the motor and run a belt? Get rid of the transfer case altogether.

Muskey that is definatley an option. But could I keep the transfer case and just go with a belt setup. Not against the rightside drive at all I think they're pretty cool, but thats been done. I haven't seen anyone run an open transfer case with a belt. Just something I wanna try. Maybe it will work maybe not. Just fishing the idea right now.
