HSR 42 Questions/concerns 1 Month, 1 Week ago  
I'm getting closer to the point of giving the HSR 42 a shot. I have the stock carb tuned pretty damn good, so my main question is what difference will I notice with the 42? I am not expecting some gigantic difference, just something a little more peppy.

I am going to be using Sscustomcycle.com, as I like that Shane offers a complete kit. No yost power tube.

Does anyone run just a pull cable and no push?

Last concern as of now, I have a LA Choppers XXX intake (I think it's made by Barons) fits nearly the same as my BAK did. Should I run into any issues using this intake and the 42?

ANY other advice you think I need to know on the 42 is GREATLY appreciated.

The 'push' (actually a return pull) cable on my stock carb BROKE about two weeks ago so I pulled it out and have been running just the pull since then. Works great. Not sure how the 42's set up but the single pull cable's been on bikes for decades...

I ran a pull only on my hsr for years without issues. The mouth on the hsr will be slightly larger than the oem. I dont know how the la chopper air cleaner fits but with my old forcewinder i needed a special part to make it fit due to it being a oring slip fit. If yours has a rubber boot you should be good.

Power wise. You might get 1 or 2 hp. But the throttle is pretty crispy as you do not have the lag of the cv slide like on the stocker. Also you can go gravity feed without any concern for sucking the bowl dry.....ever. provided gas is flowing from the tank that is.

Really thats it.

Thanks Jason.

I am trying to convince myself that I really NEED to get one going pumpless would be a relief, I carry an extra fuel pump on long rides but it would one less worry

I rode Curtis bike once, but it had the 45mm, wow, I still remember riding that thing. It was aweosme throttle respomse

My air cleaner has the exact same rubber boot that my BAK had on it so I'm guessing no issues.

JMO but if I didn't install my Big Bore and was still running an all stock engine I wouldn't waste the time or money on an HSR carb. In fact I did that once on my stock motor and took it back off and sold it to Jake. I happily reinstalled my OEM carb. If you want to get a little better response from the OEM carb pull the slide and you will see 2 small holes in the bottom next to the needle. Drill those holes out to the next size up drill bit (I don't remember the size) that will give just a tad bit better throttle response if that is what you are looking for. As for the pump, I'm running a pump with a HSR 45 on my bike.

Thanks for the info! I may try that with the slide, that's really all I'm looking for is the throttle response.

I run an HSR42 pumpless and a Baron's xXx with a pull cable only Guess great minds think alike. It all works out just fine. There's several tech articles on here for getting it tuned in just right. Just remember, once you go to a slide, your fuel economy is determined by your right wrist.
