Cool them I should be good to go with that. I did notice that the carb only slide in the manifold about half way before it bottoms out onthe step inside the manifold. What did you do about that?

Re:HSR 42 Information 4 Years, 5 Months ago  
Geeze, ya think I'm gonna remember that? only 2 things I remember about using a stock manifold, 1 was to shave off the centering nibs that are there for the stock carb, this allows the 42 to seat a bit better, and 2 was to take the spacer out of the stock clamp so you can tighten the clamp better since the spigot is smaller than stock carb. I've had the Nemesis manifold longer than I used the stock manifold

Re:HSR 42 Information 4 Years, 5 Months ago  
Yes I got that much I am going to use the ported stock manifold for two or three reasons. (1) I don't want the carb falling out. (2) I don't want any air leaks. (3) I don't want any heat transfer so it pukes. I think if I lube the carb spigot I can slip it in all the way to the carb body I think. I did think about trying to bore it out but seeing as it is rubber that will be very hard to do and keep it round. I am still thinking about things. I am in the process of doing the TPS mod and have found a few things that arn't exactly correct on the instructions so I may write my own in the process for this whole thing. I am really greatful for you input on this Erbman.

Re:HSR 42 Information 4 Years, 5 Months ago  
with the nemesis, I'm using radiator hose, and it won't fall out, that for sure, once that clamp is tightened down, it won't budge, it's solid as a rock. I think those that had more issues are the Ben Hurs friction fit manifolds. I'm also using hand made gaskets instead of o-rings as well, and certainly like the K&N 59-2860 marine filter, this sucker breathes as well as the patrick racing BAK. I hear my babe breathing over the pipes. One of the better air kits I tried, and all of about 90 bucks with stainless steel brkt I made

Yes I took a look at that filter and think that is the way I am going too. I have a BAK that was on the OEM carb but the chrome has become mottled and this bike is going to be about performance not chrome. I have trimmed a ton of weight off of it with the fiberglass fenders already.

Re:HSR 42 Information 4 Years, 5 Months ago  
if ya go that route, just tonight I came up with a way to mount the brkt to the back of the filter. Originally I put a screw thru from the inside and a nylock to secure. So just a few minutes ago, I tried my idea thats been on the back burner. I had picked up some 1/4 x 20 thread brass inserts, think they are maybe 1/2 or 3/8 inch long,, drilled a 5/16 hole, it is a tight fit to get it started, the insert that is. Was thinking to to use some black rtv on the threads so it adheres to the rubberized backplate, but may not be 100% necessary, I did put a screw into to see if insert would twist, it did hold firmly. then use a 1/4 thumb screw to secure the brkts with blu locktite. now as far as the brkts, came up with another idea as well, this would give a bit of leeway room for errors, I would make the hole for the filter side to be a slot, maybe 3/8 long, 1/2 inch? this would allow for some adjustability if your off on drilling on the backplate holes. secure brkt to heads first, then final tighten thumb screws. any way, just some food for thought

Re:HSR 42 Information 4 Years, 5 Months ago  
Thanks I will keep that in mind. I did my round K&N a lot like you did your first try. It seems to work fine on the new bike. I may have to play with welding stainless before all is done I have a few pieces left to fab with.

Yes I won't even try that with light weight aluminium. And it polishes up so much better too.

Re:HSR 42 Information 4 Years, 4 Months ago  
OK got a little problem my tab didn't turn out in the same position as the one in the TPS article. Here is my delima the travel range of the TPS is 120 degrees the travel range of the OEM carb throttle and the 42 is 75 degrees. That means there is 45 degrees that the TPS travels that isn't used which translates to 22.5 degrees on each end of the throttle. I need to figure where it need my two mounting holes need to be to mount the TPS. Here is my thinking I find the half way mark on the throttle and also on the TPS. Set both at that half way mark and locate the mounting holes for the TPS. What do you guys think?
