Head and Carb questions!

CHB73SB · Posted: Tue Jun 23, 2009 10:47 am Post subject: Head and Carb questions!

Hey everyone I just ordered the SCAT 1776 engine rebuild kit from CIP and was wondering what heads and carbs i should run. I have some in mind but i just wanted to hear oppinions from others. I was thinking the Los Banditos from CB http://www.cbperformance.com/catalog.asp?ProductID=1470 with the Dual springs. And a set of Empi HPMX 40's. What do you guys think of this? I am trying to keep it on a budget as i am a student, father and working 2 jobs to make ands meet. Thanks for any and all advice and input!

Chris

Not my personal choice but should be a snappy little motor. My last trike had that combo and it was a snappy,reliable motor. Think about an 010 or 019 with that combo and you will be good. Don't get the dual springs unless you have the cam to support it though.

You didn't mention what cam you are going to run but......those are good heads especially with dual valve springs. For carbs, I'd get a set of 36 or 40mm Dells and rebuild if needed (or even Kadrons and rebuild) there are plenty of them on the classifieds. You'll more than likely need to take the HPMXs apart and do a thorough inspection, they aren't known for their quality. I know you are trying to save some bucks but carbs are one area you don't want to cheap out on. When the motor dies late on night or won't start when you really have to get somewhere or you spend hours and hours trying to just make the damn thing run right....you'll wish you spent a little more on a quality set of carbs. I'll climb down off my soapbox now.

Anyway, Go with the CB heads, some good Dellortos (or 40IDF Webers) and the only other thing I would recommend is pick up some CB lightweight lifters along with the heads. Scat lifters don't have the best reputation. My 2 cents.

Oh yeah sorry guys i forgot to mention the kit comes with SCAT's version of a W110 cam. And the scat l/w lifters. Here is the kit I ordered https://www2.cip1.com/ProductDetails.asp?ProductCode=C15%2D1776 . And i know i should look for some IDF's but there is a huge price difference, and not to long ago i was talking to Jake Raby on the phone and he said that he has had better results with the HPMX's. But that is just one man's oppinion. I am trying to stay in the $500 range on a carb kit. But i guess i will have to see if my pockets go any deeper???

I guess another option would be to rebuild the Progressive Webber i have on a T-4 engine in the shed and get a new intake?

Kadrons. I've used them, never a problem. Good carbs for smaller motors.

Let the flaming begin! Laughing

I had seen this and did think about it but i am just a fan of the IDF/HPMX set up! I have a feeling that they will give me better gas milage. As this is my daily driver and with gas prices going back up, i guess it would be better to spend the extra money now than over the next few months in the tank!?!?!? Question

Sounds like you've made up your mind on this one already. My one last piece of advise then is to do a search on HPMX and Progressive carbs. See what comes up. Read, learn and then make your decision. Good luck!

If I remember correctly he told me that Bugpack had asked him to do a test for them.. and he told me he had a 70% failure rate with the IDF's and out of 40 pair of the HPMX's he only had a return on one single carb. But then again i don't know if the IDF's he tested were the originals or the new USA crap they are selling now. Maybe he will chime in and help to clairify....

And BTW Darth i did call the guys at LowBugget and i am considering the Kadrons but i think i will try to find some good IDF's that come tuned for my engine! I do agree it is a good way to go it is just a cost thing that is detering me..

Thanks again for all of the input guys.. If you have anymore suggestions please feel free as i am open to new ideas this is my first engine build.

I was also wondering if there is any important preventative measures that i should put in place while reassembling the engine? What ignition should i use, Oil cooler, etc...??

hpmx VS american made IDFs
sadly the hpmx has better QC than the weber

id still prefer buy a nice used set of italian weber or dellortos

Would a set of baby Dell's be enough for this setup? I think i can get my hands on a set of FRD 34's.

Those empi carbs are GARBAGE.

The are a little better than when they 1st came out.

Still Garbage

I would never recommend them, or associate my name with them... For any price.

I am using the hpmx 44s on my 1914.I bought them around may 07 and havent had any probs with them.They are used in a sand rail with sandy dusty enviroments.To date i have only had one plugged idle jet,have not had to resync,and no troubles with them.They were even partially taken apart when i got them no springs poped out,were clean,made a slight flaot adjustment on one carb.

Out of all that bash them i wonder how many have actually used them or is it i heard it from a friends cousin who dads brother had them.

I know the first ones had many probs and for this reason i would not buy a used set unless i know ehre they came from and when.

I use what works and I do not operate with a closed mind as everything changes constantly. Those who are not constantly evaluating the market lose sight of what is actually available currently.

My endorsements are not for sale. The insinuations that have been made earlier in this thread that somewhat suggest they are is absolutely, 100% inaccurate.

The fact is these carburetors function better than a brand new set of USA Webers as of the data of this post.

One of my customers who builds vehicles and uses engines from me and another supplier had to fly to the UK to remove a set of USA Webers and replace them with a set of HPMXs last month. That was an 8,000+ round mile trip to remove a component only to have it successfully replaced by a component that many believe to be inferior.

That said, off the shelf the HPMXs need work just like most everything else. Empi has been more than open to the suggestions that Art and I have given them about these carburetors and how to make them better and I can't say that about most anyone else.

Like most anyone else in this industry, I have been displeased with Empi over the years but I can't argue with what they have done to make these carbs better over the past two years.

These posts are in no way an endorsement for any Empi component. I am merely stating what I have noted during evaluations and what has proven to work best with the least manipulation as of recently. Just because I am using these carbs, don't think you can pick a set up from any vendor, bolt them on and have them run perfectly.

The HPMXs do have potential.

Thanks for all the input guys! I was also wondering if you all think it would be ok to just cut the old heads for the 90.5's grind the seats and re-face the valves and use them?

Just trying to think of ways to cut back on the $$$ spent.

Also should i order a new crank assembly or use the old gear, dis. drive gear etc...? And what about rocker shafts?

So i just got the engine out of the car and started to tear it down and was wondering if my case would be acceptable for this butild. There is no casting # below the alt. stand and on the side of the sump on the 1-2 side there is this. 2BR Brazilian 26 043 101 102A AS41. If the case is in good condition, should it hold up for what i am trying to do? I am also considering putting a turbo on in the next couple years and just wanted to make sure it will handle the extra stress.
Thanks.
