Weber selection and initial jet tuning

Recommended Posts

Absolutely, following along to increase my limited knowledge, even though my triples are pretty well set.  Love the tinkering with jets, etc!

Yes me too. Even though I have Mikuni's. The only thing I noticed was in all the years I have talked to others about

Weber and Mikuni, I have never run into anyone say they were using a air jet over 200. I must have missed something along the way.

Otherwise they would not make them I guess.

Heads Up!  F19 tubes enroute to you from Europe 🙂

Thanks! Looking forward to seeing the difference.  Glad to know so many others are learning from this thread.  Hopefully it helps others in the future too.

Ok, got 4 logs in today and I also managed to get the RPM sensor working!  I noticed though that the revs read about ~800 rpm lower on the logger than the tach....not sure which is correct. I rev to 7K when I test on the tach. Maybe tach needs adjustment? Dunno. 

F16 155/215...I didn't have 160's.....but looks like that might be the sweet spot between the 155 and 165.......First run was in the morning...last 3 were in afternoon with a bit higher temps.

Looking back on my logs, it looks like I do have 160's somewhere. I'll look around harder tonight. Also we did the 160/215 combo and it looked pretty good back then.

Cool!  I found the 160s tonight and installed them. I’ll retest in the next few days.

A couple side notes. I noticed the cruise has now been very rich. I believe this is due to the 70 idle jets. I am going to go back to the 65's to confirm that is the issue.  

Also, after inputing my info into this gear ratio calculator; https://www.blocklayer.com/rpm-geareng.aspx

I do believe my tach is reading high and the data logger is correct. So I will try to dial that in as well.

6 X F19 tubes have been shipped from carb.deals on Ebay. 

They are shipping from the Czech Republic.

I highly recommend Carb.Deals. Great service, selection, pricing, and quick shipping:

Here is their store front:  https://www.ebay.com/str/CarbDeal?_trksid=p2047675.l2563

That's who I've used too! I agree, great service and prices. Thanks again for sending those.  

I put the 65F9 idle jets back in and afrs are leaned back out at cruise and looking good.

Got the F19's in with 165/215.  Drove it last night and didn't have a chance to get a log, but under WOT the AFR's were way lean....like 15's at 5K.

Looked last night and 165 is the largest main I have. I could try a 185 or 175 corrector to try to richen it up.

Yeah decreasing the air corrector is what I meant above....215 is in there now.....I have a 185 or 175 I can jump down to.  I'll try to get one of them in tonight.

Put my 175 correctors in for a 165/175 combo...it's certainly richer and looks good for a while and then starts going leaner as RPM raise. I forgot my SD card today so I can't get a log.  I will try tomorrow.

Wouldn't a smaller main make it even leaner? Right now I'm running what is essentially the "richest" combo I have. 165 main is the largest I have and 175 corrector is the smallest.
