Hello. Got the bikeberry hp carb and it runs too rich. Can someone tell me where to get Jets for this? It says " runtong" on the side. Thanks

I was told by bikeberry After I bought my kit with the HP carb that it has a fixed jet so it won't work in high altitudes.... Which I am in. So I just ordered an NT. Are you saying you really can jet this hp carb?

Certainly you can replace the jet size in an HT carb, BikeBerry if full of crap if they told you that. Both the NT and the HT carbs take the same jets, 5mm, here-----> https://www.ebay.com/itm/5-JETS-Low...133936?hash=item3f45737430:g:70cAAOSwkQZbWOgr

Well hm.. I wouldn't be surprised if they were full of crap. I'm starting to realize how they are like that. I'll have to take apart the HP carb and see for myself... You know I'm talking about the "HP carb" right? Here's the link to it, and if you read the description it states that it does not work in high altitudes because it has a fixed jet needle. Oh and thank you for your reply and advice.

got away from those clamp carbs, worked ok but broke enough to buy good carb. Now I have a 19mm Dellorto carb and almost tuned perfect now. 2x the power at lower rpm in my experience over those smaller carb and intake choices. Head wind wont cause loss of power like with smaller carbs, this one powers right through a strong head wind. Much better experience.

Sea level is where I live the jetting is a 45 pilot a 83 main I have been running 50:1 for the last few months but just bought 2 quarts of 100:1 AMSOIL to start using that again like I was before.

Runs nice and crisp on the 100:1 as long as I do not end up flying over the handlebars trying to avoid people walking around on the street with head phones on looking into a cellphone walking into my path.

That's a nice bike! I'm using OPTI2 at a 100x1 ratio on both of my bikes and they run great.
just got back from another 80 mile round trip using 100:1 and noticed engine has more power at lower rpm it accelerates faster has more torque. for the last 3/4months been using 50:1 AMSOIL Dominator racing oil and it ran fine no smoke made power but the AMSOIL Saber 100:1 has better power for street driving. was very impressed today. used one and a half gallon to travel 80 miles today

Well, I know those 100 to 1 oils will break down under less heat than the normal 2 cycle synthetic oils but the truth is, these little engines don't get hot enough for that to happen anyhow. I like the lower carbon build up and less oily mess in the pipe when you use these 100 to 1 oils.

Javy did you say 1-1/2 gallons to go 80 miles? I've been 70 miles on one tank full, I ride around 24-25 mph.
my bike will cruise 30-40 mph whenever there is room to do it. 24-25 mph is like 1/4 throttle for me. I used to go a full 50 miles per tank with the smaller carb n intake. But the better power from the 19mm Dellorto is safer to fight traffic with.

I understand, I was just comparing the mileage. Georgia law states we have to stay below 30 mph so I try to fly under the radar. 25-28 is a pretty good ride for me, I’ve read some regulations lately that are trying to limit 50cc mopeds to roads that have a speed limit of 35 and under here. Also what’s happening in Atlanta effects us also, scooters and electric rental bikes are ruining our hobby.

everything you read is a fictitious conveyance of language written by a foreign bank.
if you agree to any of it you are agreeing to be an informant to a crime.

I actually blew a stop sign today in front of a cop he was behind a car at the intersection I went through around 30 miles an hour loud as **** my whole exhaust fell off today and here I am posting like 30 min later not in jail or no ticket the cop must of been looking at his phone or who knows what.
