carbs

I recently bought a 79 xs650 special with out carbs. Today I found out a buddy has a 83 heritage special that he is chopping, he offered me the carbs but I don't know what kind off carbs they are and if they will even work with my 79. I heard I could use the bs34s or the bs38s. Is that true...

I've been having on and off carb issues. I have pod filters and non-baffled straight pipe exhaust. Recently installed Hugh's hand built PMA. I have Bs38s and on my 1978. Main jet = 145. Pilot = 45, I changed both. Mixture screw is at 3 turns. At first, my bike would not idol correctly, it would...

I have a 1977 xs650. Bike starts up fine, but when I ride, I'm getting a shortage of power. I've battled wiring/electrical problems ever since I bought the bike. I redid all the wiring, because fuses kept blowing. But now the bike just isn't riding right. I tested the stock regulator and...

So I recently finished rewiring my entire bike, kickstart only. She has been running great for the most part, just some problems at idle. So I went a tiny bit bigger on my pilot jets to help with the idle, also I was running a bit lean so I went form 125 main jet to 130. Then to finish the look...

So I recently bought a 1980xs650g, i love the thing, I've been replacing a lot of things on the bike, mostly the basics, new carbs(broke old ones), oil change/filter, petcock fixed up, etc. I've been having some bad wiring problems with fuses burning out, namely the fuse that leads to the...

Hey there everyone. First post, first bike, first build. Picked up a mint 1980 special, without carbs however. I need to get an out of province inspection done before I can start digging in. So I need to get a new set ordered and I'm not sure which ones to go with. There's a PWK Carb kit on...

So last nite while in on my death bed with a cold I was invited to one of the little bike shops here in town for a after hours session to work on my carbs. Definitely could not say no... Ill try to describe it best I can, but its on the side of the carbs, the throttle opens and closes it. I...

I'm new here - I have a 1980 2FO model with BS34 carbs. The symptoms are a huge miss like a dead cut at 2500-3500 rpm on small throttle openings. I researched here and pulled the carbs apart and cleaned etc. The needles were worn, the pilot jets were out of the BS38's, one diaphragm was leaky...

I currently don't have to do this because I did it when I had the stock air filters on but it came to thought the other day. When syncing carbs with pod filters is there anything different with the procedure that I should know? Using gauges of course. I was thinking this because the PCV...

I sent my carbs to Oldschoolcarbs in February, Jack at Oldschoolcarbs said 10-12 weeks. I said no problem, rebuilding engine. I have not heard a thing from Jack and he has not replied to my email. I'm begining to think I'll be in the market for replacement carbs soon.

Has anybody used these carbs, I was going to replace the stock BS38 with a set from Heiden Tuning KEHIN PWK 32mm. Before I spend the pounds I want to be sure. I have searched the forum and one reply was cheap rubbish

Trying to get my bike running and I think I have one of two issues, too rich from the carbs or my coil is weak. Randomly the bike kick over fine and fire right up. Idle and run with choke out. I push it in and it lowers idle and things are good. Other times I kick and kick and kick and...

I'm running a 5/16 ID fuel line from the tank through a brass T fitting into two Mikuni Vm34's. I've double checked everything, the petcock flows freely, the gas line is free of debris but when its all on the bike together the fuel doesn't flow freely. there is a tiny bit of flow and air all in...

Sorry for the length!! Alright guys here is a little background info. I bought a 1976 xs650 back in August and totally stripped it down to the frame to rebuild it over the winter. I sent the motor with about 14,000 miles on it to a local motorsports shop near my house for a top end rebuild...

'77 running bs 34's and TCI ignition..... After pulling and cleaning and cleaning and swapping bits and pieces between a set of rebuilt '80 brass float 34's and a set of '81 plastic float 17k miles 34's and still not getting the right side to fire consistently I swapped plug wires. Yep...

anyone know of where i can get a set of vm's i hear they are really reliable and bot to hear a bike running with them and it was awesome!

Hey guys! Ive got a 81 Heritage special I hardtailed, painted, tuned and everything. Some of you guys might even remember me. Ran amazingly all last year and this year. Sold it to a guy, and after about a week, the thing starts dying, turned out to be a ripped slide diaphram. Changed and...

Hi folks, I just bought my first XS650. It seems to be a well taken care of 1977. The previous owner claims he rode it regularly until about 8 months ago. But, I've been having some trouble starting it keeping it running. I took the carbs apart and cleaned them and then it started right up...

Do I raise the clip to lean, or do I lower to lean

Hi guys, I purchased a 1979 XS650s last week and need some help regarding tuning. The bike is equipped with the standard 38mm carbs. The only modifications are K&N filters (OEM style, not pods), XS1 style header pipes, and Dunstall British style slip-ons. The problem is that the bike falls...
