Well I just Purchased the $380.00 S stage 88cc bore kit. I got the hook up. I didnt pay full retail!!
Potential has the same setup and cannot fine tune his to were it runs right! They say you need the 20 MM carb instead???

Whats going on. How can the 18mm carb they have been selling for a while not run right with the 88cc bor kit. Runs to rich..

Who knows the real deal on this.
Fast 50's say get a 20mm carb or put a 75 mm main jet instead of the 92 or 85 that comes with it.
Sano has no idea even the guy who works their said his did the same thing
Two Bros said to buy and exhaust !
What idiots
HELP SOMEONE please

should have got the light bore kit for sic 50's and kept every else stock the pipe carb and air filter just put a 60 main jet
the only time a bigger carb will work is if you have a bigger head then you will need the extra gas
many people on this site have the light bore kit and love it

take some time and do some searches you will find many old post useful

Get the P244 jet kit from Classic Minitrails and reduce the main jet size from an #85 until it runs clean on the top end. On some of these setups it works well to change the pilot jet to a #38 also.

well thats a problem. They dont make a smaller pilot jet and they dont make smaller jet sizes for the 18mm carb. I talked to Darryl from SIK50's and SIK50's NO THEIR ****!!!! SIK 50's rock !!!
He said to fill the pilot hole with soilder and drill it out . Also the heads are stock. So this sucks. I am going to rock the stock carb untill i find away to run this 18 mm carb the right way !

Richie

any other suggestions will be much appreciated !

The main and pilot jets for the 18mm carb and 20mm carb are the same. If you are still in doubt, give Lyle at Classic a call.

sell your 18mm carb

get a 20mm carb, 70cc head, protec pipe

then you can pimp

will the 18 mm carb not work for the 7o head?

i installed everything used the 85 jet and all the way up on the needle. i am testing and tuningt oomorrow morning.

yeah my pc18 carb just wouldn't run right. the idiots at classic sold me the carb and a jet kit (#'s 88-95), just to turn around and say "oh, well you need a 75 main jet to get that thing to run right, and a smaller pilot jet too... oh but they don't make those." i was like WTF are you clowns talking about?!? they claim they know all about the products they sell yet every time i have a question they have to put me on hold to go ask around... so i made'em take it back even though i used it and i got a pc20 carb overnighted to me, which should be much easier to tune. i'll update later.

rich i think you'd just need a new intake manifold to match the size of the intake port on the 70 head. i'll look into it this weekend.

Ok well DUDE is selling me his stock 50cc head that has been port matched to a 20mm carb. All for 50 bucks with no cam.
The stock piston, head everything but ported and will run great with my 18mm carb. So i will roll out the right way. None of this crazy jet and solder and drill ****. You need to open the head to breath more for all this air u are cramming in their

My is going to be

Actually the 18mm carb is WAY better than the 20mm. There was just a thread on this the other day. Silver Surfer was complaing of too much airflow cuasing bogging and wished he had got the 18mm, every person with the 20mm agreed. Also, contact 2bros, they carry different pilot jets for the 18mm, trust me, the 18 will run A LOT better than you will ever get a 20mm to run. If you can get your 18mm carb running right you shouldnt have a bigbore.

lol i love this thread. i swear by the 20. u gotta have patience my friends. they do work. trust me. there's a fleet of em over here that dont miss a beat.

potential

hb where is that thread? i wanna check that out. from what all the 'pros' have told me is that the pc18 is becoming notoriously difficult to tune properly, although the 17 and 20mm carbs are known to work really well. and the fact that takegawa has recognized this problem, and changed their s-stage kit to include a pc20 instead of 18, as well as the fact that there are so few parts to properly tune the pc18 (jet sizes, pilot jets, etc etc.) doesn't support you're argument at all. i'm still not convinced that the 18 would work better, although the 17 might. i'll hook up a pc20 tomorrow and see what happens. thanks fab5 good lookin out.

hb five0 rider

why would you think that a 17 would work better for you if you cant get an 18 going right? i told you that two bros carries all the stuff you will ever need for the pc18, nearly all the same stuff as the 20. seriously, doesnt that sound more logically correct that the 20 would flow too much over the 18 causing it to bog...where did you read TG was now included a 20 carb instead of an 18?ill find that other thread in a second.

I am sticking to my 18mm carb and i found a used xr 50 head ported out to match the 20mm carb by JCminis.. I will be able to run my 18mm carb with no problems i hope. Should run really really good. Stronger than a 18 or 20 with out a head thats for sure!!

My Tagawawawawawawawa kit ran perfect out of the box. I bolted on everything that they gave me and it ran brand new - Thats why I bought the kit - cause it had the matching carb, cam intake to the kit. No f'n around w/ jets - I learned my lesson on my last quad that I had.

Thats even w/ the stock exhaust - Im thinking of putting a pipe on it now.

1000 ceecee I go tthe same kit. What size jet did you use. The Takegawa kit comes with 2 jets. a 85 and a 92 jet. I am going to start tunning it soon. I cant wait to recieve my head in the mail. Then i should have no probs.

Thanks y'all
Keep it real.
Soon all my boys will start taking some pics and we'll show you how us NO. VA fiddys riders rock it...

so i hooked up my new PC20 carb and that thing ran great no adjustments needed to the needle or airscrew. f*ck the pc18 it's a piece of **** the 20 runs strong and hasn't bogged at all for me, even when i first started it (i ran it and tested it out inside @ ~65 degrees but it's ~20 degrees outside and it ran fine in both).
