this guy's site is kind of hidden. I don't know why the links don't work for me, but this should help you out a lot!

Dude where did you get new studs??? I'm probably going to go to a hardware store and just cut some threaded rods to length unless you know of something I don't.

Just for safety precautions because I don't want them to break on me.

as far as studs go, i would think the tomos studs would work from treats. the ones i used were from an old parts engine i bought on ebay so not much help for you there...

i am thinking i will get a UNI air filter sooner than later. I have got jets ranging from 46 to 60. i had the 60 in and it was sluggish, put the 56 in and i am good for right now, again stock filter right now.

i took the pipe in today and they will have it ready for me tomorrow. i taped and tested it today. was a bit better than i remember my stock pipe to be, only hit 30 on flats tho. again it was taped on so...i'll probably ride tomorrow and report back after i thaw out.

Yeah I think I'm in need of a jet already too. Even though I have the 58 break in jet in there with this

It gets way better low end response I am very pleased. It was 16 dollars from a UNI dealer. Part number UP4200. Don't worry that it's 4 inches long (a tad long) it squishes to fit like a glove.

Waiting for my pipe too! ...to arrive though:(

From what I've read bing jets are identical to encarwi? I'm hoping u get to 35 man, but I'm not sure if these lauras will be able to handle it w/o port jobs.

ok so i hadn't had my coffee when i replied to this today lol. i too hope for 35. Crazy Wayne/Fast Bat. has posted a lot of helpful info on the wiki that makes me think with a bit of work i can make it pretty easily.

if you don't mind emailing or posting the site you got that air filter from, i found one but will cost 25 bucks vs the 16.

if i were you i'd buy bing jets from treats in the range of 56 to 62. That way you are covered for summer and winter. if you are putting that pipe on 60 to 62 is what i am guessing you'll want. stock a new 58 or 60 should be good with that highflow filter. Now as far as what is posted on his ebay store, if you don't see it email him and see. all the sizes i purchased were not shown at first. he will post them for you.

i have started some porting, exhaust. i need to smooth it out though. that is what i am going to do tomorrow evening. i am thinking of delving into intake and carb but not wanting to mess them up...

well i found a place in town that will order me the filter no probelem. seeing as i don't need it right away it is going to save me like 10 bucks, thanks for the help there.

tomorrow i am going to take appart the engine again and refine my exhaust port work. i will take pictures. hoping my side stand and other parts come in today or tomorrow so i can be all ready for remounting my pipe. if everything goes to plan i will be able to pedal and have a short header for my estoril. really which my tomos wouldn't have crapped out cuz that pipe was killer on it. just to many issues to make me confinent with that one...

did your pipe come in?

Also I have never succeeded in removing my crank and that's what is holding me back from getting the engine case out of the frame. If you have any tips on how to get that big pulley out of the way post ur thoughts man.

firstly, pics are coming this weekend, no worries!

ok i have the pipe on and unfortunately it didn't make pedal clearance but with my torch and some help from a friend we are going to bend it slightly to get the clearance i know is possible.

here is the scary part... my bike will not idle anymore... i dremeled out the intake and the carb. it takes a bit to start but does run fine but then the idle will not hold. anythoughts on this? if i adjust the screw all the way in and up at the throttle screw out the lead cable at the top it will hold but is reving way to high and almost engaging the clutch.

it may just be a small shard of metal got stuck in the idle jet deal. the only things i did were the exhaust and the carb/intake. i have not got my UNI filter on yet.

as far as removing the crank...i do not have any ideas for you there buddy... maybe one of the more seasoned Bat lovers on the forum might help us out with these issues. Tropibat and Fast Bat where are you??? :)

big pulley just slides on i think, might have a circlip, cant remember exactly.. actually yeah, i'm pretty sure the little black plastic spacer is all that holds it on, aside from the pedal arm.

He beat me to it, but yeah! That's the whole process.

Drill a 1/32" hole in stock carb to vent float chamber to back of air filter/box. see pic.

Helps stop 4stroking at top sped.

Plug vent on float cover.

O and i have made 7 13mm Encarwi intake manifolds and 6 15mm intake manifolds for SHA's

Fast Bat out

And make the (I) notch on the slide look like a (Y) 50%(I) 50%(Y) see pic.

Shod help idle .

I hope you did not cut the venture floor down where the slide sits.

Fast Bat out

No the red stick marks the spot to pin drill fond better pic.

Stops air presser from pushing gas up the jet like a choke wood.

And yes 13mm stock or 15mm sha working on 15mm PHBG right know.

I E U

Hey folks, i just got a 78 starflite and i am looking into carb options because mine is leaky and finicky, is the stock one salvagable or should i just go with a Dellorto SHA 15mm, or even one of the ebay dellorto knock offs? Thanks.
