I just ordered my cable (finally)

To be 100% sure its the right cable, i ordered the twist throttle one. It has the right ends, but a little extra cable, just wrap it around in throttle body and it works fine I:I
 
so ur saying that it wouldnt fit cuz im not the biggest fan of twist throttles. i couldnt just order a motion pro for a bllaster. and how much u think it would wake my blaster up with that 34mm?
 
I ordered the wrong cable once.

I had a twist on my old one, and my brother has the twist cable on his.

I suggest ordering the twist throttle CABLE. It has the right ends to go with TORs delete.

Its a little long, but it wraps nicely inside the throttle housing
 
ok thanks im getting it a little and im not like a rookie at this stuff haha. i just havent screwed with a different carb before i know a lot of thinks abut blasters but do u have a ny pics idont mean to be a hassle but its a lil confusing
 
and your saying that it will basically slide right in like a normal cable? or wil you have to like wrapp it around a few times in the throttle housing
 
i have mikuni, so its a little different, but the basics are all the same i do believe.

I will show a picture of how i have mine wrapped. Works perfect on both of ours I:I
 
and what do people normally use for their pj carbs with an aftermarket throttle cable. i cant imagine that everyoone does this mod right hahah:)
 
It might be possible to get another hose to go on the ouside of stock size, but im not sure how that would work...

I say buy the carb, and wait to install until you get that boot.

Also you will need to rejet
 
yea ik about the reget i emailed ken oconnor but idk where im going to even start haha its a little overwelming. like i want to know where to atleast start with the main and pilot and then airscrew adjust from there
 
the motion pro tors eliminator cable works with the pj 34.
ask me how i know :)

intake boots have been stretched to fit 34's,
i think by boiling it
the one i know of did indeed split after some time but was caught in time before a massive airleak fried the piston.
i suggest doing it correctly.....

my 34mm pj jetting @ 1800' elevation with KOR porting/head mod, uni filter in CFM box and right bend CT pipe...

48 pilot
DGH needle on middle clip position
155 main/162 from 50's - high 30's temps

alot of others start at 50 pilot/150 main for 34/35 carbs.

i'd get 45/48/50 pilots
148/150/155/162 mains
the DGH needle from here...
http://www.carbparts.com/
just call them to order

that jetting should be close and confirmed/adjusted from there......

check/adjust float height:
