Would a 135 main be to lean with a b pipe or would I be pushing it? I am planning on changind it next week when the new ones get in just want to ride tomorrow but dont want to lean it out and blow it up..

They both have numbers on the head and the 115 came out of the main hole. The low jet had the number 120 on the side so I left it in there

Opened up the carb.....had a 115 main in it....it was suppose to have a 135.... what would that cause it to do just run a little lean? Seems like a 145 main is going to be a HUGE step... Just tried to install 145...the head is tooo big does it have to be drilled or did I get the wrong jet...

I found a 145 main today at a local shop but the pilot is 122. What will running a 122 instead of a 120 do....just run a little rich? What do you play on the crack box? gamertag bkilled2000

Does it usually say on the jet, the time or two I have takin them out i cant say i payed attention but i dont remember any numbers on them. Maybe or maybe :) great answer:banghead: Are they sketched in the jet somewhere?

I have a stock 61x motor dunno what jets are inside the carb right now but i installed a b pipe and forgot to order the jets so I ordered them long story short now it will be next week before they get here, Can I open the high and low up and run it for the weekend without blowing it up? have...

Think I will leave the extra big one alone plugged into a pisser with the restrictor in it, but what do I do with that little piss ant one?

First of all there is no room where the head pipe meets the b pipe, THAT SUCKS, I grinded some of the hull where those spots that stuck out higher down flush and it helped but not much. 61x motor The Problem My head has 3 places for water lines, See pic, 2 are normal size ones a piss ant...

How did you end up getting it off, looks like you did some cutting on it:puppy_dog_eyes:

...I had two different jetski shops break a tool at each one, guess I am gonna grind it down and grab it with a pipe wrench or buy a new pump, I looked up the shaft and I think its over 200 bucks...

Yeah i keep hearing that too from this board, I have spent over a week defoaming mine and it wasnt even a problem when i cut into the ski

yeah, was at two different jetski shops..

I rode a rn (I to have a 701 square) and after a few minutes felt like it could be thrown around alot easier then mine, his would also do over 50 and had tons of low end power. I wonder if its more hull then motor.

So I have broke two solas tools in a week span trying to remove the same impeller, Used torch both times, should I just cut the dam thing off? Sucks having a brand new prop on the shelf and look at this ugly thing in the pump... Its on a superjet

:burnout: :lightning: I was saying my motor is not worn out and it still turns over easy :) figured if I left out my compression someone would say its prolly just my motor is worn out and I need a rebuild

Motor should turn over easy with plugs out and turn all the way over and not get stuck Thats the key to what he is saying ;) other wise I would say the starter is prolly bad to How is the 550 running ger, did you hone it out and install a new set of rings? I hopped up the last 550 I...

yeah sounds like something else, starter is prolly fine, I can spin mine with one hand with the plugs out, compression is over 160 with plugs in. Like borris said either a pump issue or a motor issue.

chart says 14/17 is for a modified engine, you think a motor with no porting 185 compression and a factory half pipe can spin this prop and have anybottom end.. thanks for the response

I got a 4/17 yes it clearly stamped 4/17 but with my google searches, and board searches I cant find anything about a 4/17...there is alot about 14/17 but nothin about 4/17's.....any thoughts..

Do a search on the other board where alot are banned from ;) there was alot of info if you go under old school and type sbn 44. I am gonna do it later on this summer after I check the ski out with the new pipe, I have three of the sbn 44s extra might as well put them to good use
