No gain with 3x3 mod?

Recommended Posts

If someone knows what to do or a thread that can help it would be greatly appreciated... I have a 2009 SM with about 11,000 km on it... I just put a JD jet kit in. Red needle, clip in third spot (elevation is 1500 ft) with a 155 and 25 jet and screw turned out 2.5 turns from being seated as per instructions. I also went one tooth smaller on the front sprocket

 

     I took it for a test ride and it doesn't feel like there is any gain at all... When it was stock I would try wheelies and it would barely get up in first (let off gas then full throttle), second wasn't a hope. And no clutching methods worked at all ever either.... I'm just wondering if the carb is not set right or if maybe there is some underlying problem of the bike. From what I have read, it sounds like everyones is a lot more powerful than mine and I can't figure out why.

When I try with the clutch it just kind of jerks me ahead a little bit.... I mean I expected to be able to at least just twist the throttle in first and bring the wheel up..... But unless I did something wrong with the jetting, I feel that it was a waste of my $115

i dont see why it wont. Does it bog down at rpms? Or slow thottle response? Just weird how it doesnt wheelie? I can wheelie a 125cc in first what has 12hp! Whats your gearing?

If the rpm is real low, like almost stalling it will bog but that is it... Gearing is all stock, only things I have changed on the bike is a 14t front sprocket and now the 3x3. It seems to idle and run fine with no issue. But then again I know next to nothing about fuel ratios and carbs and such.

hm. I would of put the 150 jet in .. Did it wheelie before the mod? If not i reckon you have some powerloss somewhere. The bike has 34hp should lift in first 24/7

I could maybe, but I think that one is for higher altitudes isn't it? Just twisting the throttle in first while moving would never lift it, even before. I would have to go 0% throttle then 100%.... Might valve clearances be cause of some power loss? I don't think they have been adjusted. I really do not want to have to take it to a dealer and pay them a bunch of money for them to say its fine.

well im at 600ft with blue needle at 2nd from top 160 main jet 25 pilot 2.5turns. How many miles has the motor done or since a check. Is it sm? I carnt help much cause im guessing iv not been on the bike etc but trust me i should power wheelie in 2nd if not 1st then in my mind id be thinking its a loss of power. Maybe low compression. Rings/valves etc or the clutch plates are worn but they usally slip and vibrate alot.

I'm 1500 feet and it is bloody hot and humid here. I just don't know what things like moving clips would do. Hell, not sure if the motor has had a check ever. I think I might go do a compression test. Clutch seems to be good, and I know what a slipping clutch is like. (toasted one on my 370z, but 650 hp will do that)

You're only supposed to put the red needle in if you're above 4000', or if it's unusually hot and humid where you are - which I doubt is true for Saskatchewan :)

 

Try the blue needle. Spend time getting the fuel screw exactly right - it makes a difference to responsiveness and 'solidness' of throttle feel. (Big difference IMO.)

Ok I will go swap in the other needle, at least thats only like five minutes to do. Also its been 30+ degrees here all week with 100% humidity. Thank you, for an online forum this one is oddly helpful and not full of annoying ass kids, how refreshing.

moving the clips up higher the needle letting more fuel in. .. Whats to top speed of the Z? Around 90-100? Is there any funny noises? Like knocking? I would buy a compression tester cheaper than paying labour . Also the valves if i remeber correctly exhaust should be 20-30mm intake 10-20mm 'valve clearances are easy' if your unsure you need a to check out E.marquez he made a topic

Top speed is about 125kmh ish, haven't had a chance to run it up that high being in a city... No knocking, just normal vibration at that speed that my gf would love lol.
