I have a low mileage 2001 FZ1 that has a carburetion problem that I can't fix and now two different motorcycle shops are unable to resolve. It has the Dale Walker Holeshot jet kit plus ignition advancer and the AIS removal kit also. (Everything set up to Holeshot specifications). The bike...

I have a 2001 FZ1 with Holeshot aftermarket carb kit installed and aftermarket Yosh exhaust and Holeshot AIS removal kit. I had the carb's professionally done at a race maechanics garage. The bike had been sitting 5 months prior. The bike "stumbles" on acceleration....esp. from 3K to 6K rpms...

I have the Gen 1 bike (2001) and have battled this problems for some time. I have found that Yamaha tends to set their bikes up with a VERY lean state-of-tune and sometimes the throttle position sensor is set incorrectly. When I add in a little choke at a steady throttle position, my surging...

AIS Removal Thanks to all of you for your comments and help. I'm sure I'll lick this terrible surging problem. I'm going with the Holeshot Stage 1 Kit....purchased today. I like the fact it comes with an ignition advancer too. I have these on all my bikes and that REALLY smooths out the...

AIS Removal Thanks again Billy... I kind of figured that was the deal with the surging....jetting the only way to fix that problem. I'm wondering if the $25 for AIS Removal is a needed investment at all??? Maybe nice to have if I ever decide on an aftermarket can for the FZ1. What do you...

Thanks Billy Thanks for the reply Billy. I'm going to buy the TPO AIS plugs on ebay which apparently are "self-locking" and do not require any tapping or sealant....just screw them in and they automatically tighten. The pictures of your AIS removal will be very helpful....thanks for the...

I's like to removal ALL the AIS junk off my 2001 FZ1. I found the TPO kit on ebay which consists of 4 plugs screws that apparently completely seal off the inserts into the four cylinder heads and allow you to remove all of the AIS hardware including all hoses. First...does this work??? Anyone...

I tried seafoam already...I actually put it in all my bikes every once in a while to clean the carb's. I guess it could be a carb-related problem...but not sure why the simple changing of spark plugs would have such a dramatic effect on idle, poor throttle response, and a gulppin-like response...

I already changed to CR9e plugs...that's how the whole thing got out of whack. The K&N filter was on the bike....I just cleaned it a bit. Since the CR9e's are noticeably shorter plugs....I wonder if this is the problem? I'm going to play around with a few things and hope for the best....if...

Bought a 2001 FZ1 about three weeks ago. I love this bike! Previous owner did not ride it much...it only has 3750 miles!!! Anyway, I did some routine maintenance, oil change plus filter, K&N air filter, and replaced the plugs. When I pulled the plugs, I was surprosed to find that they were...

Engine missing, new plugs?? Thanks guys. I'll recheck the connections to the plugs. By the way, the bike has only 3K miles on it and its a 2001!! Probably been sitting a lot which may also indicate a carb-related issue???? Anyway, I'll recheck everything and get back to you. I DO love this...

I have this little problem. My FZ1 was running rough, slight surging-like feel but after warm up at least idled somewhat OK. I then changed plugs (four new CR9E's)...there were 4 CR9EK's in the bike???? installed by previous owner. Anyway, now it won't idle hardly at all, surges up and down...

I think my plugs need replacing. Don't have owners or service manual yet. Can the plugs be replaced without having to remove the gas tank? Any tips/hints I need to know about before I start? Thanks again for all the help!!

HI, I just purchased a nice 2001 (black) FZ1 with only 3K miles on it!!! Awesome bike. It did not come with an owners manual. It seems the temperature light is always on - faintly (bluish color) when I start it up and ride. Does this mean there's a cooling problem?...or does the light...
