Found this on Facebook today, place known as GBDistribution up in Quebec Canada have just started producing reproduction/upgrade tracks, mainly to fit older arctic cats. (El Tigre 6000 78-79, Pantera 80-81) But they say they MAY fit JD Sportfire, Trailfire, Liquifire... They need further dimensions ...

Thanks! I received the fireplug cdi a cupple days ago & it's missing 2 plugs the square plug is correct but the two round ones are missing has anyone else had the same problem? The hewtech box has a plug for the 76' style engine, which has two square plugs, one for the cdi, one for the hookup t...

I'm quite sure re-wrapping is an option. Now, I'm not sure where you live, but here in Ontario Canada I'm considering sending a stator off an 80 sportfire to a guy in my area who re-winds stators, by the name of "Stator Kev". He mainly does arctic cat stators, but he has done a JD stator o...

The CDI boxes and stators are known to fail on these year Cyclones and Liquifires. Had a CDI failure on my Liquifire... ran perfectly, then I shutter down on the side of the trail, and it completely lost spark sitting there... You can go to CDIBOX.com, they make an excellent, yet expensive CDI box f...

Good. I didn't feel like making any The spark plugs looked fairly rich before anyway. Thanks for the insight Matt

Hey everyone, I just got yesterday putting a fireplug cdi on my 1977 Liquifire 340. On their website, they say you may have to make changes to the timing and jetting. Without making any changes to the timing or jetting, mine seemed to run really good. I noticed the idle was a lot better than it used...

When I had my 1980 Sport Fire back in the day it would start cold like yours. I would start it on full choke and it would fire up on the second or third pull. I would then have to flip it to half choke right away and start riding it at a slow speed. I would then flip the choke off after maybe a 1/1...

Well when it’s warmed up and idling with airbox on adjust idle air screw slowly and pay close attention to when engine runs best or the fastest. Then find out how many turns it goes in. I think if it’s 1 1/2 open you can get a fatter pilot jet 1 1/2 is what the service manual says to back it out to...

I always use a small screwdriver and my finger to measure depth of choke bore and adjust choke cable to match. Then when installed and tightened and gauge pod down the lever should have a little free play. Are you using full choke or just first or half on position? Waaaaiiit... I forgot full choke ...

Did you pressure test needle and seat? Is it flooded, maybe when shutting off the needle and seat leak fuel past and flood engine. I would think if you have lots of smoke when starting that would be excessive amounts of fuel burning out. Correct spark plugs? I did test it and adjust it. Doesn't see...

Was it like this before you took apart? It's impossible to tell. Due to the bad outer seals, pickup line, and coil, it barely ran at all before. It almost always ran on one cylinder, and it would only have a bit of power for 5-10 mins before the bad seal leaked more, leaving it with almost no power...

I have a 1980 Sportfire that is very hard to start in the cold. About 20 seconds of laying on the electric start with choke and it will finally come to life. It won't idle cold. I have to give it throttle a bit until it warms up. When cold it also seems to have quite an inconsistent idle. Once it wa...
