- If you're struggling to get your Trail 90 to start and idle right, or if it stumbles off the line, this video is for you! For the record, my CT90 is a K3 built in 1971 and sold in 1972. It is the only model year with stripes on the downtube cover and the long "T" on the airbox. So classic!!
Previously, I made a video about how I had trouble with my CT90 starting and idling. I showed some basics about the idle air screw and the importance of having a good ignition coil that's correct for the bike.
That video is here if you'd like to check it out.

I just acquired a 74 CT90, and as a COMPLETE motorcycle newbie, this video is excellent and SUPER helpful, THANKS for taking the time to make this! Cheers from Iowa!
Glad I could help!! These are great machines to have some fun with! I hope you enjoy my other videos too!!
It always baffles me when people say they would rather have a carbed bike. "It's simple to repair and maintain." Meanwhile, the EFI bike starts right away and rides away lol. For context, I'm in my mid 40's and a heavy duty mechanic and I fix and repair motorcycles and dirt bikes for fun. Been doin it since I was a kid.
EFI you don’t even need a tuning video unless you’re trying to balance them! Daily riding, definitely easy! Thanks for watching!
Very good instruction!
Thank you!
Great instruction. Hope to use your info soon as I start to work on my herd of step-throughs.
Any luck??
Great video, need some advice, I have a 75 ST 90, stumbles from idle but runs well. When it comes off of WOT it also will sputter. I am thinking I need to lean it out with the throttle valve. All problems go away when I pull out the high altitude knob. Thanks.
So you definitely have a rich condition that resolves with the alt. valve. I’d say jet down but if you don’t have jets try lowering the needle. I’d want to know how much you are coming ‘off wot’. 100-90%??…Jet issue. 100-50%???….needle.
Lowered the needle, bike is now perfect, no stumble and sputter. Appreciate the help.

My 1978 carb is nothing like this one.
True story. You have four screws holding the bowl on? I’m pretty sure you’ve got the better one. Newer is almost always better tech. Thanks for watching!
@@ReMotorcycle No mine has two screws on the bowl. There’s a mixture screw near the intake manifold and the idle screw which doesn’t change the idle speed at all
