Hi there,

I'm afraid I don't know anything about jetting the older triumphs, I will move this thread into our classic, vintage and veteran forum, where there are some very knowledgeable folks on these models.

Thanks

This is a little different than ordering a 'jet kit' for a CBR ... FIrst off, you're gonna need to take the carb(s) apart and thoroughly clean and do a 'rebuild'. If you do the 'complete' rebuild it will include your needle jet, needle and float needle. As far as the main jet goes, *if* the bike needs a different main jet, you'll just order the jet(s) by their size. Check the Amal tuning guide Here for more info. The Amals are notorious for wearing the slide bore. You can have them bored and sleeved, replace the body, or get new carbs readily.

Hi there,

I'm in Denver too. I haven't had to rejet my bike - a 72 TR6C - only one carb instead of two, but still the same basic idea.

Where have you got the clip set on the main jet(s)? If memory serves correctly, I've got mine set at the 2nd notch down (stock jets as far as I know). The main jet doesn't even really do anything until you get over 3/4 open throttle, so you might be on a wild goose chase if you change your main jet to resolve idle issues.

Check some of these links:

If you'd like, shoot me a PM and I'll help you take a look. However, I make no claim to be even close to an expert. Just lucky with a hair of mechanical intuition. I learned a LOT about my bike since I got it running this summer and it was running like a champ last time I took it out in December. Might be taking it for a spin this weekend (we're looking at close to 60 degree temps!) if the battery is still good. FYI, I've got room in the garage and a decent set of tools. Just let me know.

Two good local places to go for parts and such are Isles Motorcycles over off 29th and Sheridan - Greg Isles has been a nice guy to work with: http://www.islesmotorcycles.com/about_1.htm

or Arvada Bike Shop over at 66th and Wadsworth - Dave is the dude: http://www.arvadabike.com/bike2/motor.htm

Greg works on bikes and is really busy. Dave doesn't and isn't.

I'm probably one of the luckiest Triumph owners in America. I live practically right between two awesome Triumph parts dealers. :D
