Hey, i have an 03 TE610e with conventional forks and I am going to do a swap using YZ450 forks. My plan was to have a custom stem turned, but I am wondering if the triple from a USD 610 might work? Is anyone able to measure their USD Husky's upper and lower fork diameter at the triple and tell me the measurement? Thanks for the help
54mm upper, 58mm lower on my vernier. Using a 610 USD triple would probably be the best route as you will find inevitably the YZ geometry will be different with a steeper steering head angle for sure, and differing tree length etc.
I think there is a difference between 45mm forks and the actual yoke diameter ... the 45mm is correct but internal as I understand. I physically measured my '09 TE610 with a vernier at the upper and lower tripple.
Thanks for the help, the OD is what I need. You have a good point about the steering angle, I did not think about that.
The thing about the steering angle is that there could be variations in the frame, and there also could be variation in the triple clamp (in both offset and angle). I suspect (but don't know for sure) that the increased rake on 610s is in the frame, not the triples. As such, switching triples won't change this. However, trail is really the big determiner of steering feel, and that is a function of both rake angle and offset. Short story, check that the YZ triples have a similar offset to the 610 triples before swapping them. Obviously the triple from a USD 610 would be a nice easy swap, if everything lines up. No reason that I can see to limit the search to YZ forks either, unless you have a line on some cheap ones, there are lots of good cheap USD forks out there that would work just as well.
Thanks for the info, good stuff to look at. I already have the SSS YZ forks, triple, etc and I think they would perform pretty well on the bike (after a respring etc). I really like the TE for DS stuff, but it is so lacking in the suspension department it gets boring riding, or dangerous depending on how hard you push it. I also have a TE510 shock I am going to add at the same time. Based on some preliminary measurements the forks and shock will add about 2in to the stance of the bike which it really needs for hard off road, along with much better damping . I am also adding an FCR carb in place of the Delorto. What would you guys recommend for a jetting baseline, riding from about 4500-11k above sea level. Thanks for the help
I'm at sea level, but still, I can post my settings. I am running the JD jet kit, so I have that needle. 178 main, red needle 4th clip, 45 pilot, 0.5 or 1 turn out on the screw (can't remember), merge racing AP spring, no o-ring, JD leak jet (60?), accel pump set to nearly zero freeplay. Note that the stock 610 FCRs have the accel pump leak jet plugged from the factory, and I never could get mine to run right until I put the leak jet in.
Ok so the YZ forks are 56mm upper and 59mm lower. What do you guys think could the 610USD triple work or is the 2 extra mm going to screw it up?
2mm is a lot. I do not think that you will have any luck getting those tubes into the triples. A good machine shop might be capable of boring those out for you, probably still cheaper than a custom stem, maybe.
