I have installed two of the www.ht-racing.com 350 kits. The bike is uncomparable to what it started out as. The 350 kit makes the bike be what is should be. It has a nice light feeling ride with great trackable power able to lift the front end with a crack of the throttle. I highly encourage people to try this kit.
I have used the HT-Racing 350 kit. The 300 kit is by Thumper Racing, I think. I have experience only with the HT-Racing mods. HT has both a 305 kit and a 351 kit.
KTM CHRIS, I was going to PM you because now I'm starting to feel like an idiot. But I figure someone else on the off chance might also be as lame on this info as I am, so here goes:
Now that you've thrown 351 into the mix, whats the diff between the 350 kit and the 351? And HT Racing is the only one who makes them? I am considering one of these kits for my 250 but I do not know which one. Is this a modification people do on their own or is it recommended to get it done at the KTM shop? Thanks.
Getmetoca: My riding buddy and I both have the HT Racing 351cc kit in our 04 250RFS.. Huge difference, like KTM Chris said. Bill at HT Racing can either do the work or a good KTM shop should be able to do it easily. The 305cc kit is more for the tight woods and the 351cc kit works great in the SoCal desert. I went up two teeth on the counter shaft sproket without any problem.
Zio,
I don't even remember posting this question.
I totally forgot. Anyway, I have been considering a 250 4stroke of some kind. As you now know, the 250 I bought was a 2 stroke and I like it a lot, especially in the mud. I still ride the 200, but I will be racing the 250 this year.

Hey Dave...I have a stock 2002 KTM 250 EXC rfs and am about ready to order my 351 kit from HT. I ride Michigan woods, two-track and some southern Ohio/Indiana single track, occasional Dual-Sport. Is the 351 kit the best choice for this type of riding, or am I going to wish I'd gone with the 305?
