well long story short im building an R for someone that basically has an unlimited budget, and its going to be in my old laeger chassis, with a stroker 350pv, i know that something like this will be very hard on the tranny, so i was thinking about yukons, but ive heard mixed reviews on them, so would you say get them, keep it stock, or get another type of gears(if there is another type)

I would just use stock Honda tranny gears and replace any of the gears that look warn. Typically 2nd and 3rd gear on the countershaft side that get bad. I think like 6th gear on one of the sides takes some abuse as well since it's part of one other gear I believe 4th but it's been awhile. The 370 I had ran for years without any tranny problems.

The Puma I am building I did go with the yukon gear set but my guess is it's going to make a bunch more HP than the 370 did. If you want to spend the money for a yukon gearset, you best be buying because when I got mine (Feb 08) there were only 36 sets left and when they are out, that's it forever. Yokon isn't going to have them made any longer from what they told me.

I think it depends on your type of riding and your riding style. My uncle had a 370 and only dune rode it and did a couple sand races. He tore up everything on that bike except the tranny. He also never shifts using the clutch. Just jams em' up and jams em' down. He only uses the clutch when taking off.

the riding style is pretty aggressive mx riding so there will probably be a fair bit of pressure put on it

If the guy has an unlimited budget, I'd say get the Yukon's. I know Baldwin has a version as well, but I don't know if they offer them anymore. Like Randy said, another option is to get new OEM gears or use his current gears and have them cryoed.

I broke 3rd gear and some other parts in my tranny last sunday so now I have the same dilemma, yukon or not? Now is the time to get them, cuz it sounds like they won't be available much longer. So do you guys recommend the yukons and who has the best deal on them?

I got mine on E-bay and it also included a Honda countershaft gear for 5th and 6th gear for $400.00.

Honestly though, I would just buy the stock Honda gears for anything less than 80 HP. If you have a original Honda gearset in your tranny, these gears are made of a lesser steel than the new Honda gears. The material they use in the replacement stuff is better quality and are good and hard. I had a 370 for years and banged the gears, didn't use the clutch to shift, etc etc and never had a problem at all. I just don't think the Yukon set is worth the money unless you are going to run big power. Just replace the gears that look suspect along with 2nd gear for sure and you will be good to go.

remember too that the gears that broke are probably 20 years old. its not that theyre weak its that nothing lasts forever. i broke 3rd gear on my 310 once. just bought the OEM replacement and never had another problem.

You could be right about the 20 year old part. I know I replaced 2nd gear about 3 years ago. I know i replaced one of the others about 8 or 10 years ago. Probably 2nd or 3rd.

I'm hesitant on the yukons cuz if I buy them now and break one later, their might not be any to replace them with. Then I'll be going back to OEM anyway. One of the guys from ESR said they haven't seen any of the yukons break yet, but they are going to quit making them.
