Sorry if this doesn't go here.
After being off a bike for about 5 years i bought a 06 yz125 to build for single track.
Took it to a 144.. And my usual woods set up. Loved the bike. Due to work i could only ride about once a month..sometimes 1 every 2-3 months.
Anyway last summer i started to ride every weekend.
But my hands would fall asleep within the first 5 mins.and the ride would just suck for the rest of the day.
So i ended up selling the bike.[due to other reasons].
Now i want to buy another.
But i can't deal with my hards falling asleep and getting arm pump.
Is their anything i can do?
Would going to a 4 banger help?
What do you all think?

I had a set for a few years and they were incredible.
You just have to maintain them properly.
But nothing really seemed to help long term.
Been doing slot of reading on the subject.
And now have a few questions..
Anyone that has switch from 2 to 4 stroke did you notice any difference?
What about grips?
I've read that going to a larger round grip can help as well.
At 39 im an older guy getting older but man im just not ready to give up riding yet.
I always thought i would still be ridding at 60!
Maybe i need to move away from mx bikes and more toward an enduro or strictly an offroad bike.

...here's what I've found.
aluminum frames are the worst, especially the first gen hondas and most aluminum frames from the early 2000's
handlebars with cross bars are no good.
anything 2-stroke over 250cc will vibrate. no ifs, ands, or buts.
some 4 strokes vibrate, some don't. my 2013 SX-F 450 vibrates like crazy, my friends 2013 XC-F 450 doesn't at all.
Fasst Flex bars do not stop any vibrations from the motor - the bars are not isolated by rubber, as the pivot point is metal-to-metal contact.
thin or hard compound grips are horrible.
old tires, even less than a year old can significantly increase the shock and vibe felt at the bars and pegs.
poor riding technique (gripping with hands and not with legs) greatly contributes to hand fatigue and numbness (among other things)
Here is what I recommend for you as the ultimate set-up
KTM 200 sx/xc/xc-w (this is just a great bike anyway)- steel frame and a buttery smooth motor.
A top triple clamp with rubber mounting.
Renthal Fatbar or Pro Taper Contour handlebars
Vibranator handlebar inserts - these little gems work wonders
Renthal Dual compound kevlar grips.
Sharp footpegs and grip tape for the frame and airbox area (to help grip the bike with your legs/knees)
...and make sure your bike is tuned just a tad on the rich side and run good fuel to avoid detonation. both of those things will make the motor have even less vibrations.
...then practrice loosening your grip on the bike and you will never have an issue with numbness or hand fatigue ever again. I promise.
Not super noticeable on the 525sx or 250f but very noticeable on the 2 125's i had them on.
they are great bars, and take away alot of the harshness, but I never found them to do anything for engine vibes. now, go ahead and add these to the other things like rubber mounted clamps and throw in some Vibranators and you have the ultimate "old man" bar set-up, no doubt. I just have a hard time recommending $350 handlebars to anyone unless they have wrist injuries or something like that, especially if we are just trying to get rid of vibrations.
Turns out the only aid for me is riding more.
Pit Row
And i do have carpal tunnel.
Just can't afford surgery right now.
1) The 144 kit. Probably made the engine vibrate worse due to changing its balance with the larger piston.
2) The YZ125 has solid mount bars with no rubber isolators.
3) You tend to ride a 125 at higher RPM's.
250F's tend to vibrate a lot less, plus you can ride them at lower RPM's.
