Does anyone have a similar issue. When i am cruising at moderate speed with no real load on the drive train from the engine, I am getting and hearing a vibration throughout the machine. When I am in 2 wheel drive I don't get, only in 4 wheel or 4 wheel diff lock. My pioneer is soon ready for its first service, just wondering if anyone else has an issue before I take it in.

Yep. More vibes in 4wd.

Would you say that it is normal. I had a Big Red before this and never had the issue

 

[DG Rider]

Yes.
The engine is rubber mounted...looks like a Harley floating around. Add to that the fact that the front and rear tires are never exactly the same actual size....

Put it under a hard hill climb and it can vibe pretty badly as well.

Under load there is no vibration or noise

Mine smooths out when it shifts into third gear. Other wise it does vibrate a lot. Of course a single cylinder makes it rougher.

This is a copy of my post from Oct last year, sounds similar to what you got going on...

Had my 4 person on a decent ride this weekend. Found some extra vibration at around 35kph when driving in 4wd. Smooth as silk in 2wd. Wouldn't normally be driving 35+ in 4wd but forgot it was in. Though I had an issue brewing till I switched back to 2wd and all was well again...

Had her over some pretty rough/rocky terrain. Way easier on the back and arms than covering the same are on a traditional ATV and definitely a lot warmer

Cheers,

Thanks guys for the piece of mind. Will be taking it in soon for its first service, I will still ask them about it just to get it on record incase it does turn out to be a serious issue. You never know!

Um diff lock and 4wd you will see vibrations. Thats only when no tire is giving way aka traction. Is the tires slip the vibe goes away. Dont recomend running the front locked in unless you need it. It can wear your bearings and gears faster unless your running the same size front and back. Also if you take out of duff lock and going on road be sure to stop and turn the tires 1/4 left and right youll here the mechanical locking mechanism spring back into place.
