I purchased a 2009 T2 that was already turbo charged. WHile repairing some bad workmanship on the welds for the exhaust manifold I noticed there is a home made resrticted fitting on the pressure side oil feed for the turbo. Is this normal? It looks really small ( they used a carb jet) for the speed this turbo spins and I beleive it needs to be removed but wanted to check and see if anyone has the same thing.

Thanks for any insite you can give me.

answer is very dependent on what brand/style of turbo is being used...the use of a restrictor is very common on ball bearing turbos,and some journal bearing turbos ...without the restriction,when oil pressure increases,the flow into the turbo can exceed what the drain can get rid of causing the oil to push past the turbo seals and smoke really heavy...I believe the common restrictor size for garret turbos is .065...as a side note,we have noticed a few of the chinese turbos running without any form of restrictor,that definitely effect the troopers oil pressure (lower it)

just a link I found to show 1 of the styles

Thanks for the information. It is a Chinese turbo and I will continue to run a restrictor, hopefully I can manufacture a new one as they use an odd fitting that is not pipe or JIC.

      2015 Massimo stalled and wont start. oil, new plug, getting gas verified. cranks but does not start
      By Tim n Deb
      Riding out today it acted like it ran out of gas,  stalled and died and would not start.   Towed back to house,  New  plug added this past month,  plenty of oil, getting plenty of gas, battery cranks good.   Trys to kick in and starts but doesnt.   Two days prior while sitting at a idle it died.  Added gas and it started did my ranch chores with it.  But just now it stalled out cranks but will not start.   Tried to find if fault codes came up on the clock like manual says but not sure I am doing that right.  Any and all help apprecated.  Thank you

      MSU 700 Oil Burning
      By Chile
      2018 Massimo 700 MSU. The machine started burning oil all of a sudden. One day fine-- next morning burning oil. Looking for advice. Do I pull the engine to inspect the top end or can it be done with the engine in place? Pro? Cons?
      Any and all assistance is greatly appreciated in advance.

      Which is the best oil to use ?
      By Prepper
      I have been doing a little research on which engine oil is best for UTV engines.  There seems to be some disagreement over using a good quality regular engine oil, and the necessity of using "M2" (or wet clutch suitable) oil.  My understanding is the "wet clutch" suitable oil has less friction reduction properties (hence a more responsive clutch with less slippage).  While less friction reduction properties would seem to be better for the wet clutch... it would not be best for the internal engine parts like camshaft bearings and other moving parts where friction is detrimental and would lead to premature failure.  Some folks swear you need M2 oil, while others say they have been using regular motor oil for years and their clutch is just fine.  Could they both be right ???
      Any thoughts ?

      Oil change
      By Joe Breaux
      Decided to do an oil change on the Massimo ...drained oil, screen was very clean even tho oil wasn't.  Then went to remove old filter.. holy crap ..I tried every tool I have, could not budge it..Went to store and got one of the end cap type..fit nice and tight, put a 1/2 in drive ratchet on it..nope..not moving.  Put a 18 on breaker bar o. It. The inside of the removal tool broke off!!  Had to weld it back together. Put a pipe on the bar for more leverage.  Finally broke it loose..
      I have never seen a filter in my 55 yrs of working on engines so tight..And i was the one who put it on 2 yrs ago.  JUST HAND TIGHT!

      I just picked this UTV up off of Marketplace. It needs batteries. 
      I am installing a single 48v lithium battery. 
      The on board charger, a NOCO Genius GX 4820, has a lithium mode. 
      Has anyone here used this charger on new lithium batteries? I want to be certain of the compatibility before hooking the charger to this expensive battery. **

      I got in touch with NOCO and they told me the charger is fine to use on a new LiFePo battery. 
      Nice charger. Many modes. New ones are running about $550.
