You are correct Dan it is the MBX Ultra but I dunno if it is that or the COMP.
Took the motor out yesterday and looked at the piston and sleeve and got a better chance
to check compression---good compression and I see no scratches.
On the other hand from a closer look at it it looks to me it has had at least a gallon-1-1/2 gallons run through it.
It was rough getting it started Sunday cuz fuel was left in there for a week or more. It ran but was a bit rough and I think it had to do with the fuel going bad and some on the tuning side.
I will be cleaning this thing up real good and the tank out real good too.
According to some of the specs I read on this is has the force 26 in it but how can I tell if it has this motor or another motor. The head is purple with OFNA on it and the motor casing shows 3.5 on it which I dunno what that means.
Also how are the force engines??
As for the rest of it---I took a shock off to check that out and it has push and spring on it but when on the buggy it does not push the arm down very well at all.
So I am wondering what would be a good oil and spring to use in them?
BTW---what is the big deal on the electric start with them---I see ppl having problems with it.
Dan, Mark mentioned it to me you had problems with yours.
I am looking forawrd to give it a try at LH as soon as I can.
To be clear on the wheels---it came with 2 yellow ones and 4 blue ones and 4 dirty harrys.
Stock OFNA radio and electronics.
Slim --- Maybe we talked but I dunno who I talked to-to match up your user name here??
Any tips on buggies stuff especially this one would be greatly appreciated.
As for my Mayhem ST---I am have finally had the chance to run this on a off road track and it handles really good. A bit tough on a shorty track but that will get my skills better in driving dept.
The only bad thing is the Stearing servo needs to be upgraded---way too slow and I had to take turn wide and still had bump and grinds. Or I bump it up from 6 cell pack to a 7 cell pack for the RX pack.
I broke one of the turnbuckles but I plan on upgrading those to something more durable.
I did not blow through bearings this time. I had put in better chassis stiffners and a vented flywheel which I think these two had a lot to do with me eating up bearings. In addition I went from a 13t to a 12t gear.
Mark knows I had more run time this time than at the dirt track by my home.
I did do the 10 min main with good results from the motor and not too hot either---I was expecting issues since it had never been run for that long at one time.
