Bought the new Picco P Max .21 for the T-Maxx. It's supposed to be a drop in for a T-Maxx but not quite! Sure the exhaust, clutch and pull start fit but the chassis plate holes for the motor mount had to be slotted to get the clutch bell gear forward closer to the spur.
Then the end of the crank hit the transmission housing stopping the clutch bell gear from lining up with the spur. I had to grind the trans housing so the engine could move further forward. Now the crank has a few thousandths of clearance to the trans case and the gears are almost perfect. It will take some crank grinding for a perfect fit. If I start to loose spur gears... I'll just have to cut the shaft.
Other than that it was a smooth install. Had to work with the throttle linkage adjustment to get WOT, but that's the easy stuff.
Grinding the trans housing for clearance.
I did some more slotting and filing after break in... not to bad now.
This is the adjustable BUKU clutch. I installed the stock clutch for brake in as I wanted just to focus on the engine and not trying to get this clutch adjusted at the same time. After a gallon I'll install the BUKU (darn thing was $60 lol)
I love the low profile head that barely exits the body. It should also keep a lower CG.
Running the first few tanks after the Traxxas style break in with TRX Top Fuel for it's high oil %. Soon switching to Byrons 25% - 9%. I have the THS tuned pipe on the way also.
