This is a later production eng. that came with low comp head for use with aprx. 10% nitro type fuels . Pete ended up with my spare that had the two piece no nitro head. (green anodized.) I have a Randy smith pipe I bought for it several months ago. He calls it an Ultra torque pipe. I need to dig through my papers and find his suggested pipe length and RPM settup.
Hi Gordon,
I have two MVVS 49's, the glow one with a green head but sports a new liner with the latest trapezoid shaped transfer ports, Akrobat rear pipe and one that is dieselised, side exhaust and is intended to be side mounted.
Most of the comments that I have read regarding MVVS's centres around the power to weight to capacity ratio, they do seem a tad 'solid' for their capacity but the power they make seems to make up for this - if all of that makes any sense!
Its their solid nature that tempts fliers to put pipes on them, and well ........... put diesel heads on them.
