Here's another thought:
: not many of them around, but if you could find one, it would be a super motor on a SR5.4. It's a 60 deg V4, 1.5 litre, good on juice and bags of grunt. Basically a de-tuned DT100, produced in the mid to late '90s to replace the ageing DT85, before Soozook went all 4-stroke on us.
There again, you could go for a Twatsoo TLDi, Opti or E-tec, if you want a modern 90hp 2-stroke. The new(ish) Soozook DF90 is relatively light if you want a 4-stroke.
Now, have I left anything out?
