Well the motor is going to get dropped for a heart and lung transplant.
I just picked up a 2003 Yamaha XVS1100 motor from FleaBay, $600.00.
This gets me the following:
1) 95mm pistons vs 92mm
2) Nikasil lined cylinders vs. iron slug in aluminum
3) Larger cooling fin surface
4) 47mm intake valves vs. 43mm
5) Stroker crank and rods
6) 1100cc vs. 920cc
7) Internal rotating parts that weight about 7 lbs less!
8) Much better squish area
The idea is to use my existing 920 cases (chain vs. shaft drive) and transplant the crank, rods, cylinders, pistons, and heads. Add my existing stuff from the 920; carbs, starter motor, etc.
Then tune with the following:
1) MegaCycle Cams/springs and retainers
2) Deck heads by .025 to increase the compression
3) IgniTech adjustable TCI
Brah-hahahaha!!!!
