Hello,
I'm fairly new to posting on these forums. I have been reading for a couple years now since I bought my first ski (js550). I've since owned an x2 and now have 4 waveblasters!
I purchased a ski recently that has some engine work done and it was never completed and has not run. The known engine specs are as follows;
61x case
61x cylinder that appears to have been ported by Greater Yamaha
Greater Performance head w/ 33cc domes
Factory B pipe with mod chamber
New pistons with .5mm bore
Riva flywheel
Came with a stock single intake and sbn44 as well as 2 (riva and r&d) dual carb intakes
MSD enhancer installed
Tested at 210psi compression
I have a few questions regarding this set up...
1. Any info on the greater yamaha cylinder? Likes? Dislikes?
2. Are replacement domes still available for this head? I would like to drop compression significantly in order to run pump fuel 175-185ish
3. Should I stay single 44 or dual 44? I know this could be greatly debated but I'm looking to have a fun low end power rec/freeride ski that is easy to tune and reliable. I know I'm asking too much. Lol
Please review the pictures and let me know what you think!
Any help is greatly appreciated. Thanks in advance
